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.

Operate conventional PTO-powered implements:

The Power Plate is a unique attachment that can be used to operate conventional PTO-

powered implements that have a Category-1 3-Point hitch. Care should be taken, however, not to

use implements that excessively twist the structure of the Power Plate, e.g.: brush cutters with

single blades greater that 50” in diameter.

Easy attachment to standard skid loaders:

The Power Plate is attached to a standard skid loader with the “quick-attach” mechanism

where the bucket would normally be located. Compatible skid loaders include: Bobcat, New

Holland, John Deere, and Case IH, as well as several other brands.

Available horsepower:

The horsepower generated by the hydraulic motor is dependent upon the capacity of the

skid loader. Hydraulic horsepower (hp) can be determined using the following formula:

hp (horsepower) = gpm (gallons per minute) x psi (pounds per sqare inch) / 1714.

Thus, if a skid loader has 18 gpm flow and 2500 psi, the Power Plate would be capable of

generating 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.

THREE POINT HITCH ARMS: Used to

secure implements to the skid loader

attachment.

• Keep the equipment and attachments in

good operating condition.

CENTER LINK: Used to secure implements

to the skid loader attachment and adjust to

level position.

• Keep all guards and shields in place

during operation.

HYDRAULIC MOTOR: Powers implements

that are attached to the unit.

• Replace all worn, damaged, unusable,

missing, or lost safety shields before

operating the equipment.

HYDRAULIC HOSES: Connect to the remote

hydraulics of the skid loader in order to

transfer power to the hydraulic motor.

• Keep nuts, bolts, and screws tight to help

ensure the safe operation of equipment.

STABILIZER BAR: Secures to right three

point hitch arm and keeps implements from

swinging 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.

CHECK VALVE: Ensures that motor is

running in the proper direction and protects

against cavitation during flywheel spin-down.

Note: The check valve on the Power Plate

ensures that the hydraulic motor will only turn

in 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.

• DO NOT make adjustments to the

machine while it is running. Make sure

that the engine is shut off before working

on the machine or making adjustments.

SAFETY WARNING!

If anything in this manual is unclear or

hard to understand, contact your dealer or

call Harper Industries (800-835-1042) for

clarification before proceeding.

• 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.

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.

HOOK-UP TO SKID LOADER

1. Attach the Power Plate to the same

mounting mechanism that attaches the

loader bucket to the skid loader lift arms.

2. Attach the hydraulic hoses to the remote

hydraulics on the skid loader.

Note: The check valve allows the hydraulic

hoses to be connected to either port on most

skid loaders. However, some skid loader

hydraulic systems (e.g. Bobcat) allow one

circuit to be locked for continuous flow, thus

requiring the pressure side to match that of

the motor inlet.

Note: You will need to purchase the correct

couplers for the hydraulic hoses so that they

match your skid loader.

SAFETY WARNING!

Be sure that the Power Plate is properly

secured and fastened to the skid loader

before each period of operation.

HOOK-UP TO IMPLEMENT

1. Hook up the implement to the 3-point

hitch of the Power Plate.

2. Adjust the center link so the implement

stands at the desired level. (This can also

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-u

& O

eration 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.
