3.10.2 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:
WARNING
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.
1. Lower the header to the ground.
2. Shut down the engine, and remove the key from the ignition.
Figure 3.60: Roll Tension Adjuster
3. Loosen jam nut (A) on both sides of the conditioner.
4. Adjust spring drawbolt as follows:
• Turn spring drawbolt (B) clockwise to tighten spring and
INCREASE the roll tension.
• Turn spring drawbolt (B) counterclockwise to loosen
spring and DECREASE the roll tension.
IMPORTANT:
Turn each bolt equally. Roll tension changes by
approximately 32 N (7.2 lbf) with each turn of the drawbolt.

5. Measure the amount of exposed thread on spring
drawbolt (A) at each end of the conditioner. For steel roll
conditioners, measurement (B) should be 12–15 mm
(1/2–9/16 in.).
6. Tighten jam nut (C) on both sides of the conditioner.
