Maintenance
Tooth Sharpening (Quadco Option
Only)
NOTE: The teeth need to be kept sharp to maintain the
most effective operation of the attachment. Daily
inspection and touch up is recommended.
NOTE: The teeth can either be removed from the
attachment or remain installed for sharpening.
WARNING: Rotor must be stabilized to
prevent accidental rotation any time the
rotor is exposed for service work.
Note: Guard on grinder
removed for
photo clarity.
Leading Edge
NOTE: The Quadco cutter teeth have been heat treated
to a specific hardness. Care must be taken to
avoid overheating the leading edge of the tooth
while sharpening. If the coloring in the tooth
changes to either a blue or brown during the
sharpening, you have removed the temper and
the tooth will not hold it's cutting edge.
NOTE: When re-sharpening teeth using machine shop
equipment, avoid overheating the teeth by using
a flood coolant system.
NOTE: When re-sharpening teeth using a hand grinder,
avoid overheating the tooth by lightly grinding
each tooth, moving across the entire row of
teeth before returning to the first tooth to repeat
the procedure.
NOTE: Sharpen each tooth equally to maintain rotor
balance. Always return tooth to it's original
location if it is removed from the rotor for
sharpening.

Can be sharpened
up to this point.
Dashed lines represent
the approximate angle
for each time the tooth
is sharpened.
NOTE: It is not necessary to match the factory angle
on the underside of the cutting edge when re-
sharpening. Sharpen each tooth at a slight angle
for each successive sharpening (represented by
the dashed lines shown in the illustration above).
When the cutting edge of the tooth is 1-1/8 in.
from the back side of the tooth, the tooth must
be replaced.
