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.
Servicing the Cutting
Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
keep extra blades on hand.
Before Inspecting or Servicing the
Blades
1. Park the machine on a level surface, disengage
the blade-control switch, and move the
motion-control levers outward to the P
position.
2. Shut off the engine, remove the key, and
disconnect the spark-plug wires from the spark
plugs.
