The Double Windrow Attachment (DWA) allows the combining of two windrows of conditioned material
close together to be picked up by a forage chopper. This unit may be mounted on the following MacDonbuilt self-propelled windrowers: M150, M155, M200, and M205. The system is for use with A-Series Auger
Headers, R-Series Rotary Disc Headers, and D-Series Draper Headers with HC10 hay conditioners. The
conditioned crop is deposited onto the side delivery system draper and delivered to the side of the
windrower when required. Raising the side delivery system shuts off the draper and allows the crop to be
deposited between the windrower wheels as it would be witho ut the side delivery system.
NOTE: Depending on windrower model year, a software update may be requi red for proper function of
the auxiliary lift valve block provided with your DWA. Refer to Service Bulletin SB1210 for details.

SET-UP INSTRUCTIONS
NOTE: This unit fits only the windrower models listed in the Introduction. It cannot be installed on the
M100/M105 Self-Propelled Windrower models.
Rework required for pre-2008 windrowers
Before installing the DWA on a windrower built prior to production year 2008, follow these instructions:
1. If not present, drill four holes 0.781 in. (20 mm) diameter at the locations shown above. There are
hydraulic hoses above the two rear holes. Make sure hoses are out of the way when drilling.
Ream/grind rear holes to make them square for square neck bolts. Slots are only required if holes do
not line up with Double Windrow Attachment frame.

In the setup instructions, if you chose “NO” to
swap the DWA controls, use the ROCKER
switch installed in the console. Press the
ROCKER switch forward portion to lower the
DWA and press the ROCKER switch rearward
portion to raise the DWA.
To raise and lower deck
NOTE: Extra caution should be taken when
raising the deck for the first time. The deck
rotates as it raises and lowers and the
backsheet folds on to the deck. Make sure the
deck and backsheet are not interfering with any
windrower parts or the forming shield.
In the setup instructions, if you chose to swap
the DWA controls, use the REEL FORE/AFT
switch to raise and lower the deck. The deck
moves forward when lowering, so switch
operation will be the same as when moving the
reel forward. The deck moves rearward when
raising so switch operation will be the same as
when moving the reel rearward.
169216 Revision E
NOTE: Draper shuts off automatically when
deck is raised about two thirds of the way up. If
deck does not shut off soon enough, resulting in
backsheet touching draper before it shuts off,
the switch at the linkage needs to be lowered.

To adjust deck angle
The deck angle relative to the right hand drive
tire is adjustable with turnbuckle (Q). A distance
of 4 in. (100 mm) from the deck to the tire is
recommended. To adjust the turnbuckle, loosen
the locking tab and rotate center tube to desired
length then relock tab against tube.
NOTE: If setup with an R80 header, the deck
will only be in its most forward position when the
windrower is running. The lift cylinder is single
acting so it is not pressurized in the down stroke
when the windrower is shut off. When the
windrower is running there is a supply of low
pressure oil to move the deck forward.
The deck angle relative to the ground should be
horizontal or at a slight incline. Distance (C)
should be equal to or greater than (D). If used
with an R80 header in lighter crop, distance (C)
should be equal to (D). If the crop needs to be
thrown farther, increase distances (C).

To adjust deck height
The deck should never touch the ground or
excessive wear could occur to some deck
components. If the deck is too low to the ground,
raise it as follows:
• Lower linkage by fully extending cylinder.
• Move bottom pivot pin to lower position (R).
• This will raise the front of the deck
approximately 4 in. (100 mm).
Draper tracking
Draper tracking needs to be checked when the
draper is first run-up otherwise damage to the
draper can occur. See Draper Adjustment in the
Maintenance/Service section on how to adjust
the tracking.

OPERATION
Conditioner forming shield position
Make sure forming shield is high enough to clear
the deck when it is lowered (G). Adjust the
forming shield height by removing hair pin (J)
and moving strap (K) to desired position. The
forming shield should be as low as possible
without interfering with deck.

K
J
The left hand side deflector (L) should be in the
widest position to not affect crop flow. If center
delivering, the left hand deflector can be moved
in to make a narrower windrow. The right hand
side deflector should be in the widest position to
not affect the crop flow because this is where
the deck is the furthest from the conditioner rolls.
DECK RAISED
Fins (M) underneath the forming shield can
affect the crop flow. It is recommended to
remove fins, especially with an R80 in light crop.
Conditioner rolls position
The gap between the conditioner rolls needs to
be small enough to properly throw the crop on to
the double windrow attachment. The gap is
dependent on crop type and yield. If the gap is
too little for heavy crops, this consumes
excessive engine power and is hard on all the
components affected. If the gap is too large, the
crop will not have enough velocity to reach the
side delivery deck. See conditioner Operator’s
manual for adjustment procedure.
169216 Revision E

OPERATION
Operating recommendations
15, 16, 18, and 20 ft. Headers: On the first
pass, the side delivery system is raised and crop
is deposited between windrower wheels. On the
return pass, the side delivery system is lowered
and crop is deposited outside of the windrower
wheels to the right, beside the previously laid
windrow. Position of the crop can be adjusted by
using the side deflectors on the forming shields
when depositing the crop in the center and by
varying the draper speed when depositing the
crop to the side. The faster the draper speed is
set, the farther the crop will be delivered to
the side.
25 and 30 ft. Headers: The side delivery
system is lowered at all times. Crop is deposited
outside the windrower wheels and laid beside
the previously deposited windrow on return
pass. Position of the crop can be adjusted by
varying the draper speed when depositing the
crop to the side. One can also raise the side
delivery system and center deliver all the time.
Operating recommendations with R80 Rotary
Disc Header:
The conditioner rolls on an R80 Rotary Disc
Header are further ahead than all other headers;
therefore delivering light crop from the
conditioner rolls to the side delivery deck may
require special attention:
a. Rear baffle on the R80 header should
be in the upmost position. However it
may need to be lower for center
windrowing.
b. If there are fins on the rear baffle,
remove them to prevent interference
with the crop flow.
c. Header angle: The steeper the header
angle, the higher the arc of the crop
trajectory will be. Header angle should
be set such that the crop is projected at
a maximum arc height without excessive
contact with the top forming shield. It
may be possible to shoot crop above the
forming shield with extreme header
angle and rear baffle positions. In rocky
conditions where DWA is necessary, a
high skid shoe kit or adjustment to
gauge rollers may be required to
achieve correct stubble height and also
maintain crop trajectory.
d. Header height: affects the header angle.
Target should be to have the lift linkage
fully down at all times.
e. The roll gap should be small enough to
properly grab the crop and throw it.
f. The roll speed which is mechanically
tied to the disc speed can affect how
fast the crop gets projected. This again
should be in the recommended range.
There are three areas that can affect the crop
flow to the deck:
1. Crop flow from the cutterbar to the rolls.
a. Header cut width must be kept as full as
possible on the right hand side. Any less
than 75% may have adverse effects on
feeding.
b. Feed plates must be installed for
appropriate crop. They are required for
forage but not for alfalfa. (See R80
Operator’s Manual.)
c. Higher ground speeds will usually result
in better crop flow from the conditioner
rolls to the deck. Ground speed should
be a minimum of 6 mph (10 km/h) for
light crops.
d. Disc speed must be in recommended
range for specific crop/yield. (See R80
Operator’s Manual.)
2. Crop flow from rolls to forming shield.
169216 Revision E
3. Forming shield settings:
a. Make sure forming shield (B) is installed
correctly with bracket (A).
b. Buildup of sticky crop residue on
deflector sliding surfaces should be
periodically removed.
c. See “Conditioner Forming Shield
Position” on previous page.

MAINTENANCE/SERVICE
Draper Tension Adjustment
Draper tension should be just enough to prevent
slipping and keep draper from sagging.
Set draper tension as follows:
1. Check that draper guide (rubber track on
under- side of draper) is properly engaged in
groove of drive roller and that idler roller is
between the guides.
2. Turn bolt (A) clockwise (tighten) and white
indicator bar (B) will move to the right in
direction of arrow to indicate that draper is
tightening. Tighten until bar is about halfway
in window.
IMPORTANT: To avoid premature failure of
draper, draper rollers and/or tightened
components, do not operate with tension set
so that white bar is not visible.

Draper Tracking Adjustment
The draper deck has one fixed roller and one
spring-loaded roller. The spring loaded roller is
located at the same end of the deck as the
draper tensioner. Both rollers can be aligned by
adjuster rods.
If the draper is tracking incorrectly, make the
following adjustments to the rollers:
