Maintenance
5. If adjustment is needed, loosen the nut against the
yoke and while applying slight rearward pressure
on the motion control lever, turn the head of the
adjustment bolt in the appropriate direction until
lever is centered (keeping rearward pressure on
the lever will keep the pin at the end of the slot
and allow the adjustment bolt to move the lever
to the appropriate position). Tighten lock nut.

Adjustment
WARNING
Engine must be running and drive wheels must
be turning so motion control adjustment can be
performed. Contact with moving parts or hot
surfaces may cause personal injury.
Keep fingers, hands, and clothing clear of
rotating components and hot surfaces.
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.
5. Loosen lock nuts from the ball joints at each end
of the pump control linkage (Figure 27).
