SAFETY
Rotary Cutter Manufacturer Product Council
Safety is a primary concern in the design, manufacture,
sale, and use of Rotary Cutters. As manufacturers
of Rotary Cutters, we want to conrm to you, our
customers, our concern for safety. We also want to
remind you about the simple, basic, and common sense
rules of safety when using a Rotary Cutter. Failure to
follow these rules can result in severe injury or death to
operators or bystanders.
It is essential that everyone involved in the assembly,
operation, transport, maintenance, and storage of this
equipment be aware, concerned, prudent, and properly
trained in safety. The majority of accidents involve
entanglement on the driveline or thrown objects. These
risks become greater when you do not use proper
shielding specied by the manufacturer.
Our current production machines include, as standard
equipment, guards or shields for drivelines and input
shafts, safety signs and operators manuals. If you have
an older machine which does not have current standard
safety equipment, please contact your dealer about
bringing your machine up to the current level of safety.
Below are some of the most important safety rules to
be understood and followed by anyone who works
with Rotary Cutters:
SAFETY
IMPORTANT SAFETY MESSAGE FOR OWNERS/OPERATORS OF
ROTARY CUTTERS
From members of the Farm Equipment Manufacturers Association
Before operating a Rotary Cutter, an operator must
read and understand all the information in the owner’s
manual and in the safety signs attached to the product.
A person who has not read or understood the owner’s
manual and safety signs is not qualied to operate
the cutter. Accidents occur often on machines that
are loaned or rented to someone who has not read
the owner’s manual and is not familiar with a Rotary
Cutter. If you do not have an owner’s manual or current
production safety signs, contact the manufacturer or
your dealer immediately.
Rotary cutters are designed for one-man operation.
Never operate the cutter with anyone near, or in contact
with, any part of the implement or PTO driveline. Be
sure no one else, including bystanders, is near you when
you operate this product
If operation of a Rotary Cutter around bystanders,
animals, or property that may sustain damage (such as
highway, park, or airport) is absolutely necessary, use
safety guarding recommended by the manufacturer for
thrown object prevention.
Following these simple, basic safety rules, as well
as others identied in the owner’s manual and in
product safety signs, will help minimize the possibility
of accidents and increase your productivity in using
this product. Be careful and make sure that everyone
who operates the cutter knows and understands that
it is a very powerful piece of machinery, and if used
improperly, serious injury or death may result. The nal
responsibility for safety rests with the operator of this
machine.

All power units that are not equipped with a “live”
power takeo (PTO) must be equipped with an
over-running PTO clutch. These are available
through most farm equipment stores.
The implement is operated from power supplied
from the power unit PTO. Refer to the power unit
manual for PTO engagement and disengagement
instructions.
Understand how to stop the power unit and
implement quickly in case of an emergency.
When engaging the PTO, the engine RPM should
always be at idle speed. Once engaged and ready
to start, raise PTO speed to 540-RPM and maintain
throughout operation.
TRANSPORTATION
Never transport the power unit or the implement
while under the influence of alcohol or drugs.
Always comply with all federal, state and local
laws regarding lighting, marking requirements
and transportation of farm equipment on a public
roadway.
Transport only in daylight or satisfactory artificial
light.
Be aware of overhead utility lines.
Never allow riders on the power unit or implement.
Do not operate PTO during transport.
Watch for hidden hazards on the terrain during
transport.
Do not operate or transport on steep slopes.
Do not stop, start or change directions suddenly on
slopes.
Use extreme care and reduce ground speed on
slopes and rough terrain. When encountering rough
terrain during transport, reduce the power unit
speed to minimize the horizontal movement of the
implement.
Stabilizer bars should be used during transport to
reduce lateral movement of the implement.
Ensure the towing vehicle and trailer are safely
capable of transporting the implement and that
everything is properly secured.
IMPORTANT: DO NOT operate PTO until
driveline length is correct.
NOTE: The addition of an over-running
PTO clutch may change the length of
the PTO driveline required. Be sure to
refer to the instructions on the PTO
driveline installation. Be sure that the
driveline system guarding is adequate.
11
OPERATION
Never operate the power unit or the implement
while under the influence of alcohol or drugs.
Operate only in daylight or satisfactory artificial
light.
Do not allow bystanders in the area when
operating, attaching, removing, assembling or
servicing the power unit or implement.
Never discharge directly toward people, animals or
property.
Ensure the rear-guard assembly is in place to
reduce the possibility of objects being thrown.
This implement is intended for agricultural
applications only. Do not operate within 300 feet of
bystanders or public roads or highways.
Keep hands, feet, hair and clothing away from the
power unit and implement while the power unit
engine is running. Stay clear of all moving parts.
Always sit in the power unit seat when operating
controls or starting engine. Securely fasten seat
belt, place transmission in neutral, engage brake

seat belt. Before performing any service or
maintenance, disconnect driveline from tractor
PTO.
Before working underneath the power unit or an
implement, carefully read this manual’s instructions,
disconnect driveline, raise implement, securely
block up all corners with jack stands, and check
stability. Secure blocking prevents an implement
from dropping due to hydraulic leak down,
hydraulic system failures or mechanical component
failures.
Never go underneath an implement (lowered to
the ground or raised) unless it is properly blocked
and secured. Never place any part of the body
underneath the power unit or an implement or
between moveable parts even when the engine
has been turned o. Hydraulic system leak down,
hydraulic system failures, mechanical failures,
or movement of control levers can cause an
implement to drop or rotate unexpectedly and
cause severe injury or death. Follow the power unit
and implement manual for working underneath and
blocking procedures.
Always wear relatively tight and belted clothing to
avoid getting caught in moving parts. Wear sturdy,
rough-soled work shoes and protective equipment
for eyes, hair, hands, ears, and head. When
appropriate wear a respirator or filter mask.
Keep all persons away from you while performing
adjustments, service or maintenance.
