11.2 Quality of Cut Troubleshooting
It is recommended that a "test cut" be performed to evaluate the mower's performance before beginning
repairs.
An area should be available where "test cuts" can be made. This area should provide known and consistent
turf conditions to allow accurate evaluation of the mower's performance.
Another "test cut" should be performed after the completion of the repairs and/or adjustments to verify the
mower's performance.
Before performing a "test cut" to diagnose cut appearance and mower performance, the following items
should be verified to ensure an accurate "test cut."
1.
Mowing (Ground) Speed
2.
Blade Sharpness
3.
Height-of-Cut (HOC)
4.
Roller and Roller Bearing Condition
5.
Blade Speed

SAFETY, OPERATORS & MAINTENANCE MANUAL
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). Color 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.Washboarding
may also be caused by variations in the turf.
