Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Cutting Unit Characteristics
The single knob bedknife-to-reel adjustment system
incorporated in this cutting unit simplifies the adjustment
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
backlapping.
In addition, the rear roller positioning system permits
optimum bedknife attitude and location for varying
height-of-cuts and turf conditions.
Cutting Unit Daily Adjustments
Prior to mowing each day, or as required, each cutting unit
must be checked to verify proper bedknife–to–reel
contact. This must be performed even though quality of
cut is acceptable.
1. Lower cutting units onto a hard surface, shut off
engine and remove key from ignition.
2. Slowly rotate reel in 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
contact 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/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 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 the full length of the bedknife. If a file is
occasionally 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 cutting edge of bedknife to ensure
smooth operation.
