Height-of-Cut Chart Terms

Height of Cut Setting (HOC)
The desired Height of Cut
Bench Set Height of Cut
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 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 set up (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
Cutting unit 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 ground
(Figure 16).
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.

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. 106-3925), otherwise the
after-cut appearance could be negatively affected
Turf Compensation Settings
The turf compensation spring transfers the weight from the
front to the rear roller. (This helps to reduce a wave pattern
in the turf, also known as marcelling or bobbing.)
Important: Make spring adjustments with the cutting
unit mounted to the traction unit, pointing straight
ahead and lowered to the shop floor.
1. Make sure the hairpin cotter is installed in the rear hole
in the spring rod
Note: When servicing the cutting unit, move the
hairpin cotter to the spring rod hole next to the turf
compensation spring.

2. Tighten the hex nuts on the front end of the spring rod
until the compressed length of the spring is 15.9 cm
(6.25 inches) (Figure
Note: When operating on rough terrain decrease the spring
length by 1.27 cm (1/2 inch). Ground following will be
slightly decreased.
Note: The turf compensation setting will need to be reset
if the HOC setting or the Aggressiveness of Cut setting is
changed.
Note: If the cutting unit must be removed from the machine,
move the hairpin cotter to the front hole in the spring rod
(Figure 17). Make sure to move the hair pin cotter back to the
rear hole in the spring rod after the cutting unit is reinstalled
to the machine.
