3.6.14 Positioning the Forming Shields
WARNING
Keep hands and feet away from discharge opening. Keep everyone several hundred feet away from your
operation. Never direct the discharge toward anyone. Stones or other foreign objects can be ejected
with force.
The position of the forming shields controls the width and placement of the windrow. The decision on forming shield
position (settings between 915
–
2346 mm [36
–
92 in.]) should be made based on the following factors:
•
Weather conditions (rain, sun, humidity, wind)
•
Type and yield of crop
•
Drying time available
•
Method of processing (green feed, bales, silage)
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. Refer to
3.12 Haying, page 97 for
more information.
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.
Positioning Side Deflectors
The position of the side forming shields controls the width and placement of the windrow.
CAUTION
To prevent accidental movement of windrower, return ground speed lever (GSL) to Park, center steering
wheel to lock, shut off engine, and remove key.
To ensure windrow placement is centered with respect to carrier/drive wheels, adjust both side deflectors to the
same hole position on the adjuster bar.
