Sharpening the Blades
Warning
When you sharpen the blade, pieces of the blade
could be thrown and cause serious injury.
Wear proper eye protection when you sharpen the
blade.
1. Use a file to sharpen the cutting edge at both ends of the
blade at the original angle (Fig. 27).

Note: The blade retains its balance if the same amount
of material is removed from both cutting edges.
2. Check the balance of the blade by putting it on a blade
balancer (Fig. 28). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off the end of the
sail area only (Fig. 26). Repeat this procedure until the
blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Fig. 26).
Important
The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.
2. Install the flat washer, lock washer, and blade bolt
(Fig. 26).
Note: Torque the blade bolt to 85–110 ft-lb
(115–150 N⋅m).

Cleaning the Cooling System
Clean the air intake screen before each use. Remove any
buildup of grass, dirt, or other debris from the engine air
intake.
Servicing the Air Cleaner
Foam Element: Clean and oil it after every 25 operating
hours.
Paper Element: Replace it after every 100 operating hours.
Note: Service the air cleaner more frequently (every few
hours) if the operating conditions are extremely dusty or
sandy.
Removing the Foam and Paper Elements
1. Disengage the PTO, set the parking brake, stop the
engine, and remove the key.
2. Clean around the air cleaner to prevent dirt from getting
into the engine and causing damage.
3. Unscrew the knob and remove the air cleaner cover
(Fig. 29).
