The equipment system has sensor units (20-28) for detecting the positions of the plants in the driving direction in front of a processing device (8,9,12,13,16,17) and for detecting the time point of the detection of the change of the position of an equipment support vehicle (1). The position of the plants is oriented on the equipment support vehicle. The unit for automatic adjustment has units for controlling the working position of a processing element (10,11,14,15,18,19) based on the determined positions of the plants and determined changes of the position of the equipment support vehicle.
