steering control levers are against the stops in the control
panel (see Figure 4-6).
2. Then, stop the mower and loosen the lock nut on the side
which is rotating too fast and turn the stop (set screw)
inward to stop the steering control lever sooner. Tighten
the lock nut on the stop and test again.
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 pressure
etc. may affect 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 control
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 position
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 4-7
3. Loosen the steering damper’s rear ball stud. Figure 4-8
4. Pull the damper spring housing past the point that the
internal spring is engaged. Figure 4-8
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.
