A device for controlling the position of a mountable implement relative to an implement carrier vehicle has a mountable implement (2, 3, 4) which can be moved at a predetermined height by the implement carrier 1 following the ground. A support element (11, 19, 20), is coupled to the mountable implement (2, 3, 4) and can be attached to the implement carrier vehicle (1). A
coupling device (15, 17, 18), is connected to the mountable implement (2, 3, 4) and to the support element (11, 19, 20). The mountable implement (2, 3, 4) is freely adjusted to a lifting position corresponding to the height path relative to the support element (11, 19, 20). An attachment device (6, 7, 8) attaches the support element (11, 19, 20) to the implement carrier vehicle 1 having a lifting device. A sensor determines the actual lifting position of the mountable implement (2, 3, 4) relative to the support element (11, 19, 20). A control device determines the deviation of the actual lifting position from a desired lifting position. The lifting device adjusts the support element (11, 19, 20) to a height position where the mountable implement (2, 3, 4) takes up the desired lifting position.
