Uses
MAXIROLL is an extra-heavy roller designed specifically for the mounting of extra
equipment for soil preparation.
MAXIROLL is a three-piece roller, on which the sections are independent of each
other. Hydraulic weight transfer is standard on all models.
MAXIROLL 950/1030 has five axles.
Fig. 1
MAXIROLL 950
MAXIROLL is used prior to sowing to crush lumps and afterwards to prepare for
shooting and to break down stones. MAXIROLL can also be used for breaking up a
compressed soil surface in wheat fields or grassed areas.
Can be fitted with accessories, such as hydraulic crackerboard.
The main purpose of the crackerboard is preparation for sowing. The vibrating ef-
fect of the teeth breaks up lumps, preparing and levelling ploughed and pre-
prepared fields. If the crackerboard is not required, it can be raised and MAXIROLL
used exclusively as a roller.

Connecting and disconnecting
Connecting
Fig. 2
Connect roller to the tractor's fixed
towbar, where drawbar (A) must fit
between the towbar forks.
Insert pin and raise leg.

•Remember to secure towbar pin with split pin or the like.
•Remember to raise the support leg

•If tractor towbar is too short, its lift arms can collide with
the roller's support leg if cornering sharply to the left.
Avoid by extending tractor towbar.
Hydraulics
The roller requires as standard a double-acting and single-acting hydraulic outlet,
where the double-acting is used for extending and single-acting for rais-
ing/lowering.

Setting up
The machine is supplied with factory settings, but fine adjustment will always be
required before use. Numerous adjustment options make the roller more flexible
and ensure maximum use.
Adjusting drawbar height
To achieve uniform rolling, the bar (A, Fig. 3) on the mid-section must be parallel
with the ground and the drawbar (B, Fig. 3) correctly positioned in relation to the
tractor. There are two adjustment options to achieve the optimum position.
Fig. 3
Adjustable drawbar
Incorrect drawbar height can cause uneven operation, as the roller will not apply
equal pressure for all sections.
Fig. 4
To achieve the correct drawbar
height, the drawbar eye can be ad-
justed relative to tractor towbar
height.
Stand MAXIROLL on support leg.
Slacken bolts (A) and adjust drawbar
to tractor.

Operation
Correct operation is vital for optimum use. This applies to working in the field and
for safety. Always ensure you are fully familiar with all safety aspects of the ma-
chine.
Extending and retracting
Extending and retracting the machine must always be performed with tractor
parked.

Before extension and folding, check crackerboard is fully
raised to avoid teeth colliding (see "Accessories, Cracker-
board")
Extending

2Activate extend/retract cylin-
der (marked: Red) to fully ex-
tend side sections.
3Activate raise/lower cylinder to
lower roller to ground. Set
raise/lower cylinder in flow po-
sition (see ”Setting up”).

Before starting rolling, ensure weight transfer is correctly
adjusted (see ”Adjustment of hydraulic weight transfer”).

Relieve pressure from weight transfer to side sections (see ” Adjustment of hydrau-
lic weight transfer”).

If there is a crackerboard fitted, check it is fully raised before
starting folding (see "Accessories, Crackerboard, Operation")
Fig. 11
1. Activate extend/retract cylin-
ders (marked: Red) to full
length, so that the outer side
sections (A) are raised a little.

length and the roller is lifted
off the ground.
Fig. 13
3. Activate the extend/retract
cylinders once more, and
the side sections will retract
(extend/retract cylinders
will now be fully retracted).
4. Activate the raise/lower
cylinder and the roller
will be lowered into the
transport rests.
Adjustment of hydraulic weight transfer
Hydraulic weight transfer distributes the weight evenly between all roller sections.
1. Once the roller is extended, depressurise the extend/retract cylinder
(marked: Red), and then activate the cylinder control handle in the oppo-
site direction (retract cylinder).
Fig. 14
2 After a moment, the the ma-
nometer will flicker. Pressure
will increase (on the plus side
of the cylinder, which will
extend) to about 15 bar
(A)
3Set cylinders to flow setting. Flow setting is necessary to achieve hydraulic
weight transfer, allowing the sections to move independently
4The pressure for hydraulic weight transfer may need adjustment. It can al-
so be necessary to adjust pressure according to soil conditions.
A

MAXIROLL
Page 20
Excessive pressure
1Pressure on the side section outer rings will be too high. The rings will be
pressed too heavily into the soil leaving a clear groove after the side sec-
tions.
2The mid-sections will not apply sufficient pressure, leaving the soil higher
and not as compressed as the sides.
Insufficient pressure
1The pressure on the side section outer rings will not be high enough to
press the outer rings sufficiently down to give an even finish.
2The mid-sections will compress too much, leaving the soil lower than the
sides.

To prolong service life and the final result in the field, MAXI-
ROLL must be set in flow setting when working in the field.

Failure to do so is incorrect use and can cause the frame to
break in the worst scenario.
Check all the accumulators on the machine at least once a
year for leaks and to ensure that the precharge pressure is
set correctly. Contact an authorized DALBO dealer for more
information.
Operating speed
An operating speed of 6-10 km/h is recommended, but always operate according to
conditions.
Increased speed will increase wear, particularly in dry conditions. The rings can al-
so be damaged if operating at excessive speeds in unfavourable conditions.
Power
Power requirement will depend on soil type, terrain, speed and roller rings.
