Abstract
A linkage for coupling a vehicle to a ground-engaging implement consists of two links, the first link being connected at one end to the vehicle such that it can pivot both around the longitudinal axis of the link and around a line transverse to that axis and connected at its second end to the implement to pivot around a line transverse to its longitudinal axis; the second link being connected in a similar fashion but oppositely to the first link.
