3. 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 pres-
sure 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 damper
The steering dampers are spring loaded to return the con-
trol levers to the neutral position from the reverse position.
This gives the operator a sense of neutral during operation.
To set the steering dampers in the correct operating posi-
tion follow these steps:
1. Shut engine off, place steering control levers in the
park brake position, disengage deck clutch, remove
ignition switch key and disconnect negative battery
cable before doing any adjustments.
2. Place the steering control lever in the neutral position.
Figure 4-6
3. Loosen the steering damper’s front ball stud.
Figure 4-7
4. Pull the damper spring housing past the point that the
internal spring is engaged. Figure 4-7
5. Release the damper spring housing and allow the
internal spring to bring the housing back to the neutral
position.
6. Tighten the nut on the steering damper’s front ball
stud.
NOTE:
The damper must not bottom out when the
pump lever is fully stroked in either direction.
7. Reconnect the negative battery cable.
8. Lower and secure the seat platform.
9. To check, move the steering control lever to the
reverse position and release. The steering control lever
should return to the neutral position. If not, repeat
steps 1 through 6.
Steering control lever adjustment
The steering control levers can be adjusted for operator
comfort.
1. By loosening the nuts that attach the upper control
lever to the lower lever the upper control lever can be
pivoted to fit the operator’s personal preference (see
Figure 4-8).
2. The steering control levers should be adjusted so that
they align vertically with each other when in the neu-
tral position. Figure 4-9
