摘要

Push-and-steer device for an appliance connected to the front-lifting device of a tractor and rolling on the ground, especially for ground-working, and other machines and appliances supported and rolling on the ground on their own supporting and guide wheels, in which movable pushing arms are directed forwards relative to the pushing and to the steering appliance and are fastened to the latter in such a way that their imaginary extensions in front of the appliance intersect diagonally with the tractor-pushing centre line at the ideal pushing point, with the result that an automatic appliance-centring alignment with the tractor-pushing centre line is brought about and, at the same time, an unimpaired tractor steerability is guaranteed.
