12 QUALITY OF CUT

12.5 SCALPING _______________________________________________________________

NOTE: Arrow indicates direction of travel.

Scalping is a condition in which areas of grass are cut
shorter than the adjacent areas. The area can be light
green or brown. A low HOC setting or turf that is not level
can cause scalping.

Probable Cause

Remedy

HOC (height-of-cut) settings are lower than normal.

Check and adjust the HOC settings.

The reel-to-bedknife adjustment is different from one
side of a cutting unit to the other side or from one
cutting unit to another unit

Check the reel-to-bedknife adjustment.

Turf is not level and the mower can not follow the turf.

Change the direction of cut.

Grass is higher than the cutting unit capacity.

Cut the grass more frequently.

Cut (ground) speed is higher than the mower can cut.

Reduce the cut (ground) speed.
