MAINTENANCE
Deck Lift Power Unit
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.
Mule Drive System Adjustment
Only for the 72” deck.
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.
Caster Wheels
Check every 200 hours. Lift front of unit off of
ground so caster wheels can rotate freely.
Tighten caster bolt (34) then back off 1/2 turn.
Check that wheel rotates freely. If wheel does
not rotate freely back the caster bolt off in 1/4
turn increments until wheel rotates freely.
Foam filled tires or solid tires will void the
warranty.
