Adjustment of hydraulic weight transfer
Hydraulic weight transfer distributes the weight evenly between all roller sec-
tions.
Excessive pressure
Insufficient pressure

1. Once the roller is unfolded, relieve pressure in the extend/retract cyl-
inders (marked: Red), and activate cylinder control handle in the oppo-
site direction.
2 After short delay
the manometer will react.
Increase pressure to approx.
15
bar (A). This will
transfer some of
section weight
side sections.
3 Set control handle to flow setting. Flow setting is necessary to achieve
hydraulic weight transfer, allowing the sections to move independently
4 The pressure for hydraulic weight transfer may need adjustment. It can
also be necessary to adjust pressure according to soil conditions.
1 Pressure on the side sections will be too great, leaving clear tracks in
the soil.
2 The mid-sections will not apply sufficient pressure, leaving the soil
higher and not as compressed as the sides.
1 The pressure on the extremities of the side sections will be insufficient
to give uniform compression.
2 The mid-sections will compress too much, leaving the soil lower than
the sides.
To prolong service life and the final result in the field, Maxiroll
flow setting
must be set in
