Adjustments
Daily Adjustments (Single Point Adjust Cutting Units)
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 surface, shut off en-
gine, and remove the key from the ignition switch.
2. Slowly rotate reel in the reverse direction listening
for reel−to−bedknife contact. If no contact is evident,
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 clock-
wise, one click at a time, until light contact is felt and
heard.
IMPORTANT: Light bedknife−to−reel contact is pre-
ferred at all times. If light contact is not maintained,
bedknife and reel edges will not sufficiently self−
sharpen, and dull cutting edges will result after a pe-
riod of operation. Excessive contact can cause
accelerated and/or uneven bedknife and reel wear.
Thus, 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. If a file
is occasionally run across the front edge to remove this
burr, quality of cut will improve. If this burr is not re-
moved, the quality of cut will appear as if it was cut with
a dull reel (grass will appear torn or ripped).
After extended running, a ridge will eventually develop
at both ends of the bedknife. These ridges must be
rounded off or filed flush with the cutting edge of the bed-
knife to assure smooth operation.
Daily Adjustments (4−Bolt Adjust Cutting Units)
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 surface, shut off en-
gine, and remove the key from the ignition switch.
2. Slowly rotate reel in the reverse direction listening
for reel−to−bedknife contact. If no contact is evident, ad-
just bedknife to reel (see Bedknife to Reel Adjustment
(4−bolt Adjust Cutting Units)).
3. If excessive contact is felt, adjust bedknife (see
Bedknife to Reel Adjustment (4−bolt Adjust Cutting
Units)).
IMPORTANT: Light bedknife to reel contact is pre-
ferred at all times. If light contact is not maintained,
bedknife and reel edges will not sufficiently self−
sharpen, and dull cutting edges will result after a pe-
riod of operation. Excessive contact can cause
accelerated and/or uneven bedknife and reel wear.
Thus, 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. If a file is oc-
casionally run across the front edge to remove this burr,
improved cutting can be obtained.
After extended running, a ridge will eventually develop
at both ends of the bedknife. These notches must be
rounded off or filed flush with the cutting edge of the bed-
knife to assure smooth operation.
