7 - 6 Service Dealer’s Guide to Great Quality of Cut
Appendices
Uncut grass—grass left standing after a mower has
passed over it. This usually refers to grass that is not
cut at all, as opposed to grass cut longer than the
mower’s height of cut setting should leave. This term
can also refer to an area of grass that has not been cut
or passed over by a mower.

Unlevel cut—a cut path with an inconsistent height of
cut.
Wet grass—grass that is wet to the touch. Rain,
watering, or morning dew can be the source of the
moisture.
Windrow—poor disbursement of clippings resulting in
a nearly continuous line of cut grass clippings on the
grass. This may also appear as clumps of dry grass,
generally in a row across the lawn.

1/3 Rule—a recommendation by turf grass
agronomists that not more than 1/3 of the height of the
grass be removed at one time to maintain the health of
grass plants. Most rotary mowers designed for urban
and suburban lawns are designed to work best when
operators follow this rule.
