Streaks
Description:
Streaks appear as a line of taller grass that has not
been cut. Single, straight streaks are the result of a
bent or nicked bedknife. Multiple straight streaks
are more often the result of rifling due to heavy
contact between the reels and bedknife. Half-moon
Streaks may also appear as a result of turning or
side hill operation.
