Agricultural trailer connectable to tractor by shaft - has two angular gearings ensuring small turning radius

摘要

The agricultural trailer has an implement frame supportable on the ground by wheels and connectable to the tractor by a shaft. A driven transmission has an angular gearing associated with the impelement frame and articulated shafts. At the end of the connecting shaft there is a further angular gearing (10) whose input shaft is connected by an articulated shaft (12) to the power take off shaft (13) of the tractor, and whose output shaft is connected to the articulated shaft (11) on the frame side. The angular gearing (9) on the frame side and the angular gearing (10) on the shaft side each have an intermediate shaft whose axes each form a vertical axis. Both angular gearings (9, 10) have a gearing part (23) which is freely swivellable about the vertical axis (17) of its intermeidate shat (17) and which bears the input shafts (15, 21). ADVANTAGE - Small turning radius.
