ツチ装置における出力軸自動連結構造。 In a four-point hitch device for an agricultural tractor that automatically connects the three-point link supported on the hitch frame of the agricultural tractor and the output shaft to the work machine, the work machine side output is connected to the tractor's PTO shaft via a universal joint. A drive-side clutch pawl that engages with a passive-side clutch pawl fixed to the input shaft of the working machine is integrally fixed to the shaft end, and the intermediate shaft of the universal joint is divided into two parts to be freely expandable and retractable in the axial direction. Output in a four-point hitch device for an agricultural tractor, characterized in that the drive-side clutch pawl, which is integral with the shaft, can move forward and backward by a predetermined amount in the direction of the PTO shaft, is always urged toward the working machine side by a spring, and is supported on the hitch frame. Axis automatic connection structure.
