Behind Center Distance (BCD) has a
positive correlation to Bedknife Angle
At seven degrees the behind center distance is even
greater.
Increasing the behind center distance results in a
more aggressive blade path.
Attitude
•Bedknife angle is extreme
•The bedknife is further from the
centerline of the reel
•The reel blades approach is from an
aggressive angle
The result can be a crisp, clean cut,
however; differences in up and back
appearance, a stripe, is pronounced.
The down side of this aggressive setting
is that any variation in reflections can be
very noticeable and perhaps undesirable.
An aggressive setting is:
An aggressive setting means the bedknife angle is
extreme. The bedknife is further from the centerline
of the reel and the reel blades approach is from an
aggressive angle.
The result can be a crisp, clean cut, however;
differences in up and back appearance, a stripe, is
pronounced. The down side of this aggressive
setting is that any variation in reflections can be very
noticeable and perhaps undesirable.
Attitude
•The angle of the bedknife is flat
•The bedknife is closer to the centerline
of the reel
•The reel blade approaches from a
horizontal direction
The result: A diffused appearance.
Reflective variations cannot be seen as
readily. The stripe is less defined. Cut is
prone to stragglers.
A flat setting (less aggressive) is:
With a reduction in behind center distance, the reel
does not gather grass as cleanly; therefore the grass
blades can be different lengths.
This is by definition stragglers, however; the
difference can be negligible and tends to diffuse the
reflective qualities of the cut grass thereby masking
imperfections
