Abstract: An extractor for in situ removal of stump cutting teeth from a cutting wheel. The extractor includes a clamping device having a c-shaped frame with an elongated base member especially adapted to receive and then retain a downwardly stepped land disposed on a head portion of a cutting tooth. The clamping device is mounted on a slide hammer which when activated exerts a sharp pulling force on the head portion of the tooth to efficiently remove the tooth from the cutting wheel without distorting the original shape of the tooth.

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.

Abstract: A stump cutter and earth ripper device having a balanced channel frame chassis, the device including a forward centrally disposed cutting wheel having a plurality of radially extending cutting teeth circumferentially mounted thereon. The frame is supported by a pair of pneumatic tires mounted on individually adjustable and telescopic axles. A unique and rotationally adjustable handle provides accurate control of the device during operation.
