ABSTRACT:
An improved simplified compacting apparatus for mounting on the tool-support boom of a backhoe or other tractor. The apparatus includes a lower member with a convex cylindrical compacting surface which extends through an arc of less than about 180 degrees, preferably less than about 90 degrees, and terminates in front and rear edges. At least one and preferably two upright members are secured to the lower member, preferably to a top concave surface thereof, and pivot mounts are on the upright member to allow pivoting attachment to a tool-support boom. The apparatus is easy to operate and easily reaches edges not reached by many prior devices.
