SAFETY PRECAUTIONS

Safety is the 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 is the operator’s responsibility to read and understand all safety and operating instructions in the manual and to follow these. Allow only properly trained personnel to operate the rotary cutter. 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, before operating, reads and understands the operator’s manuals and is instructed in safe and proper use.

WARNING:  Because of possible injury from thrown objects, all rotary cutters are potentially dangerous. Any rotary cutter intended for use along roadways or other locations where people may be present, must be used with safety shields in place.

WARNING:

1. Before operating equipment read and understand the operator’s manual and the safety signs (see Fig. 2).
2. Thoroughly inspect the implement before initial operation to assure that all packaging materials, i.e. wires, bands, and tape have been removed. Always ensure that tape has been removed from blades before use.
3. Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended during assembly, attachment, operation, adjustment, maintaining and/ or repairing of the implement.
4. Operate the rotary cutter only with a tractor equipped with an approved Roll-Over-Protective- System (ROPS). Always wear your seatbelt. Serious injury or even death could result from falling off the tractor.

Handles the tallest grass and can be used also for chopping wheat, cornstalks, sunflowers, artichokes, potatoes, etc. The residue is pulverized for easy incorporation.

WARNING:  Because of possible injury from thrown objects, all rotary cutters are potentially dangerous. Any rotary cutter intended for use along roadways or other locations where people may be present must be used with safety shields in place.

Operational Safety
CAUTION:  Our rotary cutters are designed considering safety as the most important target and are the safest available in today’s market. Unfortunately, human carelessness can override the safety features built into our machines. Injury prevention and work safety, aside from the features on our cutters, is very much due to the responsible use of the equipment. It must always be operated prudently following with great care, the safety instructions laid out in this manual.

1. The use of this equipment is subject to certain hazards which cannot be prevented by mechanical means or product design. All operators of this equipment must read and understand this entire manual, paying particular attention to safety and operating instructions, before using.
2. Do not operate the tractor and cutter when you are tired, sick or when using medication.
3. Keep all helpers and bystanders at least several yards from a rotary cutter. Only properly trained people should operate this machine.
4. When this machine is operated in populated areas where thrown objects could injure persons or property, optional equipment safety shielding (which is designed to reduce the possibility of thrown objects) must be installed.
5. The majority of accidents involve entanglements 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 operator’s manual and is not familiar with a rotary cutter.
6. Always stop the tractor, set brake, shut off the tractor engine, remove the ignition key, lower the implement to the ground and allow blades to come to a complete stop before dismounting the tractor. Never leave equipment unattended with the tractor running.
7. Never place hands or feet under cutter’s deck with tractor engine running or before you are sure all motion has stopped. Stay clear of all moving parts.
8. Do not allow riders on the cutter or tractor at any time. There is no safe place for riders.
9. Do not operate unless all personnel, livestock and pets are several yards away to prevent injury by thrown objects.
10. Before backing up, disengage the cutter and look behind carefully.
11. Install and secure all guards and shields before starting or operating.
12. Keep hands, feet, hair and clothing away from moving parts.
13. This rotary cutter is designed for use only on tractors with 540 rpm power take-off.
14. 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.
15. 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 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.
16. Frequently check blades. They should be sharp, free of nicks and cracks and securely fastened.
17. Stop cutter immediately upon striking an obstruction. Turn engine off, remove key, inspect and repair any damage before resuming operation.
18. Stay alert for holes, rocks and roots in the terrain and other hidden hazards. Keep away from drop-offs.
19. 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.
20. 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.
21. 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 or 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!
22. Inspect the entire machine periodically. Look for loose fasteners, worn or broken parts, and leaky or loose fittings.
23. Use only the driveline supplied with the equipment. Do not use it if it is missing any shield or safety protection.
24. Pass diagonally through sharp dips and avoid sharp drops to prevent “hanging up” tractor and implement.
25. Avoid sudden starts and stops while traveling up or downhill.
26. 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.

Set-up

Dealer notice:  Pre-delivery set-up and seNice including lubrication is the responsibility of the authorized dealer. It is up to him to assure that the machine is in excellent working condition and ready to be used. It is his responsibility to ensure that the customer is aware of all safety aspects and operational procedures for the cutter. He must also fill out the Pre-delivery checklist before delivering the cutter.

CAUTION:  Stand clear of bands when cutting as they could be under sufficient tension to cause them to fly loose. Take care in removing bands and wire, they often have extremely sharp edges and cut very easy.

Cutting Height Adjustment

WARNING:  Keep hands and feet away from moving blades. Be sure tractor engine is off, parking brake is locked, and key is removed before making any adjustments. Never rely on the tractor lift system. Install blocks or stands under the cutter deck to prevent it from falling. The cutting height is the distance from the blades to the ground which is determined by the position of the tail wheel. The cutting height is adjusted by moving the wheel arm up or down in the height adjustment brackets which are a part of the deck. Raising the wheel arm lowers the cut.
IMPORTANT:  Very low cutting heights should be avoided. Damaging shock loads occur when the blades strike the ground repeatedly. This can cause damage to the cutter.

Pre-Operational Check
Check each of the following carefully before engaging the equipment:

1. The spindle bearing has been greased.
2. The oil in the gearbox.
3. The driveline cross & bearings have been greased.
4. No wrappings or foreign objects are around the rotor, blades, or driveline.
5. The blades are properly installed and the blade bolts properly torqued.
6. All hardware is tight.
7. The tractor, to ensure correct direction of PTO and rpm speed.
8. All safety shields and guards are in their place and tightly attached.
9. No people or animals are in the work area.

WARNING:  Stay clear of the rotating driveline. Entanglement in a rotating driveline can cause serious injury. Disengage PTO, engage parking brake or place transmission in “Park”, shut off the tractor and remove the key before working around hitch, attaching or detaching the driveline, making adjustments, servicing or cleaning the machine.

Attaching to the Tractor
Only use this model implemented with tractors in the correct power range.

CAUTION:  Check the tractor PTO rpm and its direction of rotation to ensure that they correspond to what is indicated on the machine.
WARNING:  Disengage PTO, wait for all movement from the implement and tractor to stop, engage parking brake or place transmission in “Park”, shut off the tractor and remove the key before attaching the implement to the tractor.
DANGER:  Tractor-implement combinations can create unstable unions with a chance of rollover. If necessary, front weights need to be added to the tractor to maintain balance. Always ensure that the tractor tire pressure is correct according to the tractor operator’s manual.

To attach the cutter to the tractor do the following:

1. Back the tractor up to the machine to slip the tractor hitch arms over the hitch pins bolted to the cutter hitch arms. Turn off the tractor engine. Secure them in place with the lynch pins. Failure to ensure a secure coupling of the implement to the tractor can cause personal injury and damage to the implement or tractor.
2. Adjust the tractor sway blocks or chains to remove all side movement.
3. Attach the top link. Adjust tractor top link to allow the cutter to follow the ground contour and yet remain as level as possible when raised to transport position.
4. Install the shielded driveline to the tractor by first lining up the splines and depressing the snap pin. Push the yoke onto the PTO shaft as far as it will go. Release the pin and pull back slowly until the pin clicks in place. Repeat this operation on the implement end.
5. Attach the driveline chains to the tractor and to the machine to keep the driveline protection from turning. The chains should not be too tight.

Start-Up
CAUTION:  The cutter must always be lowered to the ground before starting tractor engine or engaging PTO lever. Lower the implement with the tractor rock shaft control lever until the deck is horizontal to the ground. If the cutting height is not correct, change the setting using the tail wheel. The deck should be horizontal to the ground when cutting. With the engine idling, slowly engage the PTO  drive. Move the throttle lever until the PTO speed indicated on the cutter is obtained. The machine is normally set for a PTO speed of 540 rpm. Other special versions are available,upon request, for other speeds. Shift the transmission to a slow-speed gear and start forward, increase the ground speed by shifting upward until the desired speed is obtained. Do not mow in reverse unless necessary and only after careful observation of the area behind the rotary cutter.

CAUTION:  Do not operate this implement at a PTO speed or direction of rotation other than that shown on the cutter. Serious damage can occur to the machine  and/or the operator

Before starting to mow, never forget that the operator is responsible for the following:

1. Safe and correct driving of the tractor and cutter.
2. To learn precise safe operating procedures for both the tractor and the cutter.
3. To ensure all maintenance and lubrication has been performed on the cutter.
4. To have read and understood all safety aspects for the cutter in the operator’s manual.
5. To have read and understood all safety decals on the machine.
6. Checking the condition of the blades. Worn or damaged blades should be changed before starting.
7. Checking to ensure that the cutting edge is the leading edge of the blade.
8. Check that there is no wire, weed, grass or other material wrapped around the blades.
9. Checking to see if front weights need to be added to the tractor to maintain balance.
10. Checking the tractor tires for the proper pressure by the tractor operator’s manual.
11. Check that the PTO shield and all other shielding are on the machine and securely in place.
12. Make sure the proper attire is worn. Avoiding loose-fitting clothing which can become entangled. Wearing sturdy, tough-soled work shoes and protective equipment for eyes, hands, ears and head. Never operate tractor or implement in bare feet, sandals or sneakers.
13. Checking area for stones, branches, and other debris that might be thrown.
14. Ensuring proper lighting is available, sunlight, or good artificial lighting.

Working Speed
The mowing speed depends on ground conditions, tractor HP, mowing height, and grass thickness. Only a test run will enable you to gauge the optimal working speed for your conditions. Under most conditions, a 2 to 6 mph ground speed is best. To obtain the best cut possible, always keep the tractor rpm up to the speed indicated on the cutter. When increasing or decreasing mowing ground speed, always use gear selection, not engine speed. This will maintain the constant maximum blade speed necessary for a clean cut.

WARNING:  Never operate without all shields on the machine and securely in place. The cutter blades can throw objects hundreds of feet which could result in personal or property damage. Pick up all rocks and other debris before mowing. Enter new areas carefully. Cut grass higher at first, allowing the machine to clear hidden objects.
CAUTION:  For emergency reasons learn how to stop the tractor and cutter quickly. On the Tornado rotary cutter always disengage the PTO, lock parking brake, stop engine and allow the blades to come to a complete stop before dismounting the tractor.

Uneven Terrain
WARNING:  Be careful of roll-over when operating the tractor and cutter over uneven ground.
In extremely uneven terrain rear wheel weights, front tractor weights, and/or tire ballast should be used to improve stability. When mowing over uneven terrain, observe the type of terrain and develop a safe mowing pattern. Whenever traction or stability is doubtful, first test drive over the terrain with the PTO disengaged. Operate the cutter up and down steep slopes, not across slopes, to prevent the tractor from tipping. Avoid sudden stops and starts and slow down before changing directions on a slope.  Pass diagonally through sharp dips and avoid sharp drops to prevent hanging up the tractorSlow down on sharp turns and slopes to prevent tipping or loss of control. Avoid tipping the cutter while cutting. Watch for holes, roots or other hidden objects. Do not cut near the edge of a gully, ditch or stream bank.

Removing Cutter from the Tractor

CAUTION:  Disengage tractor PTO. Set parking brake. Stop engine and remove key from ignition. Disconnect cutter driveline from tractor PTO shaft. Collapse driveline and secure it in a safe place. Disconnect three point linkage and carefully drive tractor away from cutter.

MAINTENANCE

DANGER:  Stop engine, lock parking brake and remove key before performing any service or maintenance. Never rely on the tractor lift system. Install blocks or stands under the cutter deck to prevent it from falling. Always use personal protection devices, such as glasses or gloves when performing maintenance. Keep fingers out of slots to prevent injury.

Maintenance Safety

1. Good maintenance is your responsibility.
2. Keep service area clean and dry. Be sure electrical outlets and tools are properly grounded.Use adequate light for the job at hand.
3. 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.
4. Make no repair or adjustments with the tractor engine running. Before working on the machine, disengage the PTO, shut off the engine, set the brakes, and remove the ignition key.
5. Be certain all moving parts on the attachment have come to a complete stop before attempting to perform maintenance.
6. Never work under equipment unless it is blocked securely.
7. Always use personal protection devices such as eye, hand and hearing protectors, when performing any service or maintenance.
8. Frequently check blades. They should be sharp, free of nicks and cracks and securely fastened.

Service
The accompanying illustrations show lubrication points. The chart gives the frequency of lubricationin hours, based on normal operating conditions. Severe or unusual conditions may require more frequent lubrication. Use a good quality SAE multipurpose type grease for all locations shown. Be sure to clean fittings thoroughly before using grease gun.  Use 90 wt. 140 wt. gear oil in gearbox

Hourly:

1. Check the condition of cutter blades for nicks or dull edges.
2. Sharpen if necessary. Replace bent or damaged blades.
3. Also check blades for damage after hitting an obstruction.
4. Clean foreign material from the deck.

Every 8 hours:

Lubricate driveline, lubricate caster wheel and tail wheel arm (see fig. 3 & 4): apply two or three shots of grease to the driveline cross and bearings and the telescoping shafts; apply the same amount to the wheel arm grease fittings and the wheel grease fittings.

• Gearbox oil level:  check the gearbox oil level, it should be between 1/2 and 2/3 full. If needed add either SAE 90 wt. or SAE 140 wt. gear oil.

Every 25 hours:  check hardware tightness. Cutter vibrations can loosen bolts Check tightness of the hardware periodically.

Blade Maintenance
WARNING:  Avoid possible injury, wear proper eye and hand protection when servicing cutter blades.
Proper blade maintenance is important in order for the cutter to work properly, to always obtain a precision cut and to lower HP requirements thus keeping costs down. Blades must be kept sharp, at their original length and with corners intact. A blade must be replaced if, due to wear or damage, its original shape has been distorted. Blade sharpening is extremely important to get the best cutting results.

Removing or installing blades
Never rely on the tractor lift system to support the machine while working underneath. Install blocks or stands under the cutter deck to prevent it from falling.
In any case, proceed as follows (see fig. 5):

1. Remove the top inspection plate to gain access to the rotor.
2. Block the blade carrier rotor with a wrench and remove the blade bolt nut.
3. Remove the blade bolt and blade.
4. Check the bolt for wear. Replace if necessary.
5. Place the new blade making sure that the cutting edge is towards the direction of rotation. The blade turns in a clockwise direction when viewed from the bottom of the deck
6. Insert the blade bolt into the new blade and install into blade carrier rotor. Ensure the blade bolt pin is seated into the rotor properly.
7. Properly torque the nut to 360 N.m. (250 lb.ft.).

IMPORTANT:  Check blade bolt torque every 8 hours. Ensure the blades are able to freeze. This is extremely important to prevent damage to the cutter.
IMPORTANT:  When installing new blades, it is important that they be the same and the same weight to ensure balance. An unbalanced rotor blade carrier can damage the cutter.
WARNING:  Do not substitute blades or any bolt for the blade retaining bolt. Company blades and blade retaining bolts are specially made for this application. Using nonoriginal parts can effect the quality of cut and may also cause damage to the machine.
DANGER:  Proper torque must be used when tightening the blade retaining bolt. If these safety precautions are not followed, the blade could come off during operation and be thrown hundreds of feet from the cutter.

Driveline

DANGER:  Only use the original driveline supplied with this machine and always keep me safety shielding installed and working properly.
CAUTION:  In the collapsed position the driveline should be approximately 2″ from bottoming out to prevent possible damage to the tractor or implement. When the PTO is in the maximum extended position, the ideal minimum overlap of the two halves should be approximately 6″ (see Fig. 6).

If determined that the driveline is too long. Follow these procedures to adjust the length:

1. Separate the two driveline halves. Connect one half to the tractor PTO and the other half to the cutter.
2. Raise and lower the machine with the 3 point hitch to find the position where the driveline is shortest. Hold the half shafts side by side and mark the desired length on the outer female guard tube leaving a 2″ gap between the end of the guard tube and bell guard.
3. Cut off both guard tubes the same amount as marked in step 2.
4. Shorten both drive tubes the same amount as guard tubes.
5. De-burr and clean filings from drive tubes and apply grease to outside of inner telescoping tube.

Reassemble the driveline halves and connect to tractor and cutter. Raise and lower cutter again to be sure driveline does not bottom out in shortest position and has a minimum overlap of 6″ in the longest position.

CAUTION:  Always work with the driveline as straight as possible. This will prolong its life and that of its components. It is advised, not to work at an angle greater than 15 degrees.

Safety Slip Clutch
When the cutter is supplied with a safety slip clutch, it is important to ensure it is working properly. The slip clutch delivered with your machine is set at a specific torque for normal working conditions. If while working, the clutch slips frequently, the spring nuts need to be tightened 1/2 turn. Check the clutch after 600-800 ft., if necessary repeat the operation. If after tightening the nuts down and the clutch continues to slip, the discs will have to be replaced (see fig. 7). Follow the instructions in reverse, if while working under normal conditions the clutch does not slip at all.

Transport
Before raising the mower for transport, the tractor top link must be adjusted so when lifted, the rear of the machine is higher than the front (the mower’s nose is tilted downward). To do this, shorten the tractor top link until the top hitch plate is locked forward and no longer able to pivot. This will keep the mower locked in position and minimize the shaking and bouncing during transport  which can damage the hitch or frame. When raising the mower be sure the PTO driveline does not hit either the mower or the tractor. During transport the mower should not be lifted over 14″-16″ from the ground.

CAUTION:  Make sure PTO is disengaged and blades have stopped turning before raising cutter to full transport position. Do not tow tractor and cutter behind other vehicles. Use a properly equipped trailer with heavy tie- downs for towing operations.

To transport, do the following:

1. Disengage PTO.
2. Shorten tractor top link until top hitch plate is locked.
3. Raise machine and lock rockshaft control lever.
4. Always select a safe ground speed that is appropriate for the terrain.
5. Beware of traffic on public roads. Install a SMV (Slow Moving Vehicle) sign when traveling on roads or streets.
6. Reduce ground speed when turning and take care that the cutter does not strike obstacles such as trees, fences or buildings.

DANGER:  Always stay clear of rotating driveline and blades when the PTO is engaged.
WARNING:  Disengage the PTO, apply the parking brake, shut off the engine and remove the key before attaching or removing the driveline, or performing any maintenance or adjustments on the machine.
