The invention discloses a caterpillar support deformation device for a caterpillar farmland operation vehicle. The caterpillar support deformation device is characterized in that a driving wheel is mounted above one end of a frame cross member, and a front support wheel is mounted below the other end of the frame cross member and is connected with a hydraulic cylinder mounted on the frame; a rear support frame is welded on the lower side of a certain end of a frame, the certain end of the frame and the driving wheel are positioned on the same side of the caterpillar support deformation device, a rear support wheel is mounted on the rear support frame, a deformation bearing frame supporting seat which is used for mounting a deformation bearing frame is welded in the middle of the frame, a front deformation frame and a rear deformation frame which are respectively connected with the frame and are structurally identical to each other are symmetrically arranged on two sides of the deformation bearing frame, and bearing wheels are mounted on the front deformation frame and the rear deformation frame; telescopic cylinders are arranged in the deformation bearing frame supporting seat, and springs sleeve the telescopic cylinders. The caterpillar support deformation device has the advantages that the hydraulic cylinder can be contracted and extended when the caterpillar farmland operation vehicle crosses a ridge, so that the shape of the middle of a ground-contact caterpillar can be changed, the inclination height of the caterpillar farmland operation vehicle can be lowered, and the operation safety can be improved.
