Control Lever Stops
The steering control lever stops (see Figure 6-4 &
Figure 6-5) 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 steering control levers are pushed forward
against the stops.
To keep the pumps from bottoming out internally use
the following procedure:
NOTE: This adjustment normally 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.

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. Always reconnect the seat switch to the
mower harness.
Pump damage will occur if these stops are set
incorrectly.
