Abstract: A hydraulic stump cutting and earth digging apparatus including a balanced main supporting frame of a vehicle member and an adjustable telescopic channel frame cutter boom, the boom comprising a forward centrally disposed rotatable cutting wheel having a plurality of radially extending cutting teeth circumferentially mounted thereon. The channel frame cutter boom further includes a hydraulic motor contiguously mounted with the cutting wheel and having a common axis for rotation. A double pump and motor for circulation of hydraulic fluid to the hydraulic components of the apparatus is mounted on the main supporting frame thereby providing a telescopic cutter boom which is lighter in weight and more accessible to tighter places than conventional hydraulic stump cutters.
