The information in this publication is based on the information available and in effect at the time of printing. MacDon
Industries, Ltd. makes no representation or warranty of any kind, whether expressed or implied, with respect to the
information in this publication. MacDon Industries, Ltd. reserves the right to make changes at any time without notice.

Introduction
The Double Windrow Attachment (DWA) allows the windrower to place two windrows of conditioned material close
together. When the DWA system is engaged, the conditioned crop is deposited onto the side draper and placed to the right
side of the windrower. Raising the side delivery disengages the DWA, allowing the crop to be deposited between the
windrower’s wheels.
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 7.6 m (25 ft.).
•The HC10 is not compatible with M205 Self-Propelled Windrowers.
•M150, M155, M155E4, and M200 Self-Propelled Windrowers can use both a DWA and the HC10 on draper headers of
widths 4.6 - 7.6 m (15-25 ft.).
NOTE:
Depending on the windrower model year, a software update may be required to ensure the functionality of the auxiliary lift
valve block provided with your DWA. Refer to MacDon Service Bulletin #SB1210 for details.
Carefully read all the material provided in this manual before attempting to operate or maintain the DWA.
Contact your Dealer if you need assistance, information, or additional copies of this manual.
When setting up the machine or making adjustments to it, review and follow the recommended machine settings in all
relevant MacDon publications. Failure to do so may compromise the functionality and the service life of the machine 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:
•Accident
•Misuse
•Abuse
•Improper maintenance or neglect
•Abnormal or extraordinary use of the machine
•Failure to use the machine, equipment, component, or part in accordance with the manufacturer’s instructions
Conventions
The following conventions are used in this document:
•Right and left are determined from the operator’s position, facing forward with the windrower in cab-forward position.
•Unless otherwise noted, use the standard torque values provided in Chapter 6 Reference, page 109 of this document.
This manual is also available in Russian. Manuals can be ordered from MacDon, downloaded from the MacDon Dealer

•Wear close-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. Ensure that the driveline guards can rotate
independently of their shaft, and that they can telescope
freely.
•Use only service and repair parts made or approved by the
equipment manufacturer. Parts from other manufacturers
may not meet the correct strength, design, or safety
requirements.

•Keep hands, feet, clothing, and hair away from moving parts.
NEVER attempt to clear obstructions or objects from a
machine while the engine is running.
•Do NOT modify the machine. Unauthorized modifications
may impair the functionality and/or safety of the machine. It
may also shorten the machine’s service life.
•To avoid injury or death from the unexpected startup of the
machine, ALWAYS stop the engine and remove the key from
the ignition before leaving the operator’s seat for any reason.

•Keep the machine service area clean and dry. Wet and/or oily
floors are slippery. Wet spots can be dangerous when
working with electrical equipment. Ensure that all electrical
outlets and tools are properly grounded.
•Keep the work area well-lit.
•Keep machinery clean. Straw and chaff on a hot engine are
fire hazards. Do NOT allow oil or grease to accumulate on
service platforms, ladders, or controls. Clean machines before
they are stored.
•NEVER use gasoline, naphtha, or any volatile material for
cleaning purposes. These materials may be toxic and/or
flammable.
•When storing machinery, cover any sharp or extending
components to prevent injury from accidental contact.

•Ensure that 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 the area of bystanders, especially children, when
carrying out any maintenance, repairs, or adjustments.
•Install the transport lock or place safety stands under the
frame before working under the machine.
•If more than one person is servicing the machine at the same
time, be aware that rotating a driveline or other
mechanically-driven component by hand (for example,
accessing a lubricant fitting) will cause drive components in other areas (belts, pulleys, and knives) to move. Stay clear
of driven components at all times.

•Replace any worn, cut, abraded, flattened, or crimped hoses
and steel lines.
•Do NOT attempt any makeshift repairs to hydraulic lines,
fittings, or hoses by using tapes, clamps, cements, or welding.
The hydraulic system operates under extremely high
pressure. Makeshift repairs can fail suddenly and create
hazardous conditions.

1.6 Safety Signs
Safety signs are decals placed on the machine where there is a risk of personal injury, or where the operator should take
extra precautions before operating the controls. They are usually yellow. Operator manuals and technical manuals list the
location and explain the meaning of all safety signs placed on the machine.

replaced, ensure that the repair part displays the current
safety sign.
•Replacement safety signs are available from your MacDon
Dealer Parts Department.
1.6.1 Installing Safety Decals
If a safety decal is damaged it should be replaced.
1. Decide exactly where you are going to place the decal.
2. Clean and dry the installation area.
3. Remove the smaller portion of the split backing paper.
4. Place the decal in position and slowly peel back the remaining paper, smoothing the decal as it is applied.

To prevent serious injury, gangrene, or death:
•Do NOT go near hydraulic fluid leaks.
•Do NOT use a finger or skin to check for hydraulic
fluid leaks.
•Lower the load or relieve hydraulic pressure before
loosening any hydraulic fittings.
•High-pressure oil can easily puncture the skin, which can
