Blade Care
WARNING:

sharpening or replacement, protect your hands with
a pair of heavy gloves or use a heavy rag to hold the
blade.
WARNING!
After striking a foreign object, stop the
rider. Thoroughly inspect the machine for any
damage. Repair the damage before starting and
operating.
Periodically inspect the blade adapter for cracks, especially if you
strike a foreign object. Replace when necessary. Follow the steps
below for blade service.
1. The deck on the rider should not be removed. To access the
blades the rider can be placed on a lift, driven on ramps or
placed on jack stands.

Be sure the rider is secured and the
parking brake is set when removing the blades.

4. Balance the blade on a round shaft screwdriver to check.
Remove metal from the heavy side until it balances evenly.
When sharpening the blade, follow the original angle of
the blade and cutting edge. Grind or file each cutting edge
equally to keep the blade balanced.
WARNING:
An unbalanced blade will cause
excessive vibration when rotating at high speeds. It
may cause damage to the motor or the mounting
hardware which could cause personal injury.
5. Visually inspect the blade adapter for any damages or
cracks.
6. Lubricate the inner surface of the blade adapter with light
oil. Slide the blade adapter onto the deck motor spindle.
Place the blade on the adapter such that the side of the
blade marked "Bottom" (or with part number) faces the
ground when the rider is in the operating position. Make
sure that the blade is aligned and seated on the blade
adapter flanges.
6. Place blade bell support on the blade. Align notches on the
blade bell support with small holes in blade.
7. Replace hex bolt and tighten torque to 450 in. lbs. min., 600
in. lbs. max.
To ensure safe operation of your rider, periodically check the
blade bolt for correct torque.
