CAUTION
POTENTIAL HAZARD
Raising the mower deck for service or maintenance
relying solely on mechanical or hydraulic jacks could
be dangerous.
WHAT CAN HAPPEN
The mechanical or hydraulic jacks may not be enough
support or may malfunction allowing the unit to fall,
which could cause injury.
HOW TO AVOID THE HAZARD
DO NOT rely solely on mechanical or hydraulic jacks
for support. Use adequate jack stands or equivalent
support.
c) Clean out any grass build-up from underside of deck and in discharge chute.

Service Interval: Daily
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Lift deck and secure in raised position as stated in Section 5.1.4.
c) Inspect blades and sharpen or replace as required.
d) Re-install the blades (if they were removed) by placing a block of wood
between the front or rear baffles and the blade then torque the blade bolts
to 115-120 ft. lbs (156-165 N-M). Be sure the spring disk washer cone is
installed toward the bolt head. (See Figure 5).
NOTE: Another option for blade replacement is to use a 1” wrench on the
flat areas at the base of the spindle to hold the spindle assembly in place
while applying torque to the blade bolt.
