  "textContent": "The invention relates to a device (1) for a coupling an agricultural implement (3) to an agricultural tractor (2), in which the operation to release the coupling between the agricultural implement and the agricultural tractor can be easily implemented.When the coupling of the agricultural tractor and the agricultural implement is released, first, a control lever (12) of a coupling hook is slid upward against the urging force of a spring (13) until a second guide pin (23) reaches the lower end of a slit (33). Next, the control lever is turned forward around the second guide pin until a bent portion of the upper portion and the lower portion of the control lever comes into contact with a first guide pin (21). As a result, the rear end of a stopper (11) is retracted into a cavity (9) in the hook main body (10) of the device through a second opening (15) so as to slide to the coupling-ball-releasing position, and a groove (28) of the stopper is hooked to a hooking pin (22) so as to be fixed.",
