Refer to Figure 5-2:
3.
Rotate blade bolt (#1) until in alignment with access
hole “A”.
4.
Unscrew locknut (#5) to remove cutting blade (#2).
Blade bolt (#1) is keyed and will not turn freely.
5.
Both blades should be sharpened at the same angle
as the original cutting edge and must be replaced or
re-ground at the same time to maintain proper
balance in the cutting unit. The following precautions
should be taken when sharpening blades:
a. Do not remove more material than necessary.
b. Do not heat and pound out a cutting edge.
c. Do not grind blades to a razor edge. Leave a blunt
cutting edge approximately 1/16" thick.
d. Always grind cutting edge so end of blade
remains square to cutting edge and not rounded.
e. Do not sharpen back side of blade.
f. Both blades should weigh the same with not more
than 1 1/2 oz. difference. Unbalanced blades will
cause excessive vibration which can damage
gearbox bearings and create structural cracks.
Blade Rotation
Figure 5-1
Refer to Figure 5-1:
6.
Carefully check cutting edges of blades in relation to
blade carrier rotation to ensure correct blade
placement. Cutter blades must be installed with
cutting edge leading in rotation.
