3. Do this for each side.

Refer to Figure 3-3 on page 15. To adjust the stops for driving straight when control levers are against the stops during operation:

NOTE: The dampener must not bottom out when the pump lever is fully stroked in either direction.

Control Lever Adjustment

4.Determine which drive tire is rotating too fast when both control levers are against the stops. Then stop the tractor and loosen the lock nut on the side which is rotating too fast and turn the stop (set screw) inward to stop the control lever sooner. Tighten the lock nut on the stop and test again. Repeat this procedure until unit drives straight.

NOTE: Since this is a hydrostatic drive, variables such as temperature of oil, efficiency of pumps and motors, tire pressure etc. may effect the consistency of the ability to rely on the stops to drive straight without the operator making minor steering adjustments with the control arms.

Refer to Figure 3-5

The control levers may be adjusted vertically and pivoted forward or backward for operator comfort. Adjust the control levers vertically by removing the capscrews, flat washers, and locknuts that attach the upper control levers to the lower control levers. Reposition the upper control levers to a height that fits the operator’s personal preference. Reassemble the capscrews, flat washers, and locknuts in the same order they were removed without tightening them. Pivot the upper control levers forward or backward to again fit the operator’s personal preference. Verify that the control levers align with each other when in the neutral position and tighten the locknuts to correct torque.

Refer to Figure 3-4:

 

 

 

 

 

 

 

 

The steering dampeners, one for each control lever, are

 

 

 

 

 

 

 

 

spring loaded to return the control levers to neutral

 

 

 

 

 

 

 

 

position from reverse position. This gives the operator a

 

 

Upper

 

 

 

 

 

sense of neutral during operation. Set the steering

 

 

 

 

 

 

Control

 

 

 

 

 

dampeners in the correct operating position as follows:

 

 

 

 

 

 

Lever

 

 

 

 

 

 

 

 

 

 

1. Place control lever in the neutral position.

 

 

 

 

 

 

 

 

2. Loosen steering dampener’s front ball stud.

 

 

 

 

 

 

 

 

3. Pull the dampener spring housing, to the front, past

 

 

 

 

 

 

 

 

the point that the internal spring is engaged.

 

 

 

 

 

 

 

 

4. Release the dampener spring housing and allow the

 

 

 

 

 

 

 

 

internal spring to bring the housing back to the neutral

 

 

 

 

 

 

 

 

position.

 

 

 

 

 

 

 

 

5. Tighten the nut on the steering dampener’s front ball

 

 

 

 

 

 

 

 

 

 

Capscrews with

Park Brake Adjustment

 

Occasionally check the park brakes and adjustment using

 

the following method:

 

1. Position the control levers in the neutral position.

 

Disengage the deck clutch.

 

 

 

 

 

! WARNING!

 

 

 

 

 

Make certain machine is secure when it is raised and placed on

 

 

 

 

 

the jack stands. The jack stands should not allow the machine to
