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 21). 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
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 41);
refer to Adjusting the Handle Height (page 10).
