Mower-Deck Maintenance
Blade Safety
• Inspect the blades periodically for wear or damage.
• Use care when checking the blades. Wrap the blade(s) or wear gloves and use caution
when servicing them. Only replace damaged 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.
Blade Service
To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and
replacement, keep extra blades on hand.
Replace the blades if they hit a solid object, or if the blade is out of balance or bent.
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
ARK position.
2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving
the operating position.
3. Disconnect the spark-plug wires from the spark plugs.
Checking for Bent Blades
The machine must be on a level surface for this procedure.
1. Raise the mower deck to the highest height-of-cut position.
2. While wearing thickly padded gloves, or other adequate hand protection, slowly rotate
the blade into a position that allows you to measure the distance between the cutting
edge and the level surface.

3. Measure from the tip of the blade to the level surface.
