(See page 14)Dealer’s SignaturePurchaser’s SignatureSafetyIMPORTANT SAFETY MESSAGE FOR OWNERS/OPERATORS OF ROTARY CUTTERSFrom members of the Farm Equipment Manufacturers Association’sRotary Cutter Manufacturer Product CouncilSafety is a primary concern in the design, manufacture, sale, and use ofrotary cutters. As manufacturers of rotary cutters, we want to confirm toyou, our customers, our concern for safety. We also want to remind youabout the simple, basic, and common sense rules of safety when using arotary cutter. Failure to follow these rules can result in severe injury ordeath 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 ofaccidents involve entanglement on the driveline or thrown objects.These risks become greater when you do not use proper shieldingspecified by the manufacturer.Our current production machines include, as standard equipment,guards or shields for drivelines and input shafts, safety signs andoperators manuals. If you have an older machine which does not havecurrent standard safety equipment, please contact your dealer aboutbringing your machine up to the current level of safety.Below are some of the most important safety rules to be understoodand followed by anyone who works with rotary cutters:Before operating a rotary cutter, an operator must read and understandall the information in the owner’s manual and in the safety signsattached to the product. A person who has not read or understood the2 Introductionowner’s manual and safety signs is not qualified to operate the cutter.Accidents occur often on machines that are loaned or rented to someonewho has not read the owner’s manual and is not familiar with a rotarycutter. If you do not have an owner’s manual or current productionsafety signs, contact the manufacturer or your dealer immediately.Rotary cutters are designed for one-man operation. Never operate thecutter with anyone near, or in contact with, any part of the implement orPTO driveline. Be sure no one else, including bystanders, is near youwhen you operate this productIf operation of a rotary cutter around bystanders, animals, or propertythat may sustain damage (such as highway, park, or airport) isabsolutely necessary, use safety guarding recommended by themanufacturer for thrown object prevention (such as chain guards).Following these simple, basic safety rules, as well as others identifiedin the owner’s manual and in product safety signs, will help minimizethe possibility of accidents and increase your productivity in using thisproduct. Be careful and make sure that everyone who operates the cutterknows and understands that it is a very powerful piece of machinery,and if used improperly, serious injury or death may result. The finalresponsibility for safety rests with the operator of this machine.A safety manual for Rotary Cutters is availablethrough the FEMA office.Phone: 314.878.2304E-mail: staff@FarmEquip.org

Do notoperate until driveline length is correct.Make sure driveline shield safety chain is attached asshown in this manual. Replace if damaged or broken.Check that driveline guards rotate freely on drivelinebefore putting equipment into service.Before starting power unit, check all equipment driveline guards for damage. Replace any damaged guards.Make sure all guards rotate freely on all drivelines. Ifguards do not rotate freely on drivelines, repair andreplace bearings before putting equipment into service.Inspect chain or rubber guards before each use. Replace if damaged.Remove accumulated debris from this equipment,power unit, and engine to avoid fire hazard.Power unit must be equipped with ROPS or ROPS caband seat belt. Keep seat belt securely fastened. Fallingoff power unit can result in death from being run overor crushed. Keep foldable ROPS system in “lockedup” position at all times.A minimum 20% of tractor and equipment weight mustbe on the tractor front wheels when attachments are intransport position. Without this weight, tractor couldtip over, causing personal injury or death. Theweight may be attained with a loader, front wheelweights, ballast in tires or front tractor weights.Weigh the tractor and equipment. Do not estimate.(Safety Rules continued on next page)Safety 5

SAFETY RULESATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!Stop power unit and equipment immediately uponstriking an obstruction. Turn off engine, removekey, inspect, and repair any damage beforeresuming operation.Leak down or failure of mechanical or hydraulicsystem can cause equipment to drop. MaintenanceBefore dismounting power unit or performing anyservice or maintenance, follow these steps: disengagepower to equipment, lower the 3-point hitch and allraised components to the ground, set parking brake,stop engine, remove key, and unfasten seat belt.Before performing any service or maintenance,disconnect driveline from tractor PTO.Before working underneath, carefully readOperator’s Manual instructions, disconnect driveline, raise mower, securely block up all corners withjack stands, and check stability. Secure blockingprevents equipment from dropping due to hydraulicleak down, hydraulic system failures, or mechanicalcomponent failures.Do not modify or alter or permit anyone else tomodify or alter the equipment or any of its componentsin any way.Always wear relatively tight and belted clothing toavoid getting caught in moving parts. Wear sturdy,rough-soled work shoes and protective equipmentfor eyes, hair, hands, hearing, and head; and respiratoror filter mask where appropriate.Make sure attachment is properly secured, adjusted,and in good operating condition.leak down, hydraulic system failures, mechanicalfailures, or movement of control levers can causeequipment to drop or rotate unexpectedly and causesevere injury or death.
