INTRODUCTION
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.

to the linkage clevis (N). Make sure there is
a loose bushing inside the deck pivot.
7. Align the deck pivot with holes in clevis by
rising or lowering the floor jack and insert
shaft (P). At bottom install one regular hex
nut (H) and torque the nut to 250 ft-lbf. Then
install lock nut (G) and tighten against nut

IMPORTANT: Nuts need to have the proper
torque applied. Add grease to grease

9. Adjust turnbuckle (Q) length so the deck is
approximately 4 in. (100 mm) from the right
hand drive tire. The turnbuckle length should
be about 21 in. (530 mm) long for the RSeries Disc Header and 25 in. (630 mm)
long for the A-Series Auger or D-Series
Draper Headers.
NOTE: The lift cylinder is single acting and it
is pressurized with the draper drive circuit.
Therefore when the deck is setup for the RSeries Disc Header the windrower needs to
be running for the deck to be in its most
forward position. This adjustment can be
fine-tuned when the hydraulics setup is
complete.
