ABSTRACT:
A self-propelled soil stabilizer machine employs a heavy-duty single horizontal rotor for pulverizing and mixing soil it passes over. The rotor is driven by hydraulic motors which are mounted at the rotor ends and operated by a hydraulic pump (engine driven) which is hydraulically coupled to a hydraulic traction pump (also engine driven) which propels the machine. Each hydraulic motor is mounted for rapid removal and replacement thereof. Toward this goal, each end of the rotor is hollow, whereby the drive shaft of each hydraulic motor can be releasably accepted in one of the ends of the rotor in a spline connection therebetween. Overloads on the rotor system are automatically sensed by a closed-loop hydrostatic system and result in a direction in the speed of machine travel until the load on the rotor diminishes. A hydraulic rotary servo-valve and mechanical feed back system automatically controls the rotor to maintain it at a preset depth and provides a visual read-out of depth.
