OPERATION
4.9.4 Adjusting Conditioner Roll Tension
The conditioner roll tension is maintained by two tension springs to provide 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.
1. Locate the adjustment nuts on top of the conditioner
channel.
2. Loosen jam nuts (A).
3. Turn adjusting nut (B) clockwise to increase tension,
and counterclockwise to decrease tension.
4. Adjust nuts (B) on both sides equal amounts.
5. Tighten jam nut (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 36 and 92 inches [915 and 2346 mm]) 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 pickup.
