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.
4.1.5 Check mower blades.
Service Interval: Daily
a) Stop engine, wait for all moving parts to stop, and remove key. Engage
parking brake.
b) Lift deck and secure in raised position as stated in Section 4.1.4.
c) Inspect blades and sharpen or replace as required.
d) Re-install the blades (if they were removed) in the following order (See
Figure 3):
1) Install bushing through blade with bushing flange on bottom (grass)
side of blade.
2) Install bushing/blade combo into spindle.
3) Install blade bolt and spring disc washer. Be sure the spring disc
washer cone is installed towards the bolt head. Place a block of wood
between front or rear baffles and the blade then torque the blade bolts
to 55-60 ft-lbs. (75-81 N-m).
FIGURE 3
IMPORTANT: DO NOT use components other than the original blade, blade
bushing, spring disc washer, and blade bolt supplied with the unit. Failure to use
all original components and assembled as shown will increase the risk of a blade
bolt becoming loose or weak after striking a foreign object.
