Overlap Marks
Description:
An overlap area is defined as the area where cutting
units mow over the path of other cutting units causing
various color variations to appear. This is the result
of either individual cutting units within the path of a
machine or where the paths meet (up and back with
alternating directions). The grass is both rolled
and/or cut at least twice in this area and appearance
can be affected by either or both.

Causes of Overlap Marks:
•
•
Being cut twice resulting in indentations or marks of lighter color
Being rolled twice can create raised or darker marks, which generally dissipate within a few hours
after mowing
•
•
Excessive thatch or grain
Color variations in canopy (Small green leaves on longer stem can increase overlap mark
occurrence)
•
•
•
•
•
Cutting off too much grass at one time
Dull cutting units
Cutting out of clip range
Turf stresses due to weather conditions
Turf compensation system improperly set
Possible Corrective Actions:

TIP

Sharpen reel and bedknife
observing the cutting
Increase or decrease reel speed
coming toward you
versus moving away.
Always observe and
compare results while
looking at the same
direction of travel.
Adjust turf compensation system
Change mowing direction frequently
Adjust counterbalance of rear cutting units to be slightly different
