A sand fighter with a lightweight, articulated frame is provided. The frame of the sand fighter comprises five frame sections with the center frame substantially shorter in length than the other sections of the frame. Each section includes a shaft with a plurality of evenly spaced tines to till up the heavier moist soil below the surface. The center section includes a hitch adapted to be attached to only two points of a standard three point hitch of the farm tractor. The center section is hydraulically actuated to lift the entire sand fighter up out of the soil. The two sections immediately outboard of the center section, i.e. the intermediate sections, are preferably joined to the center section with hydraulically actuated, hinged joints so that these sections are drawn forward alongside the towing frame for transport of the sand fighter. The outermost sections are preferably manually operated, although these sections may also be hydraulically actuated. The outermost sections collapse alongside the intermediate sections to provide a small profile for transport of the sand fighter.
