MAINTENANCE
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. If not see
reverse spring detent adjustment.
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.
Reinstall the seat rod and check the wiring
harness to the seat safety switch for a good
connection and return the seat to the normal
position.
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.
Deck Lift Power Unit
Check oil level of unit located under the seat
every 25 hours and add oil if necessary.
Remove the vent plug on the power unit and
only fill to within 3/4 of an inch below the top
with 15W-50 oil.
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.
