Roll Tension
Roll tension refers to the tension holding the rolls together. It is factory-set to maximum and should rarely require
adjustment. Heavy crops or tough forage can, however, cause the rolls to separate. In such conditions, maximum roll
tension is required to ensure that the cut crop is crimped sufficiently.
Adjusting Roll Tension
The amount of pressure that is applied to the crop as it passes through the roll conditioner is adjusted by changing the roll
tension setting. Generally, maximum roll tension is desirable.
DANGER
To avoid bodily injury or death from unexpected startup of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
’
s seat for any reason.
DANGER
Ensure that all bystanders have cleared the area.
To adjust the roll tension back to factory setting, follow these steps:

3.
Loosen jam nut (A) on both sides of the conditioner.
4.
Turn spring drawbolt (B) clockwise to tighten spring (C) and
increase the roll tension.
5.
Turn spring drawbolt (B) counterclockwise to loosen
spring (C) and decrease the roll tension.
6.
Measure the amount of exposed thread on spring
drawbolt (B) at each end of the conditioner.
Measurement (D) should be 12
–
15 mm (1/2
–
9/16 in.).
IMPORTANT:
Turn each bolt equally. Each turn of the bolt changes the
roll tension by approximately 32 N (7.2 lbf).
7.
Tighten jam nuts (A) on each end of the conditioner.
