Intelligent, hydraulic pump drive

For the pump drive, boom hydraulics and the DoubleTrail steering, with the proviso that a Load-Sensing system is necessary on the tractor, all the functions can be operated especially comfortably via an ISOBUS terminal. The positive benefit also is the automatic setting of the pump speed with regard to each operational situation. When operating in the field, the pump runs at a gentle 480 rpm; sufficient capacity for the agitation and normal application rates. Whilst travelling on the road, the pump speed is automatically reduced to 400 rpm as the only demand is for a supply to the agitation. When filling via the suction hose, then the full pump capacity is provided by increasing the speed to 540 rpm. All the values are pre-selected once by the user but it is also possible to change them at any time. The system relieves the stress on the operator and provides a particularly sensitive connection to the pump and the diaphragms.
