Control Lever Stops
The internal steering control lever stops (see Figure4-4)
are designed to keep the pumps from bottoming out
internally. The external steering control lever stops (see
Figure 4-5) may be adjusted to help the mower drive straight
when the steering control levers are pushed forward against
the stops.
To keep the pumps from bottoming out internally use
the following procedure:
This adjustment is only required if the hydraulic pump(s)
have been replaced.
1. To make the first adjustment the mower engine must
not be running.
2. Check to make sure the steering control levers are
against the stops before the pumps are bottomed out
internally.
3. To do this, gently and slowly move the steering control

Do not operate the mower without plugging the
mower’s wiring harness into the seat switch. This
switch is an important part of the safety start
interlock system. Serious injury can result if the
seat switch is not plugged into the mower’s wiring
harness.
Never operate the mower with a non-functioning
seat switch. Check the mower’s safety start interlock
system daily, prior to operation, to make sure the
seat switch is functioning properly.
Pump damage will occur if these stops are set
incorrectly.
