Abstract
A central swivel joint for optimizing ground adaptation of front machinery of farm tractors has a central beam and a support beam that are rigidly connected to one another to form a constructive unitary part. A support is provided which has a friction bearing in which the support beam is supported. The friction bearing includes a floating bearing and a stationary bearing and is connected to the lubrication system of the motor of the farm tractor for lubrication purposes. The central beam can be in the form of a conventional square beam. Furthermore, the stationary bearing for receiving the axial forces that are exerted onto the central beam is freely accessible as long as the support has not been connected to the oil pan.
