QUALITY OF CUT

5.1

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.

WASHBOARDING__________________________________________________________

NOTE: Arrow indicates direction of travel.
Probable Cause
Decks have too much or too little weight on them.
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. Decks Leveled
5. Blade Speed
6. Deck Rake not Set
Washboarding is a cyclical pattern of varying cutting
heights, resulting in a wave-like cut appearance.
This condition is usually caused by the weight transfer not
set correctly.
Washboarding may also be caused by variations in the
turf.
