The invention discloses a caterpillar ridge crossing deformation device for a caterpillar farmland operation vehicle. The caterpillar ridge crossing deformation device is characterized in that a frame comprises a frame cross member and an auxiliary frame cross member, a driving wheel is mounted above one end of the 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 the frame, the certain end of the frame and the driving wheel are positioned on the same side of the caterpillar ridge crossing deformation device, a rear support wheel is mounted on the rear support frame, a deformation bearing frame is arranged above a deformation bearing wheel, a front deformation frame and a rear deformation frame which are structurally identical to each other are symmetrically arranged on two sides of the deformation bearing wheel, are respectively connected with the deformation bearing frame by telescopic mechanisms and are respectively connected with the frame, and bearing wheels are respectively mounted on the front deformation frame and the rear deformation frame. The caterpillar ridge crossing 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 running safety can be improved.
