OPERATION
HAY CONDITIONER FORMING SHIELDS
CAUTION: Keep forming shields installed at all times conditioner is in use. Do not allow
anyone to stand behind the machine while operating. Stones or other foreign objects may be
ejected from the conditioner with considerable force.
The side and rear deflectors, and deflector fins are adjustable to shape the windrow to your preference.
In deciding on windrow width, the following factors should be considered:
• 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. 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.
Windrow Width
Position the adjuster handle as required to move
the side deflectors to the desired width.
NOTE: With hardware installed in hole (A) in L/H
link as shown, deflectors will move symmetrically
about the center of the conditioner rolls. For the
most evenly formed windrows, use position (A)
for windrows up to 65 inches wide. Use hole (B)
only when windrows over 65 inches are required,
as this allows the left deflector to open to a wider
position than the right deflector. Maximum width
is with hardware in hole (B) and handle in
position (1).
Rear Deflector
The rear deflector (L) slows the crop exiting the
conditioner rolls, directs the flow downward,
and "fluffs" the material.
To start, adjust rear deflector to approximately
the mid-range position (45
°). Optimum position
for best windrow uniformity must be determined
for each crop condition.
To adjust rear deflector, loosen adjuster handles
(M), one per side, position deflector and tighten
adjuster handles (M). For even windrow formation,
be sure deflector is not twisted.
