2. TECHNICAL SPECIFICATIONS
2.1. DESCRIPTION OF THE MACHINE
The Maratona MG is used to cultivate soil for
agricultural purposes. It is provided with two
rows of convex and opposed discs, which
guarantee the optimum mixing of the soil
suited for the preparation of the seed-bed.
The elastic suspension of each disc permits
the following:
- Conformation to the unevenness of the soil
-The displacement of the discs, should they
run into stationary obstacles, such as
boulders
Thus each disc is safeguarded against
possible damage.
The rear roller has the purpose of compacting
the soil and of adjusting the working depth of
the discs. The adjustment of the working
depth is achieved by inserting the conic
adjusting pegs into the perforated sections
It is hitched to agricultural tractors complete
with a three point hitch compatible with the
characteristics listed in Chart 2.2 of the
Technical Data.
The main components are:
A. Top link
B. Pins for hitching to the tractor
C. Lower arms
D. 1st. row of discs
E. Rear levelling roller
F. Side plates
G. 2nd. row of discs

2.3. SOUND LEVEL
If the tractor is complete with cab, the sound level will depend on the level of insulation of the cab itself.
If the tractor does not have a cab, or if the windows of the cab are open, the sound level caused by the
operating machine, measured at a distance of 200 mm. from the rear window, exceeds 74dBa. Therefore, we
recommend the use of earmuffs, as prescribed by the safety rules of different countries.
2.4. IDENTIFICATION OF THE REAR ROLLER
Each machine must be equipped with a rear level
ling roller, which has the
task of levelling the soil and, at the same time, of supporting the machine
It is absolutely forbidden to work without this rear roller.

3. SAFETY RULES
3.1. SAFETY USE
•Before performing any start-up, use and maintenance operations on the equipment, read carefully the owner’s Owner’s
Manual.
•The manufacturer disclaims all responsibility for damages to persons, animals or things due to the non-observance of the
safety rules.
•It is absolutely forbidden to use the machine for purposes differing from the ones expressly indicated in this Owner’s
Manual.
•Absolutely avoid to touch in any way the parts in motion.
•The machine and eventually its options for the transport on public roads must be
complete with the necessary signs and adequate protections.
•It is absolutely forbidden to drive or to let the tractor be driven by persons without
the proper driving license, having no experience and/or not in a good state of health.
•Check carefully the adhesive labels on the machine and follow their indications. The stickers pertaining to safety must be
clearly visible: they must always be kept clean and they must be replaced if they become unreadable ( if necessary they can
be obtained from your local dealer).
•While operating with the machine do not allow any person or animal to approach within the range of operation of the
machine.
•While operating with the machine do not allow any person or animal or object to approach within the area where sods and
stones are thrown by the machine.
•It is absolutely forbidden to enter the area between the tractor and the machine in order to operate the external controls of the
hydraulic lifting device.
•Sit always in the driver's seat and get off the tractor only after the power takeoff has been disconnected and the parking
brake has been activated.
•When taking working breaks, disconnect the power takeoff, switch off the engine, lay the machine on the ground and
activate the tractor parking brake.
•For the transport on public roads always use the danger-warning flashing lights.
•Do not work without guards.
•Do not use the machine as a transportation vehicle for persons, animals or things.
•Do not work on grounds or places which may compromise the
stability of the machine.
•Familiarise yourself with the area where you need to work in.
Never operate in an area in which there are obstacles like stones,
sticks or roots. They might damage the machine.
•When circulating on public roads, always use the danger-warning
flashing light.
•When circulating on public roads, observe the rules in force in each country. It is very important to remember that road
holding, braking capacity and direction are influenced by the weight of the machine applied to the lifting device of the tractor.
Moreover, when turning bends consider the effect of the centrifugal force that shifts the machine centre of gravity.

SAFETY RULES - 6
Copyright ©2009 della Alpego srl ® -Tutti i diritti sono riservati. È espressamente vietata la ristampa o l’uso non autorizzato per iscritto da parte di Alpego srl
•Avoid to let the machine turn idle (outside of the soil). While working avoid turning bends with the machine buried in the
ground. The same applies when you drive in reverse gear. Always lift the machine when you change or reverse directions.
•During transportation, or every time it becomes necessary to lift the machine, it is advisable to calibrate the lifting device of
the tractor, so that the machine is not lifted from the ground by more than 35 cm approximately.
•Avoid driving on public roads with the machine soiled with earth, grass or other materials which may cause dirtying of the
road or hindrances to road traffic. Do not lower the machine abruptly to the ground, but rather lower it slowly in order to
allow the discs to gradually penetrate into the soil.
•Unless this operation is performed in the way described, the components of the machine will undergo very strong stresses
which could compromise their integrity.
•During transportation on public roads with the machine raised, put the lever of the hydraulic lift of the tractor in the blocked
position.
•Do not use the machine within buildings, unless they are sufficiently and adequately aerated
3.2. SAFE MAINTENANCE
•Do not allow unauthorized persons to perform maintenance operations or any other kind of intervention on the machine.
•Maintenance and repairing operations must be carried out in a workshop fit for those purposes.
•In case of maintenance of the machine disconnect the hydraulic hoses from the tractor plugs.
•Always use original options and spare parts in order to comply with the requirements of the manufacturer, otherwise, any
guarantee will become void and some failure may occur impairing the safety of the machine.
•Use only oils having the recommended characteristics.
3.3. TRANSPORT ON PUBLIC ROADS
If necessary, the machine can be transported on the roads while hitched to the tractor. The operator must check, compare and
adapt the implement so that it fully complies with the Highway Code in force in the country where it is used.
Bear in mind the following recommendations:
1. Comply with the instructions in this Owner’s Manual when you hitch the machine to the tractor;
2. The machine must remain blocked and raised from the ground during transport.
3. You must take all possible precautions and comply with the pertinent laws in order to safeguard yourselves and
others.
4. Projecting parts and those wider than the width of the tractor must be fitted with the appropriate protections.
5. The entire implement must be equipped with its own lighting system complete with flashing lights and warning
signals.
6. Warning boards to indicate the projecting parts of the implement must be affixed wherever necessary.
7. The braking distance and steering capacity of the tractor are influenced by the weight of the machine hitched to it.
When driving around bends, take great care and allow for the action of the centrifugal force that shifts the machine’s
center of gravity.

performed by personnel trained in this kind of activity.
Hook the machine as shown in the picture and transport it: during this operation
the machine is not to be lifted from the ground by more than 200 ,,.
If the machine has been supplied with the unassembled rear levelling roller,
it is necessary to assemble it.
Pay the utmost attention, because the machine without the rear roler is not stable.
While keeping the machine off the ground with appropriate lifting means, connect it
with the three-point hitch of the tractor and secure it with the proper safety bolts.
Check that everything is perfectly connected and lower the machine to the ground
Operating with extreme caution.
Attach the roller to the machine as represented in the picture and keep it stable
with the help of adequate lifting means but without lifting it off the ground. Then
proceed as described in Paragraph 3.8
3.8. ASSEMBLY OF THE REAR ROLLER
After you have performer the operations descrive under point 3.7, proceed as
follows:
Assemble the C clamps on the square pipe of the roller frame: at this point the
roller is ready to be attached to the machine. Lift and position it behind the
machine which has previously been hitched to the tractor.
Fasten the 2 upper metal bars A(2 for each perforated section) with bolts in hole
N; position the wedges Dunder the bar of the roller and rest the slanted flat
surface against the end-of-stroke screw Gof the perforated sections. Finally

3.9. HITCHING THE MACHINE TO THE TRACTOR
Check with special attention the weight on the axles and, whenever
necessary, ballast the front of the tractor; check the weight of your
machine in the Chart of Technical Data 2.3). Before you hitch or unhitch
the machine from the three-poin-linkage of the tractor, set the control lever
of the lifting device into ist blocked position.
After you have made sure that the tractor is compatible with the machine you
are going to hitch to it, place the machine on a flat surface, approach with the
tractor at a distance of about one meter. Turn off the engine, activate the hand-
brake, then get off the tractor and get ready to perform the hitching tot he three-
point-linkage.
3.10. CONNECTING TO THE THREE-POINT-LINKAGE
Perform the connection of the lower arms as shown in the picture:
a) Remove the screws A and the nuts B (or the fastening pins)
b) Remove the pegs C
c) Insert the hitching balls into the lower hitching latches D
d) Insert the pegs C, the screws A and the nuts B (or the fastening pins),
choose the most suitable hole depending on the tractor’s lifting capacity
e) Follow the same procedure to connect the upper arm in the holes E
3.11. POSITIONING OF 2ND. AND 3RD. CAT. LINKAGES
Depending on the hitching category of the tractor, the hitching pegs
of the Maratona MG disc harrow must be inserted as shown in the
picture

3.12. CHECKING THE LIFTING ABILITY AND THE STABILITY OF THE TRACTOR
Quando un attrezzo viene accoppiato al trattore, divenendo ai fini della circolazione stradale parte
integrante dello stesso, può alterarne la stabilità e causare difficoltà nella guida e nel lavoro.
L’applicazione di una macchina al trattore, comporta una diversa distribuzione dei pesi sugli assi. A seconda
della composizione della macchina è consigliabile pertanto aggiungere apposite zavorre nella parte anteriore
del trattore in modo da ripartire adeguatamente il peso sugli assi.
When an implement is hitched to a tractor, it becomes an integral part thereof as far as road circulation is concerned.
This implement may alter the stability of the tractor and cause some driving and working difficulty.
The hitching of an implement to a tractor involves a different distribution of the weights on its axles.
Depending on the composition of the machine, it is, therefore, advisable to add ballast to the front-end of the tractor so
as to adequately distribute the weight on the axles

Where:
1) Must be measured.
2) Check the tractor operation and maintenance Owner’s Manual.
3) Must be calculated.
4) Check the operation and maintenance Owner’s Manual of the required implement.
Use the following formula to calculate how much ballast is needed
Gv min. = (Mb tot x (C + Lb tot)) – (Tv x B) + (0,2 x Te x B)
-----------------------------------------------------------------
A+B
The distance from the center of gravity of the combined machine to the lower arms of the linkage of the tractor is calculated with
the following formula
Lb tot = (Lb1 x Mb1) + (Lb2 x Mb2) + (Lb3 x Mb3) + (Lb4 x Mb4) + (Lb….x Mb….)
------------------------------------------------------------------------------------------------------
Mb1+Mb2+Mb3+Mb4+Mb….
- The overall mass of the entire combined machine is calculated with the following formula
Mb tot = Mb1+Mb2+Mb3+Mb4+Mb…..
At any rate, at least 20% of the
combined weight of tractor + hitched implement
must rest on the front carriage of the tractor for
it to be suited to move safely. Always keep in
mind that, besides the correct combination of
tractor and implement, adding ballast to the front
of the tractor, within the limits and following the
directions given by the manufacturer of the
tractor, can improve its stability. Moreover, when
the tractor is stationary, the hitched implement
must be lowered to the ground. This will prevent
any possible accidental drops, while improving
the tractor stability.

4. USE
Follow all the safety rules described in Chapter 3 of this Owner’s Manual and carefully read all documents pertaining to the use of
the tractor. Always make sure that the implement is in perfect working order, that the lubricants are at the correct level (see
Chapter 6.4) and that all parts subject to wear and tear (discs) are perfectly efficient.
The implement must work horizontally: Adjust the upper arm A of the 3-point
linkage so that the B line is parallel to the ground. While working keep side
swings to a minimum by correctly adjusting the stabilizers of the tractor’s
lifting unit.
Operate with estreme caution the first time you use the machine.
Operate the controls of the tractor’s lifting unit to make sure that the impact
with the ground occurs gradually.
While the implement is working the lifting unit of the tractor must be in its
floating position, so that the weight of the implement is resting largely on the
rear roller, which has also the task of levelling the soil.
Whenever driving in reverse gear or changing driving directions always keep
the implement clear of the ground.
4.1. ADJUSTING THE WORKING DEPTH THROUGH THE REAR ROLLER
The adjustment of the implement working depth P is determined
by the position of the rear roller in relation with the lower edge of
the discs.
The greater the difference in level P between the lower edge of
the discs and the lower part of the rear roller, the greater the
working depth.
In practice, an increase in the working depth is obtained by
moving the pegs A into a higher hole and by pushing the wedge
B under the end-of-stroke screw.
In order to descrease the working depth, move the pegs into a
lower hole and lower the position of the peg under the end-of-
stroke screw.
We recommend that you always begin working at a minimum
working depth and then gradually increase it until you have
reached your desired depth. When workign always make sure
that all the pegs and the wedges are in the same positions.
The recommended working depth is 80 mm.

4.2. ADJUSTING THE SIDE PLATES
Depending on the amount of soil moved by the lateral discs in the front row, it is possible to adjust the side plates so that they
better contain the clods within the working width of the implement, so that they can better be discharged behind the rear
compacting roller.
2 types of adjustment are possible:
- The height of the side plates, which depends on the working depth: the greater the working depth, the higher the
position of the side plates
- Lateral adjustment of the side plates depending on the amount of soil lifted by the adjustable outer discs: the greater
the working depth, the further will the side plates be pushed outwards.
The height of the side plate A is adjusted by properly positioning the side plate itself on the square pipe to which it is
attached.
The lateral adjustment of side plate Ais achieved by adjusting its position on the square pipe Bin relation to the frame of the
implement: in practice peg Cis uplifted and both square pipe and side plate are slid outwards until the desired position has been
reached. Make sure that the peg is then correctly inserted into the proper holes in the square pipe.
During transport the side plates MUST be brought back into their innermost position.

5. USE
5.1. ADJUSTABLE DISCS
The Maratona MG disc harrow i s provided with some discs which are adjustable in
height and arranged in both disc rows (front and rear rows). They are positioned behind
the wheels of the tractor.
These discs must work within the tracks left by the tractor tyres: the deeper the track left
by the tyre, the lower will the discs have to be set and, depending on the width of the
tractor tyres, it must be decided how many discs to set lower.
This operation must be performed each time you begin work in a new field and it must
be repeated if the conditions of the soil change, so as to always obtain the best possible
finish of the seed bed.
Fort he adjustment of the discs it is necessary to perfom the following operations.
Remove the screws B from the fixed support.
Slide the arm A upwards until ist holes coincide with the
holes of the support: keep in mind that a single position is
possible for each pitch between two holes.
Once you have decided which position is correct for you,
tighten the bolts B.
5.2. UNHITCHING THE IMPLEMENT
.To unhitch the implement proceed as follows:
•-lower the supportino stands
•-lower the implement to the ground, turn off the engine and pull the hand brake
•-unhitch the connecting point by performing in reverse order the operations described in the paragraph: Connection with the
three-point-linkage
5.3. STORAGE
When the machine remains idle over a long period of time, it is necessary to perform the following operations, in order to keep all
of its organs in good working order:
A. Thoroughly wash the machine being careful to eliminate any trace of fertilizers or chemical products. Dry it..
B. Do not wash the electric components
C. Make sure that the entire machine is in perfect order.
It will be to your advantage when you find it ready for use the next time you need it.
D. Protect all unpainted metal parts with lubricant, then cover it or store it in a dry place.

6. MAINTENANCE
6.1. INSPECTIONS AND CHECK-UPS
During the first 8 hours of work it is advisable to check that all the bolts are still tight, since the stress generated while the machine
is operating will cause a setting of its structure; if necessary tighten them according to the chart. Repeat this check-up every 50
hours of work. Every day check the discs and their bolts.
