Maintenance
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 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, you may want to keep
extra blades on hand.
WARNING
A worn or damaged blade can break, and a
piece of the blade could be thrown at you
or bystanders, 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
Park the machine on a level surface, disengage the
blade-control switch, move the motion-control levers
outward to the P position, shut off the engine, and
ARK
remove the key.
