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, keep extra blades on hand.
Blade Safety
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death. Trying to
repair a damaged blade may result in discontinued
safety certification of the product.
•
Inspect the blades periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
g002479
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Before Inspecting or Servicing the
Blades
1. Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
