for M-Series Self-Propelled
Windrowers
Setup, Operation, and Parts Manual
214049 Revision A
Model Year 2017
Original Instruction

This instruction contains the setup procedures, operation instructions, and parts lists for the MacDon Double
Windrow Attachment (DWA).
Published: October 2016

Introduction
The Double Windrow Attachment (DWA) provides the ability to place two windrows of conditioned material close
together.
The DWA can be mounted on M150, M155, M155E4, M200, and M205 Self-Propelled Windrowers.
The DWA is for use with A-Series Auger Headers, D-Series Draper Headers with HC10 Hay Conditioners, and
R-Series Rotary Disc Headers.
NOTE:
• A DWA should not be used on headers larger than 25 feet.
• The HC10 is not compatible with M205 Self-Propelled Windrowers.
• The HC10 is compatible with M100, M105, M150, M155, M155E4, and M200 Self-Propelled Windrowers. These
windrowers can use both a DWA and the HC10 on draper headers between 15 and 25 feet.
NOTE:
Depending on the windrower model year, a software update may be required for proper function of the auxiliary lift
valve block provided with your DWA. Refer to MacDon Service Bulletin #SB1210 for details.
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.

SAFETY
1.3 General Safety
CAUTION
The following are general farm safety precautions
that should be part of your operating procedure for
all types of machinery.
Protect yourself.
• When assembling, operating, and servicing machinery,
wear all protective clothing and personal safety devices
that could be necessary for job at hand. Do NOT take
chances. You may need the following:
• Hard hat
• Protective footwear with slip resistant soles
• Protective glasses or goggles
• Heavy gloves
• Wet weather gear
• Respirator or filter mask
Figure 1.2: Safety Equipment
• Be aware that exposure to loud noises can cause
hearing impairment or loss. Wear suitable hearing
protection devices such as ear muffs or ear plugs to
help protect against objectionable or loud noises.
Figure 1.3: Safety Equipment
•Provideafirst aid kit for use in case of emergencies.
• Keep a fire extinguisher on the machine. Be sure fire
extinguisher is properly maintained. Be familiar with its
proper use.
• Keep young children away from machinery at all times.
• Be aware that accidents often happen when Operator
istiredorinahurry.Taketimetoconsidersafestway.
Never ignore warning signs of fatigue.
Figure 1.4: Safety Equipment
214049 3Revision A

SAFETY
•Wearclose-fitting clothing and cover long hair. Never
wear dangling items such as scarves or bracelets.
• Keep all shields in place. NEVER alter or remove safety
equipment. Make sure driveline guards can rotate
independently of shaft and can telescope freely.
• Use only service and repair parts made or approved
by equipment manufacturer. Substituted parts may not
meet strength, design, or safety requirements.
Figure 1.5: Safety around Equipment
• Keep hands, feet, clothing, and hair away from moving
parts. NEVER attempt to clear obstructions or objects
from a machine while engine is running.
•DoNOT modify machine. Unauthorized modifications
may impair machine function and/or safety. It may also
shorten machine’s life.
• To avoid bodily injury or death from unexpected startup
of machine, ALWAYS stop engine and remove key from
ignition before leaving operator’s seat for any reason.
Figure 1.6: Safety around Equipment
• Keep service area clean and dry. Wet or oily floors are
slippery. Wet spots can be dangerous when working
with electrical equipment. Be sure all electrical outlets
and tools are properly grounded.
• Keep work area well lit.
• Keep machinery clean. Straw and chaff on a hot
engine is a fire hazard. Do NOT allow oil or grease to
accumulate on service platforms, ladders, or controls.
Clean machines before storage.
•NEVER use gasoline, naphtha, or any volatile material
for cleaning purposes. These materials may be toxic
and/or flammable.
• When storing machinery, cover sharp or extending
components to prevent injury from accidental contact. Figure 1.7: Safety around Equipment
214049 4Revision A

SAFETY
1.4 Maintenance Safety
To ensure your safety while maintaining machine:
• Review operator’s manual and all safety items before
operation and/or maintenance of machine.
• Place all controls inNeutral, stop engine, set parkbrake,
remove ignition key, and wait for all moving parts to stop
before servicing, adjusting, and/or repairing.
• Follow good shop practices:
– Keep service areas clean and dry
– Be sure electrical outlets and tools are
properly grounded
– Use adequate lighting for job at hand Figure 1.8: Safety around Equipment
• Relieve pressure from hydraulic circuits beforeservicing
and/or disconnecting machine.
• Make sure all components are tight and that steel lines,
hoses, and couplings are in good condition before
applying pressure to hydraulic systems.
• Keep hands, feet, clothing, and hair away from all
moving and/or rotating parts.
• Clear area of bystanders, especially children, when
carrying out any maintenance, repairs or, adjustments.
• Install transport lock or place safety stands under frame
before working under machine.
• If more than one person is servicing machine at
same time, be aware that rotating a driveline or other
mechanically-driven component by hand (for example,
accessing a lube fitting) will cause drive components in
other areas (belts, pulleys, and knives) to move. Stay
clear of driven components at all times.
Figure 1.9: Equipment NOT Safe for Children
• Wear protective gear when working on machine.
• Wear heavy gloves when working on knife components.
Figure 1.10: Safety Equipment
214049 5Revision A

SAFETY
1.5 Hydraulic Safety
• Always place all hydraulic controls in Neutral
before dismounting.
• Make sure that all components in hydraulic system are
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.
Figure 1.12: Hydraulic Pressure Hazard
• Make sure all components are tight and steel lines,
hoses, and couplings are in good condition before
applying pressure to a hydraulic system.

214049 6Revision A

SAFETY
1.6 Safety Signs
• Keep safety signs clean and legible at all times.
• Replace safety signs that are missing or
become illegible.
• If original parts on which a safety sign was installed
are replaced, be sure repair part also bears current
safety sign.
• Safety signs are available from your Dealer
Parts Department.
• Safety signs are available from your MacDon Dealer.

2 Assembly/Setup Instructions
NOTE:
The Double Windrow Attachment (DWA) will only fit windrower models listed in the Introduction ( Introduction,
page i). The DWA cannot be installed on the M100 or M105 Self-Propelled Windrower models.
2.1 Reworking Frame for Pre-2008 Windrowers
Before installing the Double Windrow Attachment (DWA) on a windrower built before the 2008 production year, follow
these instructions:
1. If holes are not present, drill four 20 mm (25/32 in.) diameter holes at the locations shown in Figures 2.1:
Rear-Facing Frame, page 11 and 2.2: Forward-Facing Frame, page 12.
IMPORTANT:
Move hydraulic hoses out of the way before drilling into the frame at the rear-facing end of the windrower.
2. Ream/grind rear holes to make them square for square neck bolts.
NOTE:
Slots are only required if holes do not line up with DWA frame.
