CHECK MOWER BLADES
Service Interval: Before each use or daily
Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
1. Lift deck and secure in raised position as stated
in the Clean Grass Build-Up Under Deck
section.
2. Inspect blades and sharpen or replace as
required.
3. Reinstall the blades (if they were removed) in
the following order:
A. Install (3) spacers, blade, spring washers
and bolt.
B. Install the bushing and blade onto spindle.
C. Apply lubricant to threads of blade bolt as
needed to prevent seizing. Copper-based
anti-seize preferable. Grease acceptable
substitute. Install blade bolt finger tight then
torque the blade bolts to 50-60 ft-lb (68-81
N-m).
WARNING
Incorrect installation of the blade or
components used to retain the blade can be
dangerous. Failure to use all original
components and assembled as shown could
allow a blade or blade component to be thrown
out from under the deck resulting in serious
personal injury or death.
Always use original equipment, i.e. blades,
blade bushings, and blade bolts as shown.
WARNING
Blades are sharp. Protect your hands
with gloves and/or wrap blades with a
heavy cloth when handling.
