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 misfunction 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) Tilt seat forward.
e) Loosen lock nuts from the ball joints on the two rods which connect the
motion control assemblies to the pump control arms (See Fig 10).
NOTE: The nuts to the rear of the unit on each rod have left-hand threads.

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 5.2.10.
h) Begin on either the left or right side of unit and bring the motion control
lever into the neutral position.
Adjust pump control rod length by rotating the double nuts on the rod in
the appropriate direction until the wheels slightly creep in reverse. (See
Fig 10). 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.
