Guiding device for e.g. guiding tractor according to predetermined mapping, has actuator controlled by antenna using control station such that lower attachment arm moves with respect to tractor for self-aligning tool relative to tractor

摘要

The device (10) has a global positioning system (GPS) antenna (11) arranged to be placed on an agricultural tool (2), and an actuator (13) arranged to be articulated between a tractor (3) and a ball joint (5). The actuator is controlled by the antenna using a control station such that a lower attachment arm (4) i.e. lifting arm, moves with respect to the tractor for self-aligning the agricultural tool relative to the tractor. Another GPS antenna (12) is arranged to be placed on the tractor and coupled to the former antenna for controlling the actuator.
