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.
An improved stump cutting apparatus of the type having a wheel supported frame, said frame having at least a first and a second frame member intersecting in an essentially "T" configuration, said first frame member having a forwardly projecting tongue for towing, a rotating cutting wheel having a plurality of radially extending cutting teeth circumferentially secured about the periphery of said cutting wheel, said cutting wheel mounted on a cutting boom having a first and second end and positioned rearwardly of said frame, a power drive means for powering said cutting wheel and having at least a hydraulic pump and motor wherein the improvement comprises:
A hydraulic stump cutting apparatus comprising in combination:
