The invention discloses a crawler-type tractor reversing device which comprises a constant displacement motor used for transmitting power from the front end. The reversing transmission mechanism is connected with the output end of the constant displacement motor, the reversing transmission mechanism is a closed containing cavity, an oil bath is arranged in the reversing transmission mechanism, and the reversing transmission mechanism is used for reversing power transmission and achieving first-stage speed reduction; the planetary speed reduction mechanisms are symmetrically arranged on the two sides of the reversing transmission mechanism and connected with the output end of the reversing transmission mechanism, and the planetary speed reduction mechanisms are used for speed reduction adjustment to achieve second-stage speed reduction; and the number of the side edge speed reduction mechanisms corresponds to that of the planetary speed reduction mechanisms, and the side edge speed reduction mechanisms are connected with the output ends of the planetary speed reduction mechanisms and used for speed reduction adjustment to achieve third-stage speed reduction. Through the arrangement of the constant displacement motor, the reversing transmission mechanism, the planetary speed reduction mechanism and the side speed reduction mechanism, three-stage speed reduction can be achieved, and the three-stage speed reduction is effective and reliable.
