1. Make sure vehicle is on a level surface and elevator

assembly is down.

2. Start vehicle engine, raise and lower vehicle box

several times.

3. Move the high low switch to the LOW position to

operate the elevator and conveyor hydraulic motors.

4. Check all fittings and connectors for leaks. Repair

as needed.

5. Raise the truck bed, stop vehicle engine, put

cylinder support on the lift cylinder and check the

high/low tank oil level.

6. Add 10W-30 hydraulic fluid or equivalent until oil is 1

inch (25 mm) below the filler neck.

WARNING

Escaping hydraulic oil under pressure can have

sufficient force to penetrate the skin, causing serious

injury.

After assembly of hydraulic system and before starting

vehicle engine to apply pressure to system, make sure

connections are tight and that hoses and fittings are

not damaged.

After applying pressure to the system, use a piece of

cardboard or wood, not your hands to check for leaks.

If system requires repair, make sure pressure is

relieved before disconnecting hoses.

If injured by escaping fluid, see a doctor at once.

Serious infection or reaction can develop if proper

medical treatment is not administered immediately.

WARNING

Never do service on the vehicle without the truck bed

or accessory lifted and the cylinder support installed

on the cylinder rod. When you do service on the

vehicle without the cylinder supported, the bed or

accessory can accidentally lower and cause injury or

death.

NOTICE

DO NOT overfill reservoir.

ADJUSTMENTS 4

4 ADJUSTMENTS

4.1 GENERAL ________________________________________________________________

1. Adjustments and maintenance should always be

performed by a qualified technician. If proper

adjustment cannot be made, contact an authorized

Cushman Dealer.

2. Replace, do not adjust, worn, or damaged

components.

3. Long hair, jewelry, or loose fitting clothing may get

tangled in moving parts.

4. Do not change governor settings or overspeed the

engine.

7. Keep hands and feet away from moving parts. If

possible do not make adjustments with the engine

running.

4.2 LEVELING VEHICLE _______________________________________________________

1. Inflate the caster wheel tire to 10 – 12 psi (0.69 –

0.82 BAR).

2. Adjust pressure in air shock to level the vehicle with

operator in seat and Core Harvester attached. Air

shock minimum pressure is 55 psi (3.79 BAR) and

maximum pressure is 150 psi (10.34 BAR).

4.3 ADJUSTING CONVEYOR BELT ______________________________________________

Loosen bearing mounting nuts. Adjust rods (1) as

required to tighten conveyor belt only tight enough to

rotate the belt. Over-tightening will add to torque required

to rotate belt and shorten life of belt lacing. After

adjusting belt, make sure the belt is centered in the

trough. Make centering adjustments with the conveyor

belt rotating slowly. The belt will move away from the end

of belt roller being tightened. Tighten bearing mounting

nuts.

Figure 4.1

WARNING

To prevent injury, depress clutch pedal and shift

transmission to Neutral, engage parking brake, stop

engine, and remove key from ignition switch before

making any adjustments or performing maintenance.

Make sure the vehicle is parked on a solid and level

surface. Never work on a vehicle that is supported

only by the jack. Always use jack stands.

If only the front or rear of the vehicle is raised, place

chocks in front of and behind the wheels that are not

raised.

Never do service on the vehicle without the truck bed

or accessory lifted and the cylinder support installed

on the cylinder rod. When you do service on the

vehicle without the cylinder supported, the bed or

accessory can accidentally lower and cause injury or

death.

CAUTION

Be careful to prevent entrapment of the hands and

fingers between moving and fixed components of the

machine.

WARNING

Bodily injury can occur when air shock pressure

exceeds 150 psi (10.34 BAR).

To prevent structural damage to the Truckster XD a

minimum of 55 psi (3.79 BAR) air pressure is required

in the air shock at all times.

NOTICE

To adjust conveyor belt, remove curved shield (2)

from front of conveyor. Shield must be installed after

belt is adjusted.

5 OPERATION

5.1 GENERAL OPERATION ____________________________________________________

1. BEFORE using vehicle with attachment, place

vehicle on level surface.

2. Check the vehicle, as viewed from front to make

sure it is level.

3. Add air, 55 to 150 psi (3.79 to 10.34 BAR) to the air

shock as required, to level vehicle with operator in

seat.

4. Inflate caster wheel tire to 10–12 psi (0.69–0.82

BAR).

5. Install the windrow (blade assembly) using CENTER

mounting holes when gathering cores in a straight

line such as back and forth across a green or on

fairways. For circular patterns, use RIGHT mounting

holes for COUNTERCLOCKWISE travel, LEFT

mounting holes for CLOCKWISE travel.

6. ALWAYS remove the windrow (blade assembly)

when transporting long distances. For short

distances, use lift handle to raise elevator to over-

center position.

The added weight of the windrow blades increase the

shock loading to Core Harvester and vehicle when

traveling over rough ground.

7. Move the high/low switch to the LOW position to

operate the elevator and conveyor motors. Move the

high low switch to the OFF position to stop the

motors.

8. While harvesting cores on greens, operate the

vehicle at the recommended engine RPM. Place the

drive transmission in FIRST gear and auxiliary

transmission in LOW range.

Note: Reduce speed on rough or steep terrain.

9. When used on fairways, place the drive

transmission in SECOND gear, auxiliary

transmission in LOW range.

Note: Never use other gears. Elevator may clog.

10. Raise the elevator to over-center position and move

high low switch to the OFF position to stop elevator

when making turns after each pass.

11. For minimum wear on the elevator boot, always

lower the elevator to the ground when dumping a

load of cores.

12. ALWAYS stop elevator rotation and shut off vehicle

engine before leaving operator’s seat.

5.2 LUBRICATION ____________________________________________________________

Use a lithium base pressure gun grease at the three (3)

grease fittings every 20 hours of operation.

Figure 5.1

WARNING

Bodily injury can occur when air shock pressure

exceeds 150 psi (10.34 BAR).

To prevent structural damage to the Truckster XD a

minimum of 55 psi (3.79 BAR) air pressure is required

in the air shock at all times.

WARNING

Failure to remove the windrow (blade assembly)

before transporting long distances can result in the

raised extension blades hitting objects or bystanders

resulting in injury.
