Maintenance
Servicing the Cutting Blades
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.
WARNING
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 blades 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 blades
and set the parking brake. Turn the ignition key to off.
Remove the key and disconnect the spark plug wires
from the spark plugs.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 62). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
1. Cutting Edge
2. Sail
2. Inspect the blades, especially the curved area
(Figure 62). If you notice any cracks, wear, or a
slot forming in this area (item 3. in Figure 62),
immediately install a new blade.
Checking for Bent Blades
1. Disengage the PTO, move the motion control levers
to the neutral locked position and set the parking
brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Rotate the blades until the ends face forward and
backward. Measure from a level surface to the
cutting edge, position A, of the blades (Figure 63 ).
Note this dimension. For 36 inch mower decks use
Figure 64.
