Roll Tension
Roll tension (the pressure holding the conditioner rolls together) is factory-set to maximum and should rarely require
adjustment.
Heavy crops or tough forage can cause the rolls to separate; therefore, maximum roll tension is required to ensure that
materials are sufficiently crimped.
Adjusting Roll Tension
To adjust roll tension, follow these steps:

Adjust spring drawbolt as follows:
•
Turn spring drawbolt (B) clockwise to tighten spring and
INCREASE
the roll tension.
•
