Fundamentals of Reel Mowers

Set-up and Adjustments
Reel mower performance depends on proper set–up and adjustment procedures. An error of .010 inch or
.25 mm, in height end–to–end, or from one cutting unit to another, is visible as a mismatch on many golf
course greens. Although there are design variations in cutting units, most require the same basic
procedures. A surface plate, accurate height of cut tools and proper instruction are essential for setting up
a cutting unit.
There are many factors that can affect quality
of cut, including condition of the mowing
Factors that affect quality of cut
equipment and agronomic factors. Turf
conditions such as excessive thatch,

Tire pressure

Correct bedknife
Engine governed speed
Cutting unit alignment
and ground following
“sponginess” or attempting to cut off too much
grass height may not always be overcome by
adjusting the machine. It is important to
remember that the lower the height of cut, the
more critical these factors are.

Remember that the “effective” or actual height
of cut depends on cutting unit weight, cutting
unit accessories and turf conditions. Effective
height of cut will be different than the bench
set height of cut.

Height of cut (bench set
vs. actual)
Effective height of cut is the actual height the
grass has been cut. Making an accurate height
measurement on the turf is difficult due to
many variables. A true base is simply not
present. If the surface is uneven, spongy or
varies in density, color variations in the turf
may appear in the form of a streak. This is due
to the effective height of cut being too low for
the existing turf conditions. To correct
problems, start or change a cultural practice,
change cutting unit configuration or raise the
bench set height of cut. The lower your height
of cut, the more predictable and smooth the
turf surface must be.
