Mower Maintenance
Blade Safety
•
Inspect the blades 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
one blade can cause other blades to rotate.
•
Replace worn or damaged blades and bolts in sets
to preserve balance.

sharp. For convenient sharpening and replacement,
keep extra blades on hand.
