blade Sharpening
To properly sharpen the cutting blades, remove equal amounts of
metal from both ends of the blades along the cutting edges, parallel to
the trailing edge, at a 25° to 30° angle. See Figure 16.
NOTE: It is important that each cutting blade edge be ground equally
to maintain proper blade balance. A poorly balanced blade will cause
excessive vibration and may cause damage to the mower and result
in personal injury. The blade can be tested by balancing it on a round
shaft screwdriver. Grind metal from the heavy side until it balances
evenly.
WarninG
Always stop the motor and unplug mower before cleaning, lubricating
or performing any repairs or maintenance on the lawn mower. Always
wear safety glasses during operation or while performing any adjust-
ments or repairs.

blade installation
An unbalanced blade will cause excessive vibration when rotating
at high speeds. It may cause damage to mower and could break,
causing personal injury.
1.
Place the cutting blade, locking plate, and blade bolt on the motor
shaft and thread the blade bolt in finger tight.
NOTE: Make certain to replace the parts in the exact order in
which they were removed. When installing the cutting blade,
be sure it is installed with the curved ends pointing towards the
mower deck and not towards the ground.
2.
Torque the blade bolt down using a torque wrench to assure the
bolt is tightened properly. The recommended torque for the blade
bolt is 170-220 in. lbs.
To ensure safe operation of your mower, periodically check the blade
bolt for correct torque.
