Hydraulic System
•Before performing maintenance or repairs on the hydraulic system, lower the
implement to the ground, relieve pressure in the system, turn off the engine and
remove the ignition key.
•Clean the hydraulic fittings thoroughly before connection. Ensure that the pres-
sure is relieved in the hydraulic system before connecting the hydraulic hoses
to the tractor’s hydraulic services.
•After making repairs to the hydraulic system, thoroughly bleed air out of the
system.
•Regularly check hydraulic hoses for defects such as cracks, bends, chafing or
leaks.
•Avoid spilling oil on the ground. In case of spills, collect the oil and dispose of it
properly.
•In case skin should come in contact with hydraulic oil or grease or in case cloth-
ing should become stained with oil, remove the stained clothes immediately
and wash the affected skin areas thoroughly. Oil and grease are harmful to the
skin.
•Escaping hydraulic oil under high pressure can penetrate the skin and cause
severe injury. If an accident occurs, see a doctor immediately.
Hitching
•An individual is in danger of being crushed during the hitching process. Never
place yourself or anyone else between the tractor and the MAXIROLL, or be-
tween parts that must be attached or connected.
Maintenance and Repairs
•Before servicing or making adjustments to the machine, securely block or un-
fold the machine, engage the tractor and machine brakes, stop the engine and
remove the keys.
•Tighten all nuts, bolts hydraulic fittings or any other fastened assemblies after a
few hours’ use. Check often to make sure that they remain thoroughly tight-
ened. Inspect all pins, screws and bolts for wear or damage and make sure that
all are securely in place to avoid any possible damage or breakdown of the ma-
chine.
•Dispose of oil, grease and filters according to applicable environmental regula-
tions.

Application
The MAXIROLL is an extra rugged roller with a special construction enabling the easy
attachment of additional tillage equipment.
Fig. 1
The MAXIROLL is a three-section roller in
which the sections move independently
of each other. Hydraulic weight transfer
is standard on all models.
MAXIROLL 2007, 630
The MAXIROLL roller prepares the soil before sowing by breaking up clods, and after
sowing it conditions the soil to promote germination and to press down stones.
MAXIROLL can also be used to break up crusted soil surfaces of both grain and grass
fields.
MAXIROLL can be equipped with optional attachments such as the hydraulic Crack-
erboard. The Crackerboard is primarily used for seedbed preparation. The vibrating
action of the tines breaks up clods, prepares and levels ploughed fields as well as
previously worked fields. If you do not wish to use the Crackerboard, it can be folded
up and the MAXIROLL can be used alone as a roller.

Adjustments and Settings
The MAXIROLL is preset in the factory, but it will always be necessary to make some
fine adjustments before use. Numerous adjustment possibilities make your MAXI-
ROLL more versatile and allow you to obtain optimum performance from the imple-
ment.
Adjusting hitch height
To ensure an even distribution of pressure on the field, the pendulum on the middle
section (Fig. 5) must be flushed with the adjacent fixed frame part. At the same time
the drawbar (Fig. 4) must be accurately aligned with the towing tractor.
An Incorrect towing height results in an uneven packing of the field, as the roller will
not pack the soil evenly on all the sections.
Fig. 3
To obtain optimal towing height, it is
possible to adjust the drawbar end
bracket hitch, so that the height of
the drawbar eye matches that of your
tractor hitch.
With MAXIROLL resting on the jack
stand, loosen bolts (A) and move the
end bracket hitch for accurate align-
ment with the towing tractor..


Adjusting the middle section
Fig. 4
With MAXIROLL in an unfolded position
(see “Operating and Driving Instruc-
tions”), check if the bolts (A) is touch-
ing the tube (B).
This control must be made with the
MAXIROLL attached to the tractor. And
after the drawbar end bracket hitch is
adjusted for the towing tractor.
Fig. 5
The pendulum on the middle section
must at the same time be flush, with
the adjacent fixed frame part.
It is important to locate the MAXIROLL
on level ground in order to set the
middle section correctly.
If the bolts (A, Fig. 6) is not touching the tube and the pendulum is not flushed with
the adjacent fixed frame part, the bolts must be adjusted.
Fig. 6
1. Loosen the locking nut (A).
2. Adjust the bolt (B).
3. Tighten the locking nut (A).
4. Check the pendulum and that the
towing height is correct.
5. The bolt (B) must touch the tube.
Otherwise drive the tractor a little
forward and check the settings.

tion of the wing sections, it is possi-
ble to adjust the backstop (A) for the

Operating and Driving Instructions
Proper operation is essential for optimum performance of your MAXIROLL. Proper
operation concerns both the carrying out of tillage operations in the field as well as
the following of safety precautions. Make sure that you have a thorough under-
standing of all safety precautions.
Unfolding and Folding
Always unfold and fold the wings of the MAXIROLL while the equipment is stationary
and the tractor is parked.

When unfolding and folding with the Crackerboard, make sure that the Crackerboard
is fully raised in the top position, since the tines could collide with each other (see
”Options, Crackerboard”).
Unfolding
Fig. 8
1Lift the wing sections out of the
transport locks (A) using the tilting
cylinder (marked white).
Fig. 9
2Activate the wing fold cylinders
(marked red) and completely unfold
the wing sections.
3Activate the tilting cylinder and
lower the roller onto the ground. Put
the handle for the tilting cylinder in
floating position. (see ”Adjustments
and Settings”).

Before operating the roller, the weight transfer must be adjusted correctly (see ”Ad-
justing hydraulic weight transfer”).
A

MAXIROLL
Side 17
Folding

If the Crackerboard is mounted, it must be fully raised to the top position before
folding (see ”Options, Crackerboard, Operating and driving instructions”).
Fig. 10
1. Activate wing fold cylinders
(marked: red) to the fully extended
position, so that the outermost
ends of the wing sections (A) are
raised.
Fig. 11
2 Activate the tilting cylinder (marked:
white) to the fully extended position
and raise the roller off the ground.
Fig. 12
3. Activate the wing fold cylinders
again and fold the wings up(wing fold
cylinders must be fully retracted).
4. Activate the tilting cylinder and low-
er the roller down into the transport
locks.
Adjusting hydraulic weight transfer
The hydraulic weight transfer system ensures the even distribution of weight
across all sections of the roller.
A
A

MAXIROLL
Side 18
1. With the roller in an unfolded position, relieve the pressure in the wing fold
cylinders (marked: red). Activate the lever for the wing fold cylinders in the
opposite direction.
Fig. 13
2 After a moment, a reading will be
displayed on the manometer. In-
crease the pressure until approx
15 bar.
3Set the cylinders in the floating position. The floating position is necessary
to achieve hydraulic weight transfer, in which the sections are free to move
individually.
4It may be necessary to adjust the hydraulic weight transfer again. It might
also be necessary to operate the machinery at a higher or lower pressure,
depending on soil conditions.
Too much pressure
1The pressure on the outermost rings of the wing sections will be too great.
The rings will be pressed too far down into the soil and they will leave clearly
visible ridges on the outside of the wing sections.
2The middle section will not pack the soil sufficiently, which can be seen
when the soil trailing behind the middle section is higher and it is not as
compressed as that after the wing sections.
Too little pressure
1There is not enough pressure on the outer rings of the wing sections to
press the rings sufficiently for an even field finishing.
2The middle section packs the soil too heavily, which can be seen when the
soil after the middle section is left much more compressed than that
worked by the wing sections.

For the durability of MAXIROLL and for the result in the field, it is very important that
MAXIROLL is set in floating position when working in the field

Incorrect use of MAXIROLL, as not setting the implement in floating position, can in
worse cases course breakdown on the implement as breach on the mainframe.
A

MAXIROLL
Side 19
Travel speed
A working speed between 6-10 km/hour is recommended, but always drive accord-
ing to conditions.
When travel speed is increased, wear on the implement is increased, especially un-
der dry soil conditions. Damage to the discs may also result from driving too fast
under unfavourable conditions.
Power requirements
Power requirements change according to soil type, terrain, travel speed and roller
rings.
