DANGER
Operating this mower in an application for which it is not designed and/or operating with the wrong size tractor can cause mower component damage and equipment failure resulting in possible serious injury or death.

SAFETY IN THE WORKPLACE:
Most of the accidents which take place while the operator is using the machine or the equipment or during their maintenance or repair are caused by a lack of compliance with the basic safety precautions. It is necessary, therefore, to become more and more conscious of the potential risks of one’s actions by constantly paying attention to the effects.
If potentially dangerous situations are known, accidents can be prevented!

OPERATOR’S REQUIREMENTS:
Physical: good eyesight, coordination and capability of carrying out all functions required for the machine’s use.
Mental: Capability of understanding and applying the established rules and safety precautions. Users must pay attention and be sensible for their own and other people’s safety.
Training: users must have read and studied this manual, its enclosed graphs and schemes and its identification and danger plates. They must be skilled and trained on any use or maintenance activities.

WORK CLOTHING:
When working and especially when executing repair or maintenance activities, it is necessary to wear the following clothing and safety accessories:

• Overalls or other comfortable clothing, not too loose to prevent the possibility that parts of them might be caught in the moving parts of the machine.
• Protective gloves for hands.
• Protective glasses or faceplates for eyes and face.
• Protective helmet for the head.
• Safety shoes.

Wear only personal safety accessories in good condition and comply with the rules in force.

GENERAL SAFETY RULES

ALWAYS CONSIDER THE FEATURES OF THE AREA WHERE WORK IS TAKING PLACE:
When the equipment is running, it is forbidden to stand within the field of action of the shredder or of the other accessories of which it is provided with.

PREPARE THE WORK:

• Before and when working, do not drink alcohol, take drugs or any other substances which may alter your capability of working with machine tools.
• Be sure to have sufficient fuel to prevent a forced stopping of the machine, especially during critical operations.
• Do not use the equipment under unsafe conditions. For instance, it is forbidden to execute makeshift repair activities just to start working; it is forbidden to work at night with an insufficiently illuminated working area.
• NEVER operate implement without all shields in place and in good operational condition. The operator must be familiar with the mower and tractor and all associated safety practices before operating the mower and tractor.

WHEN WORKING OR DURING THE MAINTENANCE ACTIVITIES IT IS NECESSARY TO REMEMBER:

• The labels and stickers providing instructions and pointing out the dangers must not be removed, hidden, or made illegible.
• Do not remove, except in case of maintenance, the shields, guards, and deflectors equipped on the mower. When it is necessary to remove them, stop the engine, handle with care and reassemble them properly before restarting the engine and using the equipment. The mower is equipped with protective deflectors to prevent objects from being thrown from the mower by the blades, however, no shielding is 100% effective. All shields, guards, and deflectors equipped on the mower must be maintained in good operational condition.
• It is forbidden to lubricate, clean, and adjust the moving parts while they are running.
• During maintenance or adjustment activities on the equipment, it is forbidden to use hands for executing operations for which there are specific tools.
• Do not use tools in bad condition or inappropriately, for instance, pliers rather than monkey spanners, etc.
• When maintenance or repairs are completed, check that no tools, wiping rags, or other materials are left inside spaces or guides with moving parts.
• While using the equipment, it is forbidden to make more than one person give directions and make signals. The eventual directions and signals relating to the load handling must be given by one person only.
• Do not unexpectedly call an operator while he is working if not necessary; it is forbidden as well to frighten or throw objects at the operator.
• Watch out for bystanders, especially children!
• Do not make people get on the machine.
• When the equipment is not needed, stop the vehicle’s engine, park it on flat ground with first speed and parking brake on, with the machine rested on the ground and PTO disengaged.
• Do not clean, lubricate, repair or adjust with the engine running and the machine lifted.
• Never use the machine on steep slopes which may jeopardize the equipment’s stability. The manufacturer declines all responsibility for a lack of compliance with these instructions.

SET UP

ATTACHMENT TO THE TRACTOR
Before operating the mower, carefully read this Operator’s Manual, completely understand the safety instructions, and know how to operate both the tractor and the PTO shaft correctly, carefully reading the instruction manuals of the tractor and PTO shaft manufacturers.
All AG flail mowers have been manufactured to be attached to any tractor provided with a hydraulic and universal 3-point hitch.
The tractor used to operate the mower must have the power, capacity, and required equipment to safely operate the mower. Operating the mower on improperly sized and equipped tractors may cause tractor and/or mower damage and could be a potential danger to the operator and passers-by.
Before attaching the implement to the tractor, set both on flat, smooth ground and make sure that nobody is standing between them.
Move the tractor slowly towards the flail mower by aligning the tractor hydraulic lift arms to the two mower hitches’ lateral brackets; stop the engine and set the parking brake.
Connect the lower arms first by removing the release pins of the brackets placed on the plates, inserting the lift arms into the arms center, and fastening them with the relevant release pins, which had been removed. Then connect the tractor top link to the third upper point by removing the pin located between the plates, inserting the top link itself and locking it with the pin.

Adjust the third point so that the upper part of the frame is parallel to the ground. Lock all connection parts with the special sway chains or tie rods.

It is always good to make sure that the central gearbox axis is parallel to the ground, thus reducing the stress on the power takeoff and extending the working life of the equipment.
DANGER
Pay attention to the tractor’s front wheels grip when the equipment is set up and lifted; if the wheels appear to be too lightened, ballast the tractor’s front tires or add front weights.
CAUTION
After executing the above-mentioned activities it is always good to check that all bolts and nuts of your shredder are tightened (refer to the torque specifications in this manual).

DRIVELINE ATTACHMENT
Before assembling the PTO shaft, check that its RPM and direction of rotation match those of the tractor. Moreover, carefully read the instruction manuals of the PTO shaft and the tractor manufacturers. Before starting work, make sure all safety shields are in place. Check-in is particular that the safety guards cover the PTO shaft throughout its extension. When attaching the mower input driveline to the tractor PTO, be sure that the connecting yoke spring activated locking collar slides freely and the locking balls are eaten securely in the groove on the tractor PTO shaft. A driveline not attached correctly to the tractor PTO shaft could come loose and result in personal injury and damage to the implement.

CAUTION
Make sure the driveline will not bottom out (at its most compressed position there must be at least a 3/4” clearance between each profile end and opposite profile universal joint) or become disengaged (at its farthest extended position a minimum profile engagement of 1/3 of the length must be maintained). Check that the Cardan shaft minimum and maximum length are the ones required by the machine-tractor coupling. Should problems arise, contact a skilled repair shop or the driveshaft retailer. After installation, secure safety guards to the tractor and the machine using the special chains and make sure that they pivot freely. If the PTO shaft is equipped with other safety devices, such as a pair limiter or freewheels, be sure to install them on the machine side. For PTO use and maintenance, refer to the relevant booklet.

WORKING HEIGHT ADJUSTMENT
The machine’s working height is determined by the position of the rear roller. Lifting the roller moves the cutters closer to the soil, whereas lowering it moves the cutters farther from the soil. After a modification of the working height, be sure that the cutters skim the ground; direct contact would cause wear and could affect the cutting rotor balance, and may cause objects to be thrown out from under the mower deck.

FLAIL MOWER ADJUSTMENT

1. On a flat piece of ground, attach the flail mower to the tractor using the three-point linkage.
2. Use a solid adjustable top link.
3. Lower the three-point linkage to its lowest position.
4. With the roller at the rear in contact with the ground, adjust the length of the top link so that the lower edge at the side of the flail mower is parallel with the ground.
5. Rotate the blade drum by hand so that a row of blades hangs vertically towards the ground.
6. Measure the clearance between the bottom of the extended blades and the ground.
   • Minimum 50mm
   • Note: in rough or lumpy paddocks the clearance needs to be increased to ensure that the blades don’t impact the ground in operation.
7. Adjust the roller height to increase or decrease the blade clearance as required
8. Go through steps 4-7 until the required clearance is achieved.

When the Flail Mower has been set up with the required tolerances: Operate the Flail Mower with tractor in low range and the PTO delivering 1000 RPM.
DRIVE BELT ADJUSTMENT
Loosen Screws A and B that lock the support shaft and loosen the counter nut C.
Loosen the screws that lock the gear box on the mounting plate D.

Adjust the drive belt tension. The correct belt tension is achieved when the belt can be deflected by the belt thickness about 10mm at the center point between the pulleys.
Align the gearbox so the drive shaft is parallel with the body. Use a straight edge to make sure the belt pullies are inline and running true. If misaligned, call your dealer or
service agent for technical support.
Fit the safety covers and tighten the mounting bolts before operation.

TRANSPORT & STORAGE

WORKING SPEED
The working speed depends on the quality, diameter, and height of the material to be cut; for efficient mower performance, it must be between 2 and 5 MPH. The power takeoff speed must be 1000 RPM maximum. Operate the mower at its full-rated PTO speed to maintain blade speed for a clean cut.
DANGER
Do not exceed the rated PTO speed for the implementation. Excessive PTO speeds can cause driveline or blade failures resulting in serious injury or death.
ROAD TRANSPORT
Extreme caution should be used when transporting the tractor and implemented on public roadways. The tractor must be equipped with all required safety warning features including an SMV emblem and flashing warning lights which are clearly visible from the rear of the unit. Make sure you are in compliance with all local regulations regarding transporting equipment on public roads and highways. Do not exceed 20 MPH (32 kph). Reduce speed on rough roads and surfaces. Always use hazard flashers on the tractor when transporting unless prohibited by law.

STORAGE
If your shredder will not be used for a long period of time, respect the following suggestions:

1. Wash the machine thoroughly and dry it.
2. Lubricate all bearings with enough grease to eliminate any cavities where water condensation may occur and cause damage. Refer to “Maintenance of the Machine” for the location of all grease fittings. Be sure the vent on top of the gearbox is open.
3. Loosen the set nut and spindle jack to relieve drive belt tension (NOTE: Before next season’s use, be sure to adjust the drive belt tension.)
4. Coat all exposed surfaces inside the mower with oil or grease to prevent rusting and pitting during storage.
5. Protect the whole machine with a tarpaulin and store it in a dry place.

PRE-SEASON CHECK

1. Check the oil level in the gearbox and lubricate all bearings. See “Lubrication.”
2. Adjust drive belt tension. See “Belt Drive.”
3. Check all equipment and replace damaged or worn parts.
4. Tighten all bolts and nuts. See “Torque Specifications.”
5. Inspect for missing and/or broken blades/knives. Replace as necessary. See “Knife Replacement.”
6. Be sure that the safety guards are in place and secure.
7. Run the flail mower at a low RPM checking to make sure that all driveline parts are moving freely.

MAINTENANCE

Maintenance is a fundamental operation to extend the life and performance of any agricultural vehicle; taking care of the machine grants you not only proper efficiency and execution but also a longer life of all the equipment and greater safety of the workplace.
The operating times indicated in this manual have just an informative character and refer to normal conditions of use; they can thus undergo variations according to the type of service.

CAUTION
Before injecting lubricating grease into the zerks, clean them thoroughly to prevent mud, dust, or other foreign matters from mixing up with grease, thus diminishing the lubrication effect.

• When adding or changing oil, it is better to use the same oil type, in order to avoid mixing oils with different features.
• Before executing maintenance activities on the machine, stop the engine, disengage the power takeoff, set the parking brake and place the equipment on the ground in a horizontal position.
• After the first working hours, check that all bolts and nuts are tightened; remember to also often check all the machine safety guards.

FIRST CHECK

• Check the correct tension of the driving belt.
• Check that all bolts and nuts are tightened.
• After the first 50 hours of work, change oil in the gearbox.

EVERY 8 HOURS OF WORK

• Rotate teardrop-shaped plate B and grease the shaft support (driveline side) by lubricating nipple A (picture 1).
• Grease the shaft support (the external side) by lubricating zerk A (picture 2).
• Grease the shaft support (driveline) and the belt tensioner idler pin through lubricating zerks A and B (picture 3).
• Grease the stabilizing roller through lubricating zerk A (picture 4).

EVERY 50 HOURS OF WORK

• Check the tension of the driving belt.
• Check that all bolts and nuts are tightened.
• Check the cutters/hammers for wear.
• Check the overseas unit oil level through plug A (picture 5).

EVERY 500 HOURS OF WORK

• Check that all bolts and nuts are tightened.
• Change oil in the overseas unit.

EVERY 1000 HOURS OF WORK
Replace the driving belt.

GEARBOX MAINTENANCE

• The oil should be drained out and replaced after the first 50 hours of operation. Then the oil should be changed every 250 hours, or at least once a year.
• Drain the oil from the gearbox thoroughly. Check and clean it. Fill with new gear oil up to the dedicated oil level.
• The draining procedure is as follows: remove the draining bolt under the gearbox so that the oil drains off. After the oil is drained, put the plug back and fill with gear oil up to the dedicated oil level.

PTO SHAFT MAINTENANCE
The PTO shaft is designed to telescope to allow for dimensional changes as the machine goes through its operating range. A tubular guard encloses the driving components and is designed to turn relative to the driving components. The shaft should telescope easily and the guard should turn freely on the shaft at all times. Annual disassembly, cleaning, and lubrication is recommended to ensure that all components function as intended. To maintain the shaft, follow this procedure:

1. Remove the shaft from the machine.
2. Pull shaft apart.
3. Use a screwdriver to pry the tabs out of the sleeves on each end.
4. Pull the shaft out of the plastic tubular guard.
5. Use a solvent to clean the male and female portions of the telescoping ends.
6. Apply a light coat of grease to each end.
7. Clean the grooves on each end where the tabs are located. Clean each tab also.
8. Apply a light coat of grease to each groove.
9. Insert the shaft into its respective guard and align the slots with the groove.
10. Insert the tabs through the slots and seat in the groove.
11. Check that each guard turns freely on the shaft.
12. Assemble the shaft.
13. Check that the shaft telescopes easily.
14. Replace any components that are damaged or worn.
15. Install the shaft on the machine.
