CAUTION
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. Raise the rear
of machine up and support with jack stands (or equivalent support) just
high enough to allow drive wheels to turn freely.
b)
Unhook seat latch and tilt seat forward.
c)
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.
d)
Run the unit at least 5 minutes with the drive levers at full forward speed to
bring hydraulic system oil up to operating temperature.
e)
Loosen lock nuts from the ball joints at each end of the RH pump control
linkage. (See Figure 13).
NOTE: The nut to the front of the unit on the RH rod has left-hand threads.

g)
The reverse indicator spring must be correct before the following
adjustments can be made. See Section 4.2.10.
NOTE: The motion control lever needs to be in neutral while making
any necessary adjustments.
The left rod assembly controls the left wheel and the right rod assembly
controls the right wheel.
