Introduction
This manual contains unloading, assembly, and predelivery information for MacDon M2170 and M2260 Windrowers. When
paired with one of the following MacDon auger, draper, or rotary disc headers, this windrower ably cuts and lays a variety
of grain, hay, and specialty crops in windrows:
•A40DX Auger Headers
•D1X or D1XL Draper Headers
•D2 SP Draper Headers
•R2 SP Rotary Disc Headers
•R1 SP Rotary Disc Headers
IMPORTANT:
–A R113 SP Rotary Disc Header is compatible with an M2170 or M2260 Windrower.
–A R116 SP Rotary Disc Header is compatible with an M2170 Windrower, but not an M2260 Windrower.
The windrower features Dual Direction®capability, meaning that it can be driven in cab-forward or engine-forward mode.
The designations right and left are determined by which direction the Operator is facing. The Operator is considered to be
looking cab-forward when they are facing the drive wheels, and engine-forward when facing the engine. This manual uses
the terms right cab-forward, left cab-forward, right engine-forward, and left engine-forward to refer to specific locations on
the machine.
The windrower’s ignition keys should have been bundled with the shipping documents. They are used to start the engine
and to lock the cab doors and tool box compartment.

•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.
1001207
Figure 1.9: Hydraulic Pressure Hazard
•Wear proper hand and eye protection when searching for
high-pressure hydraulic fluid leaks. Use a piece of cardboard
as a backstop instead of your hands to isolate and identify
a leak.
•If you are injured by a concentrated, high-pressure stream
of hydraulic fluid, seek medical attention immediately.
Serious infection or a toxic reaction can develop from
hydraulic fluid piercing the skin.
1000013
Figure 1.10: Safety around Equipment

1000020
Figure 1.11: Overinflated Tire
WARNING
•A tire can explode during inflation, causing serious injury
or death.
•Follow the proper procedures when mounting a tire. Failure
to do so can produce an explosion, causing serious injury
or death.
1000019
Figure 1.12: Safely Inflating Tire
WARNING
•Do NOT remove, install, or repair a tire on a rim unless you
have the proper equipment and experience to perform the
task. Take the tire and rim to a qualified tire repair shop if
necessary.
•Ensure that the tire is correctly seated on the rim before
inflating it. If the tire is not correctly positioned on the rim
or is overinflated, the tire bead can loosen on one side
causing air to escape at high speed and with great force. An
air leak of this nature can thrust the tire in any direction,
endangering anyone in the area.
•Do NOT stand over the tire when inflating it. Use a clip-on
chuck and extension hose when inflating a tire.
•Do NOT exceed the maximum inflation pressure indicated
on the tire label.
•Never use force on an inflated or partially-inflated tire.
•Ensure that all air is removed from the tire before removing the tire from the rim.

•Replace tires that have defects. Replace wheel rims that are cracked, worn, or severely rusted.
SAFETY

262175 7Revision A
1.6 Battery Safety
Working with lead-acid vehicle batteries presents several safety risks.
1000015
Figure 1.13: Safety around Batteries
WARNING
•Keep all sparks and flames away from batteries. The
electrolyte fluid in the battery cells emits an explosive gas
which can build up over time.
•Ensure that there is adequate ventilation when charging the
battery.
1000016
Figure 1.14: Safety around Batteries
WARNING
•Wear safety glasses when working near batteries.
•To avoid the loss of electrolyte fluid, do NOT tip a battery
more than 45° off of its base.
•Battery electrolyte causes severe burns. Ensure that it does
not contact your skin, eyes, or clothing.
•Electrolyte splashed into the eyes is extremely damaging. If
you are treating this condition: force the eye open and flush
it with cool, clean water for 5 minutes. Call a doctor
immediately.
•If electrolyte is spilled or splashed on one’s clothing or their
body, neutralize it immediately with a solution of baking
soda and water, then rinse the strained area with
clean water.
1000017
Figure 1.15: Safety around Batteries
WARNING
•To avoid injury from a spark or short circuit, disconnect the
battery ground cable before servicing any part of the
electrical system.
•Do NOT operate the engine with the alternator or battery
disconnected. With the battery cables disconnected and the
engine running, a high voltage can be built up if the cable
terminals touch the machine frame. Anyone touching the
machine frame under these conditions may be electrocuted.
•When working around batteries, remember that all of the
exposed metal parts are live. Never lay a metal object
across the terminals; this will generate a powerful spark and
can electrocute the holder of the tool if they are not
properly grounded.
•Keep batteries out of reach of children.

1.7 Welding Precautions
Understand these critical precautions before attempting to weld anything on the windrower.
IMPORTANT:
If the procedures below are not followed, the windrower’s electronic components may be damaged. Some components
may only be partially damaged, which would result in some electrical components failing in an intermittent way. Such faults
are very difficult to diagnose reliably.
The windrower is equipped with several sensitive electronic components. Therefore, components to be welded should be
removed from the windrower whenever possible rather than welded in place.
When welding needs to be performed on a header, disconnect the header completely from the windrower before
beginning. These same guidelines apply to plasma cutting, or any other high-current electrical operation performed on the
machine.
IMPORTANT:
Ensure that the windrower is parked on a level surface, the ignition is turned off, and the key is removed before
disconnecting anything.
The following items need to be disconnected:

1.8 Engine Safety
Operating, maintaining, and servicing an engine presents several safety risks. These risks can be reduced or eliminated by
following the relevant safety recommendations.
WARNING
Do NOT use aerosol starting aids such as ether when attempting to start the engine. Use of these substances could
result in an explosion.
CAUTION
•When starting up a new, serviced, or repaired engine, always be ready to stop the engine to prevent overspeeding.
Do this by shutting off the air and/or fuel supply to the engine.
•Do NOT bypass or disable automatic shutoff circuits. These circuits help prevent injury and damage to the engine.
For instructions, refer to the technical manual.
•Inspect the engine for potential hazards.
•Before starting the engine, ensure that no one is on, underneath, or close to the engine. Ensure that bystanders are
clear of the area.
•All protective guards and covers must be installed if the engine must be started to perform service procedures.
•Work around rotating parts carefully.
•If a warning tag is attached to the engine start switch or controls, do NOT start the engine or move the controls.
Consult whoever attached the warning tag before starting the engine.
•Start the engine from the operator’s station. Follow the procedure in the Starting Engine section of the operator’s
manual. Following the correct procedure will help prevent major damage to engine components and prevent
personal injury.
•To ensure that the jacket water heater (if equipped) and/or lubricant oil heater (if equipped) are working correctly,
check the water temperature gauge and/or oil temperature gauge during heater operation.
•Engine exhaust contains combustion products, which can be harmful to your health. Always start and operate the
engine in a well-ventilated area. If the engine is started in an enclosed area, vent the exhaust to the outside.
•Engine exhaust gases become very hot during operation and can burn people and common materials. Stay clear of
the rear of machine and avoid exhaust gases when the engine is running.
NOTE:
If the engine will be operated in very cold conditions, then an additional cold-starting aid may be required.
1.8.1 High-Pressure Rail
Fuel is delivered to the engine under high pressure. The risks of working with fuel under pressure must be understood
before the fuel system can be serviced.
WARNING
•Before disconnecting fuel lines or any other components under high pressure between the fuel pump and the high-
pressure common rail fuel system, confirm that the fuel pressure has been relieved.
•Contact with high-pressure fuel may cause fluid penetration and burn hazards. High-pressure fuel spray presents a
potential fire hazard. Failure to follow these instructions may cause injury or death.
