10. IMPORTANT: Unbolt the seat platform from the mower
frame.
• Disconnect the two female spade connectors
from each other (from step #3).
• Reconnect the two female spade connectors to
the seat switch. This must be completed so that
the safety circuit is functioning properly.
Figure 4-1
• Re-attach the seat platform to the mower frame.
11. The steering control levers should be adjusted so that
they align within ± .125" (± 3.2mm) of each other when
in the neutral position. Figure 4-5
NOTE: The space between the ends of steering control
handles should be .50” ± .25” (12.2mm ± 6.35mm).
Figure 4-5
12. Check to make sure all tools or obstructions are

Park Brake Spring Adjustment
Occasionally check the park brake spring adjustment using
the following method:
1. This procedure does not require engine power,
therefore:
• Park the mower on level ground
• Disengage the deck clutch.
• Place the steering control levers in the park brake
position.
• Stop the engine.
• Remove the ignition key.
• Disconnect the negative battery cable.
2. On one side measure the park brake spring. It should
be compressed to 1.43"–1.48" (36.3–37.6mm). If it is
not, adjust the nylock nut until the proper spring
compression is achieved. Figure 4-6
3. Repeat for other side.
4. Reconnect the negative battery cable.
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.
