Control lever stops

The control lever stops (Fig. 11-21) are designed to do two things: First,
and most important, they must keep the pumps from bottoming out
internally. Secondly, the stops may be adjusted to help drive straight when
the control levers are pushed forward against the stops.
To keep the pumps from bottoming out internally use the following
procedure:
1. To make the first adjustment the tractor engine must NOT be
running.
2. Check to make sure the control levers are against the stops before the
pumps are bottomed out internally.
To do this, gently and slowly move the control levers forward and
feel if there is some resistance on the pump lever before the control
levers hit the stops. Check one side at a time. If you sense that the
pump arms are stopping the forward motion of the control arms,
loosen the jam nut on the adjustable stop of the corresponding side
and turn the stop (set screw) inward to stop the control levers slightly
before the pump bottoms out. Lock in place when the adjustment is
correct by re-tightening the jam nut.
3. Do this for each side.
To adjust the stops for driving straight when control levers are against
the stops during operation:
1. 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.
Steering dampener
This steering dampener (Fig. 11-22) is spring loaded to return the control
levers to the neutral position from the reverse position. This gives the
operator a sense of neutral during operation.
To set the steering dampeners in the correct operating position follow
these steps:
1. Place the control lever in the neutral position.
2. Loosen the steering dampener's front ball stud.
3. Pull the dampener spring housing pass 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.

Control lever adjustment
The control levers can be adjusted for operator comfort. By loosening
the cap screws that attaches the upper control lever to the lower lever (Fig.
11-23), the upper control lever can be pivoted to fit the operator's personal
preference.
The control levers should be adjusted so that they align with each other
when in the neutral position.
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: Never work under the machine or attachment
unless it is safely supported with jack stands. 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. Use only appropriate jack stands, with a
minimum weight rating of 2000 pounds to block the unit up. Use
in pairs only. Follow the instructions supplied with the vehicle
stands
