Fertilizer spreader has disks driven by tractor engine whose speed of rotation can be adjusted without changing tractor speed using gearbox and cardan joints

摘要

The fertilizer spreader has disks (herissons) which are driven by the tractor engine. Their speed of rotation can be adjusted without changing the tractor speed using a gearbox with two input shafts (3, 4), each of which can independently be connected to the engine by a cardan joint (2). It also has two output shafts (7, 8) which can be connected independently to the disks by a second cardan joint (5).
