CUTTERBAR Continued.
How to sharpen and balance the cutterbar: A slightly
worn cutterbar may be re-sharpened. Both cutting edges
must be sharpened equally to ensure balance. Sharpen the
cutterbar every 25 mowing hours or more frequently if con-
30 -45
ditions require. Remove the cutterbar from the mower and
clean using a brush and water. Inspect the cutterbar for signs
CS040
of damage.
WARNING - PREVENT ACCIDENTS : DO NOT use a
damaged or excessively worn cutterbar.
Sharpen both cutting edges with a flat file to restore the orig-
CS025
inal cutting edge.
Ensure that the cutterbar is balanced. Use a screw driver with
a round shaft to support the cutterbar through its centre hole.
Hold the cutterbar horizontal and then release. A balanced
CS026
cutterbar will remain horizontal. If the cutterbar is not bal-
anced the heavy end will rotate downwards. Sharpen the
heavy end until the cutterbar is correctly balanced.
