6.4 Tractor requirements for the fertiliser spreader
6.4.1 mechanical drive of the fertiliser spreader
Tractor requirements

A single-acting control valve
6.4.2 Hydraulic drive of the fertiliser spreader
constant flow
For the hydraulic drive of the AXIS-HT 50.2 EMC fertiliser spreader, the hydraulic
system of the tractor should deliver an additional volume flow of at least 65 l/min
at 180 bar .
For the hydraulic drive of the AXIS-HT 30.2 EMC fertiliser spreader, the hydraulic
system of the tractor should deliver an additional volume flow of at least 45 l/min
at 180 bar .
If the volume flow from the tractor is not sufficient for the load transfer vehicle and
the attached fertiliser spreader, the load transfer vehicle can load the spreader
only if the spreader is switched off (e.g. in the headlands).
In this case use the QUANTRON-A control unit to set the load transfer function
to
semi-automatic .
Load sensing
If the tractor is equipped with a load sensing hydraulic system, you can control
the hydraulically driven fertiliser spreader. In case of problems with load sensing
(e.g. juddering of the spreading discs), set the drive of the fertiliser spreader to
constant flow.
