Height-of-Cut Chart Terms

Height-of-Cut Setting (HOC)
This is the desired height of cut.
Bench-Set Height of Cut
The bench-set height of cut is the height at which the top
edge of the bedknife is set above a flat level surface that
contacts the bottom of both the front and rear roller.
Effective Height of Cut
This is the actual height to which the grass has been cut. For
a given bench-set height of cut, the actual height of cut will
vary depending on the type of grass, time of year, turf, and
soil conditions. The cutting-unit setup (aggressiveness of cut,
rollers, bedknives, attachments installed, turf compensation
settings, etc.) will also affect the effective height of cut. Check
the effective height of cut using the Turf Evaluator (Model
04399) regularly to determine the desired bench-set height
of cut.
Aggressiveness of Cut
Aggressiveness of cut refers to the angle of the bedknife
relative to the ground (Figure
The best cutting-unit setup depends on your turf conditions
and desired results. Experience with the cutting unit on your
turf will determine the best setting to use. You can adjust the
aggressiveness of cut throughout the cutting season to allow
for various turf conditions.
In general, less to normal aggressive settings are more
appropriate for warm season grasses (Bermuda, Paspalum,
Zoysia) while cool season grasses (Bent, Bluegrass, Rye) may
require normal to more aggressive setups. More aggressive
setups cut more grass off by allowing the spinning reel to pull
more grass up into the bedknife.

2. Side-plate mounting flange
Rear Spacers
The number of rear spacers determines the aggressiveness
of cut for the cutting unit. For a given height of cut, adding
spacers, below the side plate mounting flange, increases the
aggressiveness of the cutting unit. All cutting units on a
given machine must be set to the same aggressiveness of cut
(Number of rear spacers, part no. 119–0626), otherwise the
after-cut appearance could be negatively affected
