1. Lift the mower so the rear wheels are off the ground. Disengage the
left side control linkage from the control arm.
2. Start the engine, move the throttle lever to the fast position and disengage the parking brake. Note if the left rear
wheel rotates and the direction the wheel rotates. Engage the parking brake and stop the engine. Do not adjust
the neutral setting with the engine running.

b If the wheel does rotate, proceed with Step 3 .
3. Loosen the neutral screw and rotate the control arm 5° in the opposite direction that the wheel turned. Tighten
the neutral screw.
