Whether you run a commercial operation or just need to clean up your backyard, United Rentals has the ideal brush chipper to get the job done. Also known as wood chippers or tree chippers, these valuable machines reduce garden waste like sticks and larger branches. These models feature live hydraulics and AutoFeed, an automatic self-feeding system that increases your productivity and efficiency. This system monitors engine RPM and controls feeding action. This enables the operator to reverse feed material without engaging the cutter wheel while the engine is running.
