(3) Pressure spring
There are pressure springs ( 3 ) left and right beside this spindle on both sides of the
lifting unit, these may put an additional load on the depth-control shaft. In case of
need, for instance for very wet ground, this spring pressure may be reduced down to
zero (turn back the lock nut).
6.14.3 Setting lifting depth
As already mentioned several times, ROPA cannot give any generally applicable rec-
ommendations for such work. Experience and specialist agricultural knowledge of
the driver are decisive for the lifting results, because the machine setting exclusively
depends on local conditions.
The lifting depth should be set so that the sugar beets are lifted from the ground with-
out damage. When you see sugar beets on the lifting rollers which are torn off at the
bottom, then the lifter must be set deeper on the respective side (deeper lifting).
In case of very loose and well separable soil, you should lift deeper than indispensably
required. In this way, you achieve much more careful handling of the beets, because
then there is sufficient soil present for strainer wheel cleaning. This soil ensures a
damping effect and helps to avoid damage to the beets.
In case of very sticky soil, you should keep the lifting depth as small as possible. This
loads the cleaning installations substantially less with the soil present in abundance
anyway. In this case, too great lifting depth may easily lead to an increased soil con-
tent on the beets and to reduced throughput of the machine.
