The basic groups of ground contacting rollers are
shown here.
Full Rollers
(Also referred to as solid rollers)
Full rollers provide a stable platform using full width
contact. Some characteristics of full rollers include:
Increases, the effective cutting height.
Rides higher or floats more on the turf.
Can be made heavier or larger to help with cutting
unit control.
Less likely to scuff the turf in turns.
Less likely to damage the turf when lowering onto it.
Narrower rear rollers can help address overlap roller
marks in cool season grasses. Note that the
narrower rollers can reduce the stability of the
cutting unit.
Wiehle Rollers
Wiehle (or grooved) rollers also provide a stable
platform with some different characteristics.
Contact line is broken into individual contact points
allowing for greater surface pressure at the contact
point.
Individual contact points allow for better incursion
into the turf canopy.
Allows seed heads to be cut and gathered better.
Note that these rollers can sometimes scuff the turf
in turns.
