The present invention relates to an appliance making it possible to make a normally towed agricultural machine, such as a machine for crops in rows, particularly for vines, self-propelled. This appliance is characterised in that it comprises a chassis 9 carrying a drive wheel 10 which is provided, at its rear part, with means making it possible to articulate it to the chassis 2 of the towed machine 1, in place of the drawbar, about the same vertical axis 6 of the latter. <IMAGE>
