Leveling The Mower Deck - Toro 74722 Operator's Manual

Removing the Blades
Replace a blade if it hits a solid object, is out of balance,
or is bent. For best performance and continued safety
conformance of the machine, use genuine Toro replacement
blades. Replacement blades made by other manufacturers
may result in non-conformance with safety standards.
1. Hold the blade end using a rag or thickly padded glove.
2. Remove the blade bolt, curved washer, and blade from
the spindle shaft (Figure

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 49).
Note: Maintain the original angle.
Note: The blade retains its balance if you remove the
same amount of material from both cutting edges.

1. Sharpen at the original angle.
2. Check the balance of the blade by putting it on a blade
balancer (Figure 50).
Note: If the blade stays in a horizontal position, the
blade is balanced and ready to use.

only the end of the sail area

blade) and the blade bolt
3. Torque the blade bolt to 47 to 88 N·m (35 to 65 ft-lb).
