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. 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 RH pump control
linkage (See Figure 15).
NOTE: The nuts to the rear of the unit on each rod have left-hand threads.

RH MOTION CONTROL ADJUSTMENT
f)
Start engine.
Brake must be engaged and motion control levers out to
start engine. Operator does not have to be in the seat because of the
jumper wire being used.
Run engine at full throttle and release brake.
g) The reverse indicator spring must be correct before the following
adjustments can be made. See Section 5.2.9.
h) Bring the RH motion control lever into the neutral position. Adjust RH pump
control rod length by rotating the double nuts on the rod in the appropriate
direction until the wheels slightly creep in reverse (See Figure 15). Move the
motion control lever to the reverse position and while applying slight pressure
to the lever, allow the reverse indicator spring to bring the levers back to
neutral. The wheel must stop turning or slightly creep in reverse.
NOTE: The motion control lever needs to be in neutral while making
any necessary adjustments.
