Height-of-Cut Chart Terms

Height-of-Cut Setting (HOC)
This corresponds to the desired height of cut.
Bench-Set Height of Cut
This 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 rollers.
Effective Height of Cut
This is the actual height 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
The aggressiveness of cut has a significant impact on
the performance of the cutting unit. Aggressiveness
of cut refers to the angle of the bedknife relative to the
g006510
ground (Figure
The best cutting unit setup is dependent on your
turf conditions and desired results. Experience with
the cutting unit on your turf will determine the best
setting to use. Aggressiveness of cut may be adjusted
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.
