5.2.13 Motion control linkage adjustment.
POTENTIAL HAZARD
♦ Engine must be running and drive wheels must be
turning so motion control adjustment can be performed.
WHAT CAN HAPPEN
♦ Contact with moving parts or hot surfaces may cause
personal injury.
HOW TO AVOID THE HAZARD
♦ Keep fingers, hands, and clothing clear of rotating
components and hot surfaces.
POTENTIAL HAZARD
♦ Raising the mower deck for service or maintenance
relying solely on mechanical or hydraulic jacks could be
dangerous.
WHAT CAN HAPPEN
♦ The mechanical or hydraulic jacks may not be enough
support or may malfunction allowing the unit to fall,
which could cause injury.
HOW TO AVOID THE HAZARD
♦ DO NOT rely solely on mechanical or hydraulic jacks for
support. Use adequate jack stands or equivalent
support.
a) This adjustment must be made with the drive wheels turning. First raise the
frame and block up so that drive wheels can rotate freely.
b) 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
wiring harness.
c) Run the unit at least 5 minutes with the drive levers at full forward speed to
bring hydraulic system oil up to operating temperature.
d) Unhook seat latch and tilt seat forward.
e) Loosen lock nuts from the ball joints at each end of the LH pump control
linkage. (See Figure 18).
NOTE: The nut to the front of the unit on the LH rod has left-hand threads.
