2. Designed purpose of use
This AVANT flail mower is an attachment suitable for use with AVANT multi purpose loaders. Flail mower is a
cylinder type cutter, and it is intended for cutting of long grass, scrub, bush and similar vegetation. The use of
the flail mower is possible at areas where there are tree branches of up to 20 mm thick.
The flail mowers are equipped with a floating system, which allows the mower to follow the ground surface so
that the loader boom floating is not necessary. Furthermore, the blades on the flail mower shaft move freely,
so in case they hit a solid obstacle, such as rocks, ground, tree stumps etc., the blades will give in rather than
break. This saves blade costs when operating at uneven on unfamiliar areas.
Flail mower is the optimal cutting device for places where a lot of cutting power is needed and a rougher cut
will do. The most common grounds for flail mowers are places with taller vegetation like meadows, road
banks, yard areas etc., which are not accessible with ordinary lawn mowers or where the power of a lawn
mower is not sufficient. The mower can be equipped with different types of blades, consult your dealer for
more information.
The attachment has been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and
maintenance operations are to be left for professional maintenance. All maintenance work must be done using
proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by
using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT retailer if you have additional questions about the operation or maintenance of the equipment, or if
you require spare parts or maintenance services.
Table 1 - Flail mower - Compatibility with Avant loaders
When using with models marked with (), full performance may not be achieved. Additional counterweights
may also be required. For compatibility with a model not shown in table, contact your Avant dealer.
6 (26)
Misuse, careless use, or using an attachment that is in poor condition, may cause
risk of serious injuries. Familiarise yourself with the controls of the loader, correct
coupling procedure, and the correct way to operate the attachment at a safe area.
Study especially how to stop the equipment in a safe manner. Read all safety
precautions carefully.
When attaching an attachment to the loader, ensure that the locking pins of the
loader's quick attach plate are in the lower position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.
The Flail mower is designed to be used by one operator at a time. Do not let others
near the danger area of the equipment when it is in use.
Always transport the attachment as low as possible to keep the centre of gravity low,
and keep the telescopic boom retracted during driving.
Impact hazard - thrown objects. Do not let bystanders stand near the machine. Stop
the attachment if others get closer 5 metres from the attachment.
Severing and crushing hazard - sharp and strong blades rotate at high speed. Use
the mower only while lowered against the ground. Stop if others are present at
working area. Use only if all covers in place.
Never leave the driver’s seat when the flail mower is running or if the auxiliary
hydraulics control lever is locked on. The blades of the flail mower move for a short
period after the hydraulic supply has been shut off. Wait until the blades have
stopped completely before going near the machine
Be sure not to tilt the flail mower too far up, since this can make it swing over onto the
loader boom as the floating mechanism allows the flail mower to move. Keep the flail
mower at a low height.
Hazard of entanglement - Rotating parts. Stop the equipment following the safe
stopping procedure and lower the attachment firmly on the ground before leaving the
driver’s seat, or when other persons are present at the working area.
Keep hands and feet away from moving components. Wearing loose clothes, such as
loose shoelaces, or long scarves, should be avoided when working with the
attachment.
Stop the attachment by following the safe stopping procedure before going near the
attachment or the loader boom.
Always transport the attachment as low and close to the machine as possible to keep
the centre of gravity low. On slippery surfaces drive slowly and deliberately. Operate
the controls of the loader slowly and calmly especially on inclined terrain.
3. Safety instructions for using the attachment
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful and improper or careless use or maintenance may cause serious personal injury or property
damage. Due to this, all operators must carefully familiarise themselves about correct use and the operator's
manuals of both the loader and the attachment before starting operation. Do not use the attachment if you
have not completely familiarised yourself with its operation and the related hazards.
Read all safety instructions carefully before handling the attachment
7 (26)
Do not leave the driver’s seat when the loader boom is lifted. Going under a raised
attachment or loader boom is dangerous. Always remember that the boom may lower
due to loss of stability, mechanical fault, or if another person operates the controls of
the loader.
Use the attachment only for its intended use and only with original tools and spare
parts.
Shut down the loader and place the attachment to a safe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Pay attention to the contours of the terrain and other hazards, such as
branches and trees that can reach to the driver's area, loose rocks, and slippery
surfaces.
Make sure to use only an attachment that is in good condition. Do not modify the
attachment in any way that could affect its safety.
Use the attachment only for its intended purpose. Other use may create unnecessary
safety risks, and the equipment may get damaged.
Make sure that the loader is equipped with necessary safety components, and that
they are in working condition. Seat belt must be used. If there are specific hazards
related to the operating area, use appropriate safety equipment.
Also read the safety instructions and correct use of the loader from the operator's
manual of the loader.
Never allow anyone to get under the raised load or the loader boom. Keep in mind that the
loader boom can be lowered or tilted even if the engine has been shut down (crushing
hazard). The loader is not intended to be left to keep a load elevated for longer periods.
Always lower the attachment to a safe position before leaving the driver's seat.

Remember to wear proper protective clothing:
The noise level at the driver's seat may exceed 85 dB(A). Wear hearing
protection while working with the loader.
Wear protective gloves.
Wear safety boots whenever working with the loader.
At some areas or surfaces the brush may throw debris. Wear safety glasses.
Wear safety glasses when handling hydraulic components.
.
..
Always stop the attachment following safe stopping procedure before leaving the
driver's seat. Safe stopping procedure prevents all unintentional movements of the
attachment. Note that the loader boom can move down even if the engine of the
loader is turned off. Safe stopping procedure:
Lower the boom and the attachment on the ground.
Shut down the loader engine and lock the parking brake.
Release residual pressure from the hydraulic system; move all hydraulic control
levers to their extreme positions a couple of times.
Prevent starting of the machine, remove ignition key.
Beware of entanglement and crushing hazards especially when cleaning or removing
blockages. Always stop the attachment by turning the auxiliary hydraulics control lever to
its neutral position before leaving the driver’s seat, shut down the loader engine and
release the residual pressure of the hydraulic system to prevent rotating parts from
moving when clearing a blockage.
Wrong, improper, or careless use of the attachment causes serious risk of severe injuries
or death. Familiarise yourself with the controls of the loader in a safe area. Pay particular
attention to the safe stopping of the attachment and the loader; follow the safe stopping
procedure shown in this manual before leaving the driver's seat.

Make sure that an unlocked attachment will not move or fall over. Do not stay in the
area between the attachment and the loader. Mount the attachment only on level
surface.
Never move or lift an attachment that has not been locked.
Avant quick coupling system:
Step 1:
Lift the quick attach plate locking pins up and turn them backwards into the slot
so that they are locked in the upper position.
If your loader is equipped with a hydraulic attachment locking system, see
additional instructions about the use of the locking system from the relevant
manuals.
Ensure that the hydraulic hoses (and the electric harness, if applicable) are not
in the way during installation.
Step 2:
Turn the quick attach plate hydraulically to an obliquely forward position.
Drive the loader onto the attachment. If your loader is equipped with a
telescopic boom, you can utilise this.
Align the upper pins of the loader’s quick coupling plate so that they are under
the corresponding brackets of the attachment.
Step 3:
Lift the boom slightly – pull the boom control lever backward to raise the
attachment off the ground.
Turn the boom control lever left to turn the bottom section of the quick attach
plate onto the attachment.
Lock the locking pins manually or lock the hydraulic locking.
Always check the locking of pins.
5. Attaching the attachment
Attaching the attachment to the loader is quick and easy, but it must be done carefully. The attachment is
mounted to the loader boom by using the quick attach plate on the loader boom and the counterpart on the
attachment.
If the attachment is not locked to the loader, it may detach from the loader and cause a hazardous situation.
The loader must not be driven and the boom must never be lifted when the attachment has not been locked.
To prevent hazardous situations, always follow the coupling procedure shown below. Also remember the
safety instructions shown in this manual. The attachment is mounted to the loader as follows:
12 (26)
An attachment that has not been completely
locked to the loader may fall on the boom or
towards the operator, or fall under the loader
during driving, causing loss of control of the
loader. Never move or lift an attachment that
has not been locked. Before moving or lifting
the attachment, make sure that the locking
pins are in the lower position and come
through the fasteners on the attachment on
both sides.
Excessive tilting or lifting of an unlocked attachment increases the risk of tipping the
attachment over. Do not use the automatic locking of the locking pins when the
attachment is lifted more than one meter from the ground. If the locking pins do not
return to the normal position when tilting, do not tilt or raise the attachment any
more. Lower the attachment on the ground and secure the locking manually.
Never connect or disconnect quick couplings or other hydraulic components while the
control lever of the auxiliary hydraulics control lever is locked on or if the system is
pressurized. Connecting or disconnecting the hydraulic couplings while the system is
pressurized may lead to unintended movements of the attachment, or ejection of
high-pressure fluid, which can cause serious injuries or burns. Follow safe stopping
procedure before disconnecting hydraulics.
Keep all fittings as clean as possible; use the protective caps on both the attachment and
the loader. Dirt, ice, etc. may make using the fittings significantly more difficult. Never
leave the hoses hanging on the ground; place the couplings onto the holder on the
attachment.
Connecting the multi connector system:
1. Align the pins of the attachment connector with corresponding
holes of the loader connector. The multi connector will not
connect if the attachment connector is upside down.
2. Connect and lock the multi connector by turning the lever towards
the loader.
5.1 Connecting and disconnecting the hydraulic hoses
On the 200 series 2 and 400-700 series loaders the hydraulic hoses are connected using the multi connector
system. If you have an Avant 300-700 series loader with the conventional quick couplers and wish to change
to the multi connector system, contact your Avant dealer or service point for instructions or installation
services.
13 (26)
To disconnect the multi connector system:
Before disconnecting put the attachment down on a solid and even
surface.
1. Switch off the auxiliary hydraulics of the loader.
2. While pushing unlock button, turn the lever to disconnect the
connector.
3. After ending operation put the multi connector on its holder on the
attachment.
Conventional quick couplings
(alternative couplings for some loader models):
Before connecting or disconnecting the standard quick couplings, the
residual pressure must be released as shown below. The conventional
quick couplings will not connect, if there is pressure in the hydraulic
system.
Make sure that all three quick coupling fittings are properly connected, otherwise the
hydraulic motor of the attachment may get damaged.
When uncoupling the attachment, always disconnect the hydraulic couplings before
unlocking the quick attach plate, to prevent hose damage and any oil spills. Reinstall the
protective caps on the fittings to prevent impurities from entering the hydraulic system.
The lever should move easily all the way to its locking position. If the lever does not slide smoothly, check the
alignment and position of the connector and clean the connectors. Also shut down the loader and release the
residual hydraulic pressure.
To connect and disconnect the standard couplings, move the collar at the end of the female fitting. The hoses
should be connected so that the fitting equipped with a coloured cap is connected to the corresponding fitting
of the loader. Note that the protective caps on the loader and the attachment can be fastened to each other
during operation to reduce the accumulation of dirt. When disconnecting the standard quick couplings a small
amount of oil may drip from the couplings. Wear protective gloves and have some cloth at hand to keep the
equipment clean.
Disconnecting hydraulic hoses:
Before disconnecting the fittings, lower the attachment to safe position on solid and level surface. Turn the
control lever of the auxiliary hydraulics to its neutral position.
Releasing residual hydraulic pressure:
In case residual pressure is left in the hydraulic system of the attachment, it is often possible to disconnect the
hydraulic couplings, but it may be difficult to connect them the next time. If the fittings will not connect, the
residual pressure must be released by turning the auxiliary hydraulics control lever of the loader, when the
engine is turned off. To make sure that there will not be residual pressure in the hydraulic system of the
attachment, shut down the loader engine and move the auxiliary hydraulics control lever of the loader back
and forth before disconnecting the couplings.
14 (26)
Always keep a safety distance of at least two metres to
other persons. Note that the attachment may throw
stones, gravel, or other objects found in the area at high
speed. Keep bystanders away.
Avoid overturning of the machine. Do not extend the
telescopic boom, when the load approaches the lifting
capacity of the loader, or when the loader boom is in
horizontal position. If the load indicator of the loader (if
fitted) signals, lower the load calmly and retract the
telescopic boom. Avoid sudden changes in speed or
direction whenever the load is lifted. Use additional
counterweights as needed.
Keep a safe distance from the attachment when it is
irunning and stay back if other person operates the
controls of the loader. Be careful not to reach into a
running attachment by any means. Beware of the
rotating parts which create entanglement hazard. Shut
down the loader engine if reaching into the attachment
is necessary
6. Instructions for use
Check the attachment and the operating environment once more before starting to work, and that all obstacles
have been removed from the operating area. Quick inspection of the equipment and the operating area before
use are parts of ensuring safety and the best performance of the equipment.
15 (26)
.
..
Check that all blades are connected securely and that none of the blades is missing.
Loose, damaged, or missing blades can cause ejection of parts from the mower. Only
use locking nuts for fastening if the blades.
Pay attention that a heavy load or long distance between the loader and the centre of
gravity of the load will affect the balance and handling of the loader. The use of additional
counterweights is recommended especially when operating smaller loader models. For
200-series loader the wheel weights are recommended. With heavy loads, the telescopic
boom must be kept retracted while moving with the loader.
Never allow anyone to get under the raised load or the loader boom. Keep in mind that the
loader boom can be lowered or tilted even if the engine has been shut down (crushing
hazard). The loader is not intended to be left to keep a load elevated for longer periods.
Always lower the attachment to a safe position before leaving the driver's seat.
.
6.1 Checks before use
Check that all obstacles, including any possibly hidden ones, have been removed from the working
area before operation.
Check daily that the blades are intact and can rotate freely. Never use if blades are missing or broken.
Check that there is no string or other foreign material around the flail shaft.
Ensure that bystanders are at a safe distance when operating the equipment. Do not let anyone to
enter danger area of the boom or to stay directly in front of the loader. Also make sure that it is safe to
reverse with the loader. Never assume that bystanders will remain where you last saw them;
especially children are often attracted to the moving equipment.
Check the general condition of the attachment and the loader, and check for possible hydraulic oil
leaks. The attachment must not be used, if there is a fault in the hydraulic system of the loader or the
attachment. Refer to Chapter 7 for maintenance instructions.
Operate the attachment and the controls of the loader only when seated on the driver’s seat. Ensure
that the loader and the attachment are used in a safe manner and as intended. Do not allow children
to operate the equipment.
Never operate the loader or attachments while under the influence of alcohol, drugs, medication that
may impair judgement or cause drowsiness, or if not otherwise medically fit to operate the equipment.
Remember correct working methods and avoid leaving the driver’s seat unnecessarily.
16 (26)
Move the auxiliary hydraulics control
lever of the loader towards its locking
position (or use electric buttons on
joystick, if equipped) to operate the
mower.
Stop by releasing the lever to neutral
position.
The mower is intended to be operated
only to forward driving direction.
The mower will only rotate to intended
running direction. Reverse direction of
the auxiliary hydraulics control has no
effect.
Operate the attachment keeping the hydraulic flow within recommended range. Never
exceed maximum allowed input of hydraulic energy.
Operating the attachment at too high speed may cause material be thrown from the
attachment, or damage that could lead to personal injury. See recommended input flow in
this manual.
Never leave the equipment running unattended. Start the attachment only when it is
ready to be used. Do not go near the equipment when another person operates the
controls of the loader.
.
6.2 Using the flail mower
Before starting the mower:
Set and adjust the mower to correct operating position. See following chapters about floating system and
adjustments.
Starting the mower:
Recommended operating speed and maximum allowed oil flow:
17 (26)
Normal operating position:
Keep top link unlocked
Lower attachment on the ground
Keep the quick coupling plate to near vertical
position
Adjust the boom height so that the mower can
move freely up and down
Lifted position:
When operating the flail mower on tall vegetation or
thick scrub, it may be useful to tilt the front of the
mower up.
To lock the top link:
To lock the front end of the mower up, use the pin
to lock the top link to fully retracted position.
The locking pin is stored on the frame of the
attachment (1).
6.3 Operating position and floating
.
18 (26)
When driving with the loader, keep the flail mower
lifted off the ground and tilted back slightly, as shown
in adjacent figure.
Keep the top link unlocked or locked to extended
position (see page 17 for top link locking).
The cutting height of the flail mower can
be adjusted by changing the settings of
the roller and the skids, highlighted in the
adjacent figure.
Loosen the nuts with a single 24 mm
tool
Do not fully remove the nut -
loosen only enough to move the
bolt so that the height can be
adjusted.
Ensure the stability of the flail mower
during adjustments; use blocks of
wood for example. The mower
should be kept attached to loader for
performing the adjustments.
Set all fasteners to the same level.
.
6.3.1 Transport position
6.4 Adjusting cutting height
6.5 Operating on inclined terrain
Extra caution is needed when using the equipment on inclined terrains and slopes. Drive slowly especially on
inclined, uneven, or slippery surfaces, and avoid sudden changes in speed or direction. Operate the controls
of the loader with careful and smooth movements. Watch out for ditches, holes on the ground, and other
obstacles, as hitting an obstacle may cause the loader to tip over.
Maximum lifting capacity can not be achieved on inclined terrain. On horizontally tilted terrain the load must
not be lifted high. The loader frame articulation should be kept straight when lifting heavy loads; turning the
load during lifting operation will affect the stability of the loader and may lead to overturning of the machine.
19 (26)
Warning - cutting hazard. Clearing a blockage can start the flail unexpectedly immediately
after clearing the blockage, if the auxiliary hydraulics of the loader is left on.
Always stop the loader by following the safe stopping procedure before going near the
mower. Never reach to the cutting deck if the mower or its blades can move.
To prevent accidents, turn the auxiliary hydraulics control lever of the loader to its neutral
position, shut down the loader engine and release the residual pressure always before
going near the attachment.
To make sure that the attachment will not rotate, disconnect the multiconnector (or
hydraulic quick couplings) before going near it.
.
6.6 Preventing and clearing blockages
Keeping the rotating speed sufficiently high and drive speed low on demanding conditions are essential to
avoid blockages. Keep the equipment clean, so that material will not stick on it.
Wet, thick and log grass can get coiled around the flail shaft if drive speed is too high. When mowing high or
wet hay more than one run may be needed for even results. Also, adjusting the cutting height to higher
setting, or operating at lifted operating position, will help avoiding blockages.
If blockage occurs, it needs to be cleared manually using suitable tools. Follow safe stopping procedure
before going near the mower.

blades.
Blades
Note: Always fit the spacers shown in figures above when using Y- or L-flails.
When replacing blades, also the fastening bolt and the locking nut should be replaced ( M14*80 bolt with
nyloc nut).
Use only locking nuts for fastening of the blades
Check if replacement of the spacers of the Y- and L-flail is necessary
21 (26)
Make sure the attachment is properly supported during all maintenance work. Never go
under a lifted attachment. The loader boom may lower unexpectedly during maintenance
causing serious injuries even when the loader engine is not running. All maintenance and
service must be performed when the attachment has been lowered down to a safe
position.
Never handle hydraulic components when the
hydraulic system is pressurised, since a fitting
may break or become loose and the released
oil may cause serious injuries. Do not use the
equipment, if you have discovered a fault in
the hydraulic system.
Regularly clean the loader oil cooler core; refer to the operator's manual of the loader for
more instructions. Overheating oil decreases the power and affects the service life of the
hydraulic components of both the attachment and the loader.
7. Maintenance and Service
The attachment has been designed to be as maintenance free as possible. Continuous maintenance includes
regular cleaning and lubrication, and monitoring the condition of the attachment. Because of the crushing
hazard caused by lowering machine parts, all maintenance work must be done when moving parts have been
lowered down completely and the attachment is lowered flat against the ground.
7.1 Checking hydraulic components
Check the condition of the hydraulic hoses and components when the engine has been turned off and the
pressure has been relieved. Do not use the equipment, if you have discovered a leak in the hydraulic system
of the attachment or the loader. Leaking hydraulic fluid may penetrate skin and cause serious injuries. Seek
medical attention immediately in case hydraulic fluid penetrates the skin. Wash any part of body that has been
in contact with hydraulic oil carefully with water and soap. Hydraulic fluid is also harmful to the environment
and any leak to the environment must be prevented. Repair all leaks immediately after detecting them; a small
leak can quickly grow into a big one. Operate the attachment only with type of hydraulic oil that is accepted for
use in Avant loaders.
Check hoses visually for cracks or abrasions. If there are signs of leaks, to check a component, hold up a
piece of cardboard in the area where a leak is suspected. Do not use hands to search for leaks. Monitor the
wearing of the hoses and stop the use, if the surface layer of any hose has worn off. Check the routing of the
hoses; adjust the hose clamps to avoid abrasion to the hoses. The hoses have limited service life. Depending
on operating conditions all hoses must be inspected thoroughly no later than after 3 to 5 years of use, and if
required, they must be replaced with new ones.
Finding any fault means that the hydraulic hose or component must be replaced and the equipment must not
be used until it is repaired. Spare parts are available from your nearest AVANT retailer or authorised service
point. Leave the repair work to professional service technicians, if you don’t have adequate knowledge and
experience about hydraulic assemblies and how to perform the repairing safely.

There are lubricating points at the roller bearings.
Suitable lubrication interval depends heavily on
operating conditions but lubricant must be added
at least after every 10 hours of use. Adequate
lubrication must be ensured, and if the bearings
are dirty, lubricant must be added; added
lubricant will push out dirt.
Clean the end of the nipple before greasing and
add only a small amount of grease at a time. All
lubrication nipples are standard R1/8" nipples.
Replace any damaged nipples.
The fastening bolts and nuts should be replaced with new ones when replacing blades.
.
7.2 Cleaning the attachment
Clean the attachment regularly to prevent accumulation of dirt which is more difficult to remove. A pressure
washer and mild detergent can be used for cleaning. Do not use strong solvents, and do not spray directly at
the hydraulic components, or at the labels on the attachment.
7.3 Lubrication
7.4 Checking metal structures
Also the metal structures of the attachment must be inspected regularly. Check visually for damages and
inspect the quick attach brackets and their surrounding area carefully. The attachment must not be used if it is
deformed, cracked, or torn.
Welding repairs are only allowed to be carried out by professional welders. When welding, only methods and
additives suited for steel used in bucket must be used. For more information about repairs contact your
nearest service point.
7.5 Blade maintenance
The condition of the cutting blades should be checked at least after every few uses The blades wear down in
normal use and can get damaged if hitting a rock or other obstacle.
If the cutting results have weakened from the original, the cutting blades have probably become blunt or some
of the blades have been damaged. Uneven cutting results, increased power requirement and increased
vibration level are signs of blunt or damaged blades.
To protect the blades and other components when hitting rocks or other obstacles, the blades are fitted to the
axle in a way that allows them to move. Check that all of the blades move freely and are not stuck. The Y- and
L-type blades are sharpened from the both sides and they can be installed the other way round. When
reinstalling the blades, make sure, that you fix them in the same manner as they were originally. Do not over
tighten the blade screws.
23 (26)
Check that all blades are connected securely and that none of the blades is missing.
Loose, damaged, or missing blades can cause ejection of parts from the mower. Only
use locking nuts for fastening if the blades.
If the blades have large notches or cracks or have worn down excessively, they must be
replaced. Always use good protective gloves when handling the blades.
Check that the flail mower is balanced to avoid damage to the bearings. Repair the
mower, if you notice any abnormal vibration or noise. Contact service for assistance.
