Fill Left Rear Wheel with Liquid:

The Left Rear Wheel must be filled with liquid. Alamo Industrial recommends a CalciumChloride Water Mixture. The recommended Ratio of a 30 / 70 mix (30% Calcium Chloride and 70%Water), this mixture will add weight at about 10.5 lbs per gallon. Follow the Mixture proceduresfurnished by the Manufactured of the Brand of Calcium Chloride that you are using. It is alsorecommended that a trained person installs the calcium Chloride. Calcium Chloride must be added inaddition to the Steel Wheel Weight and the Counter Weight that hangs on the Left Side. It is Notrecommended to use straight Water in the Wheel as this would not provide protection against freezing.A 30/70 Calcium Chloride Water mixture provides anti-freeze to approx -50 deg. F. below 0.

Installing Pump, Pump Drive Components and Hydraulic Tank:This Section covers installation of Pump and Pump Drive Components, Pump Assembly and

the Hydraulic Tank. Some precautions must be followed during the Assembly Process and before unitis ever started for the first time.1. Tractor must be disabled to prevent accidental engine start and prevent damage to components.2. All Fittings, Hose, Cylinders, Tank must be kept plugged at all times, No part of the Hydraulic

System can be left open at any time during mounting process, this will keep system clean.3. All Tools, Work Area, Components and Workers Hands must remain Clean when working on

any part of the Hydraulic System.4. All components should be rechecked for tightness at least twice, Hose routing also double

checked.5. Shown in Figure 1 is the schematic for the pump mounting components, showing the driveshaft

going through the front bolster of tractor. Located these components in the packing crate. (SeeFigure 1) NOTICE See Parts list as to which driveshaft is used on which tractor model!

Pump & Driveshaft components :

1. Preparing Pulley Adapter, The pulleyadapter has US standard size holes, the EngineCrankshaft pulley uses Metric Bolts which will notgo through the pulley adapter hub (P/N 02702900).The Pulley adapter will need to have the steelbushings in the pulley adapter reamed (Drilled)out to 31/64" hole, this will allow the metric bolts tofit the holes. Use a drill press and clamp theadapter securely when drilling them out. Keep thealignment straight and do not bore them oversize(See Figure 2).

2. Pulley Adapter Spacer, The pulley adapterspacer (P/N 02979649) is installed between thepulley adapter (P/N 02702900) and the crank-shaft pulley (See Figure 1 & 3).

3. Insert Pulley adapter into Tractor EngineCompartment. This can be a difficult job as thereis not a lot of room to see after you get your handin the opening (See Figure 4). This is easier if twopeople work on it. On the bottom side under theengine there is a hole in the front bolster that youcan reach to start the bolts in the pulley adapter,make certain to start all the bolts before tighteningany (See Figure 5 & 6).


Figure 2

Figure 3

Figure 4 Figure 5


4. Tightening Pulley Adapter, The pulleyadapter can be tighten by inserting a wobble socket(19 mm Socket) through the driveshaft access hole(See Figure 6, 7 & 8). This is difficult for one personas it is difficult the align socket with bolt heads, asecond person can assist by aligning the socketfrom the side of the engine. The four bolts for thepulley adapter can also be tighten from the under-side by inserting a 19 mm wrench up through thehole in the bottom of the tractor bolster on somemodels. DO NOT over tighten the four mountingbolts as the bushings in the bolt holes are set inrubber. If you need to turn the engine you can installthe splined shaft into the pulley adapter and thespline coupler on the driveshaft, turn the engineusing a strap wrench on the spline adapter. DONOT try to turn engine using any kind of wrench onthe splines of the shaft as you will damage thesplines on the shaft (See Figure 9).

5. Install Pump Driveshaft & Coupler. Installthe pump driveshaft )P/N 02979634 on 2 WD or02981047 on 4 WD models) and the spline coupler(P/N 02957635) into the front bolster hole and intothe engine crank shaft adapter. Make certain thatthe shaft is engages into pulley adapter. (See Fig-ure 9)

6. Install the Pump Mounting Plate. The pumpmounting plate (P/N 02979673) will only workmounted one way (See Figure 9). The two top holesare for Allen head counter sunk bolts and the twobottom bolts are hex head bolts. The mount platemust be installed this way because of the pumpmounting over the two top bolts (See Figure 9).Torque the mounting bolts as according to the bolttorque chart in the general information section.

7. Install the Pump. The pump asy (P/N02961826) will install with the single port (SuctionPort) to the LH side and the dual port (PressurePorts) to the RH side (See Figure 10). DO NOT takeshipping plugs off of any fittings or hoses until thehoses are ready to be connected, this will keep thehydraulic system free of contamination.

Frame Rail Set Up

The Frame Rail Set UP. The Frame Rails for the A-Boom will be set up on the tractor,positioned, measured but not welded. The A-Boom High frame is set on to Frame Rails,positioned and leveled. After all is set up and positioned it will be Tack Welded in Place on Tractor.Then it will be disassembled and welded up on the Shop floor. This is done to ensure better weldsand to enable the parts to be turned so the components can be Flat Welded. It has been foundthat this will make the components stronger. This also gives a chance for all frame componentsto be test fitted and broken loose during this trial if another component makes the previousinterfere with something. This also will make paint touch up easier.

The Tractor should be covered and protected from Sparks from the Welder and Grinderat all times. It will be your responsibility to protect the Tractor and its components. DO NOT WELDor GRIND near any Glass or Painted Surface unless it is protected from sparks, these Sparks willdamage any surface.

The purpose for Setting Frame up, tack welding it then removing it, is because with theamount of Welding that will have to be done these frame components will need to be repainted.The repainting is easier with frames off. The Frame components are shipped already painted butthis is to protect the metal, plan on repainting them after welding. The frame Rails can be mounted,tack welded then removed to weld and paint or left on the tractor and welded, this is because allcomponents are pre-welded to the frame rails with the exception of the front mounting plates, thisdecision will be up to the installer. The High frame will have to be removed to be welded, this isbecause the under side of mounting tubes must be welded to high frame and this cannot be donewith it on the tractor.

DO NOT weld any frame or component until instructed to do so in the instructions. Readthrough this entire instruction book to be familiar with which part goes where and when.Constantly keep in mind that when mounting components that you must be able to raise the Hoodwith out interference from the mounting components. Also make certain when mounting unit thatyou DO NOT mount components where they will interfere with the removal of the tractor engineair cleaner. This should be checked as the assembly goes along and before any final welding isdone.

DO NOT try to man handle large components alone, one slip can break a window, damagea hood or worse. Note the order of assembly of other Assemblies, example the Pump Drive Shaft,Front Rail Supports, Rear Stack Valve Modifications and Joystick Assembly are assembled toTractor before the frame rails. This is because some components will be in the way of others afterthey are assembled..

Frame Rail Assembly:



Frame Rail Installation

RH & LH Frame Rails. Shown below are example of Frame rails, There is a Right and LeftFrame Rail, They will not interchange from side to side. LH must be mounted on the Left and Righton the Right. To ID which is which, the easiest way is to look for the Counter Weight Mounting Tubes(See Figure 1 Item 2), these are welded on to the LH Frame Rail Only. The Rail Mounting Pad (SeeFigure 1 Item 4) is loose and not welded to the front of the Frame Rail until final assembly.

Frame Rail Assembly: (continued)

Note:Item 3 is welded to both LH and RH Frame Rails from the factory. Item 4 will be welded

on during assembly procedures. Do not weld on any components until instructed to do so, thencheck instructions carefully because some components are only to be tack welded then removedto be welded later.

Actual Tube Design may vary from drawing above. Shown above is a general FrameRail Weldment. While Frame Rails may be designed different the mounting process will bethe same.

3 Point Arm Stabilizers on tractor will have to be removed when mounting Framerails and will have to be modified to be used again. This modification will be customersresponsibility.

High Frame Mounting Tube Components. (See Figure 4) These Components are Sitting inapprox. position of assembly to illustrate where they are to be when tack welding them. Space is leftbetween them for Illustration only, they will be closer together when assembled.Also See Figure 3 on previous Page.

High Frame and King Post Frame Sub-Assembly. (See Figure 5) The High frame will comewith the King Post Sub-Assembly built to it. The 2 Wheel drive and 4 Wheel Drive High frames aredifferent and will not interchange between 2 WD and 4 WD Tractors, the 4 Wheel drive High Framehas the King Post Mounting welded higher up on frame than 2 WD Frame. DO NOT try to use a2 Wheel drive Frame on 4 Wheel Drive Tractor or vice versa, it will not work.

Hydraulic Tank, The Hydraulic Tank is mounted on the LH side of High Frame. It will bemounted by the Mounting tubes that are welded to the High Frame and the Tubes that are weldedon to the Hydraulic Tank. There will be long bolts with Allen Heads that will be inserted down throughthese tubes.

Tank Mounted Counter Weight. There is a tank mounted counter weight that will bemounted on to the Hydraulic Tank using Allen Head Bolts. There will be a cover that bolts on overcounter weight.

1. Lay Out Components in Display. It is helpfulto lay out the component in as neat a display aspossible. Lay out the Bolts according to size andlength. Lay out the Nuts and washer by size. This willallow you to see how many of each part as you usethem and help to identify any missing parts. (Seefigure 6) Keep in mind all through assembly thatthere are components on the tractor that have tobe accessible for maintenance and the hoodmust be able to raise high enough to clear them.The Tractors engine air cleaner is the most com-mon over looked clearance item.

2. Front Frame Rail Supports. These FrameRail Support Mounts (P/N 02973159 LH or RH arethe same). It is easier to mount the Pump DriveShaft before these Frame Rail Supports. There aretwo spacer plates (P/N 02973159) used, one oneach side between rail support weldment and tractorbolster (See Figure 7) There are 4 bolts that gothrough Frame Support weldments and into thetractor bolster, install the 4 retaining (New Bolts) thathold the Rail Support Weldment on but do not tightenthem until all 4 bolts are installed. Tight the mountingbolts for Frame Rail supports and pump guard (ifused) now . Install the LH and RH which are thesame weldment (See Figure 7).

3. Front Rail Mounting Pad. Note: The illustra-tions may or may not be of the model tractor you areworking with, the illustration are to depict the proce-dure not model tractor as the installation of parts willbe same. There are two of these Rail Mounting PadsP/N 02725900; one is used on the left and one on theright. These Pads are the same so it will not matterwhich goes on which side. (See Figure 8). Set thePad down over the Front rail Support aligning thefour holes in pad with the four holes in frame railsupport. . Insert the four Bolts into the mount pad andplates on front support mount (See Figure 9). Installa nut on one or two of the Bolts but do not tightenthem, the Bolts are only installed to prevent the Padfrom moving side to side.

Installing Frame Rails: (continued)

4. Locate RH and LH Frame Rail. There aretwo different frame rails, RH and LH. Start with eitherone you want, for illustration we started with the RH(See Figure 10). Remember the LH is the one withthe Oil tank Mount Tubes welded onto it, (SeeFigure 1)

5. Prepare Tractor Axle Housing. First look upunder Tractor at the rear axle where the frame Railsmount , if you see holes in the Axle castings on bothLH and RH side that have plastic plugs in them. ThePlastic Plugs will have to be removed now as theycannot be removed once the Frame Rails are inplace (See Figure 12).

6. Installing Frame Rails. Using a Hoist, lift theframe rail and slide it into place under the right rearAxle. Hold the frame rails as shown to prevent it frommoving (See Figure 11). Using a Floor Jack (SeeFigure 13) support the Frame Rail up under theAxle. Note: the RH and LH Frame rail will install thesame so you can work either side first. Extremecaution must be taken to prevent the rails fromhitting the tractor during this process, it is best towork as a two man team.NOTE: Tractor Model is for illustration only and maynot be the model that you are mounting mower to.

Use Extreme cautionso that Frame Railwill not hit Cab /Hood & causedamage. It is recom-mended that this bea two person job.




Installing Frame Rails: (continued)

7. Installing Frame Rails. Using a Hoist,lift the frame rail and slide it into place under theright rear Axle. Hold the frame rails as shown toprevent it from moving (See Figure 12). Usinga Floor Jack (See Figure 13) support theFrame Rail up under the Axle. Note: the RHand LH Frame rail will install the same so youcan work either side first. Note: The frame railswill have tobe removed after the aligning andthe tack welding is done.

8. Install first Frame Rail to Tractor & RearAxle. The Frame Rails Mount to the rear Axleof Tractor. The RH Side has Longer Bolts thanthe LH Side does. This is because the AxleMounted Boom Rest will also mount here usingsome of the same Bolts. For now use shorterBolts to hold Frame Rail up to Axle while youfinish the Pre-Installation. (See Figure 14).

9. Install the other Frame Rail. Theother frame rail will install the same as thefirst did. DO NOT do any welding at thistime.

10. Frame Crossmember. Locate theFrame Rail Crossmember (See Figure 2 &15). This will bolt between the LH and RHFrame rail under tractor using four bolts andnuts. The mounting tabs for the cross memberare to be welded to the frame rails (See Figure2). Slide the crossmember in between the tabsand insert the bolts, It is best to support this asywith a floor jack until you have tack welded thecrossmember support weldments to the framerail. Start the bolts but do not tighten them atthis time as the supports need to be tackwelded to the frame rails..

Frame Rail InstallationInstalling Frame Rails: (continued)11. Align Frame Rails on Front Mount Pads.Locate the Front Frame rails on the mount pad sothat there is room for the Bolt heads to clear theFrame Rail. Here we have wedged a Screwdriverwith a 1/4" shank between the Bolt Head and theFrame Rail. Anything about that size can be used tokeep enough distance so bolt can be removed andreinstalled without interference. Use a C-Clamp tohold it in place when aligned. Do this on Both the RHand LH side. (See Figure. 20) Do Not weld framerail to pads at this time, high frame needs to beset down over frame rails before they are welded.

Pre-Installing High Frame:1. High Frame Shipping Pallet. The High frameis shipped bolted to a Pallet, Do not unbolt this fromthe Pallet until the Hoist has been connected to theHigh frame. The Hoist must be supporting the weightof the High Frame before any of the bolts holdingHigh frame to pallet are removed. There two liftinglugs welded to the high frame that are used to lift it.(See Figure 17)

2. Prepare High Frame for Lifting. There aretwo lift lugs welded to the top of the High frame forlifting it (See Figure 17). These Lugs will lift the bareHigh Frame straight if the chains are shortened onRH side to compensate for the weight differencebetween the two sides. Balance the load (SeeFigure 18) and lift High frame level. High frame mustbe level when lifted over Frame rails.

3. Level High Frame. Use two magnetic Levelsas shown. These magnets should be installed beforelifting High frame.

The First Magnetic level is put on the Top ofthe High Frame on the Bottom Side (See Figure 20).This level will allow you to level the frame from left toright without having to climb up later to use a Levelthat you hold.

The Second Magnetic Level is put on the KinPost Pivot toward the front of the tractor so that it willlevel the High Frame from front to rear as shown(See Figure 19).

4. Lower High frame down over Tractor.This is a two man job in order to keep control ofHigh Frame on both sides of tractor (See Figure22). Lower the High Frame down over the Framerails (See Figure 23) slowly, as it must straddlethe Frame Rails (See Figure 23). Lower HighFrame until the top of the High Frame should beno higher than the cab of The Tractor maximum.And high enough to have sufficient hood clear-ance (See Figure 24) . Another mark to look atis the Horizontal tube of the High frame should beparallel up and down with the Frame Rail Tube asshown on next page (See Figure 29).

5. Check High Frame for Level. Check thetwo Magnetic Levels that you installed earlier.The Top Level should be from side to side of theTractor (See Figure 19 & 20). The level on theKing Post Pivot Pin should be level making HighFrame Level straight up and Down. Leave theMagnets Levels on the High frame, as you willhave to check them again later. DO NOT do anywelding at this time.

6. Secure High Frame to Frame Rails. Se-cure the High Frame to the Frame rails with C-Clamps on both sides (See Figure 25). Do notweld anything at this time.

7. Align High frame to Frame Rails. TheHigh Frame Vertical Tube should be as directlyabove the Vertical tube of the frame rails aspossible (See Figure 26). The illustrations infigure 26 shows the High Frame not directly overthe Frame Rail Vertical Tube, try to get it asdirectly over it as you can.

The height of the High frame should be nohigher than the Cab of the Tractor. The horizontaltube of the High Frame should be just above theheight of the horizontal Tube of the Frame Rail(See Figure 25 & 26)

Clamp the High frame to the Frame Railwhen aligned and leveled. (See Figure 25). DONOT remove the hoist, Leave the Hoist con-nected to the High frame for safety and additionalsupport.

8. Recheck all alignment points. Recheckthe alignment of the Frame Rails and High Framefor level mounting position. These componentsmust be aligned now before any Tack weldingbegins. This is critical to make certain that thehigh frame is in alignment and level. See Figures26, 27 & 28 on next page for alignment. Makecertain Hood clears frame when raised andthe engine air cleaner can be removed forreplacement.

9. Install Mounting Tubes . Loosely bolt theFront Angle Mount end of Mounting Tube (SeeFigure 26, 27, 28). Slide 1 Mounting Tube in ontop of the Frame Rail on each side, the end thathas the Angle Mount bolted to it goes to the Backtoward the Tractor Cab. The mounting Tubeshould be slid back until the end of mounting tubeis back to where it can be bolted to the lug weldedto the frame rail . (See Figure 27). Do Not TackWeld any components at this time. Note: in figure27 note the location of High Frame Tube Heightas compared to Mounting Tube Height, this is theway that it will appear as looking over the Hood ofthe Tractor toward LH Side.

Frame Rail InstallationTack Welding Frame Rails:1. Tack Weld Frame Rails to Front Mounting Pads. Check to make sure that the Frame rail is stillaligned on front rail Mounting Pad, Frame Rail should not interfere with the Mounting Pad bolt headsCheck the LH and RH Frame rail (See Figure 30). If alignment is correct Tack Weld the Frame RailMounting Pads. (See Figure 31). When tack Welding use 4 good tack welds per Frame rail, 2 on eachside of Tube. (See Figure 37). The C- Clamp on The Frame Rail Tube at the mounting pad can be lefton till later.3. Go back and check. Make certain you have tackwelded the Frame Rail to Mounting Plate (See Figures 30through 32). Make certain that frame rails are aligned so highframe is centered and frame rails are wide enough that thereis no gap between frame rails and high frame. When this isset correctly you can weld the frame rails to the front mount-ing plate. The decision to remove the front rails later to paintthem where you welded the mount plates to them or paintthem with them on the tractor is up to you. (See Figure 33).The mount plates should be welded to the front mount platein three places, down the sides and across the front.Tack Weld Mounting Tubes to the High Frame:1. Tack Weld Mounting Tubes to High Frame. Checkalignment and height of the high frame to make certain it iscorrect. Make good Tack welds for the mounting tubes to thehigh frame in three places on top and three places on thebottom. This will need to done on the LH side and the RH side.(See Figure 34). Note in figure 34, tractor is covered toprotect it from the sparks of the welder, this is important toalways protect the tractor from these sparks as they willdamage paint and glass.Welding.:1.

High Frame Installation

1. (continued from previous page). to take High frame off, so that the Weld can done as strongas possible and in places that you can’t get to with High frame mounted on Frame rails. This is alsorecommended so Assemblies can be turned while welding to get maximum quality welds. In figure36 the mounting tube is welded to the high frame with a continuous weld all the way across the top.2. Welding Mounting Tubes all the way around. The Mounting Tubes must be welded to theHigh Frame all the way around on the top and the bottom. These should be good flat welds that havestrength. This welding should only be done by an experienced welder, Turn High frame as requiredto weld all the way around with strong Welds.(See Figure 36, 37, 38 & 39). These must be strongwelds.

Remove High Frame for FinalWelding.: (continued)3. Check all Welds around High Frame toMount Tubes. Make certain that all the weldinghas been done to connect mounting tubes to highframe. Now would be the time to repaint aroundweld on the high frame and mounting tubes.Clean all welded areas and touch up paint. Notein figure 37 high frame is not welded, this is leftunpainted for illustration only, the high frame youreceived should already be painted. (See Figures36, 37, 38 & 39) DO NOT reinstall High Frameuntil Boom Rest and Axle Straps have beenmounted.

Re-Install High Frame:1. Re-Install High Frame on Tractor. TheHigh frame should be welded completly and thepaint touched up around the welds. Lift the highframe with a overhead hoist and lower it downover the frame rails until the mounting tubes areresting on the frame rails (See Figure 39A). Installthe clamping strap (Except for the ones that werecut and welded to mount tube and frame rails)and bolts. Tighten the mounting strap bolts onbothe RH and LH side. DO NOT remove theoverhead hoist until high frame is securly bolteddown (See Figure 39A & 40A)

Install Hose Holders:

1. Install Hose Holders. The Pictures showthe hoses already in the holders, but they are notinstalled as of yet, they are only shown installed asreference and for illustration only.

The hose holders are weld on rings that aredesigned to have the hoses run through them tohold the hoses in place.

These hose holders are welded to the frameas shown in Figure 44, 45, 46 & 47.

Figure 44 is on the right hand side of thepump protector and will have the two pressurehoses from the pump through it

Figure 45 is welded on to the crossmemberacross the bottom under beneath the tractor be-tween the two frame rails. This holds the return hosegoing back to the tank

Figure 46 shows the hose holder on the RHside of frame rail for the return hose going up to thetank. ( the return hose at tank will be the large hosethat connects to the filter at the tank.

Figure 47 shows the hose holder for thesuction hose going to from the tank to the pump onthe left hand side of tractor.

DO NOT Attempt to weld these hose holderswith the hoses in them, the hoses are only showninstalled as a reference.

Boom Rest & Axle Strap:

1. Install Boom Rest The Boom RestWeldment bolts to the RH rear axle using thesame bolts that hold the frame rail to rear axle.The bolts for the RH rail will be longer than theones used on the LH rails. The Axle strap boltswill be 1" longer on the RH side, the under sidebolts will be 30 mm longer. You must support theRH Frame rail with a heavy jack stands. It is bestto jack the frame rail up and put the jackstandsunder it from the under side while installing theBoom rest Weldment to the RH Axle. DO NOTremove any bolts until frame rail is supported withheavy enough jackstands under frame rail. (SeeFigure 49).

2. Install the Boom rest Plate. The boom restplate bolts to the boom rest weldment at the top,there are sets of holes to allow the plate toadjusted inward and outward. It is best to mountthe plate as far out as possible and readjust afterassembly has been completed. (See Figure 50,51& 52).

3. Before Installing Boom rest Tab to Boom.Later in another section of this manual there willbe a section on how to locate the correct positionand in stall the boom rest transport lug.

Boom Installation

Section 7



Boom InstallationBoom Preparations For Installation :

1. Prepare Boom. The Boom will be shippedwith most of the components attached, including thehoses (See Figure 1). The Boom will be wired to-gether at the ends, this is done for shipping (SeeFigure 1).

2. Lifting Boom. It is best to use an overheadhoist to lift the boom (See Figure 2 & 9). This isrecommended that this be a two person job as theweight and the amount of maneuvering that willneed to be done. Once the boom has been lifted cutthe shipping tie wire and remove the wire (SeeFigure 1 ).

3. Remove the Boom Mounting Pin. The boommounting pin is installed in the boom. It is retainedwith a nut. Remove the nut and remove the retainingpin (See Figure 3). Note the hoses for the boom willbe hanging down from the boom if they have beenpulled out. Be careful not the damage these hosesduring boom installation

4. With a hoist raise the Boom Arm See Figure7. Step (1) and lower onto the King Post (2). Alignthe Boom Arm and King Post with the Lift HingePoint. Insert Main Pin Bolt (3) into Boom Weldmentand Turning Arm. Attach Lockwasher (4), Washer(5) and Bolt (6) and tighten (also see Parts Sectionon the Boom Assembly) (See Figure 4, 6, 7 & 8)

Figure 1

5. Hoses on Booms are shipped folded backinside Boom. Hoses must be pulled out and movedto clear, these must be watched so as not to dam-age them (See Figure 3, 4 & 5)

6. Installing Boom Mounting Pin. The boommounting pin can be installed when boom is alignedwith the pin hole (See Figure 6 & 7).

7. Cutter Motor Control Valve Assembly. Checkto make certain the cutter valve has been installedfrom the factory on the LH side of High Frame, it willnot have the Hoses attached, this will be done later.Do not remove the caps from the cutter valve fittingsuntil the hoses are being connected (See Figure 6).

Boom Cylinder Installation :

1. Pull the Lift Cylinder out to its full stroke, toaid in the installation of the Lift arm (See Figure 7).When Pulling Cylinder Out, attach a Hose to the Rodend and lay the Hose in a drain pan. This will catchany Oil expelled when Cylinder is pulled out.

Note: Additional support maybe need at the end of the Boomto aid in installation.

2. Attach the Rod end of the Lift Cylinder(See Figure 7 ) Item (7) to the Lift Section withPin (8), Bolt (9) and Nut (10) (also see PartsSection on the Boom Assembly in figure 7.

3. Attach the Swing Cylinder . The SwingCylinder attaches to the King Post on the RodEnd and to the High frame on the Butt end ofcylinder, There are two holes on the High framethat cylinder can be connected to. The outerHole is the one that cylinder pin should be putin for a rear swing A-Boom. A Forward SwingA-Boom is rare, majority will be rear Swing(parks to the rear for Transport.) (See Figure10 & 11).

4. Leave Boom Supported by Hoist untilBoom is connected to King Post and all cylin-ders attached. (See Figure 2 & 7). The Boomwill have to be lifted again when Head is in-stalled. Do not lift Boom with Hoist if the Cylin-der hoses are open, the Cylinders are built withthe internal components covered with Oil. Ifboom is raised by hoist while these hoses aredisconnected oil may be forced out of end ofcylinder ports on to the floor, it is best to makecertain the hoses are connected.

Cylinder Control Valve Installation

1. Hole Through Floor of Cab. If there is no holein floor of cab one will need to be cut with a 2" holesaw for the cables and wire harness to pas through.It will not require to cut the floor mat. See thejoystick section for cutting hole.

2. The controller assemblies will be bolted to-gether using a tie rod bolt. The control handles arethe same and the cables are the same, it is wherethey are connected to the control valve that makesa difference. (See Figure 1).

3. The "ON" / "OFF" Switch is bolted to theControl Handles. This is a good place but can bemounted somewhere else is desired. If Mountedsomewhere else keep in mind it must be acces-sible quickly by the operator in case of emergencyneeds. (See Figure 1)

4. The Arm Rest is bolted to the Control Handles.This has some options as to where it is bolted andcan be bent to adjust to individual preference.(See Figure 2).

5. Control Handle Stand is bolted to the floor ofthe Cab under the Floor Mat on the right hand side.There is a rubber plug in floor under floor mat here.Remove and/or cut the rubber plug to run thecables and wire harness through it. The openingaround cables through rubber plug can be sealedusing silicone sealer. Floor mat will lay back downaround cables and leave a small area of floor matopening. (See Figure 3)

6. Control Cables to Valve The control cableswill connect to Valve as shown in figure 3, To IDwhich cable is which have one person movehandle inside and mark which cable moves out-side. The cable connection procedure is shown.(See Figures 9 through 19).

Wire Harness: (Standard Mechanical Valve)

1. Starter Safety Switch Schematic, Mechanical Cable Operated Valve Type, NOT correctfor Optional Joystick (Electronic) Controls.

2. Figure 4 illustrates a common wire harness connection for A-Boom mowers with mechani-cal cable controls, If the Joystick Optional controls are used the Wiring will be different than shown.

3. Individual installations may vary and are dependent on the electrical and safety systemdesigns of the tractor to which the mower is mounted.

4. Consult the specific mounting instructions to determine the correct wire routing for eachspecific unit.

Common Problems:

1. The tractor won’t start: The mower on/off switch, if left in the “on” position will not allow the tractor to restart. Be sure to push the switch into the “off” position and account for all the tractorsafety interlocks to enable the tractor to start. Failure of the tractor starter safety lock system isnormally attributed to a failure of the mower on/off switch. Check continuity at the switch. Checkfor loose connections.

2. Cutter motor won’t start: Normal causes of this type of malfunction include failure of thepush/pull switch, failure of the solenoid coil, loose connections, loss of ground, or a blown fuse.If the mower won’t start, check continuity of the system with a test light to find an electrical problem.Problems may also exist in the cutter valve and other systems.

3. The problem may not be in the electrical system, but because there are so manyconnections that could be malfunctioning it is the best place to start checking. If the electricalconnections are OK, go on to the Tractor connections and/or the Tractor components to check forthe malfunction. Some times the service technician thinks the best way to eliminate the Mowerelectrical connection problem is to bypass them; this should never be done, eliminating the startersafety system is dangerous and hard on the Hydraulic System, The Hydraulic System will be tryingto start at a low RPM which is not good.

Standard Control Valve Operation:

1. This Control valve is the Standard 4 Spool that is remote cable Controlled, The 28 ft. modelused a 5 Spool valve with the 5 Th. Spool operating the Boom Extension. THIS SECTIONWILL NOT apply to the OPTIONAL ELECTRONIC JOYSTICK CONTROLS. This Sectionmostly shows the 4 Spool Valve, The 5 Spool Valve is mainly the same with the 5 Spooloperating the Hydraulic Door option on the Rotary head or the Boom Extension Cylinderon the 28-ft. Model. (See Figure 5 & 6)

"ON - OFF" Switch Installation



Cylinder Control Valve InstallationStandard Control Valve Operation:(continued)

2. The Standard Tandem (Dual) Pump System is Shown, there is a Single Pump System Optionavailable. The Single Pump only supplies the Hydraulics for the Cutter Head Motor and the TractorHydraulic System is used to supply the Boom Cylinder movements. The Schematic is very much thesame except the Cylinder Control Valve Hose connections are run to and from the tractor instead ofthe way they are shown in the Schematic on the next page. (See System Schematic drawings for PumpRepair Section)

3. The Control valve will not bolt on the topof the High Frame on the right hand side (SeeFigure 6). The Valve in Figure 6 does not showthe cables for the manual Control Cables con-nected, this is for illustration only. The ControlCables and Hoses are connected after the Valveis bolted to the mount plate. The Hoses must beconnected to the correct Port on the valve and tothe correct side to operate correctly (See Figure8). You should have a copy of the OperatorsManual and/ or Service manual for making thisinstallation. The Control cables for the manualcontrols will connect to the right side. This valveis bolted to weld on bracket between frame railand cab on LH side of tractor.

Cylinder Control Valve InstallationCylinder Hydraulic Control Circuit: (See Figure 7 & 8)1. Hydraulic power for the cylinder control circuit is taken from the second (smaller) stage of thehydraulic pump. Oil is supplied through hose 2 to the four (or five) spool control valve where it isdirected to the appropriate cylinder through the cylinder hoses. All of the cylinders are double acting.The system is protected from excessive pressure by an adjustable pressure relief valve located onthe inlet section of the valve. The pressure relief valve is factory set at 2000 PSI for the 17, 20, &23 foot booms and to 2500 PSI on the 28 foot booms. In addition, at least 3 individual cylinder circuitsare protected by a nonadjustable work port relief valve (See Specifications in the Service repairManual).2. One way restrictors are added to the valve sections such that the return flow from the cylinderswhen performing gravity aided function will slow the flow of return oil and allow for a more controllablemovement of the boom. (See the specifications for size of restriction and location in the Servicerepair Manual).3. Oil is returned from the valve through Return hose to the Cutter / Motor Control valve whereit then passes through Return hose into the return filter and into the tank.4. The valve utilized on the A-Boom mowers to facilitate the control of the boom movementfunctions is either a * 4 Spool or * 5 Spool, open center, sectional, manually operated valve. Themanual operation is performed with the use of normal directly attached valve handles or through theuse of cables and remote mechanical levers. * The 5 Spool has one more Spool than shown below,it is to operate the Boom Extension on the 28 ft; Boom or to operate a hydraulic activated Door onsome heads. The 5 th spool will be located between the Dipper and Tilt Spool shown in figure 3. (SeeFigure 15 later in this book)5. Although similar in appearance, each valve section is specifically designed to perform thespecified function for which it is assigned. The Valve is shipped assembled and should not bedisassembled during unit assembly.

REMOTE CABLE OPERATION AND INSTALLATION:

1. Remote operation of the boom movement control valve can be achieved with the use of cablesand remote actuator handles. The remote operation system is standard equipment on cab tractorunits and can be installed on ROPS tractors as well (See Figure 9). Four cable lengths are availableand should be ordered based on the length required to reach from the valve to the Operator’s locationwith out binding or kinking. Cable lengths are limited to 48,60,72 and 102 inches.

2. To install the cables to the valve, each valve section will require a cable installation kit (4 kitsfor a 4-spool valve, 5 kits for a 5-spool valve etc.). Each individual valve connection kit can be orderedusing part number 02971274. Figure 4 displays the contents of each kit. Cables are not includedin Cable Connection Kit.

Cylinder Hydraulic Control Circuit: (continued)

6. Hydraulic Cylinder Hoses. The Hoses for the Hydraulic Cylinders will be marked with bandsthat have the Part Numbers on them. These part numbers will vary with the size of the Boom Model.The 28 ft. model will have more hoses for the Boom Extend Function, the model with the HydraulicDoor on cutter head will have more hoses. To find which Hose you have you will need to consult theParts / Operators manual. When connecting the Hoses to The Valve use these numbers to connectthe correct hoses to the correct ports. It may be required that you do some tracing of hoses to findwhich hose is hooked to which end of a Cylinder. Listed below is a list of which end of HydraulicCylinder should be connected to which Port on valve. (See Figure 7 & 8)

Tilt ("B") ("A") StandardExtend / Door ("B") ("A") Only used with 28' Model or Optional Cutter Door)Dipper ("B") ("A") StandardLift ("A") ("B") StandardSwing ("A") ("B") Standard

You must consult the Parts Manual to determine correct Hoses used on the Model you have. Alsothe type Head used will make the Hose vary. There is a Electrical control valve Option, this will makea difference of which hose is connected where. If the hoses are connected to the wrong side of valveit should not damage any thing, it will mean that the control lever function will be reversed or maynot work at all because the Relief Valve is in the wrong direction of Oil Flow to operate.. Changingthe Hoses on the hose ports of the valve will change this.





3. Turn the Jam Nut and the Flange/Sleeve Assembly onto the threaded cableend to the entire length of the threads.Cables are not included in Valve connec-tion Kit. (See Figure 10).

4. Turn the cable eye Jam nut on the threadedcable end until it bottoms. Thread the Cable Eye ontothe cable end until it bottoms on the cable. Turn theeye to align with the spool end and secure the jam nutagainst the cable eye. (See Figure 11).

5. Slide the cable eye into the slot in the spool andalign the holes. Insert the connection pin and installthe retaining pin into the hole in the connecting pinand secure by bending both ears of the retaining pinback and around the connecting pin. (See Figure 12).

6. With the cable attached to the valve, turn theFlange/Sleeve Assembly back onto the threadedcable end until it is flush with the valve face. Whenturning on the assembly, make sure that the valvespool remains in the neutral position. (See Figure13).

7. Tighten the Jam Nut onto the Flange/SleeveAssembly to lock it into position. (See Figure 14)

8. Tighten the Flange into position using the twoallen head screws. Use a flat washer to support a lockwasher on each bolt. (See Figure 15)

9. Interference will occur between the Flange/SleeveAssembly and the casting of the Inlet Section on theValve Section next to the Inlet Section. To compen-sate, the provided shims should be placed on theFlange/Sleeve Assembly under the flange (See Fig-ure 16)

10. Each cable is controlled by the operator with the useof single axis control handle assemblies. A single controlhandle assembly is required to operate each individualvalve section. The control handle assemblies are orderedas P/N 02971243

Control Assembly - Controller End - In-stallation Procedure:

1. Each controller assembly comes fully assembled. Allrequired hardware etc. is included. The control cables arenot included with the control handles and should beordered separately. The Controller must face forward asshown or controls will be backward (See Figure 17).

2. To attach the cable, manipulate the controller handleso that the attachment nut is exposed as shown. Removethe lower most nut and screw from the controller housing.Thread the cable nut into the controller attachment nutand tighten. (See Figure 18).

3. Allow the controller handle to return to neutral.Slide the cable guide tube into the control housing andreinstall and tighten the housing screw.

4. Check the operation of the spool, cable andcontroller. Some adjustment at the valve end may berequired too ensure that the spool returns to neutral whenthe controller is in the neutral position. (See Figure 19).

5. The control lever assemblies utilizes a small springto make up for free play in the cable to valve connection.The control valve spool spring provides the centeringcapabilities of the controller and the valve spool. Lack ofcentering at the controller is normally attributed topoor adjustment at the valve to cable connection orbinding of the cables due to poor routing.

6. The control lever assemblies will bolt together toform a group of handles, there will be 4 for the 4 spoolvalve and 5 for the 5 spool valve. Also the "ON" and "OFF"Switch will bolt to the Handles (See Figure 1 & 2)

Installing Wire HarnessTo Valve:

1. Wire Harness From Cab to Front. The wireharness runs out the bottom of the Cab on the righthand side. Run harness along under RH cab ofTractor to the control valve (See Figure 12). Notethe wire harness runs bottom of cab and near theexhaust from the Tractor to the Stack Valve to thefront of the tractor. Make certain to tie the Harnessor Hoses to the Tractor for protection.

2. Gaskets on Valve Terminals. There are 5wire terminals on Valve, A Gasket will have toinstalled on each one. These gaskets will only fitone way, there are 4 slots in gasket. 1 Slot is widerthan the other 3, align these slots with correctterminal on Valve. (See Figure 13 & 14). TheseGaskets must be used. Note; the gasket are shownlaying on a tank only as a back ground, they mustbe installed on the valve before wire terminals areconnected. In the Illustration in Figure 14 the Plugsare no visible because they are under the hoses onthe bottom.

3. Connect Lock Valve connections. There isa lock valve use on the head Tilt function, thiselectric locking device is located at the valve on tilthose connections, this connection needs to bemade now.

4. Wire Harness Terminal Identification. TheWire Harness Terminal Plugs are marked in writingon the plug. Swing, Lift, Dipper, Tilt and Doorterminal plugs (5 Total). The Valve terminals are inthis same order starting at the bottom and comingup on the valve. You will need to have a shorthandle Phillips screwdriver for this. (See Figure26).

5. Wire Harness Terminal Installation. Youwill need to feed wire harness under the fitting ofhoses to valve. (See Figure 14) lay the Plugs outin the Order they are to be installed starting at thefar end terminal.

Mower Head Installation - OptionalAttaching Ditcher Head:

WARNING Escaping fluid under pressure can penetrate the skin causing serious in-jury. Relieve pressure before unhooking hydraulic or other lines. Tighten all connectionsbefore applying pressure. Keep hands and body away from pinholes and nozzles whicheject fluids under high pressure. Use a piece of cardboard to search for leaks. If ANYfluid under pressure is injected into the skin, it must be surgically removed within a fewhours by a doctor familiar with this type injury or gangrene may result.

1. With a forklift or hoist, lower the Boom Weldment down in the Ditcher Head. Align theBoom Weldment with the Ditcher Head Hitch Post together. Insert special pins p/n 02958929 intoBoom Weldment and Hitch Post. Attach with washer P/N 00749185 and roll pin P/N 00610600.NOTE: Additional support may be needed at the end of the Boom to aid in installation. (SeeFigure 5).

2. Attach Hydraulic Hoses as illustrated (See Figure 69). Tighten all Hydraulic Fittings. Caremust be taken when tightening Hydraulic Fittings. Over tightening can cause the fittings to crackand require replacement. Use recommended hose end torque values found in chart in operatorsmanual..

3. The motor for the Ditcher will operate in both directions. It is important to plumb the motorso that it rotates to deposit the spoil properly. The direction of rotation can be observed by stand-ing behind the Ditcher Head, beside the right rear tire. If the Ditcher rotates 'clockwise' it isplumbed for forward rotation and the spoil will be deposited away from the tractor. If the Ditcher isthe reverse design then the proper rotation is counterclockwise when observed from the rear. DoNot try to reverse Ditcher from Rotation it was designed for, it will not work. The Forward andreverse Rotation Models do not use the same Blade Assembly.

4. Note: The two hoses (P/N 02961054) connecting the main boom to dipper arm are used toconnect the Ditcher motor. The 90 degree fittings attach to the fittings on the main boom and thestraight fittings attach to the 90 degree fittings on the hydraulic motor. See Figure 69 below.

Fill Hydraulic Tank

Section 10



Fill Hydraulic TankFill Hydraulic Tank with Oil:

1. DO NOT START TRACTOR until you havefilled Hydraulic Oil Tank to a level as shown inSight Glass gauge and fill the Suction Hose toPump with Oil.

2. Remove Filler Cap. Remove Filler cap onlywhen ready to fill hydraulic Tank with Oil. Do Not leavethe Cap off and the system Open, always keep systemclosed when possible. Avoid any oil contamination. (SeeFigure 1)

3. Avoid Hydraulic Contamination by filtering theHydraulic Oil while filling the Hydraulic Tank. Filter bug-gies or carts are commercially available for Hydraulicsystem cleanup and Oil transfer. These consist of highcapacity filter, a Circulating Pump, a Drive Motor andhoses for connecting to the units hydraulic system.When adding Oil always use Clean new Oil from a sealedcontainer, If you suspect the Oil of being contaminateddon't use it. (See Figure 2 & 3). It is best to always use afilter system when adding even new oil.

4. When adding Oil in the field keeping it clean iscritical, do not use dirty funnels or hoses. Do Not openHydraulic tank or any containers unless the openingshave been cleaned first. The outside of the containersmust be clean. If a windy dusty day do not fill and allowdirt to blow into oil. Always add Oil using a pump systemwith at least a 10 Micron filter system. (See Figure 4)

Fill Hydraulic Tank with Oil:

5. Fill Tank. Fill the Hydraulic Tank (See Figure4) Fill tank till the Oil is visible in the sight Gauge (SeeFigure 5 & 8). This will fill tank for the start but it willhave to filled again later. Read Step 6 a must.

6. Fill Suction Hose with Oil.This is an important step that must be

done. Remove the Suction Hose at the Tank (SeeFigure 6) and fill the hose with clean oil, THIS IS AMUST DO. The Suction Hose must be filled with Oil toprevent Dry start up of Pump. Dry start up of PUMP willdamage the Pump. After filling suction Hose reinstallit and tighten down Hose Clamp. (See Figure 7)

Hydraulic Start-UpProcedures

Section 11



Start-up Instructions:1. Read all safety instructions. Decals on the A-Boom warn you of particular and multiple Haz-ards. Many decals are attached close to part of the A-Boom where there is a possible hazard. Readand make sure you understand the safety messages before you operate the A-Boom.Keep alldecals clean and readable. Replace lost or damaged decals.2. Before operating, read all the safety and operating instructions in the Operator's Manuals forboth the tractor and mower.3. When the hydraulic tank has been filled, The Pump Suction Hose filled with Hydraulic Oil andthe mower unit (Head) properly assembled, the unit should be started up. NOTE: Make sure that nomaterials, tools, or jacks have been left under the mower head. Make sure the front and rear of themower are properly guarded to prevent any foreign objects from being thrown by the mower. Allother workers should be kept a safe distance from the unit before the mower is started.4. Start the tractor and idle at a slow engine speed until oil is being pumped. Check for any leaks,this is easiest with an assistant watching for leaks. Do not run if Oil is leaking.5. Bleed the air out of all hydraulic cylinders one at a time by extending them to their full length. DONOT SWING THE BOOM till last and you have gone to the Rest Stop and Support Section forinstructions.6. Engage the Cutter Control Valve at low engine rpm and run the mower slowly for a short perioduntil all air is removed from the hoses. Keep all persons WELL CLEAR of mower since Blades canTHROW OBJECTS with great velocity for a considerable distance! KEEP CLEAR!7. Run the mower at a low tractor engine speed until the mower Hydraulic System gets the Airout off it. Operate at an engine speed that keeps the filter restriction gauge reading in the "GreenZone". With the hydraulic warm, bring the tractor speed up to normal operating speed. If the filtergauge reads in the red zone, stop the unit, release all hydraulic oil pressure, and Check the filterelement in the tank mounted filter or any Hose that may be kinked. Restart the tractor and mowerunit and again check the filter gauge (oil must still be hot).8. If the filter gauge reads in the red when first started and does not drop as oil warms, thensomething is wrong, contaminants have been introduced into the hydraulic system or some thingconnected wrong. You may need to repeat previous steps again until the gauge reads in the green.9. Check the fluid level in the Hydraulic Tank and add oil if required. As the air has been forced outof the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the oil level. The HydraulicOil must be at least at the level of the Sight Gauge on the side of the Tank.10. Basic trouble shooting guide for first start up. A. Electrical solenoid valve does not work - check wiring, possible faulty switch, possible faultysolenoid. B. Pump is making noise - check for obstruction in suction hose and tank suction assembly,check alignment of pump driveshaft. C. Cylinders will not raise - hoses from cylinder incorrectly connected to valve bank, pump notsuppling oil. D. Cylinder rises slowly - hoses from cylinder incorrectly connected to valve bank, work portreliefs on valve bank set too low - replace as required. E. Filter reads in red - viscosity of oil too high - wait until oil heats up before checking filtergauge. If gauge reads in red even after unit is hot, then the filter must be replaced.

Hydraulic Start-Up Procedures



Post-Assembly Check List:

1. Is oil level in the tank even with the sight gauge on the tank?

2. Has the proper oil been used in the system? Proper oil is Universal Tractor Hydraulic.

3. Does Boom machine movement match operation decal - Swing, Lift, Dipper, Tilt?

4. Is control valve free and does it not stick?

5. Are all hoses tight and do not leak?

6. Are all decals in place? See Safety Section in Manual for decal description andplacement.

7. Does tractor pass Alamo Group Mower Stability Test?

8. Have all grease points been adequately greased?

9. Are all bolts tight?

10. Have all hoses been properly routed so that hoses do not kink or bend when boom is articulated through all motions?

11. Does starter lockout device work correctly on machine? Tractor should not start if mower switch is on.

12. Is swing cylinder pinned in correct hole? On rear-swing type machine cylinder shouldbe pinned to outside hole. On front-swing type machine cylinder should be pinned in inside hole.

13. Is machine equipped with proper operator protection? Must have cage or cage panels.

14. Does mower operate when on/off switch is on? Stop when switch is off?

15. Is head rotation correct? On rotary heads (looking from the top of the deck) rotationshould be clockwise so that debris will be thrown away from the tractor. On flails,rotation can be forward or reverse, but forward rotation is standard.

16. If furnishing a square head, are spindle housing bolts tight? Is spindle assembly tight?Are bolts that hold blade bar to spindle tight?

17. Does head operate smoothly at normal operating speed? Head should not vibrate excessively.

Restrictions:1. Must be ordered with a high frame due to high opening hood design.2. Electrohydraulic mt kit includes a seat-mounted joystick as shown in Figure 3 below.Other seat styles may require modification of this bracket at the dealer/customer’s expense.3. If an optional wheel weight is desired, the tractor must be equipped with a flanged rear rimas shown in Figure 4 for proper wheel weight mounting. If the tractor is equipped with a disc-type rim as shown in Figure 5, then the optional wheel weight adapter must be ordered.4. This mount kit is not designed for tractors equipped with a SuperSteerTM front axle orTerraGlideTM front suspension system. Furthermore, it is not recommended for the TM175 & 190models due to their front bolster variance.5. Frame location is very critical when mounting these units. Always make sure that the airfilter is accessible before welding everything in place. Some modification of the mounting tubemay benecessary in order to complete this task. Such modifications are considered part of themounting expense and will not be covered under warranty.6. These mount kits were developed on a Cab/2wd TM120. Every effort has been made toprovide adequate tire clearance for tractors equipped with mechanical 4wd. Adjustment of thetread setting and steering stop may be necessary. In addition, an articulation block may berequired, but has not been included at this time. Finally, the hoses in these kits were sized fora 2wd as well. We are hoping that little to no alteration will be necessary for the 4wd application.However, until a 4wd model is mounted for inspection at our Seguin facility, the dealer / customeris responsible for all necessary modifications as mentioned above.7. For tractors equipped with a 28' boom, add a minimum 1400# wheel weight in addition tofilling the left rear tire with calcium chloride. Also, depending on the size of the head, it may beadvisable to add one of the optional weight kits as well.8. All components of this mount kit except the driveline should be interchangeable withCase-IH MXM120-155 tractor models.

Notice: Mounting restrictions may change as designs of tractor model changes and/or design of the A-boom is updated orchanged. Listing in this assembly manual is current as of the print date.
