CAUTION
Raising the mower deck for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous. The
mechanical or hydraulic jacks may not be enough
support or may malfunction allowing the unit to
fall, which could cause injury.
Do Not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands or
equivalent support.
1. This adjustment must be made with the drive
wheels turning. First raise the rear of machine
up and support with jack stands (or equivalent
support) just high enough to allow the drive
wheels to rotate freely.
2. Unhook seat latch and tilt seat forward.
3. Remove the electrical connection from the seat
safety switch, located directly to the left of the seat
switch assembly beside the hydraulic oil reservoir.
Temporarily install a jumper wire across the
terminals in the connector of the main wiring
harness.
4. Run the unit at least 5 minutes with the drive
levers at full forward speed to bring hydraulic
system oil up to operating temperature.
