The invention discloses an articulated steering mechanism for an agricultural tractor. According to the articulated steering mechanism, a traction pin hole is formed in one end of a traction shaft, a traction pin penetrates through the traction pin hole and is vertically installed between two traction pin sealing covers, the axis of the traction pin is vertical to the axis of the traction shaft, and the two traction pin sealing covers are installed on an upper traction pin fixed plate and a lower traction pin fixed plate respectively; the other end of the traction shaft penetrates through a traction shaft sleeve, the two ends of the traction shaft sleeve are installed on a front traction shaft sleeve fixed plate and a rear traction shaft sleeve fixed plate, and the left end and the right end of each of the front traction shaft sleeve fixed plate and the rear traction shaft sleeve fixed plate are fixed on a rear frame crossbeam respectively; the tail end penetrating through the traction shaft sleeve, of the traction shaft, is screwed by a traction shaft nut; and limit plates are installed at the two sides of the front end of the traction shaft, and limit nails are installed on the front traction shaft sleeve fixed plate and corresponding to the limit plates. The articulated steering mechanism disclosed by the invention improves the adaptability of front wheels to a road surface, improves the road holding force of the tractor, and reduces the torsional moment stressed by the traction shaft, so that the articulated steering mechanism is small in deformation and low in steering resistance.
