2. Designed purpose of use
The AVANT Cutter bar mower is an attachment suitable for use with AVANT multi purpose loaders shown in
Table 1. The mower is a very effective attachment for cutting hay from fields, meadows and road shoulders. It
makes cutting and easy collecting of even long hay possible, while it allows to easily collect the cut hay. The
attachment can also be used vertically for hedge cutting. The mower is attached on the quick coupling plate of
the loader boom, giving excellent visibility to the blade bar that is on the right side of the attachment. The side
reach and blade tilting make it possible to mow also from slopes. The blade guides on the blade bar support
and protect the replaceable special steel blades.
Before each use the blade is adjusted to working position with a manual winch or with the optional electric
actuator system. When transporting the mower, the blade is set to its upper position. The attachment is
started and operated from the driver’s seat driving forward at calm speed that is adjusted according to
operating and terrain conditions. The electric actuator of blade position control can be controlled either with
the optional attachment control switch pack of the loader or with a separate cable kit that is supplied with the
attachment.
The spring release mechanism of the blade bar allows the blade bar to move back when hitting an obstacle.
However, you must stay alert and observe the terrain conditions and the operation of the machine in order to
avoid hitting obstacles. The dangers related to the strong and powerful cutting must always be kept in mind
when operating or otherwise handling the attachment. The attachment is intended for operators who have
learned the safe operation of the loader and the attachment, and are able to notice the risks arising from using
the equipment and terrain conditions. The attachment is not intended to be used by children. The mower can
cut small trees of about maximum around 20 mm in diameter, but the mower is not intended for clearing areas
from growing trees. After the spring release mechanism has freed the blade bar, the loader and attachment
must be stopped safely, and the blade must be turned back to its operating position. Using the attachment in
other ways than cutting hay or mild shrub while controlling the equipment from the driver’s seat of the loader is
prohibited.

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.
WARNING: 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.
Read all safety instructions carefully before handling the attachment
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 Cutter bar 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.
The mower is intended to be used by one adult operator at a time. Prevent others
from entering the work area or getting near the loader when in use. Pay attention to
the surroundings and other persons and machines moving in the vicinity. Always
make sure that it is safe to move with the machine, always keep a minimum safety
distance of at least two metres from other persons.
Never leave the driver’s seat when the mower is running or if the auxiliary hydraulics
control lever is locked on. The blades 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.
Do not drive at high speed unless you can be sure that there are no obstacles at the
working area. The loader may stop suddenly if it hits an obstacle, regardless of the
spring release mechanism. Remember that there may be hidden rocks, pole wires, or
obstructions or fragile surfaces.
Lower the attachment firmly on the ground before leaving the driver’s seat. Make
sure that the attachment is properly supported during any maintenance or
inspections. Do not leave the driver’s seat when the loader boom is lifted. Going
under a raised attachment or loader boom is dangerous, as the boom may lower due
to loss of stability, mechanical fault or when other person operates the controls of the
loader.
Always keep in mind that regardless to the compact size of the attachment, it is very
strong, and can easily sever fingers, arms, or legs, even if the operating speed is set
to low. Follow the safe stopping procedure so that any residual pressure left in the
hydraulic system will not cause unexpected moving of the blades. Put the blade
cover in place whenever the mower is not in use.
Keep the blade bar supported against the upper spring holder to prevent swinging
and sudden movements of the bar, and to prevent hitting obstacles.

8 (28)
Survey the operating area before starting the mower. Observe and mark, as
necessary, any obstructions at the area, such as rocks, posts, or stay wires. Keep the
limits of the machine in mind and remove obstacles or larger trees beforehand.
Lower the blade bar using controlled motion, holding the winch handle while lowering.
Operate the controls of the loader with calm and deliberate movements, avoiding
unnecessary swinging of the attachment. Use the mower only when the blade bar is
set to its normal perpendicular operating position, so that the spring release
mechanism will hold the blade in its proper position, and allows the blade bar to
swing back if necessary.
Operate the controls of the loader only when sitting on the driver’s seat. Wrong
control movements create crushing and severing hazards to any person in the vicinity
of the loader.
Operate only at well lit areas. Make sure that all lights of the loader are in good
condition, clean, and adjusted correctly. Extra work lights are recommended for the
loader when operating during dark. Mark any obstacle at the work area before
operating to avoid collisions.
Shut down the loader engine and release any residual pressure before adjustments
or maintenance work.
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.
DANGER
Stuck blade can move and cut when removed blockage - Risk of cutting and
severing. Never perform any cleaning, maintenance, service, or adjustment tasks if the
loader engine is running or if the auxiliary hydraulics is locked on. Blade bar that has
become stuck may move unexpectedly when removing a blockage because of residual
pressure left in the hydraulic systems may cause cutting motion, creating severing
hazard to any person near the blade bar. Follow the safe stopping procedure shown
below.

9 (28)
WARNING
Risk of crushing - Never allow anyone to get under a lifted attachment or 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.
Cutting with the mower may cause debris to get thrown towards you. Wear
safety glasses.
Wear safety glasses when handling hydraulic components.
.
..
Safe stopping of the attachment, before going near the attachment:
WARNING
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.

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:
WARNING: Crushing risk - 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.
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 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 both locking pins.

14 (28)
Risk of falling objects - Prevent dropping of
attachment
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.
WARNING: Risk of crushing - Avoid tipping over the attachment.
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.
On Avant 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.
WARNING
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.

15 (28)
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 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.
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.
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.
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.

16 (28)
.
5.1 Electric connection
The mower can be equipped with an electric actuator, that replaces the manual winch for lowering the blade
bar.
To operate the electric selection valve on the Cutter bar mower, the electric harness must be connected to the
loader.
There are two options for the electric connection:
1.
The cable harness A35358, delivered with the attachment and
equipped with a 3-position switch, is connected to the 12 V outlet
near the driver's seat on the loader.
Keep the switch in the cab so that it is easily accessible, but will not
be used inadvertently.
2.
Alternatively, the electric function can be controlled with the
attachment control switch pack, which is optional equipment for the
loader. In this case, the separate cable with the switch is not
needed, and the plug of the attachment can be connected directly
to the socket on the loader boom.
Electric socket is integrated in the multi connector on all
loaders equipped with attachment control switch pack from
January 1st 2016.
On loaders manufactured 2015 or before, there is a separate
socket next to the multi connector.
The electric feature on the Cutter bar mower is controlled with the
switch number 2. Other switches are not in use with this
attachment.
Route the selected cable in a way that it cannot get stuck or pinched, or stretch when the equipment moves.
With the help of the attachment control switch pack available for the loader, the attachment control switches
are easily accessible at the end of the boom control lever. Instructions about the power outlet of the loader
can be found in the operator’s manual of the loader.
5.2 Uncoupling the attachment and storage
Uncouple and store the attachment on level ground, but avoid leaving the attachment laying directly on
against the ground. Place it on blocks of wood or on a pallet, for example. The best way to store the
attachment is a place where it is protected from direct sunlight, rain, and extreme temperatures. Make sure
that the attachment is secured against all movements during storage, and never climb on the attachment.
Avoid storing the attachment directly on the ground for long periods of time to
avoid damage from corrosion. Clean and service the attachment before long
storage periods as shown in chapter 7.

17 (28)
.
Correct storage position:
At the front of the mower, there is a support stand, which must be extended to prevent the mower from tipping
forward.
Uncoupling the mower:
1. Select a level and firm storage area that can support the
mower standing upright.
2. Stop the attachment following the safe stopping
procedure. Uncouple hydraulic fittings and electric
harness.
3. Fit blade cover.
4. Turn the blade bar up against the retainer spring.
5. Extend and lock the support stand shown in adjacent
figure.
6. Lower the attachment completely down in upright position
and unlock locking pins. Tilt the quick coupling plate
carefully and manoeuvre the loader away.
A loader that is not equipped with a telescopic boom:
If the loader is not equipped with a telescopic boom, and the mower is stored directly against the ground, the
loader may not reach the brackets of the mower’s quick coupling plate. In this case, a separate lift can be
used, or the mower can be tilted slightly manually holding from its blade bar, so that the quick coupling
brackets will set above the loader’s coupling plate. Before handling the mower manually, drive the loader as
close to the quick attach plate of the mower as possible, and tilt the attachment plate of the loader forward to
minimise the needed manual tilting.
Blade cover:
The blade cover protects both the attachment
and any person near the attachment. Always fit
the blade cover after use and do not remove until
work can be started.
Clean the blade before storage. Allow the blade
to dry before fitting the cover, if storing for longer
periods of time.

18 (28)
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.
Too high operating speed can damage the attachment. Never operate the attachment
with 2-pump setting of loader. See instructions about correct operating speed in this
manual.
Practise the use of the attachment and its controls in an open and safe area. If you are unfamiliar with the
loader in use, it is recommended to practise its use without any attachments.
WARNING
Beware of the sharp and strong blade
bar. Make sure the blades will not move
before going near the attachment.
Start the mower only after it has been
set to working position and work can be
started.
Always stop the attachment before
leaving the driver’s seat and keep a
safe distance to others.
Follow safe stopping procedure always
when it is necessary to go near the
blades or when handling the blade bar,
i.e. cleaning, height adjustment, or
uncoupling the attachment.
Always fit the blade cover when the
attachment is not in use
WARNING
Collision risk - Check the operating area before using the equipment. Running into
an obstacle may stop the machine suddenly and unexpectedly causing injuries from
impact to head and body, regardless of the blade spring release system or other safety
systems.
Drive slowly and pay attention to operating area at all times.
Make sure that there are no hidden obstacles that could cause a collision or
equipment damage.
Mark visibly any potential obstructions beforehand as far as practical so that
collisions can be avoided.
Operate equipment only at well lit areas or make sure the loader is equipped with
sufficient lights.
The spring loaded blade improves safety only when driving forward - when
reversing, drive extremely slow.
Always wear seat belt.

19 (28)
WARNING
Risk of collisions - Ensure good visibility. Never lift this attachment to a height where
visibility is obstructed. Ensure unobstructed visibility to all directions. Keep all windows
clean and free of dirt, ice, snow etc.
6.1 Checks before use
Check that all obstacles, including any possibly hidden ones, have been removed from the working
area or marked visibly before operation.
Make sure that the blade and its spring release system is in full working condition and unblocked
before starting work. All springs must be fastened securely and the blade must be able to tilt back.
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.
6.2 Operating the mower
Working position and reach of blade bar:
Set the blade to a work position before
starting the blade. The adjacent figure shows
the reach of the blade in different positions.
In near vertical positions the blade will lean
against a spring stopper. This keeps the blade
stable in transport position, preventing
swinging of the blade.
The blade bar should be set to near the
surface of the ground, but not completely
leaning on the ground. The lifting cable must
be connected and tensioned when mower is
in use.

Turning the blade bar to operating position:
Before handling the manual winch, stop the attachment following safe stopping procedure. Lower the
blade bar with controlled motion, holding the winch handle throughout lowering.
When using the electric blade bar lowering, the actuator is controlled with switch number 2 of the
attachment control switch pack, or by using the 2-way switch delivered with the attachment.
Starting the mower:
The mower is started by turning the auxiliary hydraulics control lever of the loader to its locking position.
Correct running speed of the loader engine depends on operating conditions and driving speed. The mower
can cut also when it runs slowly, but for the best results, the loader should generate hydraulic oil flow of about
20-30 l/min. On most loaders this is achieved when the loader engine is run at about half of the maximum
rpm, using one hydraulic pump. If needed, check the hydraulic oil output of the loader from the operator’s
manual of the loader.
During operation:
Operating on inclined terrain and slopes requires extra caution. Watch for holes, bumps, rocks and other
possible obstacles, that may be poorly visible. Uneven terrain may tip over the loader. Use low speed on
slopes and do not make sudden changes in speed or direction. Try to drive straight up or down a hill, not
across, to avoid excessive side tilting. If the loader stops while driving up a steep slope, first stop the
attachment and then reverse a little. Keep the articulation of the loader frame in as straight position as
possible. Be careful when operating near ditches or embankments as the machine could slide or turn over if
an edge caves in. Do not lift the attachment high on inclined terrain.
6.3 Blade spring release system
To protect the attachment and the operator the blade bar will swing back if the blade bar hits an obstacle. The
system will not protect the mower or it’s blades against overload, and the attachment may get damaged
regardless of the release system.
The spring release system should work so
that it will allow the blade bar to tilt back
when moderate force is applied to the tip of
the blade bar.
When the spring release system allows the
blade bar to tilt back, stop the loader
immediately and stop also the attachment.
The blade bar can be turned back to
operating position by operating the loader
boom, or by turning it back manually.
Remember to follow safe stopping
procedure before going near the blades.
