Replacing The Grass Deflector - Toro 74272CP Operator's Manual

Sharpening the Blades
When sharpening blade, pieces of blade
could be thrown and cause serious injury.
Wear proper eye protection when sharpening
blade.
1. Use a file to sharpen the cutting edge at both
ends of the blade (Figure 74). 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 (Figure 75). 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
(Figure 76). Repeat this procedure until the
blade is balanced.

spring disk cone must be installed toward the

allow the lawn mower to throw objects in
the operator's or bystander's direction and
result in serious injury. Also, contact with
the blade could occur.

you install a cover plate, a mulch plate, or
a grass chute and catcher.

holding the deflector to the pivot brackets
(Figure 77).
2. Remove the damaged or worn grass deflector.
