Reelmaster 3100−D Page 7 − 7 Cutting Units
Adjustments
CAUTION
Never install or work on the cutting units or lift
arms with the engine running. Always stop en-
gine and remove key first.
Characteristics
The single knob bedknife−to−reel adjustment system in-
corporated in this cutting unit simplifies the adjustment
procedure needed to deliver optimum mowing perfor-
mance. The precise adjustment possible with the single
knob/bedbar design gives the necessary control to pro-
vide a continual self−sharpening action. This feature
maintains sharp cutting edges, assures good quality−
of−cut, and greatly reduces the need for routine back-
lapping.
In addition, the rear roller positioning system permits op-
timum bedknife attitude and location for varying height−
of−cuts and turf conditions.
If a cutting unit is expected to be out of adjustment, use
the following procedures in the specified order to adjust
the cutting unit properly.
1. Adjust the bedknife parallel to the reel.
2. Adjust the front roller.
3. Level the rear roller.
4. Set height−of−cut.
Daily Adjustments
Prior to each day’s mowing, or as required, each cutting
unit must be checked to verify proper bedknife−to−reel
contact. This must be performed even though quali-
ty of cut is acceptable.
1. Lower cutting units onto a hard, level surface. Shut
off engine and remove key from ignition.
2. Slowly rotate reel in the reverse direction while lis-
tening for reel−to−bedknife contact. If no contact is evi-
dent, turn bedknife adjusting knob clockwise, one click
at a time, until light contact is felt and heard.
3. If excessive contact is felt, turn bedknife adjusting
knob counterclockwise, one click at a time until no con-
tact is evident. Then turn bedknife adjusting knob one
click at a time clockwise, until light contact is felt and
heard.
IMPORTANT: Light contact is preferred at all times.
If light contact is not maintained, bedknife and reel
edges will not sufficiently self−sharpen and dull cut-
ting edges will result after a period of operation. If
excessive contact is maintained, bedknife and reel
wear will be accelerated, 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 for the full length of the bedknife. Running
a file occasionally across the front edge to remove this
burr will improved cutting quality.
After extended running, a ridge will eventually develop
at both ends of the bedknife. These ridges must be
rounded off or filed flush with cutting edge of bedknife to
assure smooth operation.
