12.2 WASHBOARDING _________________________________________________________
NOTE: Arrow indicates direction of travel.
Washboarding is a repeated pattern of different cutting
heights, that causes an appearance that is like a wave. In
most cases, the wave tip-to-tip distance is approximately
6—8 in. (15—20 cm). A change in the color (from light-to-
dark) is also seen.
This cause of this condition can be a movement from side
-to-side in the cutting units (s). This condition is found on
mowers with cutting units held under the mower, but other
cause can give the same result.
Another cause of Washboarding is differences in the type
of turf.
Probable Cause Remedy
The cut (ground) speed is higher than normal. Reduce the cut (ground) speed.
Grass attaches on roller. Clean the roller and scraper.
The roller is out of round. Replace the roller.
Cut in the same direction. Change the direction of cut more frequently.
Cutting units have too much or too little weight on
them.
Use traction control switch to transfer weight on or off
cutting units.
Not enough engine speed, engine speed is not set to
specification.
Check/adjust the engine speed.
Hydraulic system and deck drive motor performance is
decreased.
Check the hydraulic system performance (pump output,
motor operation, valve operation and relief valve
settings).
