CHECKLISTS

DELIVERY CHECKLIST

Inspect the cutter thoroughly after assembly to be certain it is set up properly. The following checklist is a reminder of points to inspect. Check off each item as it is found satisfactory or after proper adjustment is made.

h Check operator's manual and familiarize the opera-

tor with all sections of it.

h Check that all safety shielding is in place. h Check all bolts to be sure they are tight or adjusted

properly at hinged locations.

h Check that all cotter pins are properly installed. h Check PTO driveline. Make sure it is the correct

length to operate cutter with intended tractor.

h Check that all lubrication points with grease fittings

have been lubricated.

h Check that blades have been properly installed.

Check all blade beam bolts.

h Check cutter attitude, after mounting on tractor. h Check that gearbox is properly serviced and seals

are not leaking.

DAILY CHECKLIST

h Check that cutter is properly and securely attached

to tractor.

h During inspection, check that all nuts and bolts are

secure and that all safety shields are in place.

h It is very important that the blade carrier nut and

blade bolts are checked and tightened frequently.

h Check condition of blades and security of attach-

ment.

h Check that PTO driveline shields are securely

locked and clears the front of the cutter frame.

h Adjust the tractor top link so the front of the cutter is

slightly above the rear. Then raise the tractor lift very slowly, making sure that the front drive shaft shield does not hit the front of the cutter. If it does, damage will be done to the drive shaft shield and, if it hits hard enough, it will also damage the drive shaft itself. (See page 20.)

NOTE: This type of damage is not covered under warranty , as it is totally under the control and the responsibility of the operator.

h Check shear bolt for proper grade and installation. h Check front of input gearbox shaft and make sure

that snap ring is properly installed.

h All safety signs (decals) in place and readable. h When the cutter is transported on a road or highway

at night or during the day, safety devices should be used for adequate warning to operators of other vehicles.

IMPORTANT!

Gearbox was not filled at factory. It must be serviced before operating. Fill to proper level with SAE 90 oil. Failure to service will result in damage to gearbox.

SAFETY INSTRUCTIONS (continued)

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 in this section. To avoid personal injury, study the following precautions and insist those working with you, or for you, follow them.

In order to provide a better view, certain photographs or 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.

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 signs on your equipment. Observe all safety signs and practice the instruction 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.

Do not modify the equipment in any way. Unauthorized modification may impair the function and/or safety and could affect the life of the equipment.

In addition to the design and configuration of this implement, including Safety Signs and Safety Equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer also to Safety Messages and Operation Instructions in each of the appropriate sections of the Tractor and Cutter Manuals. Pay close attention to the Safety Signs affixed to the Tractor and the Cutter.

Replace any CAUTION, WARNING, DANGER or instruction safety sign that is not readable or is missing. Location of such safety signs is indicated in this booklet.

Never use alcoholic beverages or drugs which can hinder alertness or coordination while operating this equipment. Consult your doctor about operating this machine while taking prescription medications.

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

SAFETY TRAINING

Safety is a primary concern in the design and manufacture of our products. Unfortunately , our efforts to provide safe equipment can be wiped out by a single careless act of an operator.

In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

It has been said, “The best safety device is an informed, careful operator.” We ask you to be that kind of an operator. It is the operator’s responsibility to read and understand ALL Safety and Operating instructions in the manual and to follow these. Accidents can be avoided.

Working with unfamiliar equipment can lead to careless injuries. Read this manual, and the manual for your tractor, before assembly or operating, to acquaint yourself with the machines. It is the rotary cutter owner’s responsibility, if this machine is used by any person other than yourself, is loaned or rented, to make certain that the operator, prior to operating:

1. Reads and understands the operator’s manuals.

2. Is instructed in safe and proper use.

Know your controls and how to stop tractor, engine, and cutter quickly in an emergency. Read this manual and the one provided with your tractor.

Train all new personnel and review instructions frequently with existing workers. A person who has not read and understood all operating and safety instructions is not qualified to operate the machine. An untrained operator exposes himself and bystanders to possible serious injury or death.

Do not allow children to operate this machine.

SAFETY INSTRUCTIONS (continued)

Never operate the tractor and cutter until you have read and completely understand this manual, the Tractor Operator’s Manual, and each of the Safety Messages found on the safety signs on the tractor and cutter.

Clear area to be cut of stones, branches or other debris that might be thrown, causing injury or damage.

Operate only in daylight or good artificial light.

Ensure cutter is properly mounted, adjusted and in good operating condition.

Make sure driveline spring-activated locking pin or balls operate freely and are seated firmly in tractor PTO stub shaft groove.

Ensure that all safety shielding and safety signs are properly installed and in good condition.

Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended during assembly , installation, operation, adjustment, maintaining, repairing, removal, or moving the implement. Do not allow long hair, loose fitting clothing or jewelry to be around moving parts.

Operate the cutter only with a tractor equipped with an approved Roll-Over Protective System (ROPS). Always wear your seat belt on tractors equipped with a ROPS. Serious injury or even death could result from falling off the tractor ---particularly during a turnover when the operator could be pinned under the ROPS or the tractor.

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS!

Tractors with or without Cutters attached can often be noisy enough to cause permanent, partial hearing loss. We recommend that you wear hearing protection on a full-time basis if the noise in the Operator’s position exceeds 80db. Noise over 85db on a long-term basis can cause severe hearing loss. Noise over 90db adjacent to the Operator over a long-term basis may cause permanent, total hearing loss. NOTE: Hearing loss from loud noise (from tractors, chain saws, radios, and other such sources close to the ear) is cumulative over a lifetime without hope of natural recovery.

PREPARATION

SAFETY INSTRUCTIONS (continued)

STARTING

Cutter operating power is supplied from tractor PTO. Refer to your tractor manual for PTO engagement and disengagement instructions. Always operate PTO at 540 RPM. Know how to stop tractor and cutter quickly in case of an emergency.

When engaging PTO, the engine RPM should always be low. Once engaged and ready to start cutting, raise PTO speed to 540 RPM and maintain throughout cutting operation.

Check the tractor master shield over the PTO stub shaft. Make sure it is in good condition and fastened securely to the tractor. Purchase a new shield if old shield is damaged or missing. (You may have to use a tractor salvage yard for replacement parts on older tractors.)

All tractors that are not equipped with a “live” takeoff (PTO) need to be equipped with an over-running PTO clutch type driveline. These are available as optional equipment. See page 22.

NOTE: The addition of a separate over-running PTO clutch attachment will change the length of the PTO driveline. Pay extra attention to the instructions on PTO driveline installation.

AND STOPPING SAFETY

Separate over-running clutch attachments will increase the length of the driveline and may cause the front knuckle joint to operate beyond the cover of the tractor master shield. This is NOT recommended and will present a dangerous operating condition.

OPERATIONAL SAFETY

Most accidents occur because of neglect or carelessness. Keep all helpers and bystanders at least several hundred feet from an operating rotary cutter. Only properly trained people should operate this machine.

When this machine is operated in populated areas or in other areas where thrown objects could injure persons or property, standard equipment safety chain shielding (which is designed to reduce the possibility of thrown objects) must be installed. If this machine is not equipped with full chain shielding, operation must be

stopped when anyone comes within several hundred feet.

The majority of accidents involve entanglement on the driveline, injury of bystanders by objects thrown by the rotating blades, and operators being knocked off the tractor by low hanging limbs and then being run over by the cutter. Accidents are most likely to occur with machines that are loaned or rented to someone who has not read the owner’s manual and is not familiar with a rotary cutter.

SAFETY INSTRUCTIONS

(continued)

Always stop the tractor, set brake, shut off the tractor engine, remove the ignition key, lower implement to the ground and allow cutter blades to come to a complete stop before dismounting tractor. Never leave equipment unattended with the tractor running.

Never place hands or feet under cutter with tractor engine running or before you are sure all motion has stopped. Stay clear of all moving parts.

Do not reach or place yourself under equipment until it is blocked securely.

Take all possible precautions when leaving unit unattended: Disengage PTO, set parking brake, stop engine and remove key from ignition. Park in level area.

Do not allow riders on the rotary cutter or tractor at any time. There is no safe place for any riders.

Disengage power takeoff (PTO) and place transmission into neutral before attempting to start engine.

Do not operate unless all personnel, livestock, and pets are several hundred feet away to prevent injury by thrown objects. Never direct discharge toward anyone.

Install and secure all guards and shields before starting or operating.

Keep hands, feet, hair, and clothing away from moving parts.

This rotary cutter is designed for use only on tractors with 540 RPM power takeoff.

Never operate tractor and cutter under trees with low hanging limbs. Operators can be knocked off the tractor and then run over by the rotating blades.

The rotating parts of this machine have been designed and tested for rugged use. However, they could fail upon impact with heavy, solid objects such as steel guard rails, posts, and concrete abutments. Such impact could cause the broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the cutting blades to contact such obstacles.

Frequently check cutter blades. They should be sharp, free of nicks and cracks and securely fastened.

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the cutter head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous. Inspect the cutting area for such objects before mowing. Removing any like object from the site. Never allow the cutting blades to contact such items.

Pick up all rocks and other debris before mowing. Enter new areas carefully. Cut material higher at first, allowing cutter to clear hidden objects. Never assume an area is clear. Always Check!

OPERATIONAL SAFETY (continued)

SAFETY INSTRUCTIONS (continued)

OPERATIONAL SAFETY (continued)

Stop cutter and tractor immediately upon striking an obstruction. Turn engine off, remove key, inspect and repair any damage before resuming operation.

The chain guards, bands, flaps, driveline shields, and gearbox shields should be used and maintained in good working condition. They should be inspected carefully, at least daily, for missing or broken cable, chain links, shields, or guards. Missing broken, or worn items must be replaced at once to reduce the possibility of injury from thrown objects or entanglement.

Stay alert for holes, rocks and roots in the terrain and other hidden hazards. Keep away from drop-offs.

Use extreme care and maintain minimum ground speed when transporting on hillside, over rough ground and when operating close to ditches or fences. Be careful when turning sharp corners.

Reduce speed on slopes and sharp turns to minimize tipping or loss of control. Be careful when changing directions on slopes. Do not start or stop suddenly on slopes. Avoid operation on steep slopes.

When using a unit, a minimum 20% of tractor and equipment weight must be on tractor front wheels. Without this weight, tractor could tip over, causing personal injury or death. The weight may be attained with a front end loader, front wheel weights, ballast in tires of front tractor weights. When attaining a minimum 20% of tractor and equipment weight on the front wheels, you must not exceed the ROPS weight certification. Weigh the tractor and equipment. Do not guess or estimate!

Inspect the entire machine periodically as indicated in the Maintenance Section of this manual. Look for loose fasteners, worn or broken parts, pinched hydraulic hoses, and leaky or loose fittings. Make sure all pins have cotter pins and washers. Serious injury may occur from not maintaining this machine in good working order.

Be careful when operating tractor and cutter on uneven ground to avoid upsetting.

In extremely uneven terrain, real wheel weights, front tractor weight, and/or tire ballast should be used to improve stability.

Pass diagonally through sharp dips and avoid sharp drops to prevent “hanging up” tractor and cutter. Practice will improve your skills in maneuvering rough terrain.

Avoid sudden starts and stops while traveling up or downhill.

Always cut down slopes; never across the face. Avoid operation on steep slopes. Slow down on sharp turns and slopes to prevent tipping and/or loss of control.
