Speed Control Linkage Adjustment
Perform this adjustment if the mower creeps when the speed
control levers are in neutral and the neutral locks are
released.

wheels are clear of the ground.
2. Pull the forward speed control levers into neutral and engage
the neutral locks on the direction control levers.
3. Loosen the locknuts on the forward speed linkage.
4. Adjust the length of the rod until the roller just contacts the
pump control arm with no slack in the linkage. Adjust the
other side the same way.
5. Start the engine, move the throttle lever to FAST, and
release the neutral locks.

Turn the adjusting nut, counting the number of turns, to
shorten the rod until rear rotation just starts.
l
Turn the adjusting nut to lengthen the rod one-half the
number of turns you counted.
7. Tighten the locknut. Adjust the linkage on the other side in
the same manner.
8. Adjust both pump arm springs to a length of 4.5 - 4.9 inches
(115 - 125mm).
