Forming Shields; Side Deflectors - MacDon A30-S Operator's Manual

6.17.13 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 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.
Refer to Section 6.18, Haying Tips, 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.

adjuster bar. To achieve this setting, adjuster
bars must be in the corresponding hole both
