MacDon HC10 Hay Conditioner
Published June, 2016

Introduction
This manual contains safety information, setup instructions, operating and maintenance procedures, and parts
information for the MacDon HC10 Hay Conditioner.
Conditioning or crimping cut hay allows moisture release for quicker drying and earlier processing. This hay
conditioner, when teamed with an M-Series Self-Propelled Windrower and a double-knife drive D-Series Draper
Header, will condition crop cut by the header, which the windrower lays into uniform, fluffy windrows.
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.
The HC10 Hay Conditioner is NOT intended for use with the M205 Self-Propelled Windrower. Refer to the
following table to determine if the HC10 Hay Conditioner is compatible with your windrower in your market:
Carrier (North America only) MacDon M150, M155, M155E4, and M200 Self-Propelled Windrowers
Carrier (Export only) MacDon M100, M105, M150, M155, and M200 Self-Propelled Windrowers
CAREFULLY READ ALL THE MATERIAL PROVIDED BEFORE ATTEMPTING TO UNLOAD, ASSEMBLE, OR USE
THE MACHINE.
Use this manual as your first source of information about the machine. If you follow the instructions given in this
manual, your hay conditioner will work well for many years. Use this manual in conjunction with your windrower and
draper header manuals.
Use the Table of Contents and Index to guide you to specific topics. Review the Table of Contents to familiarize
yourself with how the material is organized.
Keep this manual handy for frequent reference and to pass on to new Operators or Owners. Call your Dealer if you
need assistance, information, or additional copies of this manual.

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 the protective clothing and personal safety
devices that could be necessary for the 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 the
fire extinguisher is properly maintained. Be familiar with
its proper use.
• Keep young children away from the machinery at
all times.
• Be aware that accidents often happen when the
Operator is tired or in a hurry. Take the time to
consider the safest way. Never ignore the warning
signs of fatigue.
Figure 1.4: Safety Equipment
214033 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 the shaft and can telescope freely.
• Use only service and repair parts made or approved by
the 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 the engine is running.
•DoNOT modify the machine. Non-authorized
modifications may impair machine function and/or
safety. It may also shorten the machine’s life.
• To avoid bodily injury or death from unexpected startup
of machine, ALWAYS stop the engine and remove
the key from ignition before leaving operator’s seat for
any reason.
Figure 1.6: Safety around Equipment
• Keep the service area clean and dry. Wet or oily floors
are slippery. Wet spotscan 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
214033 4Revision A

SAFETY
1.4 Maintenance Safety
To ensure your safety while maintaining the machine:
• Review the operator’s manual and all safety items
before operation and/or maintenance of the machine.
• Place all controls in Neutral, stop the engine, set
the park brake, remove the 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 the job at hand Figure 1.8: Safety around Equipment
• Relieve pressure from hydraulic circuits before servicing
and/or disconnecting the 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 the area of bystanders, especially children, when
carrying out any maintenance, repairs or, adjustments.
• Install 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 lube fitting) will cause drive components in
other areas (belts, pulleys, and knives) to move. Stay
clear of driven components at all times.

•Wearprotectivege
ar when working on the machine.
• Wear heavy gloves when working on knife components.

SAFETY
1.5 Hydraulic Safety
• Always place all hydraulic controls in Neutral
before dismounting.
• Make sure that all components in the 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 the 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.

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 the repair part also bears the current
safety sign.
• Safety signs are available from your Dealer
Parts Department.
Figure 1.14: Operator’s Manual Decal
1.6.1 Installing Safety Decals
1. Clean and dry installation area.
2. Decide on exact location before you remove decal backing paper.
3. Remove smaller portion of split backing paper.
4. Place sign in position and slowly peel back remaining paper, smoothing sign as it is applied.
5. Prick small air pockets with a pin and smooth out.
