SAFETY FIRST!

Equipment Safety Guidelines

Safety of the operator is one of the main concerns in designing and developing a new piece of
equipment. Designers and manufacturers build in as many safety features as possible. However,
every year many accidents occur which could have been avoided by a few seconds of thought and
a more careful approach to handling equipment. You, the operator, can avoid many accidents by
observing the following precautions. To avoid personal injury, study the following precautions
and insist that those working with you, or for you, follow them.

Replace any CAUTION, WARNING, DANGER, or instruction safety decal that is not readable or
missing.

Do not attempt to operate this equipment under the influence of drugs or alcohol.

Review the safety instructions with all users annually.

This equipment is dangerous to children and persons unfamiliar with its operation. The operator
should be a responsible adult familiar with farm machinery and trained in this equipment’s
operations. Do not allow persons to operate or assemble this unit until they have read this

manual and have developed a thorough understanding of the safety precautions and of how
it works.

To prevent injury, use a tractor equipped with a Roll Over Protective System (ROPS). Do not
paint over, remove, or deface any safety signs or warning decals on your equipment. Observe all
safety signs and practice the instructions on them.

Never exceed the limits of the transport cart or the harrows. If their ability to do a job, or to do so
safely, is in question - DO NOT TRY IT.

Lighting and Marking

It is the responsibility of the customer to know the lighting and marking requirements of the local
highway authorities and to install and maintain the equipment to provide compliance with the
regulations. Add extra lights when transporting at night or during periods of limited visibility.

Safety Sign Care

 Keep safety signs clean and legible at all times.

 Replace safety signs that are missing or have become illegible.

 Replacement parts that display a safety sign should display the same sign.

 Safety signs are available from your Distributor, Dealer Parts Department, or the factory.

How to Install Safety Signs:

6

 Be sure that the installation area is clean and dry.

 Decide on the exact position before you remove the backing paper.

Tire Safety

 Failure to follow proper procedures when mounting a tire on a wheel or rim can produce an

explosion which may result in serious injury or death.

 Do not attempt to mount tires unless you have the proper equipment and experience to do the

job.

 Inflating or servicing tires can be dangerous. Whenever possible, trained personnel should be

called to service and/or mount tires.

 Always order and install tires and wheels with appropriate capacity to meet or exceed the

weight of the unit. Be sure to inflate tires to tire manufacturer’s specifications

 Tires that are provided by the manufacturer are designed for speeds LESS THAN 20mph. Do

Not exceed or tire failure will occur.

Remember:

Your best assurance against accidents is a careful and responsible operator. If there is any
portion of this manual or function you do not understand, contact your local authorized
dealer or the manufacturer.

Before Operation:

 Carefully study and understand this manual.

 Do not wear loose fitting clothing which may catch in moving parts.

 Always wear protective clothing and substantial shoes.

 It is recommended that suitable protective hearing and (eye protection) sight protectors be

worn.

 Keep wheel lug nuts or bolts tightened.

 Assure that the tires are inflated evenly.

 Give the unit a visual inspection for any loose bolts, worn parts, or cracked welds, and make

necessary repairs. Follow the maintenance safety instructions included in this manual.

 Before using the hydraulics on the cart, be sure all fittings and connections are tight.

 Be sure that there are no tools lying on the unit.

 Make sure that the area is clear of children, animals, and other obstacles before using.

 Don’t hurry the learning process or take the unit for granted. Ease into it and become familiar

with your new equipment. Practice operation of your new unit. Completely familiarize
yourself and other operators with its operation before using.

7

 Securely attach to towing unit. Use a high strength, appropriately sized hitch pin with a

mechanical retainer and attach safety chain.

 Do not allow anyone to stand between the tongue or hitch and the towing vehicle when

backing up to the equipment.

During Operation:

 SAFETY CHAIN - If equipment is going to be transported on a public highway, a safety chain

should be obtained and installed. Always follow state and local regulations regarding a safety
chain when towing farm equipment on a public highway. Be sure to check with local law
enforcement agencies for your own particular regulations. Only a safety chain (not an elastic
or nylon/plastic tow strap) should be used to retain the connection between the towing and
towed machines in the event of separation of the primary attaching system.

 Install the safety chain by crossing the chains under the tongue and secure to the draw bar cage

or hitch or bumper frame.

 Beware of bystanders, particularly children! Always look around to make sure that it is safe

to start the engine of the towing vehicle or move the unit. This is particularly important with
higher noise levels and quiet cabs, as you may not hear people shouting.

 NO PASSENGERS ALLOWED - Do not carry passengers anywhere on, or in, the tractor or

equipment, except as required for operation.

 Keep hands and clothing clear of moving parts.

 Do not clean, lubricate, or adjust your equipment while it is moving.

 When altering operation, even periodically, set the tractor or towing vehicle brakes, shut off

the engine, and remove the ignition key.

 Do not operate the hydraulic cylinders without the flow restrictors installed; the free falling

harrow sections may cause serious injury.

 Pick the smoothest and flattest possible route when transporting across fields. Avoid the edges

of ditches or gullies and steep hillsides.

 Periodically clear the equipment of brush, twigs, or other materials to prevent buildup of dry

combustible materials.

 Maneuver the tractor or towing vehicle at safe speeds.

 Avoid overhead wires or other obstacles. Contact with overhead lines could cause serious

injury or death.

 Allow for unit length when making turns.

 Do not walk or work under raised wings unless securely positioned in wing rests.

 Keep all bystanders, pets, and livestock clear of the work area, particularly when raising or

lowering harrow sections.

 Operate the towing vehicle from the operator’s seat only.

 As a precaution, always recheck the hardware on equipment periodically. Correct all

problems. Follow the maintenance safety procedures.

8

Following Operation:

 When disconnecting, stop the tractor or towing vehicle, set the brakes, secure the wings in the

wing rests, relieve hydraulic fluid pressure, shut off the engine and remove the ignition keys.
Make sure all jack and support stands are in place before removing hitch pins.

 Store the unit in an area away from human activity on a hard level surface.

 Do not park equipment where it will be exposed to livestock for long periods of time. Damage

and livestock injury could result.

 Do not permit children to play on or around the stored unit.

Highway and Transport Operations:

 Make sure all transport lock provisions are in place and jack/parking stands are in their storage

position before transporting the unit.

 Adopt safe driving practices:

– Keep the brake pedals latched together at all times. NEVER USE INDEPENDENT

BRAKING WITH MACHINE IN TOW AS LOSS OF CONTROL AND/OR UPSET
OF UNIT MAY RESULT.

– Always drive at a safe speed relative to local conditions and ensure that your speed is low

enough for an emergency stop to be safe and secure. Keep speed to a minimum.

– Reduce speed prior to turns to avoid the risk of overturning.

– Avoid sudden uphill turns on steep slopes.

– Always keep the tractor or towing vehicle in gear to provide engine braking when going

downhill. Do not coast.

– Do not drink and drive!

 Comply with state and local laws governing highway safety and movement of farm machinery

on public roads.

 Use approved accessory lighting flags and necessary warning devices to protect operators of

other vehicles on the highway during daylight and nighttime transport. Various safety lights
and devices are available from your dealer.

 The use of flashing amber lights is acceptable in most localities. However, some localities

prohibit their use. Local laws should be checked for all highway lighting and marking
requirements.

 When driving the tractor and equipment on the road or highway under 20 mph at night or

driving during the day, use flashing amber warning lights and a slow moving vehicle (SMV)
identification emblem.

 Remember, tires supplied by the manufacturer are designed to operate LESS THAN 20mph.

Do Not exceed or tire failure will occur.

 Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including

narrow bridges, intersections, etc. Plan your route to avoid heavy traffic.

9

 Be observant of bridge loading ratings. Do not cross bridges rated lower than the gross weight

at which you are operating.

 Watch for obstructions overhead and to the side while transporting.

 Always operate equipment in a position to provide maximum visibility at all times. Make

allowances for increased length and weight of the equipment when making turns, stopping,
etc.

Performing Maintenance:

 Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.

 Before working on this machine, stop the tractor or towing vehicle, set the brakes, lower into

field position, relieve the hydraulic fluid pressure, shut off the engine and remove the ignition
keys.

 Always use safety support and block the wheels. When performing maintenance, never use a

jack to support the machine. Assist the jack with blocks or other adequate support.

 Use extreme caution when making adjustments.

 When disconnecting hydraulic lines, shut off hydraulic supply and relieve all pressure.

 Never use hands to locate a hydraulic leak on attachments. Use a piece of cardboard or wood.

Hydraulic fluid escaping under pressure can penetrate the skin.

 Openings in the skin and minor cuts are susceptible to infection from hydraulic fluid. If

injured by escaping hydraulic fluid, see a doctor at once. Gangrene can result. Without
immediate medical treatment, serious infection and reactions can occur.

 When installing, replacing, or repairing hydraulic system cylinders or parts, make sure that the

entire system is charged and free of air before resuming operations. Failure to bleed the
system of all air can result in improper machine operation, causing severe injury.

 After servicing, be sure all tools, parts, and service equipment are removed.

 Never replace hex bolts with less than grade five bolts unless otherwise specified.

 Where replacement parts are necessary for periodic maintenance and servicing, genuine

factory replacement parts must be used to restore your equipment to original specifications.
The manufacturer will not claim responsibility for damages as a result of the use of
unapproved parts and/or accessories.

 If equipment has been altered in any way from original design, the manufacturer does not

accept any liability for injury or warranty.

10

MAINTENANCE AND SERVICE SCHEDULE

 Prior to each use, check for loose bolts and replace lost or worn parts.

 Grease hinge pins before each use when necessary.

Note: Clean grease fittings and replace those that are broken or missing.

 Inspect and repack wheel bearings at the beginning of each year.

 Remove dirt and debris from the harrow sections before storage.

 Parts diagrams and listings for service and repair references may be found in appendix B.

OPERATING SUGGESTIONS

There are some important points to remember in order to obtain the best possible results from your
McFarlane harrow.

 To maximize the harrow’s performance, it should be towed at speeds ranging from six to nine

(6 - 9) mph. This keeps the field debris moving through the harrow sections and avoids
clogging. The best results will be obtained after the paint has been scoured from the teeth.

 Choose the angle of attack of the harrow teeth based on field conditions. For more

information see the section titled Angle of Attack.

 Getting the unit ready for transport includes the following steps:

1. Rotate the harrow sections up.

2. Swing the wings forward and lock them into the wing rests.

 Getting the unit ready for field use includes the following steps:

1. Unlock the wings from the wing rests and swing the wings out.

2. Rotate the harrow sections down.

 Field Operation - while turning on the headlands (field ends) slow down and rotate the toolbar

up so the harrow sections begin to lift off the ground. Once traveling straight forward again,
lower the sections to the ground.

11

ASSEMBLY SUGGESTIONS
