Another term known as "the cutting path" is the
result of the helix angle and the forward motion
of the cutting unit. The shear point moves
down the bedknife as the bedknife moves
forward. The grass is physically cut at an angle
to the bedknife.
Other factors which affect reel mowing are the
grass density and the grass acclimation or
grain. Grass tends to thicken at the normal
maintained height of cut. The denser the
grass, the easier it is for the bedknife and reel
to gather it. Grass density and grain can often
override other factors we have discussed
regarding the cutting action.

The basic requirements for good performance
of reel mowers are:
These requirements will be discussed in more
detail later.
•
The cutting edges on the reel blades
and bedknife must be straight and
sharp.
•
The bedknife must be exactly parallel
with the reel.
•
The bedknife should be positioned
against the reel with light contact.
