MAINTENANCE
Servicing the Cutting Blades
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 injury or death. Trying to repair a damaged blade may result in discontinued safety certication of the
product.
1. Inspect blades periodically for wear.
2. Use care when checking the blades. Wrap the blades or wear gloves, and use caution when servicing the
blades. Only replace the blades, never straighten or weld them.
3. On multi-bladed machines, take care as rotating one blade can cause other blades to rotate.
Before Inspecting or Servicing the Blades
1. Park the machine on a level surface, disengage the PTO, stop the engine, engage parking brake, and remove
the key.
2. Disconnect the spark plug wires from the spark plugs.
Inspecting the Blades
1. Inspect the cutting edges (Figure 33).
2. If the edges are not sharp or have nicks, remove and sharpen the blade see “Sharpening the Blade,”
Chapter 3, page 3-50.
3. Inspect the blades, especially the curved area.
4. If you notice any cracks, wear, or a slot forming in this area, immediately install a new blade (Figure 33).
NOTE: Worn, bent, or out-of-balance blades cause vibration that can lead to irreparable damage to the
spindles, deck, or the engine.
