Begin with either side and put the motion control
lever into the neutral position. Adjust the motion
control linkage by rotating the double nuts (D) in
the proper direction until the wheel stops rotating.
See illustration. Move the motion control lever
forward then into the neutral position and place it
into the neutral slot. The wheel must be stopped
completely at this point. Now do the same in
reverse and release the lever. The lever should
return to neutral on its own.
Run engine full throttle to make sure wheels do
not rotate. Readjust if any rotation occurs.
Repeat the whole process for the opposite side
and tighten the nuts against the ball joints.
Turn machine off.
Cutter Housings
Grease housings once weekly or every 40 to 50
hours of use. Use a good synthetic grease. Pump
grease in until a small amount purges from the
popet on the underside of the deck. Check the
torque of the pulley bolt 45 ft/lbs should be
maintained.

Mule Drive System Adjustment
As the mule drive belt wears and elongates, some
spring tension must be maintained on the left (self-
adjusting) mule drive idler.
For best performance, occasionally adjust the right
(fixed) mule drive idler position in the slot so central
axis of idler pulleys align.

The system is pre-filled and factory sealed. In the
event it becomes necessary to replace oil in the
reservoir, the cylinder or cylinders must be in the
retracted position. Carefully remove all dirt and
debris from around the fill plug and remove the
plug. Fill to the lower edge of the hole with 15W-50
synthetic oil and replace the plug firmly to reseal
the system.
