CONNECTIONS

Hydraulic

(Machines not equipped with an auxiliary unit)
The machine requires a double-acting hydraulic distributor with an independent lift function. The

machine’s hydraulic circuit operates at a maximum pressure of 180 bar.
The pressure hose is equipped with a female push-pull coupler (ISO 7241).

The return hose is equipped with a female push-pull coupler (ISO 7241).
Connect the distributor supply hoses to the tractor. The pressure hose (P) is identified by a white

arrow on a red background, with the arrow pointing away from the tractor towards the distributor. The
return hose (T) is identified by a white arrow on a blue background, with the arrow pointing away from
the distributor towards the tractor.

35

The hydraulic connection to the tractor may be made in one of three ways:

1. Single-acting distributor pressure and direct return to tank.

2. Double-acting distributor pressure and return to second orifice of the same distributor (beware
of direction of oil flow)

3. Pressure on line to be followed from tractor distributor and return to tank.

Connect the hoses. Make sure that the hoses cannot catch while in operation.
If the machine distributor is connected to the original tractor distributor , activate the relevant handle on

the tractor distributor to pressurise the hydraulic circuit (beware of direction of oil flow).

LIGHTING

Keep all lighting clean and in good working order. Rep air them immediately.
Before taking out onto public roads, check that all lighting is in good working
order.

Plug the lighting equipment into the standardised 7-pin socket at the rear of the tractor .

CONTROL HARNESS SUPPLY

- Machine with remote control cables.

- The electric power cable (2) is not supplied mounted.

- Connect this cable to the + and - terminals on your tractor battery

1

2

If you use a second tractor, ask for a second power cable (2) – part n° A7040064.
For a constant, even power supply to the machine, the electric power cable must be connected to the

battery. The power cable socket (2) is best fitted onto the lower crossbar in the rear opening of the
cab.

4

(brown wire to + and blue wire to -).

- Then connect the socket (1) to the power cable (2) to activate
the controls. The power cable is equipped with a 15 Amp fuse
(4) – part n° A7040915.

When mounting the power cable on the tractor, pay attention to the routing of the wire. Beware of
shearing, burning on the exhaust pipe, etc.

36

ADJUSTING THE DELIVERY CHUTE

- The MINOTOR delivery chute can now be set to two positions:

1. A wide opening for the distribution of fibrous products
(long hay , round bales of haylage, etc.) (photo 1).

2. A narrow opening for the distribution of fine-cut
products and straw blowing (photo 2).

1

The chute opening can therefore be selected according
to the products to be distributed. This is done using the
elbowed connecting rod when the chute is slightly open.

PRELIMINARY CHECKS

. Hydraulic and electrical connections. Make sure that the pressure and return hoses are

properly connected
. Machine securely hitched to tractor
. No loose components
. Hydraulic hoses

. Oil tank level and condition of oil filter (on optional auxiliary unit).

37

NO-LOAD TESTS

Do not stand in the working area of the machine.
Before starting up, the user must familiarise himself with the machine’s

operating controls and their respective functions. Once work has begun, it
will be too late.

Before starting up the machine, check around the machine (beware of
children!). Make sure that you have sufficient visibility .

Keep people and animals away from the danger area of the machine.
In the case of a “free wheel” PTO shaft, the turbine may continue to run for
around two minutes after the PTO has come to a complete standstill.

- Test each control in both directions: arm, grab, beater bars, turbine, chute, axle and cover.

- Check the hydraulic circuit for leaks.

- Test the lighting and signalling system (side lights, brake light s and turn-signal indicators).

UNHITCHING

- Before unhitching the machine, bring the grab inside the body and lower the arm completely (ram
rods fully retracted).

- Lay the machine on the ground so that it is stable (adjust the parking stand if necessary).

- Before unhitching the machine, switch off the tractor engine and remove the key from the ignition.

- Uncouple the hydraulic pressure and return hoses and the electrical connections.

- Apply the machine’s parking brake.

- Remove the hitch safety cable.

- Unhitch the machine.

38

MACHINE OPERATION

Read carefully before starting up the machine.
The machine must be used by one person only.
Before starting up the machine and beginning work, check around the machine

(beware of children!). Make sure that you have sufficient visibility.
Keep people away from the danger area of the machine.

Beware! When operating the loading components (arm, grab, machine body)
and mixing components (cover), make sure that there can be no accidental
contact with a power line.

Never stand behind the machine during product mixing.
Never stand beside the distribution chute while the machine is in operation.
Before starting up, check that the machine is in good condition, the tension of

the chains is correct, the components are properly greased and the screws
are tight.

Before commencing any manoeuvres in reverse gear or operating the loading
gear, sound the horn twice.

1. SILAGE LOADING

Approaching the Silo (Fig. 1 showing an ALTOR 7560)

- Hitch the machine to the tractor (see “Starting Up” section).

- Raise the arm and grab for good visibility .

- Lower the machine as closely as possible to the ground in order to secure it to the silo with its heel

plate.

- Reverse the machine into the silo. Do not try to back your way into the silo by force.

- In the case of a clamp silo, position the machine slightly aslant in order to load as closely as possible

to the wall.

39

Loading (Fig. 2 showing an ALTOR 7560)

1. Lower the machine. It should rest on its ground plate at the front and on its shoe at the rear.

2. Start up the hydraulic circuit on the tractor and bring up to nominal speed.

3. From the cab or platform, position the grab so as to take around 50 cm of product. Make sure that

the cutting angle of the grab is correct. Never attempt to cut into the silo with the grab flat.

4. Always begin cutting the silo from the top, never from the bottom (risk of collapse).

5. Swing the grab gently back and forth while lowering the arm slowly. This will bring the grab down

evenly without upsetting the silo.

6. Once the grab is lowered, bring it back inside the machine body to fill it properly. Raise the arm

with the grab closed and repeat operations 3, 4, 5 and 6 until the machine body is full. Do not
overpack the product.

The kinematics of the arm/grab assembly provides a vertical cutting face and good pick-up from the
floor of the silo.
When loading is complete, bring the grab into the rear door position without overpacking the product.

2. LOADING BALES

Approaching the Bale

- Hitch the machine to the tractor (see “Starting Up”

section).

- Raise the arm and grab for good visibility.

- Remove the twine before loading the bale.

The operator must be standing outside the machine
with the engine off.

- Back the machine up to the bale and position the

machine heel plate as close as possible to the
ground (Fig. 3).

- Position the bale in the direction that it will be unrolled.

- More even distribution and straw blowing is obtained

in this way (Fig. 4).

Loading the bale

- Envelop the bale by fully extending the grab and

bringing down the arm until it comes into contact
with the bale.

- Maintain pressure on the arm while backing up slowly .

- When the bale has entered the machine body,

complete loading by combining grab and arm
movements (Fig. 4).

- For even straw spreading, the bale must remain in

contact with the beater bar .

FIG. 3

FIG. 4

40

3. TRANSPORT

It is strictly prohibited to use the machine to carry persons or animals whilst in
operation or transit.
Observe the maximum vehicle gauge for transport on public roads.

Before entering public roads, make sure that all guards and signalling devices
required by law are fitted and working properly .
Before entering public roads, put the machine into the transport position in
accordance with the manufacturer’s instructions (see Technical
Specifications).

You should always adapt your speed and driving to the track, road or land.
Avoid sudden changes of direction in all circumstances.

Steering accuracy, tractor adhesion, roadholding and effective braking are
affected by factors such as the weight of the towed machine, ballasting of the
front axles and state of the land or road.

Disengage the PTO and wait until the fan comes to a complete standstill (up
to 2 mins.).

4. DISTRIBUTION

MOUNTED AND SEMI-MOUNTED MINOTOR 3050 / MINOTOR 3060

Before getting down from the tractor or before any operations on the machine,
lay the machine on the ground, switch off the engine, remove the key from the
ignition and wait until all moving parts are at a standstill.

Always start up the PTO before running the conveyor/beater bar and always
stop the conveyor/beater bar before disengaging the PTO. Failure to comply
with this procedure will result in a blockage.

Always start the beater bar with the conveyor speed control set to zero.

- Set the fan speed according to the product to be distributed:

. 270 min-1 for silage
. 540 min-1 for straw

- Adjust the tractor engine speed according to the required distribution distance.

41

Silage distribution

- The turbine should be set to 270 min

-1

.

- Engage the tractor PTO.

- Start up the tractor hydraulics and bring up to nominal speed.

- Position the chute so that the silage is correctly channelled towards the floor or a manger.

- Release the grab slightly to ensure that the product is not packed too tightly .

- Product output is adjusted by:

. the tractor engine speed (which determines the hydraulic output and PTO speed),
. the forward speed of the tractor,
. the forward speed of the conveyor (to adjust, refer to “Description of Controls”).

- To distribute silage, start up the beater bar and conveyor (refer to “Description of Controls”).

- To stop distribution for a moment (posts, various obstacles, etc.), stop the beater bar and conveyor
rotation.

- At regular intervals, bring the silage on to the conveyor by pulling in the grab.

- When distribution is over, bring in the arm and grab completely . Close the delivery chute, disengage
the tractor PTO and switch off the engine.

Should the beater bar jam, switch the beater bar and conveyor into reverse in short bursts to free. It
may occasionally be necessary to hold the switch for a few seconds to shift back the mass of silage
inside the body .

Beware of the direction of rotation of the beater bar and conveyor .
A loaded machine running too long in reverse may be seriously damaged.

Never attempt to clear the product by hand or with a tool (fork, etc.) while the
machine is running.

Never climb on the machine or work inside the body while the machine is
running.

Beware! Blades, conveyors and other parts in contact with the product may
wear out quickly .
Any part which, through wear , is in danger of coming away and getting mixed
up with the feed must be replaced immediately .

42

Straw bedding

-1

- The fan should be set to 540 min

.

- Engage the tractor PTO.

- Start up the tractor hydraulics and bring up to nominal speed.

- Position the chute so that the straw is projected where required.

- For even spreading, the bale must remain in permanent contact with the beater bar without over-

jamming it with the claw. Raise the machine slightly at the rear to prevent the bale from being
projected back by the rotation of the beater bar .

- The product output is adjusted by:

. the tractor engine speed (which determines the hydraulic output and the speed of rotation of

the PTO),
. the forward speed of the tractor,
. the forward speed of the conveyor (to adjust, refer to “Description of Controls”).

- To distribute the product, start up the beater bar and conveyor (refer to “Description of Controls”).

- T o stop distribution instantaneously (posts, various obst acles, etc.), stop the beater bar and conveyor
rotation.

- At regular intervals, bring the bale into contact with the beater bar by pulling in the grab.

In the event of a beater bar blockage, switch the beater bar into reverse in short bursts to free.

Beware of the direction of rotation of the beater bar and conveyor .
A loaded machine running too long in reverse may be seriously damaged.

Never attempt to clear the product by hand or with a tool (fork, etc.) while the
machine is running.

Never climb on the machine or work inside the body while the machine is
running.

Beware! Blades, conveyors and other parts in contact with the product may
wear out quickly .
Any part which, through wear , is in danger of coming away and getting mixed
up with the feed must be replaced immediately.

43

Note: Should the turbine or beater bar become jammed, use the hook mounted inside the housing

on the left-hand side of the machine (see photo below) to pull out the jammed product at
the distribution chute or beater bar , then use a lever to ensure that the turbine can rot ate
freely.

44

BELT-DRIVEN MINOTOR 3060

Always start the PTO before engaging the belt drive and always disengage
the belt drive before stopping the PTO. Failure to comply with this procedure
will result in a blockage.

Always start the beater bar with the conveyor speed set to zero.
Always check that the fan is set to 270 min

-1

for silage and haylage and 540

min-1 for straw.

When distributing haylage, it is preferable for the bale to be loaded in
the direction that it will be unrolled.

- The MINOTOR 3060 is equipped with a limit of travel sensor for the belt clutch ram (see photo 3).
This sensor is located under the large side casing just behind the tension spring. It is tripped when
the clutch ram is fully engaged. At this point, the conveyor can be started up in forward motion.

There are several advantages to this design:

- The conveyor only runs forwards when the belt is
fully engaged

⇒⇒

⇒ no risk of beater bar blockage.

⇒⇒

- The conveyor can run in reverse, however, even if
the sensor has not tripped (the beater bar does not
rotate)

⇒⇒

⇒ the body can be safely emptied out of the

⇒⇒

back.

- The conveyor control switch has a latched position
in forward operation which, together with the limit of
travel sensor, makes it possible to use just the left­hand beater bar lever

3

can therefore be left at any time in the latched position

⇒⇒

⇒ the conveyor control switch

⇒⇒

in order to start up the conveyor at the same time as
the beater bar, as on the Minotor 3050 TR with a
hydraulic beater bar .

- The protective cover is only used at the end of distribution. The cover must not be unfolded, therefore,
when the product to be distributed (grass silage, round bales of hay, haylage or straw) is too
voluminous (a round bale must be able to rotate freely).

- In the course of distribution, the machine body may be raised or lowered to:

- keep round bales up against the beater bar when the product is easy (hay, straw, fine-cut
haylage, etc.);

- facilitate bale rotation with tougher products. An approximate height of 50 cm between the
sill wear plate and the ground is recommended (bales of rough-cut haylage, etc.).
