Revision A
4.9.4 Adjusting Conditioner Roll Tension
The conditioner roll tension is maintained by two tension springs providing adequate pressure for correct conditioning of
the crop. These springs also allow the rolls to open to allow passage of small solid objects without damage to the rolls.
DANGER
To avoid bodily injury or death from unexpected start-up or fall of a raised machine, always stop engine and remove
key before leaving the operator

counterclockwise to decrease tension.
6. Adjust nuts (B) on both sides equal amounts.
7. Tighten jam nuts (A).
4.9.5 Forming Shields
The position of the forming shields controls the width and placement of the windrow. The decision on forming shield
position (settings between 915 and 2346 mm [36 and 92 in.]) should be based on the following factors:
•
Weather conditions (rain, sun, humidity, wind)
•
Type and yield of crop
•
Drying time available
•
Method of processing (bales, silage, green-feed)
A wider windrow will generally dry faster and more evenly, resulting in less protein loss. Fast drying is especially important
in areas where the weather allows only a few days to cut and bale.
Where weather conditions permit or when drying is not critical (for example, when cutting for silage or green-feed), a
narrower windrow may be preferred for ease of pick-up.
