Windrow Width Adjustment
Center Baffle Position
For narrower windrows, the
center baffle is usually in
full up position.
Handle can be lowered 1 or
2 notches to prevent crop
from being projected above
the forming shield top
cover.
Position the center baffle all
the way down to obtain
maximum swath width.
Remove the hair pin that
secures the strap to the
windrower.
Lower or raise shield to
the desired height.
Re-insert the hair pin.
Generally, the fourth hole
from the top of the strap
(shown) provides a good
starting position for most
crops.
Lower rear of the forming
shield if the crop is not
hitting the top cover.
When using DWA, use
the highest forming shield
position.
Forming Shield Rear Height Adjustment
Inner Deflecting Fins
Fins are bolted underneath
the forming shield.
Fins aid in distributing crop
material evenly throughout
the windrow.
Removing or adding fins
will change crop flow. Each
fin can be mounted in three
alternative positions.
Position fins to obtain even
crop distribution across full
width of the windrow/swath.
Remove the lynch pin.
Move arm into the desired
position. Re-insert the
lynch pin.
For narrow windrow, use
holes closest to the header.
For wider windrow, use
holes furthest away from
the header.
Mount forming shield front
support bolt in the upper
hole in the tractor lift
linkage.
For smoother windrows in
lighter crops, the lower
hole in the lift linkage may
be used so that the crop
flow engages the forming
shield closer to the front
edge.
When using the DWA
attachment, the front of the
forming shield must be
mounted to the upper hole
in the lift linkage.
Forming Shield Front Mounting Point
Rear Baffle Fluffer Adjustment
Loosen handle (shown), and
raise or lower baffle to
adjust the angle.
Tighten handle to lock its
position (NOTE: This must
be done on both sides).
A greater angle (i.e., baffle
pointed down) will allow for
“fluffy” windrows.
An excessively steep baffle
angle may cause an uneven
windrow.
When using DWA, position
the rear baffle in the highest
position. (NOTE: It may be
necessary to lower the LH
side to direct crop onto the
DWA belt).
