Idle the machine for a while, and then switch
off the lapping machine to stop rotation of
the reel cutter (cutting cylinder) when contact
noise is no longer heard.
Raise the mower unit that requires back
lapping.
Wash off or wipe off with cloth etc. the
abrasive from the reel cutter (cutting
cylinder), then check it for sharpness.
Repeat steps 6 to 15 until the entire range
(three or four points) of the reel cutter
(cutting cylinder) will be uniformly
sharpened.
Lower the mower unit that requires back
lapping to the ground.
Finally, apply the abrasive on the entire
blade width of the reel cutter (cutting
cylinder) and perform final back lapping.
Stop the rotation of the reel cutter (cutting
cylinder), and then carefully and thoroughly
wash off any remaining abrasive.
While checking the blade for sharpness,
adjust blade engagement.
Raise the mower unit.
Install the belt for the mower unit.
Sharpening of Reel Cutter (Cutting
Cylinder)
The sharpening of the reel cutter (cutting
cylinder) consists in maintaining its roundness
and creating a relief (second edge face).
This work should be performed if the
sharpness cannot be restored, even after back
lapping, or if the relief (second edge face) has
worn away.
Sharpen the reel cutter (cutting cylinder) when
the sharpness cannot be restored, even after
back lapping, or when the relief (second edge
face) has worn away, there is full contact or
back lapping takes too much time.
In addition, if the reel cutter (cutting cylinder)
becomes worn and its shape conical, perform
cylindrical grinding to return it to a cylindrical
shape.
For sharpening the reel cutter (cutting
cylinder), contact your dealer or Baroness
unless you have a grinding machine.
