OPERATING THE HEADER
4.3 Roll Tension
Roll tension (the force holding the rolls together) is factory set with a spring type adjustable linkage.
The roll tension factory setting is the spring fully tensioned.
Heavy crops or tough forage tend to separate the rolls and require more tension to ensure material is suf fi ciently
crimped. Light alfalfa and short grasses require less tension to minimize over-conditioning.
4.3.1 Adjusting Roll Tension
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.
1. Lower the header fully.
2. Stop the engine and remove the key.
3. Open the driveshield. Refer to
3.4 Driveshields, page 28
.
4. To decrease the roll tension, turn the spring drawbolts counterclockwise to loosen the springs.
5. To increase the roll tension, loosen jam nut (A) and turn
the spring drawbolt (B) clockwise to tighten the spring
at each end of the roll. Spring is fully tensioned at the
factory.
IMPORTANT:
Turn each bolt equal amounts. Each turn of the
bolt changes the roll tension by approximately
44.5 N (10 lbf).
6. Tighten jam nut (A) against casting after
adjusting tension.
7. Close the driveshield. Refer to
3.4 Driveshields, page
28
