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 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 and the
parking brake.
2. Disengage the blade control switch (PTO).
3. Turn the ignition key to Off and remove the key.

Checking for Bent Blades
Note:
The machine must be on a level surface for
the following procedure.
1. Raise the mower deck to the highest
height-of-cut position; also considered the
'transport' position.
2. While wearing thickly padded gloves or other
adequate hand protection, slowly rotate blade to
be measured into a position that allows effective
measurement of the distance between the
cutting edge and a level surface.
