SAFETY

Page 4 AG20036
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 your owners 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 shield prior to use.
Replace any caution, warning, danger or instruction safety decal that is not readable or is missing.
Do not attempt to operate this equipment under the influence of alcohol or drugs.
Review safety instructions with all users annually.
Operator should be a responsible adult. DO NOT ALLOW PERSONS TO OPERATE OR ASSEMBLE THIS
UNIT UNTIL THEY HAVE DEVELOPED A THOROUGH UNDERSTANDING OF 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 instructions on them.
Never exceed 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.
It is the responsibility of customer to know lighting and marking requirements of local highway authori-
ties and to install and maintain equipment to provide compliance with regulations. Add extra lights when
transporting at night or during periods of limited visibility.
Lighting kits are available from your dealer or from manufacturer.
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 manufacturer.

SAFETY
FOLLOWING OPERATION

Page 8 AG20036
• Adopt safe driving practices:
- Keep 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, ensure that your speed is low enough for an
emergency stop. Keep speed to a minimum.
- Reduce speed prior to turns to avoid risk of overturning.
- Always keep 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 highway during transport. Various safety lights and devices are available
from your dealer.
• 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 tractor and equipment on road under 20 m.p.h. (40 kph) at night or during 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 load ratings. Do not cross bridges rated lower than gross weight at which you
are operating.
•SAFETY CHAINS: If equipment is going to be transported on a public highway, always
follow state and local regulations regarding safety chains and auxiliary lighting. Be sure
to check with local law enforcement agencies for your own particular regulations.
Only safety chains (not elastic or nylon/plastic tow straps) should be used to retain
connection between towing and towed machines in event of separation of primary attaching
system. Use a high strength, appropriately sized hitch pin with a mechanical retainer and
attach safety chains. Criss cross chains under tongue and secure to draw bar cage,
mounting loops, or bumper frame.
• Watch for obstructions overhead and side to side while transporting.
• Always operate equipmentin a positiontoprovidemaximumvisibility.Make allowancesforincreased
length and weight of equipment when making turns, stopping unit, etc.
