A soil stabilizer for treating ground surface includes a stabilizer frame, a rotor rotatably mounted thereon, the rotor being movable such that the rotor may engage various depths of earth, a rotatable axle, and a track apparatus mounted on the rotatable axle, the track apparatus supporting the stabilizer frame and providing for movement of the stabilizer frame and rotor across the ground surface. The track apparatus may include a continuous flexible track having an upper length and a ground-engaging lower length and including an inner surface, an axle wheel mountable to the rotatable axle for rotational movement therewith, the axle wheel engaging the inner surface of the flexible track along the upper length to drive the flexible track in response to rotation of the axle, and a track apparatus frame for mounting the axle wheel.
