12 QUALITY OF CUT
12.3 STEP CUTTING _____________________________________________________
NOTE: Arrow indicates direction of travel.
Step cutting occurs when the grass is cut higher on
one side of a reel than the other side. Step cutting
can occur when one cutting unit is higher than anoth-
er cutting unit.
The wear of mechanical parts or an incorrect roller
or height-of-cut adjustment can cause step cutting.
Possible Cause Solution
HOC (height-of-cut) settings are different from one
side of a reel to the other side or from one cutting unit
to another unit.
Check the HOC (height-of-cut) of the cutting units.
The front roller bearings are worn. Check and replace front roller bearings.
Reel-to-bedknife contact is different from one side of
the cutting unit to the other side, or from one cutting
unit to another side.
Check the contact between the reel and the bed-
knife.
The cutting reel can not rotate at full speed. Check and remove the cutting reel movement ob-
struction.
Differences in turf density. Change the direction of cut.
Machine weight distribution is not equal. Check and adjust the tyre pressures.
