2. Designed purpose of use
The AVANT Silage dispenser is an attachment that is suitable for use with AVANT multi purpose loaders that
are shown in Table 1. The attachment is intended for dispensing precision chopped silage and feeding stuffs
made with feed mixers. It is a quick and easy way to distribute silage in cowhouses, poultry farms etc. The
dispenser bucket can be filled like a normal bucket directly from floor level, or from a silo. The bucket
distributes silage to about 10 cows / fill - it takes approx. 10 minutes to distribute silage to 50 cows.
Inside the bucket there is a hydraulically driven conveyor and discharging openings to both right and left side.
Material can be discharged to the left or to the right by turning the auxiliary hydraulics control lever of the
loader in either direction. Adjustable side hatches allow controlled distribution of looser materials like crushed
grain as well. Manual side hatch adjustment is a standard feature, hydraulic side hatch operation is available
as an option. Operating speed is adjustable by controlling the auxiliary hydraulics flow of the loader with the
engine RPM.
The bucket is intended only for soft, loose materials typically used at farms. The Silage dispenser is not
designed for any other use than what is specified in this manual and must not be used for any other purposes
than what is intended for.
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 technicians. 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 dealer if you have additional questions about the operation or maintenance of the equipment, or if you
require spare parts or maintenance services.

The compatibility recommendations are based on the width of the loader, lifting capacity, and adequate
breakout force. Normally the width of the attachment should match roughly the width of the loader. When
using too wide attachment the actual breakout force (bucket tilting capacity) decreases and the overall
performance will decrease.
It is recommended to use the attachment only with loaders marked with •in Table 1. 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.

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.
DANGER
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
WARNING
When attaching an attachment to the loader, ensure that the locking pins of the
loader's quic
k attach plate are in the lower position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.

This attachment 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.
Risk of tipping over - Lower attachment on the ground before filling from a silo.
Added material can tip the loader over.
Sudden movements can cause the loader to tip over - Operate the controls of
the loader in a slow and calm manner.
Be careful when lifting load to high level or
lifting load from high. Avoid sudden changes in speed or d
irection to maintain
balance of the loader especially when handling heavy loads. Drive slowly and
carefully especially on inclined terrain or slippery surfaces.
Risk of crushing - Never go or allow anyone else to go under the loader boom
or attachment. The stability of the loader may change when leaving the driver’s seat,
leading to tipping over of the machine. Always remember that the boom may lower
unexpectedly due to loss of stability, mechanical fault, or if another person operates
the controls of th
e loader, leading to crushing hazard. The loader is not intended to
be left to keep a load elevated for longer periods. Lower the attachment firmly on the
ground before leaving the driver's seat and never allow anyone to be under the boom
or attachment.
When unlocking and removing the bucket off from the loader, ensure that it is
secured against accidental movement. To prevent the attachment from tipping over,
empty it first and lower it on even surface. Ensure the bucket is supported properly
during storage.
Before starting the dispenser bucket, make sure that there are no foreign objects in
the bucket that could be ejected from the attachment or that could damage the
equipment.
Be sure not to tilt the bucket too far up to prevent material from spilling from the
bucket.
Check the conveyor regularly. Read the instructions on maintenance and servicing
and only use original spare parts.

WARNING
Make sure that overhead clearance is sufficient. Hitting an overhead obstacle may
cause the loader to
tip over. Keep a safe distance from electric cables, lamps, or
other electric systems; hitting live parts may cause electric shock.
Fill only with materials that are suitable for use with the distributor bucket. Never fill
with hard or compacted materials.
Using too fine materials may cause spreading of dust. The bucket is not intended for
spreading grain or flour.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.
Observe maximum load indicated in the operator’s manual of the loader. Be
especially careful when the load sensor indicator is activated, if your loader is fitted
with a load sensor system.
Make sure that the surface can bear the total load. Also follow the correct tyre
pressure settings.
Ensure that ventilation is sufficient when operating indoors. Do not operate the loader
in closed spaces regardless of the engine or fuel type. Exhaust gases may
concentrate to hazardous levels.
Never use the attachment to lift or to transport persons or as any kind of work
platform even temporarily.
Make sure to use only an attachment that is in good condition. Check the attachment
thoroughly in regular intervals. Do not modify the attachment in a manner t

DANGER
Risk of crushing -
Going under the loader boom or an
attachment can cause serious injury or death.
Never go
under the loader boom and prevent others from getting near
lifted boom or attachment. 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. Lower the attachment
firmly on the ground to a safe position before leaving the
driver’s seat.
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.
. ..
DANGER
Risk of crushing and severing of limbs- Always sto
p the attachment before going
near it.
Going near a running attachment creates a risk of crushing and severing of
hands or feet because of moving spreader plate and related components. Always follow
safe stopping procedure.
WARNING
Risk of thrown objects and dust -
Use the Silage Dispenser only for its intended
purpose.
Using the attachment for other purposes than handling and dispensing cattle
feeding materials can cause hazardous ejection of material, dust, or damaged machine
parts. Use only to dis
pense materials that are commonly used as feeding materials.
Consult your Avant dealer if necessary.
WARNING
Choking hazard -
Ensure ventilation when using a loader with combustion engine
indoors. Using the loader engine indoors increases, among oth
er things, the carbon
dioxide level of the air, which affects the safety of the operator. Make sure that ventilation
is sufficient and adapt use periods according to operating conditions.
WARNING
Entanglement and severing hazard - Never go near a broom that is running. The
powerful broom can cause serious injuries to anyone too close to it. Always stop the
attachment following the safe stopping procedure before going near the attachment. If
being near a running attachment is absolutely necessary duri
ng specific maintenance or
fault finding operation, never wear loose clothing, long scarves, jewellery, or other items
that might become entangled with rotating parts while operating the attachment. If
needed, wear a hat to prevent long hair from coming in
to contact with the rotating parts.
Before maintenance and service stop the broom following the safe stopping procedure.
