SAFETY
ALLOWED USE:
AG flail mowers, as described in this instruction and maintenance booklet, have been
specifically designed to mow grass, weeds, and light brush up to 1" diameter. Any
other use jeopardizes the operator's safety and the machine integrity.
IMPROTER USE:
The mower was designed to mow grass, weeds, and light brush only. Only operate
this mower on a properly sized and equipped tractor.
When using AG flail mowers, it is particularly forbidden:
-The attachment to tractors of unsuitable power or weight.
-To use other than 1000 R.P.M. PTO speed.
-To work in excessively stony grounds.
-To work on excessive slopes.
-To approach the machine when wearing inappropriate works clothing.
-To get on the machine while it is being used or transported.
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
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 action by constantly paying attention to its
effects.
If potentially dangerous situations are known, accidents can be
prevented!
OPERATOR'SREQUIREMENTS:
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 eventual 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.
-Protective gloves for hands.
-Protective glasses or faceplate to protect eyes and face.
-Protective helmet for the head.
-Safety shoes
Wear only personal safety
accessories in good condition and

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, maybe during a critical movement.
-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 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 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 out 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, even if
just for fun.
-Watch out for those who are present, especially the 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.

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 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 a flat and smooth ground
and make sure that nobody is standing between
them.
Move slowly 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.
Connect first the lower arms by removing the release pins of the brackets placed on the
plates, inserting the lift arms into the arms center and fasteningthem with the relevant
release pins, which had been removed.
Connect, then, 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.

Ha
H a n m e y I m p l e m e n t s
12
SET UP
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 stresses on the power takeoff and extending the working life of the
equipment.
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 front tires or add front weights.
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).

SET UP
DRIVELINE ATTACHMENT
Before assembling the PTO shaft, check out 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.
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 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
driveshaft 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.

SET UP
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 far 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 hang 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 the blades dont impact the ground in operation.
- 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 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

SET UP
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 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 quality, diameter and height of the material to be cut;
anyway, 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.
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 a 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 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 out 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
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 on 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.
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 takeoff, set
parking brake and place the
equipment on the ground in
horzontal position.
- After the first working hours, check
that all bolts and nuts are tightened;
remember also to check often all the
machine safety guards.

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 turn freely on the shaft at all times. Annual disassembly, cleaning and
lubrication is recommended to insure 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.
