The EB4040HA belt-driven cart-mounted pressure washer from Amazing Machinery is designed to provide pump longevity. The belt is attached to a pulley system on the engine, which – when combined with the lower rpm of the belt-drive pump – allows the pump to run cooler. It features a Honda GX390 commercial-grade engine, AR pump rated at 4,000 psi at 4 gpm, adjustable pressure unloader valve, aircraft-grade aluminum frame, low-oil shutdown and a thermo-sensor that shuts the unit down to protect it from overheating. Accessories include a chemical injector with quick-connects, a gun and wand, 50-foot high-pressure hose, four color-coded spray nozzles and a color-coded chemical nozzle. 800/504-7435; www.amazingmachinery.com.
