Servicing The Cutting Blades - Toro 74410 Operator's Manual

Important Refer to your engine operator's manual for additional maintenance procedures.
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do
any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.

Servicing the Cutting Blades

Maintain sharp blades throughout the cutting season,
because sharp blades cut cleanly without tearing or
shredding the grass blades. Tearing and shredding turns the
grass brown at the edges, which slows growth and increases
the chance of disease.
Check the cutter blades daily for sharpness, and for any
wear or damage. File down any nicks and sharpen the
blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade. For
convenient sharpening and replacement, keep extra blades
on hand.
Danger
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's or
bystander's area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the Blades
1. Park the machine on a level surface, disengage the
blade control (PTO), and set the parking brake.
2. Turn the ignition key to Off and remove the key.
3. Disconnect the spark plug wire(s) from the spark
plug(s).
Caution
Inspecting the Blades
1. Inspect the cutting edges (Fig. 23).
