Universally moving support for drawbar - operates with ball bearing held in spherical socket axially under shaft

摘要

The drawbar wheel is provided by a ball and socket arrangement in which a plastics ball (12) is held in the socket (9) at the bottom of the height adjustable support shaft (8). The ball is held inside the socket by a sealing gasket (31) at the bottom of the socket. The ball allows movement in any direction, while the central mounting of the socket ensures that the thrust is central down the shaft, without any bending moment.
