IMPORTANT: Repeat the procedure on each end
of the bedknife and tighten locknuts that retain
rear roller brackets on each end.
CUTTING UNIT
CHARACTERISTICS
The single-knob bedknife-to-reel adjustment system
incorporated in this cutting unit simplifies the adjust-
ment procedure needed to deliver optimum mowing
performance. The precise adjustment possible with the
single knob/bedbar design gives the necessary control
to provide a continual self-sharpening action, thus
maintaining sharp cutting edges, assuring good quality
of cut, and greatly reducing the need for routine back-
lapping.
CUTTING UNIT DAILY
ADJUSTMENTS
Prior to each day's mowing, or as required, each cut-
ting unit must be checked to verify proper bedknife-to-
reel contact. This must be performed even though
quality of cut is acceptable.
1.
Lower the cutting units onto a hard surface, shut
of the engine and remove the key from the igni-
tion.
2.
Slowly rotate the reel in reverse direction, listen-
ing for reel-to-bedknife contact. If no contact is
evident, turn the bedknife adjusting knob clock-
wise, one click at a time, until light contact is felt
and heard.
3.
If excessive contact is felt, turn the bedknife
adjusting knob counterclockwise, one click at a
time until no contact is evident. Then turn the
bedknife adjusting knob one click at a time clock-
wise,until light contact is felt and heard.
IMPORTANT: Light contact is preferred at all
times. If light contact is not maintained, bedknife /
reel edges will not sufficiently self-sharpen and dull
cutting edges will result after a period of operation.
If excessive contact is maintained, bedknife/reel
wear will accelerate, uneven wear can result, and
quality of cut may be adversely affected.
Note: As the reel blades continue to run against the
bedknife, a slight burr will appear on the front cutting
edge surface the full length of the bedknife. Running a
file across the front edge to remove this burr will
improve cutting.
After extended running, a ridge will eventually devel-
op at both ends of the bedknife. These notches must be
rounded off or filed flush with the cutting edge of the
bedknife to assure smooth operation.
