Leveling The Mower From; Side-To-Side - Toro 74419 Operator's Manual

A blade that is bent or damaged could
break apart and could seriously injure or
kill you or bystanders.
• Always replace bent or damaged
blade with a new blade.
• Never file or create sharp notches in
the edges or surfaces of blade.
Removing the Blades
The blades must be replaced if a solid object is
hit, if the blade is out of balance, or the blade
is bent. To ensure optimum 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.
Hold the blade end using a rag or thickly-padded
glove. Remove the blade bolt, curved washer,
blade stiffener, and blade from the spindle shaft
(Figure 39).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both
ends of the blade (Figure 40). Maintain the
original angle. The blade retains its balance if
the same amount of material is removed from
both cutting edges.

2. Check the balance of the blade by putting it on
a blade balancer (Figure 41). 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 40). Repeat this procedure until the
blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft
(Figure 39).
Important: The curved part of the blade
must be pointing upward toward the inside
of the mower to ensure proper cutting.
2. Install the blade stiffener, the curved washer
(cupped side toward the blade) and the blade
bolt (Figure 39).
3. Torque the blade bolt to 35-65 ft-lb
(47-88 N⋅m).

disengage the blade control switch.
2. Move the motion control levers outward to the

and wait for all moving parts to stop before
leaving the operating position.
