DIRECTIONAL PEDAL

The directional pedal controls the flow of hydraulic

fluid to the hydraulic drive motor. The pedal has

three positions: “forward,” “neutral,” and “reverse.”

The “forward” and “reverse” positions send hydraulic

fluid to the drive motor to propel the machine.

The “neutral” position is the position in which the

propelling pump sends no hydraulic fluid to the

propelling motor. The machine should not creep

when the “neutral” position is correctly adjusted.

Adjust the pedal linkages whenever the machine

creeps or after replacing the hydraulic propelling

pump or pump linkages. The pedal linkages should

also be adjusted whenever the reverse speed seems

excessive or inadequate. The pedal linkage also

includes a speed limiter. It limits forward speed to 2

mph (3.2 km/h) whenever the hopper is raised.

TO ADJUST DIRECTIONAL PEDAL LINKAGE

1. Stop the engine and set the machine parking

brake.

FOR SAFETY: Before leaving or servicing

machine; stop on level surface, set parking brake,

and turn off machine.

2. Block the machine tires and jack up the rear of

the machine at the designated location.

WARNING: Machine is unstable on jack.

Block machine tires before jacking machine

up.

3. Block up the machine with jack stands near the

designated jacking locations. Make sure the

rear tire clears the floor by 2 in (50 mm) and all

obstacles within a 24 in (610 mm) radius.

WARNING: Machine is unstable on jack.

Jack machine up at designated locations

only. Block machine up with jack stands.

4. Remove side engine access door.

5. Loosen the centering spring bracket retention

bolts and adjustment bolt jam nut.

CENTERING SPRINGS

A. Centering Springs

B. Pump Pintle Arm

C. Adjustment Bolt

D. Stationary Bracket

E. Retaining Bolt

F. Spring Bracket

6. Adjust the position of the spring bracket and

adjustment bolt so the hydraulic pump pintle

arm is held in a vertical position.

7. Snug the retention bolts.

8. Start the engine.

9. Move the directional control pedal into the

“forward” position and release it. The rear

wheel should stop rotating as soon as the

pedal is released. Adjust the spring bracket as

required.

10. Move the directional control pedal into the

“reverse” position and release it. The rear

wheel should stop rotating as soon as the

pedal is released. Adjust the spring bracket as

required.
