Control Arm Rod Adjustment - Step 2
1. For both control arm rods, loosen jam nut on
ball joint end of control arm rod and adjust to ob-
tain a 1-1/4" measurement between jam nuts
(4-1/2" measurement between centers of ball
joints). Tighten jam nuts.

(view from underside of tractor)
Neutral Adjustment - Step 3
1. Turn the ignition key to the ON position and tog-
gle the FSC switch to the Neutral position (fully
retracted).
2. Tighten adjustment bolt in speed control actua-
tor to achieve approximately an 1/8" to 3/16"
gap between speed control actuator and speed
control stop.
3. Make identical adjustment to the other side of
tractor.
4. Start engine. If one or both drive wheels creep
forward, turn corresponding adjustment bolt in
(toward rear of mower). If drive wheels creep
backwards, turn corresponding adjustment bolt
out (toward front of mower).
NOTE: If the 1/8" to 3/16" gap between speed
control actuator and speed control stop can not
be maintained as neutral adjustments are made,
it will be necessary to adjust the length of the
control rod (Step 2). Increasing the length of the
control rod, decreases the gap. Shortening the
control rod, increases the gap.
