HITCHING
Note: Before hitching the machine to the tractor, make sure that there is sufficient ballast on the front
axle of the tractor.
Ballast should be added to the special supports according to the tractor manufacturer’s instruc-
tions. The front axle load must be not be less than 20% of the unladen tractor weight.
1. HITCHING THE MACHINE FOR USE ON PUBLIC ROADS
- Usingtheparkingstand,setthetowingeyetothe
requiredheight.
- Backupthetractorandlift the parking stand once
the machine is hitched.
- Lock the hitch with the special device.
- Couple the hitch safety cable to a fixed point on
the tractor frame with the snap link.
2. HITCHING THE MACHINE FOR USE ON THE FARM ONLY
- Fit the drawbar (1) onto the lifting arms.
- Lock the drawbar (1) with 10 mm clips (2) (not
supplied).
- Back up the tractor until the towing eye is lined up with the pin hole in the drawbar.
- Insert the pin and fasten it.

3. ADJUSTING THE TOW BAR
- KEEPING THE BODY LEVEL WILL ENSURE A GOOD MIX.
The tow bar supporting plate (Fig. 3, item 1) can be mounted in two positions providing a total of six
possible height settings.
These six settings and adjustments are illustrated in figure 4.
To adjust:
- Remove the tow bar by extracting pin 4.
- Unscrew the four bolts (Fig. 3, items 2 & 3) on each side of the tow bar (24 mm wrench).
- Put the bolts (Fig. 3, items 2 & 3) back into the required holes.
- To change from position A to position B (Fig. 4) or vice-versa, rotate the tow bar supporting
plate (Fig. 3, item 1) through 180°. The two plates will also need to be swapped over, in other
words the right-hand plate will need to be mounted on the left and the left-hand plate on the
right.
- Refit the tow bar.
The various hitch heights according to the position of the tow bar support (Fig. 4, position A or B) and
the hole (Fig. 4, hole 1, 2 or 3) are illustrated in Fig. 5.
N.B. For easier straw blowing, tilt the machine slightly forwards. The bale will then remain in contact
with the beater bars.

Before carrying out any maintenance on the machine, switch off the tractor
engine, take the key out of the ignition, wait until all moving parts are at a
standstill and uncouple the universal drive shaft.
The mixing hopper is an option designed to mix a number of products, such as meal or pellets, in
order to add them to silage.
The mixing auger produces a uniform blend of all ingredients. The injection auger located below the
hopper feeds the turbine. The minerals are mixed with the silage by the turbine.
1 - LOADING
If the machine is equipped with a hydraulic unit, the speed control unit must
be set to neutral.
- Checkthattheinjectionauger knob is set to 0.
- Lift the lid completely.
- Withabucketoracontinuousfeedingsystem,
loadtheingredientsto bemixedintothehopper.
- Close the lid.
Recommendations:- Turn the mixing auger to get more into the hopper.
- Load the hopper from the left-hand side.
- Itispreferabletoputtheconcentratesintothehopperbeforefillingthe
machine with silage. This will enable you to turn the mixing auger
withouttheriskoffillingthe turbine with silage (in the caseofmachines
with a Polydrive and hydraulic unit).
MACHINE OPERATION
RECOMMENDATIONS FOR USE

2 - MIXING
- Set the injection auger knob to 0.
- Switch on the mixing auger.
- Leave running for a few minutes to obtain the most uniform blend possible.
Iftheaugerisleftrunningtoolong,the blend is liable to lose its uniform quality.
3 - FEEDING
- Feeding with a mixing hopper is identical to simple silage distribution (read the section on “Silage
Distribution” in the machine instruction manual).
- While feeding, the mixing auger must be left running to empty the hopper completely.
- Once the conveyor has been set into forward motion, simply turn the knob to adjust the injection
auger to the required speed.
- To stop feeding (posts, various obstacles, etc.), turn the injection auger knob back to 0 then quickly
disengage the beater bar and conveyor (except on ALTOR 4560, see below).
- After feeding, stop the conveyor and beater bar, turn the injection auger knob back to 0 and stop the
mixing auger. Close the delivery chute then disengage the tractor PTO.
The product output rate is adjusted by:
- the variation in the tractor engine speed: control over the hydraulic flow and the PTO speed;
- the tractor ground speed;
- the conveyor and injection auger speed.
Note: On machines equipped with a Polydrive system, when the beater bar is disengaged, the
conveyor and the injection auger are also stopped. Conversely, when the beater bar is
engaged, these two functions start up again.
Recommendations: - On starting the beater bar or bars, silage may come out of the delivery
chute without being mixed with the concentrates in the hopper. This is
due to the load of silage on the beater bar(s).
- Each particular mix has its own specific injection auger speed setting.

18
This is done to find out the weight of product conveyed to the turbine according to the injection auger
speed. This can be done with the aid of the discharge flap on the injection auger tube.
- If this flap is closed, the mix goes directly into the turbine.
- If this flap is open, the mix can be collected and weighed.
What to do:
- Fill the hopper with the ingredients to be mixed.
- Make sure that the blend is uniform.
- Place a container under the flap.
- Open the discharge flap.
- Engage the PTO and bring the tractor engine to the appropriate speed for feeding. Keep this speed
constant.
- Turn the injection auger knob quickly to a precise setting (number 2 for example).
- Record the time required to fill the container.
- Once the container is full, stop the injection and mixing augers, disengage the PTO and switch off
the tractor engine.
- Close the discharge flap.
- Weigh the full container.
You now know the time required to inject a certain weight of the mix into the turbine at a given engine
speed.
Carry out the test again with a higher setting (number 4 for example).
The output rate at the maximum setting is very important!

MAINTENANCE
Before carrying out any maintenance on the machine, switch off the tractor
engine, take the key out of the ignition, wait until all moving parts are at a
standstill and uncouple the universal drive shaft.
1 - GREASING
The greasing points are identified by a label featuring a white grease pump on a blue background.
Some grease nipples are located under guards or protective caps.
We strongly recommend that you take the time when your machine is delivered to open all of the
guards to identify the various greasing points. Remember that regular greasing will increase the life of
rotating parts considerably.
To grease the mixing auger bearings, refer to the machine instruction manual (identical to “Greasing
the beater bar bearing”).
2 - MIXING AUGER DRIVE CHAIN TENSION
- Check every 100 hours.
If the sag exceeds 15 mm, tighten the
chain.
- Loosen the two nuts (1).
- Tighten nut (2) until the chain tension
is correct.
- Tighten the two nuts (1).
- Grease the chain.
Always leave 4 mm of sag.
3 - ADJUSTING THE MIXING AUGER HEIGHT
The mixing auger must pass as close to the bottom of the hopper as possible, without touching it,
in order to leave the minimum amount of product behind.
Please consult your dealer to make this adjustment.

20
4 - STORAGE
If the machine is not to be used for a long period, it must be prepared for storage as follows:
- Clean the hopper (inside, outside and underneath) with a hose. Remove any build-up of product.
Make sure that there is no product left in the injection auger tube.
- When cleaning with a high-pressure jet, take great care with sensitive areas (hydraulic connections,
hoses, bearings, etc.).
- Repaint any areas that are in danger of rusting with a special paint.
- Clean all greasing points and joints. Grease (refer to the chart in the machine instruction manual).
- Grease the mixing auger drive chain.
- Store the machine in a sheltered place and on blocks to protect it from ground damp.
