Caution
Before cutting newspaper as a test, be sure to
stop the engine and wear gloves to protect
your hands.

may injure your hand or fingers.

Before adjusting the blade engagement, be
sure to set the Traveling/Working selector

Adjust the engagement between the reel cutter
(cutting cylinder) and the bed knife (bottom
blade) so that newspaper (one piece) will be
cut cleanly by the edge of both blades when
the blades in their entirety come slightly into
contact with each other via the cutter
adjustment nuts.
Insert a strip of newspaper into the space
between the reel cutter (cutting cylinder) and
the bed knife (bottom blade) at an angle of 90
degrees.
Then, rotate the reel cutter (cutting cylinder)
counter-clockwise (when you face the mower
unit from the left) to check the sharpness of the
blades.
Check the sharpness of the entire range (three
or four points from left edge to right) of the reel
cutter (cutting cylinder).
If a gap is created between edges:
Loosen (rotate counter-clockwise) the cutter
adjustment nut to apply more contact
pressure between the reel cutter (cutting
cylinder) and the bed knife (bottom blade).
If the reel cutter (cutting cylinder) is too tight
to turn:
Tighten (rotate clockwise) the cutter
adjustment nut to reduce the contact
pressure between the reel cutter (cutting
cylinder) and the bed knife (bottom blade).
If the sharpness is not improved by the
adjustment:
Perform back lapping to the reel cutter
(cutting cylinder).
