Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 28). Maintain the original angle. The blade

removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Fig. 29). 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. 28). Repeat this procedure until the
blade is balanced.

Installing the Blades
1. Place the blade onto the bolt, over cone washer. Select
proper number of spacer(s) for height-of-cut and slide
bolt into spindle (Fig. 27).
Important
The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.
2. Install remaining spacer(s) and secure with thin washer
and nut (Fig. 27).
3. Torque the blade bolt to 75–80 ft. lb. (101–108 N
m).
Servicing the Air Cleaner
Service Interval/Specification
Foam Element: Clean and re-oil after every 25 operating
hours.
Paper Element: Replace after every 100 operating hours.
Inspect the foam and paper elements, and replace them if
they are damaged or excessively dirty.
Note: Service the air cleaner more frequently if operating
conditions are extremely dusty or sandy.
Removing the Foam and Paper Elements
1. Disengage the power take off (PTO), set the parking
brake, and turn the engine off.
2. Clean around the air cleaner to prevent dirt from getting
into the engine and causing damage. Unscrew the cover
