Roll Tension - MacDon R85 Operator's Manual

6.10.3 Roll Tension

The roll tension (the force holding the rolls
together) is factory set to maximum and is
adjustable. Heavy crops or tough forage that
tend to separate the rolls require the maximum
roll tension to ensure that material is sufficiently
crimped. Light alfalfa and short grasses would
require less roll tension to lessen over-
conditioning.
