Servicing the Cutting Blade
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
you may want to keep extra blades on hand.
Danger
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
Inspect the blade periodically for wear or
damage.
Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control (PTO) and set the parking brake. Turn the ignition
key to off. Remove the key and disconnect the spark plug
wire(s) from the spark plug(s).
Inspecting the Blades
1. Inspect the cutting edges (Fig 42). If the edges are not
sharp or have nicks, remove and sharpen the blades.
Refer to Sharpening the Blades on page 32.

blade.
