Uses
POWERROLL is a heavy-duty roller designed to follow the surface of the earth opti-
mally across its full width.
Fig. 1
POWERROLL is a five-piece roller, on
which the sections are independent of
each other. Hydraulic weight transfer is
standard on all models.
POWERROLL 1630
POWERROLL is used after sowing to improve sprouting and compress stones.
POWERROLL can also be used for breaking up a compressed soil surface in wheat
fields or grassed areas.
POWERROLL can be fitted with compressed air brakes instead of the standard hy-
draulic brakes.

Side 14
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 soil compression, the mid-section must be horizontal in the di-
rection of travel when lowered and the tractor tow bar must be correctly positioned.
Fig. 3
Before adjusting drawbar to tractor,
basic setting must be correct. Put the
roller on the support leg and check
distance between flange underside
and ground is 40 cm. Adjust drawbar
to tractor from this basic position.
Incorrect drawbar height can cause uneven operation, as the roller will not apply
equal pressure for all sections.
Fig. 4
To achieve optimum drawbar height,
the drawbar can be turned or adjust-
ed up/down until the eye fits the trac-
tor towbar.
Stand POWERROLL on support leg.

Adjustment of hydraulic weight transfer
Hydraulic weight transfer distributes the weight evenly between all roller sections.
1. Once the roller is fully extended and resting on the ground in working posi-
tion, depressurise the fold/extend cylinders (marked: Red/Black). Activate
the cylinder control handles in the opposite direction. Set the raise/lower
cylinders marked white to flow position.
Fig. 15
2 A fluctuation will occur
on one of the manometers after
a brief pause. Increase pres-
sure to 60-100 bar (A/B) on
both manometers. This will transfer
some of the mid-section weight
to the side sections.
3Set control handles for hoses marked red and black to flow position. Flow
setting is necessary to achieve hydraulic weight transfer, allowing the sec-
tions to move independently
4The pressure for hydraulic weight transfer may need adjustment. It can also
be necessary to adjust pressure according to soil conditions.
Excessive pressure
1The pressure on the outer rings of the innermost side sections will be too
high. The rings will be pressed too heavily into the soil leaving a clear groove
after the side sections. The pressure on the outer side sections will also be
too high.
2The mid-sections will not apply sufficient pressure, leaving the soil higher
and not as compressed as the sides. The tractor tracks will also be deeper.
Insufficient pressure
1The pressure on the outer rings of the inner side sections will be insufficient
to give uniform compression. The pressure on the outer side sections will
also be too low.
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, the hydraulic hoses
marked white, red and black must be 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 au-
thorized 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 also
be damaged if operating at excessive speeds in unfavorable conditions.
Power
Power requirement will depend on soil type, terrain and speed.
