With the adjustment nut, adjust the
engagement between the reel cutter (cutting
cylinder) and the bed knife (bottom blade) so
that newspaper (two to three sheets) will be
cut by the edge of both blades when the
blades in their entirety come slightly into
contact with each other.

3.
Insert two or three strips 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)
by hand to check the sharpness of the
blades.
Check the sharpness of the entire range (at
three or four points between the left and right
ends) of the reel cutter (cutting cylinder).
If there is a gap between the blade edges:
Loosen the 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 the adjustment nut to reduce the
contact pressure between the reel cutter
(cutting cylinder) and the bed knife
(bottom blade).
If the blades still cannot cut well:
Perform back lapping of the reel cutter
(cutting cylinder).
