ABSTRACT:
An air cushion mount system is provided between a backhoe system and a vibrator-compactor system for tampering material in a trench which is being filled. This air cushion mount consists of a tire having a wheel rim positioned on the inside rim of a steel pipe having an annular peripheral flange. A flange plate is coupled to the annular peripheral flange of the steel pipe so that the tire can be placed in operative condition or removed from operative condition. The elements of the backhoe are coupled to flanges fixed to the wheel hub. The cushion air mount is coupled by a plate member to the vibrator, and the latter in turn is affixed to a compactor for tampering material in a trench being filled with the same.
