Sharpening a Blade
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 32).
Maintain the original angle. The blade retains its
balance if the same amount of material is removed from
both cutting edges.

Installing the Blades
1. Hold the blade end using a rag or thickly padded glove.
2. Install the washer, spindle cup, blade, washer, and blade
bolt (Fig. 31).
Important
The sail (curved part of the blade) must be
pointing up toward the inside of the mower to ensure
proper cutting.
3. Tighten the nut to 80 to 100 ft.-lb. (109 to 136 N m).
Greasing the Mower
Grease the mower after every 25 operating hours or once a
year, whichever occurs first. Grease more frequently when
operating conditions are extremely dusty or sandy.
Grease Type: General-purpose grease.
How to Grease
1. Disengage the PTO, set the parking brake, lower the
attachment lift, stop the engine, and remove the ignition
key.
2. Clean the grease fittings (Fig. 34) with a rag.
