D60 HARVEST HEADER
1 INTRODUCTION
This instructional manual contains operating and maintenance information on the MacDon D50/D60 Harvest
Headers. They are designed to serve a dual function in your grain, hay, and specialty crop harvesting operation.
Teamed with your self-propelled windrower power unit and optional hay conditioner, the D50 and D60 Harvest
Headers will cut and lay crop into uniform fluffy windrows.
Windrowing allows starting the harvest earlier, protects the cop from wind damage, and gives you more flexibility in
scheduling combine time.
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 here, your
Header will work well for many years.
If you require more detailed service information, a Service Manual is available from your MacDon Dealer.
Use the Table of Contents and the Index to guide you to specific areas. Study the Table of Contents to familiarize
yourself with how the material is organized.
This manual must be used in conjunction with your Self-Propelled Windrower Operator's Manual.
Keep this manual handy for frequent reference and to pass on to new Operators or Owners.
A storage case for this manual is located inside the header left endshield.
Call your MacDon Dealer if you need assistance, information, or additional copies of this manual.

3.4 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. Don't take chances.
• You may need:
• Pro vide a first-aid kit for use in case of
emergencies.
• Keep a fire extinguisher on the machine.
Be sure the extinguisher is properly
maintained and be familiar with its proper
use.
• Keep young children away from
machinery at all times.
• Be aware that accidents often happen
when the Operator is tired or in a hurry to
get finished. Take the time to consider th e
safest way. Never ignore warning signs of
fatigue.
• a hard hat.
• protective shoes with slip resistant
soles.
• protective glasses or goggles.
• heavy gloves.
• wet weather gear.
• respirator or filter mask.
A
B
• hearing protection. Be aware that
prolonged exposure to loud noise
can cause impairment or loss of
hearing. Wearing a suitable hearing
protective device such as ear muffs
(A) or ear plugs (B) protects against
objectionable or loud noises.
• Wear close-fitting clothing
and cover long hair.
Never wear dangling items
such as scarves or
bracelets.
• 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.
• 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.
Form 169441 16 Revision B
SECTION 3. SAFETY
• Use only service and repair parts made or
approved by the equipment manufact urer.
Substituted parts may not meet strength,
design, or safety requirements.
• Do not modify the machine. Unauthorized
modifications may impair the function
and/or safety and affect machine life.
• Stop engine, and remove key from
ignition before leaving Operator's seat for
any reason. A child or even a pet could
engage an idling machine.
• Keep the area used for servicing
machinery 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.
• Use adequate light for the job at hand.
• Keep machinery clean. Straw and chaff on
a hot engine are 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.

NOTES:
a. Adjust reel forward to get closer to ground, or when tilting header back. Fingers/Tines will dig into ground
at extreme reel forward positions, so adjust skid shoes or header angle to compensate. Adjust reel
rearward to get reel further away from ground, or when tilting header forward.
b. Header tilt can be increased to get reel closer to ground, or decreased to get reel further away from ground
while keeping material flowing onto drapers.
c. Increase cam angle and/or speed to reduce lumps in swath and to spread crop further rearward on drapers
for a thinner crop mat.
d. Adjusting cam to more aggressive position will have a tendency to fluff up the swath and keep the heads to
the outside of the swath.
e. To leave maximum amount of stubble behind in lodged crop, raise header but increase header tilt to keep
reel close to ground. Position reel fully forward.
f. Reel may have to be moved back to prevent lumps in swath or plugging on cutterbar in thinner crops.
g. Minimum crop carrying capacity (minimum area of exposed draper betwe en reel and header backsheet)
occurs with the reel in the “furthest aft” position.
h. Maximum crop carrying capacity (maximum area of exposed draper between reel and header backsheet)
occurs with the reel in the “furthest forward” position.
i. The tip speed of the fingers/tines at the Cutterbar becomes higher than the reel speed at higher cam
settings due the nature of the cam action. Refer to the following Reel Settings Chart.

7.12 HEADER OPERATING VARIABLES
Satisfactory function of the header in all situations
requires making proper adjustments to suit
various crops and conditions.
The proper setting requires ‘balancing’ the
amount of header weight carried by the Float and
the stabilizer wheels.
CAUTION
Correct operation reduces crop loss, and allows
cutting of more acres. As well, proper
adjustments and timely maintenance will increase
the length of service you receive from the
machine.
The variables listed below and detailed on the
following pages will affect the performance of the
machine. You will quickly become adept at
adjusting the machine to give you the desired
results.

Stop engine, and remove key from ignition
before leaving Operator's seat for any reason.
A child or even a pet could engage an idling
machine.
a. Raise the header so that the stabilizer wheels are
off the ground. Shutdown engine and remove the
key.
b. Check that the Float is working properly. See
Section 7.12.2 Header Float.
c. Set up the stabilizer wheels, if installed, as
follows: Otherwise, proceed to step d.
IMPORTANT
Do not use the stabilizer wheel system
for header height control if your header
was manufactured prior to 2007. This
would result in damage to the wheel
suspension system.
CAUTION
Handle may be under tension, especially
when the wheels are on the ground. Raise
header so that wheels are off the ground
before making adjustments.
The D Series of draper headers are designed to
allow an Operator to cut the crop above the
ground for a desired stubble height, or to cut the
crop at ground level with the header on the
ground.
Cutting height will vary, depending on type of
crop, crop condition, etc. Refer to Section 7.11
HEADER SET-UP.
7.12.1.1 Cutting Off The Ground
Cutting height is controlled with a combination of
header lift cylinder adjustment and a stabilizer
wheel system or a stabilizer/slow speed transport
wheel system.
The stabilizing wheel system in both options is
designed to minimize bouncing at the header
ends and may be used to “float” the headers to
achieve an even cutting height when cutting
above ground level in cereal grains. The system
can provide very even stubble height and greatly
reduced Operator fatigue. Both systems a re only
available on 30, 35, and 40 FT. headers.

Refer to your Windrower Operator’s Manual for
details.
Form 169441 35 Revision B
SECTION 7. OPERATION
7.12.1.2 Cutting On The Ground
Cutting on the ground is controlled with a
combination of skid shoes, header angle, and
float adjustment, and not with the header lift
cylinders. Having the header "ride" on the skid
shoes allows the float linkage to float header over
obstacles and follow ground contours, rather than
supporting the header with the cylinder.
Lowering the skid shoes or decreasing header
angle increases the cutting height. This may be
desirable in stony conditions to reduce damage to
cutting components. Also, a longer stubble
length helps material dry faster.
Raising the skid shoes and increasing header
angle allows the crop to be “shaved”.
Set up the header as follows:
a. Fully raise the stabilizer wheels, or slow speed
transport wheels if installed. Refer to previous
section.
DANGER
To avoid bodily injury or death from
unexpected start-up or fall of raised machine,
stop engine, remove key and engage lift
cylinder stops before going under ma chine to
adjust skid shoes or for any reason.
b. Fully raise header, engage lift cylinder stops,
shutoff engine and remove key.
c. Adjust skid shoes to achieve desired cutting
height as follows:

7.12.3.1 Angle Adjustment
The header angle is varied by adjusting the
length of the top center-link (mechanical or
hydraulic) between the windrower and the
header.
Refer to “Header Angle in your Windrower
Operator’s Manual for adjustment details.
HEADER ANGLEGUARD ANGLE
Flatter header angles are recommended for
normal crop conditions and for stony ground
because it minimizes sickle section breakage,
and reduces soil scooping or build-up at the
cutterbar in wet conditions.
Steeper angles are recommended in “downed”
crops for better lifting action, or for cutting close
to the ground in hay for example. Refer to
Section 7.12.10 Reel Tine Pitch and Section
7.12.9 Reel Fore-Aft Position for adjustment
details.
Header angle also affects the type of windrow
that is laid. Refer to Section 7.15 WINDROW
TYPES. Choose an angle that maximizes
performance for your crop and field conditions.
Form 169441 37 Revision B
SECTION 7. OPERATION
7.12.4 REEL SPEED
Reel speed affects feeding of crop into the sickle
and onto the drapers, as well as the smoothness
and evenness of the delivered crop.
Operating the reel too fast or too slow relative to
ground speed will cause bunching.
At the proper speed, the reel discs should appear
to be being driven by the ground.
• If they look like they are skidding relative
to ground, the reel is turning too slow.
• If they look like they are spinning
excessively relative to the ground, reel
speed may be too fast.
In standing crop, reel speed should be just faster
than or equal to ground speed, sweeping crop
across the sickle.
Flattened crop or a crop that is leaning away from
the cutterbar requires a higher reel speed in
relation to ground speed. This can be achieved
by increasing reel speed, decreasing ground
speed, or both.
Excessive shattering of grain heads or crop loss
over the header back tube may be indications
that reel speed is too fast.
Excessive reel speed causes undue wear of reel
components and unnecessary load on reel drive,
resulting in uneven reel motion.
Generally, 9 bat reels can effectively operate at
lower reel speed, while minimizing crop loss in
shatter prone crops.
The reel speed is adjustable with the controls in
the windrower cab. Refer to “Reel Speed” in your
Windrower Operator’s Manual for adjustment
details.
7.12.4.1 Optional Reel Drive Sprockets - D60
Sprockets are available as an option to the
factory installed sprocket. See your MacDon
Dealer Parts Department to order sprockets.
Refer to Section 8.9.6 Reel Drive Sprocket - D60
for installation details.
Form 169441 38 Revision B
SECTION 7. OPERATION
7.12.5 GROUND SPEED
Ground speed should be such that the sickle can
cut crop smoothly and cleanly, while giving the
desired delivery of material to the opening.
Excessive ground speed results in "ragged"
cutting. Refer to Section 7.15 WINDROW TYPES
for effects of ground speed on windrow formation.
In “tough-to-cut” crops like flax, reduce ground
speed to reduce loads on cutting components
and drives.
When cutting very light crops like edible beans,
ground speed may have to be reduced to allow
reel to pull in small and short plants. Start at
3.0 - 3.5 mph (4.8 - 5.8 km/h), and adjust as
required.

Higher ground speeds require heavier float
settings to prevent excessive bouncing. This will
result in increased cutting component damage.
In most cases, as ground speed is increased,
draper and reel speed should be increased to
handle the extra material.
The chart below indicates the relationship
between ground speed and area cut for the
seven header sizes.
Example shown below: At a ground speed of 6
miles per hour (9.7 km/h) with a 25 FT. header, the
area cut in one hour would be approximately 18 acres
(7.3 hectares).

a. The draper speed is controlle d with the win drower
CDM (Cab Display Module). Refer to your SelfPropelled Windrower Operator’s Manual.
b. Adjust draper speed to achieve good feeding of
crop onto adapter draper. Excessive draper
speed will reduce draper life.
NOTE
If sufficient draper speed cannot be
achieved, a possible cause is low relief
pressure. Refer to the Technical
Service Manual for checking and
adjusting relief pressure.

SECTION 7. OPERATION
7.12.8 REEL HEIGHT
Depending on crop height, adjust reel height to
carry material through the sickle onto the drapers.
Operate windrower hydraulics as required. Refer
also to Section 7.12.9 Reel Fore-Aft Position.
REEL HEIGHT CHART
CROP CONDITION REEL POSITION
Down (Also Increase
Laying Down / Lodged

Standing
Indications that reel may be too low are:
• crop loss over the header back tube;
• disturbance of crop on the drapers by the
reel fingers; or
• the crop being pushed down by the tine
tubes.
IMPORTANT
Maintain adequate clearance to
prevent fingers contacting sickle or the
ground. Refer to Section 8.9.1 Reel
Clearance to Cutterbar.
Reel Speed and/or
Cam Setting)
Up
NOTE
The back edge of the reel cam disc is the gauge
indicator.
• For straight standing crop, center the reel
over the cutterbar (4 - 5 on gauge).
• For crops that are down, tangled, or leaning,
it may be required to move reel ahead of
cutterbar (to a lower number on the gauge).
IMPORTANT
When difficulty is encountered picking
up down crop, start by adjusting
header angle to a steeper position.
This tilts the entire reel/sickle/draper
combination, and is often all that is
required.
Refer to “Header Angle” in your
Windrower Operator’s Manual for
adjustment details. Adjust reel position
only if header angle adjustments are
not satisfactory.
NOTE
In difficult to pick up crops such as rice
or severely lodged crops that require
full forward positioning of the reel, the
reel tine pitch can be set to provide
proper placement of the crop onto the
drapers.
7.12.9 REEL FORE-AFT POSITION
Reel position has been found to be a critical
factor in achieving good results in adverse
conditions. The reel position is factory set for
average straight standing crop, and can be
adjusted forward and backward for different crop
conditions.
A gauge decal is provided on the reel right
support arm for identifying a preferred position.
Refer to Section 7.12.10 Reel Tine
Pitch for adjustment details.
IMPORTANT
Operating with the reel too far forward
can cause the fingers to contact the
ground before the cutterbar.
Lower the skid shoes or adjust header
tilt as required when operating with the
reel in this position. Otherwise,
damage to the fingers will occur.

SECTION 7. OPERATION
7.12.10 REEL TINE PITCH
IMPORTANT
The following describes the concept
and operational guidelines of the
pick-up reel. Please read carefully
before operating the machine.
7.12.10.1 Concept
The pick-up reel is designed to pick up flattened
and severely lodged crops. It is not always
necessary to increase the tine pitch (higher cam
setting) to pick up crops that are lodged, but
rather the cam settings are mainly used to
determine how the crop will get delivered to the
drapers.
The position of the fingers relative to ground (tine
pitch) is not significantly affected by the cam
setting. For example, the cam position range is
33 degrees, but the corresponding finger pitch
range is only 5 degrees at the lowest point of reel
rotation.
For best performance, use the minimum cam
setting that will deliver the crop past the rear edge
of the cutterbar and onto the drapers.
7.12.10.2 Operating Guidelines
• Cam Positions 3 and 4 - Mainly used to
leave long stubble. Allows the reel to reach
forward and lift the crop across the knife and onto
the drapers. The further forward the reel, the
higher the cam angle should be.
Cam 4 would be used with the reel being fully
forward to leave the maximum amount of stubble
in lodged crops. This setting gives a finger tip
speed approximately 30% faster than the reel
speed.
Cam Position 4, Header Angle At Maximum,
and Reel Fully Forward - Provides the maximum
amount of reel reach below the cutterbar to pick
up lodged crops, and gives a finger tip speed
approximately 35% faster than the reel speed.
Cutting height is set to approximately 8 inches
(203 mm) to leave a significant amount of
stubble. In some crops, it is possible to double
ground speed because the amount of material
that is being cut is less.
NOTE
High cam settings with the reel fore-aft
position at 4 - 5, severely decrease the
draper capacity because the reel
disrupts crop flow across the drapers.
The fingers are still engaged in the crop
that is moving on the drapers.
The following outlines the function of each cam
setting and includes guidelines for set-up in
various crop conditions. The setting numbers are
visible above the slots on the cam disc. Refer to
Section 7.12.10.3 Cam Adjustment.
• Cam Position 1 - Delivers the most even
crop flow onto the drapers with out fluffing up or
disturbing the material. The crop is released
quite close to the cutterbar, and works best with
the cutterbar on the ground. Some crops will not
be delivered past the cutterbar when the cutterbar
is raised off the ground, and the reel is pushed
forward. Initially, have the reel speed “about
equal” to the ground speed.
• Cam Position 2 - Recommended starting
position for most crops and conditions. This
setting gives a finger tip speed approximately
20% faster than the reel speed.
If crops tend to stall on the cutterbar with the reel
in a “forward” position, the cam angle should be
increased to push the crop past the rear edge of
the cutterbar.
If the crop is getting fluffed or the flow across the
drapers is disrupted, the cam angle can be
decreased.
High cam settings are recommended
only with the reel at or close to “full
forward” settings.
IMPORTANT
The reel to cutterbar clearance should
always be checked following
adjustments to reel tine pitch and reel
position.
Refer to Section 8.9.1 Reel Clearance
to Cutterbar and, 8.9.2 Reel Frown
Adjustment.
For detailed reel set-up information, refer to
Section 7.11 HEADER SET-UP.

SECTION 7. OPERATION
7.13 DELIVERY OPENING/DECK SHIFT
The width and position of the delivery opening
affects the width and configuration of the
windrow.
The decision to widen or narrow the center
delivery opening; or whether or not to double
windrow should be based on the following factors:
• combine pick-up capability,
• type and yield of crop,
• weather conditions (rain, humidity, wind),
and,
• drying time available.
Refer to Section 7.15 WINDROW TYPES for the
strengths and weaknesses of the vario us windrow
configurations with respect to these factors.
The 25 FT. to 40 FT. D60 Harvest Headers can
lay double windrows by shifting the decks for
delivery to either the right or left side of the
header. Refer to Section 7.14 DOUBLE
WINDROWING.
The D60 Harvest Headers with manual deck shift
can also provide a range of windrow widths.
Refer to Section 7.13.1 Delivery Opening - D60.
7.13.1 DELIVERY OPENING - D60
Both decks can be positioned to vary the delivery
opening from 60.61 to 69.7 in. (1540 to 1770 mm)
for the 15 FT. header, and from 67.1 to 76.7 in.
(1720 to 1950 mm) for 20 - 40 FT. models.
Adjust as follows:

of a windrow is measured:
• Weight Distribution - heads and stalks
distributed evenly across full width of
windrow.
WINDROW TYPE DESCRIPTION
The most desirable form of windrow,
stalks are crossed and interwoven.
Heads are distributed across full width
of windrow. This windrow can be formed
by center delivery only.
HERRINGBONE
FANTAIL
The stalk tips are crossed in the center,
and heads are in line along outside
edges. This windrow can be formed by
center delivery only.

SECTION 7. OPERATION
7.16 HAYING TIPS
The following information may be useful when
using the D50 and D60 Harvest Headers in hay
crops:
d. If there is no wind, saturated air becomes trapped
around the windrow. Raking or tedding will
expose the hay to fresher, less saturated air.
e. Cutting hay perpendicular to the direction of the
prevailing winds is also recommended.
7.16.1 CURING
a. A quick cure will maintain top quality because:
• 5% of the protein is lost for each day hay lies
on the ground,
• The sooner the cut hay is off, the earlier the
start for next growth.
b. Leaving the windrow as wide and thin as possible
makes for the quickest curing
c. The cured hay should be baled as soon as
possible.
7.16.2 TOPSOIL MOISTURE
a. On wet soil, the general rule of "wide and thin"
does not apply. A narrower windrow will dry faster
than hay left flat on wet ground.
b. When the ground is wetter than the hay, moisture
from the soil is absorbed by the hay above it.
Determine topsoil moisture level before cutting.
Use a moisture tester or estimate level:
LEVEL % MOISTURE CONDITION
Wet Over 45% Soil is Muddy
Damp 25 - 45% Shows Footprints
Dry Under 25% Surface is Dusty
c. If ground is wet due to irrigation, wait until soil
moisture drops below 45%.
d. If ground is wet due to frequent rains, cut when
weather allows, and let the forage lie on wet
ground until it dries to the moisture level of the
ground.
e. The cut hay will dry no more until the ground
under it dries, so consider moving the windrow to
drier ground.
7.16.4 WINDROW CONFIGURATION
It is recommended that a windrow with the
following characteristics be produced. Refer to
Section 7.12 HEADER OPERATING VARIABLES
for instructions on adjusting the header.
CONFIGURATION ADVANTAGE
High And Fluffy
Consistent Formation,
Not Bunchy
Even Distribution of
Material Across
Windrow
Properly Conditioned Prevents excessive leaf damage.
The movement of air through the
windrow is more important to the
curing process than direct sunlight.
Permits an even flow of material
into the baler, chopper etc. and
allows for more even drying.
Results in even and consistent
bales to minimize handling and
stacking problems.
7.16.5 DRIVING ON WINDROW
Driving on previously cut windrows can lengthen
drying time by a full day in hay that will not be
raked.
If practical, set forming shields for a narrower
windrow that can be straddled.
NOTE
Driving on the windrow in high yielding
crops may be unavoidable if a full width
windrow is necessary.
7.16.6 RAKING AND TEDDING
Raking or tedding speeds up drying, however the
benefits must be weighed against the additional
leaf losses which will result.
7.16.3 WEATHER AND TOPOGRAPHY
There is little or no advantage to raking or tedding
if the ground beneath the windrow is dry.
a. Cut as much hay as possible by midday, when
drying conditions are best.
b. Fields sloping south get up to 100% more
exposure to the sun's heat than do north sl oping
fields.
If hay is baled and chopped, consider baling the
south facing fields, and chopping fields facing
Large windrows on damp or wet ground should
be turned over when they reach 40 - 50%
moisture.
Hay should not be raked or tedded at less than
25% moisture, or excessive yield losses will
result.
north.
c. When relative humidity is high, the evaporation
rate is low, and hay dries slower.
Form 169441 58 Revision B
SECTION 7. OPERATION
7.16.7 CHEMICAL DRYING AGENTS
Hay drying agents work by removing wax from
legume surfaces, enabling water to escape and
evaporate faster.
However, treated hay lying on wet ground will
also absorb ground moisture faster.
Before deciding to use a drying agent, costs and
benefits relative to your area should be carefully
compared.
Form 169441 59 Revision B
SECTION 7. OPERATION
7.17 DRAPER DEFLECTORS
D60 single knife headers are equipped with
rubber deflectors that are attached to the inboard
side of the endsheets to prevent material from
falling through the gap between the endsheet and
the draper.
In some cases material hesitates on the
deflectors, and will not flow onto the draper.
Replace the existing deflector with a narrower
one, or rework the existing deflector.

7.21 TRANSPORTING HEADER
WARNING
Do not drive windrower with header attached
on a road or highway at night, or in conditions
which reduce visibility, such as fog or rain.
The width of the header may not be apparent
under these conditions.
7.21.1 ON THE WINDROWER
CAUTION
• Check local laws for width regulations
and lighting or marking requirements
before transporting on roads.
• Follow all recommended procedures in
your Windrower Operator's Manual for
transporting, towing etc.
• Disengage header drive clutch when
travelling to and from the field.
• Before driving windrower on a roadway,
be sure flashing amber lamps, red tail
lamps and head lamps are clean and
working properly. Pivot amber lamps for
best visibility by approaching traffic.
Always use these lamps on roads to
provide adequate warning to other
vehicles.
• Do not use field lamps on roads, they may
confuse other drivers.
• Before driving on a roadway, clean slow
moving vehicle emblem and reflectors.
Adjust rear view mirror and clean
windows.
• Lower the reel fully and raise header
unless transporting in hills. Maintain
adequate visibility and be alert for
roadside obstructions, oncoming traffic
and bridges.
• When travelling down hill, reduce speed
and keep header at a minimum height.
This provides maximum stability if
forward motion is stopped for any reason.
Raise header completely at bottom of
grade to avoid contacting ground.
• Travel speed should be such that
complete control and machine stability
are maintained at all times.
7.21.2 TOWING
Headers with the Slow Speed Transport/Stabilizer
Wheel option can be towed behind a properly
configured MacDon windrower or an agricultural
tractor. Refer to the Windrower Operator’s
Manual.
7.21.2.1 Attaching Header To Towing Vehicle
CAUTION
To avoid bodily injury and /or machine damage
caused by loss of control:
• Do not tow w ith a vehicle weighing less
than the header to ensure adequate
braking performance and control.
• Do not use a pick-up truck to tow header.
Use only an agricultural tractor, combine,
or properly configured MacDon
windrower.
• Ensure that reel is down and fully back on
support arms to increase header stability
in transport. For headers with hydraulic
reel fore-aft, never connect the fore-aft
couplers to each other. This would
complete the circuit and allow the reel to
creep forward in transport, resulting in
instability.
• Check that all pins are properly secured in
transport position at wheel supports,
hitch and cutterbar support.
• Check tire condition and pressure p rior to
transporting.
• Connect hitch to towing vehicle with a
proper hitch pin with a spring locking pin
or other suitable fastener.
• Attach hitch chain to towing vehicle.
Adjust chain length to remove all slack
except what is needed for turns.
• Connect header wiring harness 7-pole
plug to mating receptacle on towing
vehicle. (The 7-pole receptacle is av ailable
from your MacDon Dealer parts
department).
• Ensure lights are functioning properly,
and clean the slow moving vehicle
emblem and other reflectors. Use
flashing warning lights unless prohibited
by law.

WARNING
• Avoid high-pressure fluids. Escaping fluid
can penetrate the skin causing serious
injury. Relieve pressure before
disconnecting hydraulic lines. Tighten all
connections before applying pressure.
Keep hands and body away from pinholes and nozzles which eject fluids
under high pressure.
• If ANY fluid is injected
into the skin, it must
be surgically remov ed
within a few hours
by a Doctor familiar
with this type of
injury or gangrene
may result.
• Use a piece of
cardboard or paper
to search for leaks.
IMPORTANT
Keep hydraulic coupler tips and
connectors clean. Dust, dirt, water and
foreign material are the major causes
of hydraulic system damage.
DO NOT attempt to service hydraulic
