Power Plate Specifications
Attachment Conventional skid loader quick-attach
3-Point Hitch Category-1
Construction Heavy-duty ¼” plate steel
Finish Polyurethane paint with epoxy primer
Weight 280 lbs.
5.4 cu. in. For standard skid loader systems with 14 - 18 gpm
Hydraulic Motor 7.1 cu. in. For high-flow skid loader systems
with 19 - 28 gpm
PTO Horsepower
Horsepower (hp) delivered to the Power Plate PTO is determined by the following formula: hp = gpm x psi / 1714
Limitations The Power Plate is not recommended for use with brush cutters having a single blade greater than 50” in diameter.
perate conventional PTO-powered implements: The Power Plate is a unique attachment that can be used to operate conventional PTO-
owered implements that have a Category-1 3-Point hitch. Care should be taken, however, not to se implements that excessively twist the structure of the Power Plate, e.g.: brush cutters with ingle blades greater that 50” in diameter.
asy attachment to standard skid loaders: The Power Plate is attached to a standard skid loader with the “quick-attach” mechanism
here the bucket would normally be located. Compatible skid loaders include: Bobcat, New olland, John Deere, and Case IH, as well as several other brands.
vailable horsepower:
The horsepower generated by the hydraulic motor is dependent upon the capacity of the kid loader. Hydraulic horsepower (hp) can be determined using the following formula:
hp (horsepower) = gpm (gallons per minute) x psi (pounds per sqare inch) / 1714.
hus, if a skid loader has 18 gpm flow and 2500 psi, the Power Plate would be capable of enerating approximately 26 hp.

SAFETY WARNING!
Altering this equipment in any manner which adversely affects its operation, performance, durability, or use will void the warranty and may cause hazardous conditions. EQUIPMENT & CONTROLS • READ AND UNDERSTAND THE
OWNER’S MANUAL BEFORE OPERATION.
• Know the location and function of all
controls and how to stop this equipment quickly in an emergency before you operate the equipment.
REE POINT HITCH ARMS: Used to cure implements to the skid loader achment.
• Keep the equipment and attachments in good operating condition. NTER LINK: Used to secure implements
the skid loader attachment and adjust to el position.
• Keep all guards and shields in place
during operation. DRAULIC MOTOR: Powers implements t are attached to the unit.
• Replace all worn, damaged, unusable, missing, or lost safety shields before operating the equipment. DRAULIC HOSES: Connect to the remote
draulics of the skid loader in order to nsfer power to the hydraulic motor.
• Keep nuts, bolts, and screws tight to help ensure the safe operation of equipment. ABILIZER BAR: Secures to right three
int hitch arm and keeps implements from inging from side to side.
• Use genuine factory parts or parts with
equivalent safety specifications and characteristics, including type, strength, and material. Failure to do so may result in product malfunction and possible injury to the operator and/or others.
ECK VALVE: Ensures that motor is ning in the proper direction and protects
ainst cavitation during flywheel spin-down.
te: The check valve on the Power Plate sures that the hydraulic motor will only turn the direction of a conventional tractor PTO.
• Replace locknuts and locking screws if you can tighten them without feeling considerable resistance for several turns before they are completely tight. Replace them with factory authorized parts or their equivalent.
OPERATIONAL SAFETY
• If hardware is not secure, or if some hardware is over-tightened, equipment failure may result, posing possible safety hazards.
• READ AND UNDERSTAND THE
OWNER’S MANUAL COMPLETELY. • Be familiar with all the skid loader controls
and know how to stop quickly. SAFETY DECALS
• NEVER operate equipment in the vicinity of bystanders or children. • If safety or instructional decals become
illegible or are removed, replace them immediately.
• Always wear the proper safety gear ( for eyes, hands, head, ears, etc.) when operating equipment.
• If you replace parts that have such decals
attached to them, make sure the decals are replaced with current versions, and that the decals are on the replacement parts before equipment is operated again.
• Never wear loose fitting clothing while in
the vicinity of the PTO shaft. • Keep all guards and shields in place. • New decals may be obtained from the
following address: • Operate equipment at ground level.
NEVER operate equipment in an elevated position. This could lead to serious injury or even death.

• Never use equipment in a manner for
which it was not designed.
Your safety or the durability and performance of your equipment may depend on a clear understanding of the information contained in this manual.
• When replacing fasteners, use the Standard Torque chart to tighten securely. (see below)

SAFETY WARNING!
Wear safety glasses while operating and servicing the equipment to prevent possible eye injury.
SAFETY WARNING!
Use hearing protection while operating machine to prevent possible hearing loss.
NOTE: When tightening two or more screws on the same part, DO NOT tighten screws completely right away, or one at a time. To avoid distortion, first tighten all screws in sequence to one-third of torque value, then tighten to two-thirds of torque value, then tighten to full value. H 1

be accomplished by tilting the bucket cylinder of the skid loader.)
3. Attach the PTO shaft of the implement to
the hydraulic motor on the Power Plate. 4. Be sure that the shaft is secured properly
and that all guards are in place.
Hook-up & OperationOOK-UP TO SKID LOADER
. Attach the Power Plate to the same mounting mechanism that attaches the loader bucket to the skid loader lift arms.
. Attach the hydraulic hoses to the remote hydraulics on the skid loader.
ote: The check valve allows the hydraulic oses to be connected to either port on most kid loaders. However, some skid loader ydraulic systems (e.g. Bobcat) allow one ircuit to be locked for continuous flow, thus equiring the pressure side to match that of he motor inlet.
ote: You will need to purchase the correct ouplers for the hydraulic hoses so that they atch your skid loader.
SAFETY WARNING!
e sure that the Power Plate is properly ecured and fastened to the skid loader efore each period of operation.
OOK-UP TO IMPLEMENT
. Hook up the implement to the 3-point hitch of the Power Plate.
. Adjust the center link so the implement stands at the desired level. (This can also
OPERATION 1. Adjust the placement and height of the
equipment that you intend to operate. 2. Make sure that Power Plate and
implement are attached securely. 3. With the skid loader engine running at an
idle, or low throttle, engage the remote hydraulics. This will turn the PTO shaft and the implement will begin to run.
4. Adjust the throttle so that the implement is
running at the desired speed. Note: The speed (rpm) of the hydraulic motor is dependant upon the hydraulic flow (gpm) and pressure (psi) generated by the skid loader. Therefore, the operator must ensure that the implement is running at the correct speed at all times.
SAFETY WARNING!
Never operate equipment in an elevated position. This could cause serious injury or even death.
Be sure that bystanders are clear of the area where you are operating.
Never operate equipment in the vicinity of children or pets.
