SAFETY...YOU CAN LIVE WITH IT
EQUIPMENT SAFETY GUIDELINES
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 in this section. To avoid personal injury, study the following precautions and insist those working
with you, or you yourself, follow them.
In order to provide a better view, certain illustrations in this manual may show an assembly with a safety shield
removed. However, equipment should never be operated in this condition. Keep all shields in place. If shield
removal becomes necessary for repairs, replace the shield prior to use.
Replace any caution, warning, danger or instruction safety decal that is not readable or is missing. Location
of such decals is indicated in this booklet.
Do not attempt to operate this equipment under the influence of alcohol or drugs.
Review the safety instructions with all users annually.
Operator should be a responsible adult. DO NOT ALLOW PERSONS TO OPERATE OR ASSEMBLE THIS
UNIT UNTILTHEY HAVE DEVELOPED A THOROUGH UNDERSTANDING OF THE SAFETY PRECAUTIONS
AND HOW IT WORKS.
To prevent injury or death, 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 a piece of machinery. If its ability to do a job, or to do so safely is in question-DON’T
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.
Lighting kits are available from your dealer or from the manufacturer.

• Install the safety chain by crossing the chains under the tongue and secure to the draw bar cage, 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.
• Keep hands and clothing clear of moving parts.
• Do not clean, lubricate, or adjust your equipment while it is moving.
• When halting operation, even periodically, set the tractor or towing vehicle brakes, disengage the PTO, shut off the
engine, and remove the ignition key.
• Be especially observant of the operating area and terrain- watch for holes, rocks, or other hidden hazards. Always
inspect the area prior to operation.
- DO NOT operate near the edge of drop-offs or banks.
- DO NOT operate on steep slopes as overturn may result.
- Operate up and down (not across) intermediate slopes. Avoid sudden starts and stops.
• Pick the levelest possible route when transporting across fields. Avoid the edges of ditches, gullies, and steep
hillsides.
• Be extra careful when working on inclines.
• 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.
• Avoid loose fill, rocks, and holes; they can be dangerous for equipment operation or movement.
• Allow for unit length when making turns.
• Do not walk or work under raised components or attachments unless securely positioned and blocked.
• Keep all bystanders, pets, and livestock clear of the work area.
• Operate the towing vehicle from the operators seat only.
• Never stand alongside of unit with engine running or attempt to start engine and/or operate machine while standing
alongside of unit.
• Never leave running equipment attachments unattended.
• As a precaution, always recheck the hardware on equipment following every 100 hours of operation. Correct all
problems. Follow the maintenance safety procedures.
•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 safety chain and auxiliary lighting 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.
DURING OPERATION
!

Page 9
FOLLOWING OPERATION
• Following operation, or when unhitching, stop the tractor or towing vehicle, set the brakes, disengage the PTO and
all power drives, shut off the engine and remove the ignition keys.
• Store the unit in an area away from human activity.
• 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.
• Make sure all parked machines are on a hard, level surface and engage all safety devices.
• Wheel chocks may be needed to prevent unit from rolling.
HIGHWAY AND TRANSPORT OPERATIONS
• Adopt safe driving practices:
- Keep the brake pedals latched together at all times. NEVER USE INDEPENDENT BRAKING WITH MACHINE
IN TOW, LOSS OF CONTROL AND/OR UPSET OF UNIT CAN 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.
- 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 under 20 mph (40 kph) at night or during the day, use flashing
amber warning lights and a slow moving vehicle (SMV) identification emblem.
• Plan your route to avoid heavy traffic.
• Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including narrow bridges,
intersections, etc.
• 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
the unit, etc.
• Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.
• Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a
closed building. The exhaust fumes may cause asphyxiation.
• Before working on this machine, stop the towing vehicle, set the brakes, disengage the PTO
and all power drives, shut off the engine and remove the ignition keys.

• Always use the proper tools or equipment for the job at hand.
• Use extreme caution when making adjustments.
• Follow the torque chart in this manual when tightening bolts and nuts.
• Never use your hands to locate a hydraulic leak on attachments. Use a small piece of cardboard
or wood. Hydraulic fluid escaping under pressure can penetrate the skin.
• When disconnecting hydraulic lines, shut off hydraulic supply and relieve all hydraulic
pressure.
• Openings in the skin and minor cuts are susceptible to infection from hydraulic fluid.
Without immediate medical treatment, serious infection and reactions can occur.
• Replace all shields and guards after servicing and before moving.
• After servicing, be sure all tools, parts and service equipment are removed.
