ABSTRACT:
A soil stabilizer comprises a self-propelled vehicle, a rotor having soil-working teeth, and a motor for driving the rotor. The motor is reversible to drive the rotor in opposite directions. The rotor includes tooth holders, each having generally oppositely directed tapered sockets. A tooth is received in one of the sockets so as to project in the direction of rotation. The rotor can thus be effectively utilized in either direction of rotation. The sockets are coplanar and intersect so that the zone of intersection forms an interruption in the tapered engagement between the tooth and socket intermediate the ends thereof to compensate for manufacturing variations in the tapered fit.
