Abstract
An improved stump cutting apparatus and particularly a two-wheel trailer type of stump cutting apparatus employing a hydraulic motor, to, through a drive belt connection, drive a cutting wheel, the hydraulic motor being powered by a hydraulic pump directly mounted on a diesel engine strategically located on a cutting wheel boom, giving the unique benefit of thereby increasing cutting stability due to the presence of the substantial mass of the diesel engine and its centrally-balanced orientation. The cutter boom sweeps side-to-side relative to the hinge head to which it is attached, and the same hinge head provides up and down motion of the cutter boom by owning a pivot located at its bottom end, whose pin unites the same member with the apparatus frame. The present invention operates in combination with a chip-retaining deck that remains elevationally stationary relative to its transporting wheels throughout the entire stump cutting operation.
