TWIN Air technique

General information

With TWIN air assistance energy is added to the spray droplets toimprove control with the spray liquid. The main purpose of theTWIN angling system is to counteract for the negative influencewhich wind direction and driving speed have on the quality ofthe spray job. Further the “co-angling” af air and liquid can help“opening” dense crops for better penetration.

This way TWIN makes it possible to:

• carry the spray droplets safely to the target and increase plant

deposit.

• minimize off-target deposit due to wind drift or loss on the

ground.

• open the crop and obtain good penetration even with a lowvolume rate.

• ensure a high coverage.

The TWIN FORCE air system can be set at any angle from 40° forward to 30° back (defined by the air stream). The

fan speed is infinitely variable and can produce from 0 to 35 m/s (78 mph) air speed at the air outlet. This equals

from 0 to 2000 m3 air/m boom/hour (3.872 CFM/A boom/hour).

4.5

Adjusting the air assistance

TWIN Air technique

The air speed and angling must always be adjusted individually for each spray job and the given weather conditi-

ons. It is always a good idea to get used to a new sprayer out in a field with only water in the tank, on this occasion

the following routine for air adjustment should be practised:

1. Start with the air vertical

2. Set the air speed: See section “Setting of air speed, rules of thumb”

3. Find the best angling: See section “Angling of air and liquid, rules of thumb”

4. Readjust the air: See section “Setting of air speed, rules of thumb”

ATTENTION! Fine tuning of air speed and angling will often be necessary all through the spraying job.

ATTENTION! It is easiest to find the best air setting to reduce drift when the sun is low and behind the boom(backlight). These conditions make the drift more visible.

Setting of air speed, rules of thumb

Step 1: Find the range of air speeds that can control drift

1.Start with the air setting at zero and keep increasing the air speed just to the point where you can see that the

drift cloud is minimised - note minimum setting.

2.Then increase the air speed until you see drift again - note maximum setting.

3.Now you know the range of air speeds that can be used with minimum drift.

Bare ground / low crop: The range of air speeds is usually very small.

Taller crop: The taller the crop the wider the range of air speeds that can reduce drift. At higher wind

speeds: More air is needed on the sprayer and it is advisable to drive more slowly and use minimum

boom height (40 cm)/(16 in).

Too high air speed over bare ground/low crop can cause reflection of the spray liquid and leave dust on the leaves,

which can again reduce the effect of the plant protection product.

Step 2: Set the optimal air speed within possible the range mentions above.

Air speed recommendations:

Bare ground / low crop: Use maximum air within the possible range.

Taller crop: Deeper crop penetration requires more air on the sprayer (if you are in doubt check with water sensitive

paper).

Forward speed: Higher forward speeds require more air on the sprayer.

Volume rate: Lower volume rates require more air assistance to prevent drift.


4.6

Angling of air and liquid, rules of thumb

To control wind drift the influence of wind speed and wind direction as well as the horizontal air current aroundthe boom due to forward speed must be minimised. Because it is a sum of two forces with variable direction andsize that we have to counteract for, the following can only be very rough guidelines.

Wind direction:

Head wind: Angle forward.

Down wind: Angle back (if the forward speed is higher than the wind speed: angle forward).

Side wind/no wind: Angle vertical or back. Only high forward speeds may require forward angling.

Crop condition:

Bare ground/low vegetation: Low air speed and angling back will often be the best setting to avoid reflection ofspray liquid.

Dense crop: The angling feature is ideal to help opening the canopy and improve penetration. If you follow thecrop movement as you are varying the angling you will find that at certain settings the crop will open more forpenetration.

If wind speed, wind direction or for some reason forward speed changes during spraying the optimum angling islikely to change too. Be aware that with certain combinations of air speed and angling you can “close” or flatten thecrop and make penetration impossible - follow the crop movement intensively especially when setting the air assi-stance and keep an eye on the crop all through the application.

• It is most important that the sprayer operator is familiar with the above rules of thumb before using the TWINsprayer.

• All volume rates, pressures and air adjustments stated in the following tables are, of course, guiding. Special condi-tions regarding climate, crop quality, spraying time and applied chemical can change the procedure. The tables are

showing practice in northern Europe, and conditions may be very different in other countries. If you want somelocal advice you are very welcome to contact the TWIN application expert at the HARDI importer or daughter com-pany in your country.

• The volume rate can generally be reduced to half of what is applied with a conventional sprayer, but with a mini-mum of 50-60 l/ha at 7-8 km/h (5.5-6.5 GPA at 4.5-5 mph. Exceptions are of course liquid fertiliser and herbicideswhose

selectivity is based large droplets that will only stick to the weeds.

• Low drift nozzles can also be fitted on a TWIN sprayer and help reduce drift even further.

• If there is a detailed spraying instruction on the chemical label regarding drop size, spray pressure, spray volumerate etc. this should be followed. Enclose 1 bag of water sensitive paper and instruction of how to use with all TWINsprayers.

Water sensitive paper

USE WATER SENSITIVE PAPER TO HELP FIND THE BEST AIR SETTING.

Some time spent in different types of crops with clean water in the tank and some water sensitive paper

will be valuable experience for the future work with your TWIN sprayer. The paper can be cut into smal-

ler pieces (to simulate the target) and fixed with double sided tape at relevant places in the crop. Then

spray with pure water and check the blue spots (droplets) on the paper. This way you can test different

spraying techniques. Water sensitive paper is available

at your local HARDI dealer, part No. 893211.

Damping adjustment

HAZ Boom

When altered the guide rod setting in “Suspension perform-

ance adjustment” then it is possible to adjust more accurate-

ly in the field. This is done with the electrical damping con-

trol, which is situated at the centre section of the boom.

When the throttle valve (A) is screwed all the way in, follow-

ed by three reverse turns out (factory setting), the boom

suspension will react immediately, and the boom will move

independently of the trailer or tractor.

To obtain more damping: Throttle valve (A) must be screwed inward.

To obtain less damping: Throttle valve (A) must be screwed

outward.

Boom folding speed adjustment

ATTENTION! The system must not be pressurized during

adjustment.

There are restrictors for adjusting of boom folding speed -one per each boom wing. The restrictor are located near thebig pendulum damping cylinder.

The adjusting screw are adjusted as follows

To decrease folding speed: Loosen counternut (arrowed)and to adjust folding speed valve (arrowed) must be screw-ed inward. Lock counternut again.

To increase folding speed: Loosen counternut (arrowed) andto adjust folding speed valve (arrowed) must be screwedoutwards. Lock counternut again.

Forward movement and braking in AUTOMOTIVE mode

In ROAD mode, the engine speed is associated to the forward speed. The transmission ration is established by

managing the engine speed, the hydraulic pump capacity and the hydraulic motors capacity.

The ROAD mode simplifies the driving experience, requiring only one control, and reduces fuel consumption signifi-

cantly.

The ROAD mode is active when the speed selector is atposition (1).

When the the grip lever is at neutral position, the engine idles.

As soon as you push the forward gear lever, the vehicle starts

moving and the engine speed increases according to the posi-

tion of the forward gear lever.

WARNING! In vehicles fitted with the boom retraction device, make sure that the boom is fully retracted befo-

re moving the vehicle. Otherwise, the vehicle will not move.

For further details, refer to the chapter ‘Boom retraction’.

The vehicle braking is achieved by sliding the forward gear lever

to neutral position. In this case, braking will be much more effi-

cient if the the grip lever is quickly brought back to neutral posi-

tion, and the engine speed turns to idle.

For vehicles fitted with the dynamic brakes option, deceleration

is proportional to the pressure exercised on the brake pedal.

1. ROAD mode

2. WORK Mode

To move from WORK mode (2) to ROAD mode (1), slide the forward gear lever to neutral position, to activate

the ROAD mode.

WARNING! If pressure on the brake pedal is maintained until the vehicle is completely stopped, you must

bring the forward gear lever to neutral position, then press it again, to start moving.

On the other hand, if you press the brake pedal punctually, the vehicle slows down. Once it is released,the vehicle regains its initial speed, according to the position of the forward gear lever.

To optimize dynamic braking efficiency, the device controls the automatic capacity change of hydraulic

motors.

For vehicles fitted with the dynamic brakes option, deceleration

is proportional to the pressure exercised on the brake pedal (1).

Forward movement and braking in WORK mode

In WORK mode, the engine speed remains constant. The forward movement depends only on the inclina-

tion of the forward gear lever.

A device allows to limit the forward speed, while the forward gear lever is tilted to its maximum point

towards the front.

1. TURTLE mode: the capacity of front and rear hydraulic motors

is maximum, to transmit a higher engine torque to the 4 wheels,

with a lower forward speed (about 20 km/h)

2. UPHILL mode: the capacity of rear hydraulic motors is maxi-

mum, to transmit a higher engine torque.

3. DOWNHILL mode: the capacity of front hydraulic motors is

maximum, to transmit a higher engine torque.

In mode (1), Easy Drive automatically controls the capacity change of loaded hydraulic motors, depending on the

forward speed.

In mode (2), the torque transmitted is higher on the rear wheels than on the front wheels, which improves the grip

of rear wheels in slopes.

In mode (3), the torque transmitted is higher on the front wheels than on the rear wheels, which improves the grip

of rear wheels when descending slopes.

IMPORTANT: To change from AUTOMOTIVE mode (‘hare’ position) to WORK mode, the AUTOMOTIVE mode

deactivates. In this case, you may use the speed limit function.

WARNING! In WORK mode, transmission requires a minimum engine speed of 1600 rpm before movingforward, in order to ensure maximum traction and braking output.

IMPORTANT: In WORK mode, you may turn the speed selector to one of the modes (1), (2) or (3), without stop-

ping the engine.

The speed limiter is active only in WORK mode, i.e. when the

speed selector is in positions (1), (2) or (3).

The advantage of this device is that it maintains a constant for-

ward speed, when the forward gear lever is in the maximum

forward position (4).

5 - Operation

To use the speed limiter:

1. Turn the button to position 0.

2. Slide the forward gear lever to maximum position (4), the

vehicle remains stationary, or moves at a very slow speed.

3. Turn the speed limiter to obtain the desired forward speed.

IMPORTANT: To deactivate the speed limit function, adjust the speed limiter at position 10 to obtain maximum

speed in WORK mode.

IMPORTANT: The speed limiter is not effective in reverse.

Parking brake

The parking brake works by mechanical action. It acts on the discs located in the hydraulic motors of front and rear

wheels. A spring maintains the discs and activates the parking brake in the absence of pressure in the braking cir-

cuit.

The parking brake is used to keep the vehicle stopped.

When the parking brake is activated, and you push the forward

gear lever, the vehicle will not move.

In order to move:

1. Release the parking brake by turning the speed selector.

2. Push the forward gear lever to move forward.

IMPORTANT: When the parking brake is engaged, the ladder goes down automatically.

WARNING! The parking brake is very powerful!

Do not use it while the sprayer is moving, except in cases of extreme emergency.

IMPORTANT: In case of emergency stop, mechanical brakes are engaged by acting on the speed selector, and if

the vehicle is fitted with dynamic brakes, these also act on the transmission pump.

Agitation before spraying operations

Before the spraying operations, or if the application has been

interrupted for some time, an important sedimentation can occur

in the product used. It is essential to put the spray mixture back

in suspension in the main tank. The principle consists of circula-

ting the spray mixture through a perforated pipe located in the

tank bottom.

1. Turn the handle at the suction SmartValve towards “suction

from main tank”, and the pressure SmartValve should be turned

toward “Spraying”. Turn the agitation valve on “Agitation”

2. Engage the spraying pump at least 10 minutes to make the

spray mixture homogenous.

ATTENTION! If there is not time enough to fill all chemicals into the ChemFiller before main tank is full, then it

is possible to slow down filling proces by partly closing the External Filling Device valve.

DANGER! Do not press lever unless the multi-hole nozzle is covered by a container to avoid spray liquid hit-ting the operator.

General information

In order to derive full benefit from the sprayer for many years the following service and maintenance program sho-

uld be followed.

Cleaning

ATTENTION! Always read the individual paragraphs. Read instructions for service/maintenance jobs carefully

before starting on the job. If any portion remains unclear or requires facilities which are not available, then for

safety reasons please leave the job to your HARDI dealer’s workshop.

ATTENTION!

Clean sprayers are safe sprayers.

Clean sprayers are ready for action.

Clean sprayers cannot be damaged by pesticides and their solvents.

Guidelines

1. Read the whole chemical label. Take note of any particular instructions regarding recommended protective clot-

hing, deactivating agents, etc. Read the detergent and deactivating agent labels. If cleaning procedures are given,

follow them closely.

2. Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods,

etc. Contact the appropriate department, e.g. Dept. of Agriculture.

3. Pesticide washings can usually be sprayed out on a soakaway. This is an area of ground that is not used for crop-

ping. You must avoid see page or run off of residue into streams, water courses, ditches, wells, springs, etc. The was-

hings from the cleaning area must not enter sewers. Drainage must lead to an approved soakaway.

4. Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining

spray liquid.

5. It is good practice to clean the sprayer immediately after use and thereby rendering the sprayer safe and ready

for the next pesticide application. This also prolongs the life of the components.

6. It is sometimes necessary to leave spray liquid in the tank for short periods, e.g. overnight, or until the weather

becomes suitable for spraying again. Unauthorised persons and animals must not have access to the sprayer under

these circumstances. 7. If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer

before and after use with a suitable rust inhibitor.

Cleaning and maintenance of filters

Clean filters ensure :

• Sprayer components such as valves, diaphragms and operating unit are not hindered or damaged

during operation.

• Nozzle blockages do not occur whilst spraying.

• Long life of the pump. A blocked suction filter will result in pump cavitation. The main filter protecting

sprayer components is the suction filter at the top of the tank. Check it regularly.

Use of rinsing tank and rinsing nozzles

The incorporated rinsing tank can be used for two different purposes.

A. In-field diluting of remaining spray liquid residue in the spraying circuit for spraying the liquid in the field, before

cleaning the sprayer. This cleaning procedure is divided in three main steps:

Cleaning of the liquid system:

1. Empty the sprayer as much as possible. Close the AgitationValve (no agitation) and spray till air comes out of all

nozzles.

2. Turn Suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Main tank”.

3. Engage and set the pump at approximately 300 r.p.m.

4. When 1/3 of content in rinsing tank (~150 litres) are used, turn Suction SmartValve towards “Main tank” and ope-

rate all valves on the pressure side of the system in the following order, so all hoses and components are rinsed:

Open chemical incorporator suction valve, open ChemFiller Vortex nozzle and close it again when clean water

comes out of nozzles. Close ChemFiller lid and squeeze the Chemical Container Cleaning handle to clean this devi-

ce. Open ChemFiller lid again and assure that ChemFiller is empty. When empty then close the ChemFiller suction

valve again.

5. Turn the suction SmartValve towards “Main tank” and pressure SmartValve towards “Spraying” and spray liquid in

the field you have just sprayed.

Cleaning of Main tank:

6. Turn the suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Internal Tank Cleaning”.

7. When another 1/6 of content in rinsing tank (~75 litres) are used, then turn suction SmartValve towards “suction

from Main tank”.

8. Turn pressure SmartValve towards “Spraying” and spray liquid in the field you have just sprayed.

9. Repeat point 6 - 8 one more time.

Outwards cleaning:

10. Turn suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Internal Tank Cleaning”.

11. When another 1/3 of content in rinsing tank (~150 litres) are used, then turn suction SmartValve towards “Main

tank”.

12. Turn pressure SmartValve towards “External Cleaning Device” and wash the sprayer with the cleaning device

located on sprayers right side.

13. Disengage pump again.

B. Rinsing the pump, operating unit, spray lines, etc. in case of stop in spraying before main tank is empty (e.g.

beginning rain etc.).

Cleaning of the liquid system:

1. Turn Suction SmartValve towards “Rinsing tank”. (Keep pressure SmartValve in “Spraying”-position).

2. Close AgitationValve (no agitation).

3. Engage the pump and spray water from rinsing tank in the field until all nozzle tubes/nozzles are flushed with

clean water.

4. Disengage pump again.

5 - Operation

5.26

ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manually

with a brush afterwards, especially if crops sensitive to the chemical just sprayed are going to be sprayed

afterwards!

ATTENTION! It is advisable to increase the forward speed (double if possible) and reduce the pressure to

1.5 bar (20 psi).

ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.

ATTENTION! If the sprayer is cleaned with a high pressure cleaner lubrication of the entire machine is recom-

mended.

5 - Operation

5.27

Inevitably a quantity of spray liquid will remain in the system. It cannot be sprayed properly on the crop, as thepump takes in air when the tank is about to be empty.

This Technical Residue is defined as the remaining liquid quantity in the system as the first clear pressure drop onthe pressure gauge is read.

The dilutable residue must be diluted 10 times with clean water and sprayed to the crop just sprayed before clea-ning the sprayer.

Technical residue

Using the drain valve

The drain valve is located and operated from the platform

just beside the main tank lid. Pull the string to open the

drain valve. The valve is spring-loaded, but can be kept

open by pulling the string upwards in the V-shaped slit. To

release, pull the string downward and the valve will close

automatically.

If draining residues, e.g. liquid fertilizer into a reservoir, a

snapcoupler with hose can rapidly be connected to the

drain valve and the liquid safely drained.

Transfer

It is possible to drain to an external tank. This is done the

following way:

1. Connect a hose from an external tank to the suction

quick coupler on the sprayer (pressure).

2. Turn the Pressure SmartValve towards “External tank”.

3. Turn the Suction SmartValve towards “Suction from main

tank”.

4. Engage the P.T.O to start the pump.

5 - Operation

5.28

Outwards cleaning - Use of External Cleaning Device(optional equipment)

Use the External Cleaning Device to wash everything on the

outwards side of the sprayer. This prevents contamination of

storage place etc. and let the sprayer last for a longer life.

When the External Cleaning Device is going to be used, then

open the cover on sprayers right side closest to the handbrake.

Cleaning gun is located on the innerside of the cover.

1. Un-roll the hose from the reel.

2. Engage pump at approximately 300 r.p.m.

3. Turn suction SmartValve towards “Suction from Main tank” and

pressure SmartValve towards “Main tank”.

4. Turn agitation valve towards “External Cleaning Device” and

clean sprayer.

5. After cleaning then close the agitation valve again.

6. Roll the hose to the reel again and close cover

ATTENTION ! If the safety valve of spraying circuit is ope-

ned, the revolution of spraying pump must be reduced to

prevent that the clean water does not return in the tank .

Winter storage

Storage procedure

When the application season is concluded, allocate some time to your sprayer. Chemical product waste damages

the equipment components. To preserve them and assure their long life, follow this procedure.

1. Clean the sprayer completely, inside and outside, as indicated in the chapter “Cleaning the sprayer”. Make sure

that all pipes, valves, and other components have been washed with detergent and flushed with clean water so as

to remove all residues.

2. Replace damaged joints and repair leakages.

3. Drain the equipment completely and allow the pump to run for a few minutes. Operate the valves, handles and

levers manually in order to drain the spraying circuit to the maximum. Allow the pump to run until there is only air

coming out of the nozzles. Remember to drain the flushing tank in the same manner.

4. Pour approximately 50 lt. of anti-freeze solution in the tank (1/3 anti-freeze + 2/3 water).

5. Run the pump and operate all valves so that the solution is distributed throughout the circuit.

Open all the distributors until the solution arrives at the nozzles. The anti-freeze solution also prevents joints, rings

and membranes from drying. Do not use a liquid fertilizer instead of the anti-freeze.

6. Lubricate all lubrication points as specified in the chapter “Lubrication” without taking the lubrication frequencies

into consideration.

7. When the equipment is dry, remove all traces of rust and touch up the paint, if necessary.

8. Drain, dismantle and put the pressure gauges away from frost in vertical position.

9. Apply a thin coat of anti-corrosion oil (Shell ENSIS FLUID, Castrol RUSTILLO, or similar) on all metallic parts, avoi-

ding rubber parts, pipes and tires.

10. Fold the boom in travel position and bring down the pressure of all hydraulic functions.

11. Arrange the electric plugs and sockets in a plastic bag to protect them from humidity and dust. Spray them

with an anti-corrosion pump.

12. Remove the tractor cabin control boxes and arrange them away from frost so that they are dry and clean. Spray

plugs against corrosion.

13. Dry hydraulic sockets and put the caps on.

14. Lubricate all cylinder rods that are not completely retracted, in order to protect them from corrosion.

15. Isolate the wheels from the ground in order to protect them from humidity, and prevent the tires from bending

out of shape. You may apply a black polish on tires to protect the rubber.

16. Drain the pneumatic brakes air tank to prevent condensation.

17. You may cover the sprayer with canvas sheet to protect it from dust. Always maintain the air circulation in order

to avoid condensation.

6 - Maintenance

6.36

Preparing the sprayer after winter

After the storage period, prepare the equipment for treatments as follows:

1. Remove the canvas sheet - if applicable.

2. Check the tires pressure.

3. Clean the grease from cylinder rods.

4. Put back the pressure gauges. Use Teflon tape to fill gaps.

5. Couple the sprayer to the tractor and make the electric and hydraulic connections.

6. Check all electrical and hydraulic functions.

7. Drain the rest of anti-freeze solution from the tank.

8. Flush the spraying circuit with clean water.

9. Fill the tank with clean water and check all functions.

10. Check the brakes. Remember that their power is reduced to nothing as a result of rust built up in the drums. At

first, do not brake suddenly.

General information

Operation Incidents

Operation incidents are frequently due to the same reasons:

1. A suction leakage reduces the pump pressure and may interrupt suction completely.

2. A clogged suction filter may damage suction or interrupt and prevent the pump from running normally.

3. Clogged nozzles increase pressure in the pressure gauge but reduce the boom flow.

4. Impurities sucked by the pump may prevent the valves from closing correctly, thus reducing the pump flow.

5. A bad reassembly of the pump elements, especially diaphragm heads, causes air intakes or leaks and reduces thepump flow.

6. Rusted or dirty hydraulic components cause bad connections and early wears.

7. A badly charged or faulty battery

To prevent these consequences, ALWAYS check:

1. Suction and pressure filters, as well as nozzles, are clean.

2. Pipes, especially suction pipes, are intact: no leaks, folds or binding occur.

3. Rings and joints are in their place and in good condition.

4. The pressure gauge works correctly -dosage accuracy depends on it.

5. Regulation works correctly. Control the distributors with clean water.

6. Hydraulic components are clean.

7. The good condition of the battery and its couplings
