Abstract

A device for coupling a universal joint shaft to a power take-off shaft (1) of a tractor has a first coupling mechanism (48) that is non-rotatably arranged on the universal joint shaft. A second coupling mechanism (17) is non-rotatably arranged on the power take-off shaft (1) of the tractor. The first and second coupling mechanisms can be non-rotatably coupled to transmit torque. A coupling shield (7) is provided to couple the coupling mechanism (17, 48). The first coupling mechanism (48) is at least indirectly rotationally supported on the coupling shield (7). A locking mechanism (58, 58′) projects from the coupling shield (7). A bracket (2) is attachable on the rear of the tractor. The bracket (2) has at least one locking device (5, 5′) that is displaceable between an unlocked position and a locked position. The locking device (5, 5′) is displaced from the unlocked position into the locked position. The locking device (5, 5′) interacts with the locking members (58, 58′) of the coupling shield (7) to pull it towards the bracket (2). The first coupling mechanism (48) is transferred into a coupling position to couple it the second coupling mechanism (17).
