Servicing The Cutting Blades - Toro Z Master Professional 7000 Series Operator's Manual

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.
Blade Safety
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. Trying to
repair a damaged blade may result in discontinued
safety certification of the product.
•
Inspect the blade periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
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.
