Adjustment of hydraulic weight transfer
Hydraulic weight transfer distributes the weight evenly between all roller sec-
tions.
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.
Fig. 9
2 After short delay
the manometer will react.
Increase pressure to approx.
15
bar (A). This will
transfer some of
the
mid-
section weight
to
the
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.
Excessive pressure
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.
Insufficient pressure
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
must be set in
flow setting
when working in the field.
