• Never use the machine on steep slopes which may jeopardize the equipment’s stability. The manufacturer declines all responsibility for lack of compliance with these instructions.

ASSEMBLY

ATTACHMENT TO THE TRACTOR:

Before operating the mower, carefully read this Operator’s Manual, completely understand the safety instructions and know how to operate correctly both the tractor and the PTO shaft, reading carefully 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 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 equipment to the tractor, set both on flat and smooth ground and make sure that nobody is standing between them.
Slowly move the tractor towards the flail mower by aligning the tractor hydraulic lift arms to the two mower hitches’ lateral brackets; stop engine and set parking brake. First connect the lower arms 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 connections 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 stresses on the power take-off and extending the working life of the equipment.

DANGER!
Pay attention to the tractor’s front wheel grip when the equipment is set up and lifted; if the wheels appear to be too lightened, ballast the tractor 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 strongly (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, read carefully the instruction manuals of the PTO shaft and the tractor manufacturers. Before starting work, make sure all safety shields are in place. Check in 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 seated 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 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 out 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 drive shaft retailer. After installation, secure safety guards both 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. As for the 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, the cutters get close to the soil, whereas lowering it, the cutters get further from it. After a modification of the working height be sure that the cutters skim the ground; a direct contact with it would cause their wear and this could affect the cutting rotor balance and may cause objects to be thrown out from under the mower deck.

FLAIL MOWER ADJUSTMENT

• On a flat piece of ground, attach the flail mower to the tractor using the three point linkage.
• Use a solid adjustable top link.
• Lower the three point linkage to its lowest position.
• 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.
• Rotate the blade drum by hand so that a row of blades hangs vertically towards the ground.
• 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 blades don’t impact the ground.
• Adjust the roller height to increase or decrease the blade clearance as required.
• Go through steps 4 to 7 until the required clearance is achieved. When 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 the Screw A and B that locks 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 in-line and running true. If mis-angled, call your dealer or service agent for technical support. Fit the safety covers and tighten the mounting bolts before operation.

TRANSPORT

WORKING SPEED

The working speed depends on quality, diameter and height of the material to be cut; for efficient mower performance it must be between 2 and 5 MPH. The power take-o_ 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 implement. 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 implement on public roadways.
The tractor must be equipped with all required safety warning features including 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 regardingtransporting equipment on public roads and highways. Do not exceed 20 MPH (32KPH).
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 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 put 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. 7. Run the flail mower at low RPM checking to make sure that all driveline parts are moving freely.

MAINTENANCE

Maintenance is a fundamental operation to extend life and performances of any agricultural vehicle; taking care of the machine grants you not only a good work execution, but also a longer life of the whole equipment and a greater safety in the workplace. The operating times indicated in this manual have just an informative character and are referred 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 accurately 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 engine, disengage power take-off, set parking brake and place the equipment on the ground in horizontal position.
