Servicing the Cutting Blades
Service Interval: Yearly
Important: You will need a torque wrench to install the
blades properly . If you do not have a torque wrench or
are uncomfortable performing this procedure, contact
an Authorized Service Dealer.
Examine the blades for sharpness and any wear or damage
whenever you run out of gasoline; refer to Inspecting the
Blades (page 22). If the blade edge is dull or nicked, have it
sharpened or replace it. If the blade is worn, bent, damaged
or cracked, replace it immediately with a genuine Toro

replacement blade.
DANGER
A worn or damaged blade can break, and a piece
6
of the blade could be thrown toward the operator
or a bystander, resulting in serious personal injury
or death.
• Inspect the blades periodically for wear or
damage.

• Replace a worn or damaged blade.
Note: Maintain sharp blades throughout the cutting season,
because sharp blades cut cleanly without tearing or shredding
the grass blades. Tearing and shredding turns grass brown at
the edges, which slows growth and increases the chance of
disease.
Preparing to Service the Cutting Blades
1. Lock the handle in the vertical position (Figure 40);
refer to Adjusting the Handle Height (page 12).
