主权项

1. A concrete removal apparatus comprising:
an arbor frame; wheels supporting the arbor frame; an engine mounted transversely across the arbor frame; a support assembly mounted downward from the arbor frame; a concrete removal device mounted to the support assembly, the concrete removal device having an arbor with a first end and a second end and one or more cutting blades mounted along the arbor; a jackshaft support assembly mounted to the arbor frame; a jackshaft coupled to the jackshaft support assembly and extending transversely across the arbor frame; a jackshaft transmission coupled to the engine to translate an engine moment to a jackshaft moment parallel the engine moment; a first arbor transmission mounted to the arbor frame and coupled between a first end of the jackshaft and the arbor to translate the jackshaft moment to a first arbor moment parallel the engine moment the jackshaft moment; and a second arbor transmission mounted to the arbor frame and coupled between a second end of the jackshaft and the arbor to translate the jackshaft moment to a second arbor moment parallel the engine moment the jackshaft moment.
