10.8 WASH BOARDING ____________________________________________________
NOTE: The Arrow indicates direction of travel.
Possible Cause
Mowing (ground) speed is too fast.
Grass build-up on roller.
Roller is out of round.
Mowing in the same direction.
Washboarding is a cyclical pattern of varying cutting
heights, resulting in a wave-like cut appearance. In
most cases, the wave tip-to-tip distance is
approximately 6—8 in. (15—20 cm). Colour
variation (light-to-dark) may also be noticed.
This condition is usually caused by a rocking motion
in the cutting unit(s). This condition is found mostly
on mowers with multiple (suspended) cutting units,
but other causes can produce the same result.
Washboarding may also be caused by variations in
the turf.
