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:
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.
Steering Dampener
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
sense of neutral during operation. Set the steering
dampeners in the correct operating position as follows:
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
stud.
6.
To check, move the control lever to the reverse
position and release. The control lever should return
to the neutral position. If not, repeat steps 1 through 6.

Control Lever Adjustment
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.

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
move when the engine is running and the drive wheels are
rotating. Use only certified jack stands.
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.
