An improved subsoil ripping device is disclosed in which ripper teeth are mounted on the sides of a tracked, crawler-type prime mover approximately opposite the center of mass. The frames carrying the ripper mechanisms are most conveniently mounted on the arms of a conventional bulldozer blade. In order to increase resistance to lateral forces acting on the ripper teeth, the frames may be bridged by a rigid arch. Alternatively, they may be braced by a strut acting between the ripper assembly and the tractor frame. If this latter arrangement is used, the ripper assemblies are preferably hinged to the blade arms to permit full normal blade movement. A ripper made according to the present teaching is especially useful when operating on uneven or debris covered ground. It does not tend to rake up debris, and thus does not require time and fuel for clearing the teeth. Because of the location of the teeth, the prime mover is easier to steer and a rip of more uniform depth can be maintained.
