Greasing And Lubrication - Toro 74501 Operator's Manual

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 22). Maintain the original angle. The blade
retains its balance if the same amount of material is
removed from both cutting edges.

1. Sharpen at original angle
2. Check the balance of the blade by putting it on a blade
balancer (Fig. 23). 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. 21). Repeat this procedure until the
blade is balanced.

Important The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.

blade) and blade bolt (Fig. 21). Torque the blade bolt to
35–65 ft.-lb. (47–88 N m).
