Adjustments of hydraulic weight transfer
The hydraulic weight transfer distributes the weight evenly on the drum sec-
tions.
1. After the drum is unfolded, pressure is taken out of the unfolded and
folded cylinders (marked: Red), after which the cylinders' control lev-
er is activated in the opposite direction.

2 After a moment, the pres-
sure will appear on the pres-
sure gauge.
The pressure
will increase approx. 30 bars (A).
This means that some of
the mid-section weight
is transferred to the side sec-
tions.
3 The operating levers are then set in float position. The float position
is required to achieve a hydraulic weight transfer in which the sec-
tions are individually movable
4 It may be necessary to adjust the pressure for the hydraulic weight
transfer. Likewise, it may be necessary to drive with less or more
pressure, depending on soil conditions.
Too much pressure
1 The pressure on the outer edges of the side sections will be too great.
The rings are pressed too much into the soil and leave clear tracks
outside the side sections.
2 The mid-section packs too little, which can be seen as the soil under
the mid-section is higher and not as compressed as under the side
sections.
Too little pressure
1 The pressure on the outer edges of the side sections will not be large
enough to provide a uniform seal.
2 The mid-section packs too much, which can be seen as the soil under
the mid-section is more compressed than under the side sections.

For the durability of the machine and the result in the ground, it is very
important that the cylinders are placed in
float position
during work
in the field.
