This symbol appears in the instruction manual each time there is a safety warning
concerning your safety, the safety of others or the safe operation of the machine.
All safety instructions must be observed and made available to all users of the ma-
chine.
General
•Ensure you are familiar with all aspects of the machine before use
•There are safety stickers on the machine containing important instructions for
the safety of yourself and others, and correct use of the machine.
•Do not carry passengers during operation or transport.
•Ensure there are no personnel within the machine's extension radius before
operating the implement. Only operate machine from inside the tractor.
•When the implement is retracted, check that the side sections are locked.
Check all control levers are secured against accidental operation.
•Before leaving the tractor or making adjustments, performing maintenance or
repairs on the implement, extend fully and lower it to the ground, or maintain it
in the transport position. Apply tractor handbrake, switch engine off and re-
move ignition key to secure the machine against accidental operation.

Hydraulics
•Fold out machine and set down on an underlay for any repair work on the hy-
draulic system. Relieve hydraulic pressure, switch engine off and remove igni-
tion key.
•Clean hydraulic connections thoroughly before reconnecting. When connecting
hydraulic hoses to tractor hydraulics, ensure they are not under pressure.
•It can be difficult to completely depressurise hydraulic systems with pilot-
controlled non-return valves. Hold a cloth around the fittings/part to be re-
moved to catch any oil.
•Bleed the hydraulic system thoroughly after any repairs.
•Check hydraulic hoses regularly for defects such as cracks, splits, crimps, wear
or breaks. Defective hoses must be replaced immediately.
•Avoid spilling oil on the ground. If oil is spilt, collect and deliver to a disposal
point.
•Clean hands thoroughly after contact with oil and grease. Change oil-stained
clothing immediately. Hydraulic oil can be harmful to the skin.
•Hydraulic oil released under high pressure can penetrate the skin and cause
severe injury. In the event of injury, seek medical help immediately.
Assembly
•Danger of crushing! Ensure no personnel are between implement and tractor,
or between the parts to be connected.
Maintenance and repair
•Ensure machine is adequately supported or fully extended for all repair and
maintenance work. Ensure tractor and machine are properly braked, engine
stopped and ignition key removed.
•Tighten all screw connections after a few hours use. Check all screw connec-
tions regularly and tighten as required. Check all split pins and bolts to avoid
mechanical failure.
•Dispose of oil, grease and filters in accordance with local environmental pro-
tection rules.

Road transport
•All statutorily required safety and warning features must be fitted and tested
before transporting the machine on public roads. The driver is responsible for
correct lighting and warning signs in accordance with traffic regulations.
•Check with local traffic authorities whether transport on public roads is allowed
given the machine's dimensions.
•When transporting, ensure permitted total weight for tractor is not exceeded
and that loading on tractor front axle is not less than 20% of tractor net weight.
If this is the case, use weights on tractor front.
Correct use
•Correct use of the machine includes observing the manufacturer's operating,
maintenance and repair instructions, and ensuring that original spare parts
are always used.
•The implement may only be used, maintained or repaired by persons who are
familiar with it and who are aware of the risks that may be involved.
•The manufacturer cannot be held liable for injury or damage arising from modi-
fications made to the machine performed without its prior agreement. Neither
can the manufacturer be held liable for injury or damage arising from incorrect
use. Such liability rests solely with the user.

Description of the machine
Construction
The ROLLOMAXIMUM XL is a robust, multifunctional agricultural implement with the following
features:
•The machine consists of 5 different working implements. At the front there is a parallel-
mounted hydraulically adjustable crackerboard, followed by a Ø53/Ø48 cm cross-kill
roller. This in turn is followed by a harrow with four rows of hydraulically adjustable
tines. The maximum harrow depth is adjusted mechanically by a "hydro-clip" on the hy-
draulic lift, but the entire harrow section is hydraulically raised off the ground, for ex-
ample when turning at headlands. The surface is levelled again by a spring-mounted
mechanically adjustable levelling board. Finally the ground is compacted with a row of
Ø50/Ø45 cm cross-kill rings.
•The side sections are fitted with a hydraulic weight transfer system, which is designed
to transfer some of the weight from the machine centre section to the side wings, in or-
der to ensure uniform tilling of the ground across the full width of the machine.
•For optimum protection of the machine's core components, all assemblies are mounted
on spring mechanisms.
ROLLOMAXIMUM XL is designed to receive the following optional extras:
•The machine can be optionally fitted with track looseners for tractor rear wheel widths
of up to 4.5 metres. In addition, the cross-kill rings can be replaced with a Ø50 cm front
roller cage and a Ø45 cm back roller cage.

Connecting and disconnecting
Connecting
ROLLOMAXIMUM may only be coupled
to the tractor's fixed drawbar, where
the towing eye (A) must fit between
the drawbar forks.
The towing pin (C) is inserted and the
support leg is hydraulically raised to
the maximum height off the ground.
(B)
•The towing pin can be secured with a split pin or similar.
•Note that hydraulic hoses and the support leg are mounted so that they
are not damaged by the tractor's lift arms and tyres when the tractor / ma-
chine train is turned.
•ROLLOMAXIMUM XL 930 / 1230 should never be hitched to a tractor with a
dead weight of less than 5 tonnes on the rear axle. This is because the ma-
chine presses down on the tractor drawbar when retracting and extending.
•ROLLOMAXIMUM XL 930 / 1230 may only be hitched to a tractor via a pick-
up hitch as shown in the photo on this page. Never use a ball hitch or the
tractor lift arms. This is because the machine presses down on the tractor
drawbar when retracting and extending.
Hydraulics
ROLLOMAXIMUM XL 930/1230 requires the standard four double-acting and single-
acting hydraulic couplings, whereby the assignment and colour-coding are as de-
scribed in the table on the next page. One of the four double-acting couplings is
connected to an electrical valve block on the machine, which supports a total of
four double-acting functions on the machine. This valve block is electrically con-
trolled from the tractor's cab via a contact box (A) and requires a 12 V supply (B).
When the green lamp (C) lights up, it means that the valve with the corresponding
number is activated on the machine, when the valve connected to the white hoses
is activated in the tractor's cab. Only one function can be actuated at a time.

•Check hydraulic hoses for crimping before coupling.
Disconnection
ROLLOMAXIMUM should be folded up (into the transport position) or folded out into
the working position with the transport wheels lifted off the ground before discon-
nection.
The support leg is adjusted so that the drawbar is free in the drawbar forks both
above and below. Remove towing pin and disconnect hydraulic hoses.
Remember to depressurise hoses before disconnecting them. When the machine is
disconnected in transport position, the machine should remain stationary on the
transport wheels and on the hydraulic support leg. Do not use the centre cross-kill
axle as a support.
ROLLOMAXIMUM may only be disconnected on a level surface.
Setting up

ROLLOMAXIMUM XL
Page 14
ROLLOMAXIMUM is supplied with factory settings, but fine adjustment will always
be required before use. Numerous adjustment options make the machine more
flexible and optimise its use.
To ensure that the ground is uniformly worked, the drawbar must be correctly
aligned to the tractor used.
Adjusting drawbar height
Supported on a level concrete floor or
similar, the machine is folded out to
working position and the transport
wheels (A) raised free. The cracker-
board (B) and harrow section (C) are
also raised, so that the machine is
now only supported by the two com-
paction sections. In this position, the
entire drawbar shaft (D) should be
level. If it is not so, the assembly
should be adjusted by the drawbar
eye (E) and flange plate (F) until the
drawbar shaft is horizontal.
Driving and operation
Correct operation is vital to get the most out of the ROLLOMAXIMUM. This applies to
working in the field and to safety. Always ensure you are fully familiar with all safe-
ty features of the machine.
Extending and retracting
Extending and retracting the machine must always be performed with the tractor
parked, and on a level surface.
Ensure there are no personnel within the machine's working radius when extending
or retracting.

To reduce the height of the ma-
chine's centre of gravity and lower
the transport height to a maximum
of 4 metres, the machine can be
lowered via the wheel frame (A)
(marked: yellow). The machine is
lowered until there is approx. 9 cm
of clearance under the centre
cross-kill axle (B)
To reduce the machine's transport
width to a maximum of 3 metres,
the harrow section is activated (A)
(marked: white valve bock no. 3),
so that they are pulled as far in to
the machine's centre as possible.
The same is done with the ma-
chine's crackerboard (B) (marked:
green)
Always observe the correct sequence when retracting. i.e., the wheel frame
(marked: yellow) is first activated and the machine is lifted off the ground.
The tilt cylinder (marked: white valve block no. 4) is then activated and the
machine is tilted forward until the side frames and the centre frame are in
the upright position. The side frames can then be retracted via the ex-
tend/retract cylinders (marked: red) and are set down on the transport
cradles via the tilt cylinder (marked: white valve block no. 4).
This is very important for the machine's durability and safety that the side
arms remain in the transport cradles, when the machine is transport in the
retracted state.

Adjustment of hydraulic weight transfer system
The hydraulic weight transfer system distributes the weight evenly between all the
machine's sections.
Once the roller is fully extended and the transport wheels are off the ground, the
extend/retract cylinders are depressurised (marked: red), the cylinder control
lever is then moved in the opposite direction.
This is indicated after a
short delay
by a deflection of the
manometer. The pres-
sure is increased to ap-
prox. 15 bar (B). Some
of the weight from the
machine's centre
is thus trans-
ferred to the side sec-
tions.

The control lever connected to the outlet (marked: red) is then set to the float
position. The floating setting is required to achieve hydraulic weight transfer,
allowing the sections to move independently and protecting the machine's
key components. The pressure will remain indicated on the manometer after
float position has been adopted.
The pressure for hydraulic weight transfer may need adjustment. It may also be
necessary to adjust pressure according to soil conditions.
Excess pressure
1Pressure on the side sections will be too great, leaving clear tracks in the
soil after the side sections have passed.
2The centre section will not compact the soil enough, as the soil after the
centre section has passed is higher and not as compacted as that worked
by the side sections.
Insufficient pressure
1The pressure on the extremities of the side sections will be insufficient to
give uniform compaction.
2The mid-sections will compact the soil too much, leaving the soil after the
mid-section has passed more compacted than that worked by the side sec-
tions.


To prolong the ROLLOMAXIMUM's service life and the optimise the tilled
field finish, it is very important that the extend/retract outlet (marked:
Red) is set to the float position for field work.

If the outlet (marked: red) is not set to float position, this constitutes in-
correct use and in the worst case may cause the frame to break.
Adjustment of the hydraulic suspension on the middle cross-kill shaft
The hydraulic suspension on the front centre cross-kill shaft (A), transfers part of the
machine's total weight to the axle, but also has the task of helping the axle to vertically
avoid collisions with rocks or when driving on undulating terrain.
The pressure of this sus-
pension is set ex works
to 50 bar (B), which is
the optimum setting un-
der most conditions. The
manometer for this func-
tion is the first (C) of the
two manometers
mounted on the ma-
chine. If it is wished to
change the pressure, the
stop cock (D) on the sin-
gle-acting outlet is
opened (marked: black),
the pressure adjusted
and the cock is closed
again.

If the pressure on the centre axle are not identical with that on the side arm
axles, the pressure in the hydraulic system may be dissipated and the sys-
tem should be refilled with oil. If, however, the earth piles up in front of the
centre axle or the it only clears rocks with difficulty, the pressure is too high
and should be lowered.

Never set the pressure higher than 70 bar, as this may damage the centre
axle and result in very uneven working of the field.

Operating speed
An operating speed of 6-10 km/h is recommended, but always operate according to
conditions.
Power requirement will depend on soil type, terrain and speed. This is a crucial fac-
tor as it determines the working depth with crackerboards and the harrow section.

Adjusting crackerboard
Crackerboard depth is hydraulically
adjustable. The angle of attack of the
tines is manually adjusted via the
spindles (A). To ensure uniform crack-
erboard angle setting, there are num-
bers on the side of the spindles.
The angle set will be retained regard-
less of depth, as the tines are mounted
in a parallelogram array.
•For an aggressive tine setting (vertical) make the spindles shorter.
•For a passive tine setting (horizontal) make the spindles longer.

Raise crackerboard to highest position for adjustment of tine angle.
The tine angle selected depends on the nature of the job. If they are set aggressive-
ly while the depth is set for the upper soil layer, maximum vibration will be created
for fine-crushing of lumps and an optimum smoothing effect.
If the tine setting is more horizontal, it will allow them to avoid obstacles. It will al-
so mean that the tips can move more in the vertical plane, producing an increased
compaction and smoothing effect.
The crackerboard is a flexible unit with a range of applications. When the depth is
set to 5 cm, the vibrating effect of the tines will crush clumps.
