Model Year 2017
Original Instruction

This instruction contains the setup procedures, operation instructions, and parts lists for the MacDon Double
Windrow Attachment (DWA) for M1-Series Self-Propelled Windrowers.
Published: September 2016

Introduction
The Double Windrow Attachment (DWA) provides the ability to place two windrows of conditioned material close
together to be picked up by a forage chopper. The DWA can be mounted on the following MacDon Self-Propelled
Windrowers:
• M1240
The DWA is for use with the following headers:
• A-Series Auger Headers
• R-Series Rotary Disc Header
When the DWA system is engaged, the conditioned crop is deposited onto the side draper and placed to the side
of the windrower. Raising the side delivery disengages the DWA, allowing the crop to be deposited between the
windrower’s wheels.
When setting up the machine or making adjustments, review and follow the recommended machine settings in all
relevant MacDon publications. Failure to do so may compromise machine function and machine life and may result
in a hazardous situation.
MacDon provides warranty for Customers who operate and maintain their equipment as described in this manual.
A copy of the MacDon Industries Limited Warranty Policy, which explains this warranty, should have been provided
to you by your Dealer. Damage resulting from any of the following conditions will void the warranty:

kept clean and in good condition.
• Replace any worn, cut, abraded, flattened, or crimped
hoses and steel lines.
•DoNOT attempt any makeshift repairs to hydraulic
lines, fittings, or hosesby using tapes, clamps, cements,
or welding. The hydraulic system operates under
extremely high pressure. Makeshift repairs will fail
suddenly and create hazardous and unsafe conditions.
Figure 1.11: Testing for Hydraulic Leaks
•Wearprop
er hand and eye protection when searching
for high-pressure hydraulic leaks. Use a piece of
cardboard as a backstop instead of hands to isolate
and identify a leak.
•Ifinjur
ed by a concentrated high-pressure stream of
hydraulic fluid, seek medical attention immediately.
Serious infection or toxic reaction can develop from
hydraulic fluid piercing the skin.
