By following the blade path through two "clips"
as the machine moves forward we can
illustrate the actual process of cutting grass.
The bedknife pushes grass toward the shear
point while the reel blade gathers it in front.
Each blade path has one-half clip in which to
cut all the grass
Note that the grass outside of the forward half
clip is not easily gathered. The general rule of
thumb concerning height of cut vs. clip is that
both measurements should be within 20% of
each other. The best results will be obtained
when height of cut is equal to or close to the
clip.
Grass extending beyond the forward half clip,
yet tall enough to be within the blade path is
less likely to be cut. Reel blades may contact
the grass in this area several times prior to the
actual gathering of the grass. This is the so
called "fanning" process. This process is more
a mechanical striking of the grass that it is of
the commonly thought effect of a blowing
action.
