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.
Inspect and check the blades every 8 hours.
Before Inspecting or Servicing the
Blades
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Move the throttle lever to the Slow position, stop the
engine, remove the key, and wait for all moving parts to
stop before leaving the operating position.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 71). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
2. Inspect the blades, especially the curved area (Figure
71). If you notice any damage, wear, or a slot forming
in this area (Figure 71), immediately install a new blade.
1. Cutting Edge
2. Curved Area
DANGER
If you allow the blade to wear, a slot will form
between the sail and flat part of the blade.
Eventually a piece of the blade may break
off and be thrown from under the housing,
possibly resulting in serious injury to you or
bystanders.
• Inspect the blade periodically for wear or
damage.
• Never try to straighten a blade that is bent
or weld a broken or cracked blade.
• Replace a worn or damaged blade.
Checking for Bent Blades
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
