The invention belongs to the technical field of crawler-type draggers, and particularly relates to a width-adjustable amplitude-variable crawler-type dragger which comprises a dragger body, a driving unit and a transmission unit, the driving unit and the transmission unit are arranged on the dragger body, and the transmission unit further comprises an auxiliary crawler located in a gap of a main crawler and a telescopic mechanism driving the auxiliary crawler to move in the horizontal direction. The fixed end of the telescopic mechanism is fixedly connected with the tractor body, the telescopic end of the telescopic mechanism is hinged to a rotating shaft of the auxiliary crawler belt, the auxiliary crawler belt stretches out and draws back in a reciprocating mode through the telescopic mechanism along the horizontal plane perpendicular to the moving direction of the tractor, and a plurality of crawler belt plates are arranged on the circumferential surface of a chain of the auxiliary crawler belt through a folding mechanism. The track shoe stretches back and forth by being perpendicular to the surface of the auxiliary track through the folding mechanism. According to the traction machine, the auxiliary tracks capable of being unfolded or hidden are additionally arranged in the gaps of the main tracks, so that the width of the tracks of the traction machine is adjustable, and the traction machine is suitable for working sites in different environments.
