Fundamentals of Reel Mowers
The cutting unit attitude is the angle between
the bottom of the bedknife and the ground
plane under the cutting unit. As the bedknife
attitude is changed, it is important to note that
the reel to bedknife shear point changes
relative to the center line of the reel. This can
change the after cut appearance of the grass.
The result may be better or worse depending
on several factors.
Bedknife attitude is adjusted by changing the
height of the front, rear, or both rollers. A
height of cut change is NOT necessarily part of
a change to the bedknife attitude. A large
angle is also referred to as an aggressive
bedknife attitude. A small angle (flat attitude)
can have most or all of the bedknife riding ON
the turf. This can influence after cut
appearance.
It will normally be an advantage to have the
front or the cutting edge of the bedknife lower
than the back. This help prevent the bedbar
from contacting the ground surface in very low
heights of cut. It will also prevent the streaking
or ruffling of the turf after it has been cut and
passed over by the bedbar.
There is a limit on how much of a forward
angle the bedbar can be positioned to. If the
rear is positioned too high the reel position can
become lower than the cutting edge, tearing
the grass and giving a poor quality of cut.
To achieve an acceptable quality of cut the
rollers must be parallel to the reel. Before
adjusting roller parallelism, check for loose
roller bearings. Adjust or replace the bearings
as necessary. First parallel the front or rear
roller, which ever is NOT used for setting the
height of cut. This paralleling roller is set to
match the reel using a surface plate fixture.
With the reel blades resting on a raised bar on
the plate, use a piece of paper as a feeler
gauge along the bottom of the roller between
the roller and plate.
