Maintenance
Sharpening the Blades
1.
Use a file to sharpen the cutting edge at both
ends of the blade (Fig. 27). Maintain the original
angle. The blade retains its balance if the same
amount of material is removed from both cutting
edges.

2.
Check the balance of the blade by putting it on a
blade balancer (Fig. 28). If the blade stays in a
horizontal position, the blade is balanced and can
be used. If the blade is not balanced, file some
metal off the end of the sail area only (Fig. 26).
Repeat this procedure until the blade is balanced.

Mismatch
If one cutter blade cuts lower than the other, correct
as follows:
1.
Stop the engine, remove the key and disconnect
the spark plug wire(s) from the spark plug(s).
2.
Adjust the tire pressure in all tires to
specifications and check that the blades are not
bent. Refer to Checking for Bent Blades on page
14.
3.
Set the height-of-cut to the 2-1/2" position.
Refer to Adjusting the Height-Of-Cut in the
Operation section. Make sure the clevis pins are
resting on the frame cushions.
4.
Rotate the blades so the tips line up with one
another. The blade tips must be within 1/8"
(3 mm) of each other. If the blade tips are not
within 1/8" (3 mm) of each other, add shims
(Part No. 3256-24) between the appropriate
spindle housing and the bottom of the cutting
unit to align the blades.
