Checking for Bent Blades
1. Rotate the blades until the ends face forward
and backward.
2. Measure from a level surface to the cutting
edge, position A , of the blades ( Figure 65 ).

to hard surface
2. Position A
3. Rotate the opposite ends of the blades forward.
4. Measure from a level surface to the cutting edge
of the blades at the same position as in step 2
above.
Note: The dif ference between the dimensions
obtained in steps 2 and 4 must not exceed 3
mm (1/8 inch).
Note: If this dimension exceeds 3 mm (1/8
inch), the blade is bent and must be replaced.
Removing the Blades
Replace the blades if they hit a solid object, or if the
blade is out of balance or bent.
Note: Make note of the red-colored blade position.
From the normal user position, it is located on the
right side.
1. Lift the mower deck and secure in the raised
position. Refer to Raising the Mower Deck into
the Service Position ( page 18 ) .
2. Hold the blade end using a rag or thickly padded
glove.
3. Remove the blade, washer , and blade bolt that
secures the blade and blade driver ( Figure 66 ).

( Figure 66 ).
Sharpening the Blades
1. Use a le to sharpen the cutting edge at both
ends of the blade ( Figure 67 ).
Note: Maintain the original angle.
Note: The blade retains its balance if the same
amount of material is removed from both cutting
edges.
