OPERATING VARIABLES (continued)
8. 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.
A baffle inside the forming shields controls the degree to which they narrow the discharge of cut material. The
decision to lay a full width swath or narrow windrow (or one of the five intermediate widths) 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 wide swath 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. See "Haying Tips" in this section
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.
To adjust material discharge width:
a. Pull spring-loaded pin (A) out of adjustment
hole.
b. Raise or lower handle (B). Handle fully up (as
shown) raises baffle (C) completely, producing
the narrowest windrow. Handle fully down
lowers baffle completely, producing the widest
swath. There are five intermediate positions.
c. Release pin (A) into desired adjustment hole.
Light crop deflectors
Deflectors (D) are only required when windrowing
light crop to aid in proper windrow formation. In
relatively heavy crops, the deflectors may cause
bunching at the sides of the windrow.
