Abstract

A vehicle includes an engine and a curb cutting assembly. The curb cutting assembly is mounted on the chassis. The curb cutting assembly includes a main beam, a saw assembly, vertical cylinders, horizontal cylinders, pivot cylinders, and a pump. The vertical cylinders are configured to raise and lower the main beam in a vertical direction. The horizontal cylinders are configured to extend or retract the main beam in a lateral direction. The pivot cylinders are configured to extend or retract to pivot the main beam, the horizontal cylinders, and the vertical cylinders about a longitudinal direction. The pump is configured to be driven by the engine and pressurize hydraulic fluid for the saw assembly, the vertical cylinders, the horizontal cylinders, and the pivot cylinders.
