Overview
The B4042HA is a Honda GX390-powered, belt-drive cold water pressure washer rated at 4200 PSI and 4 GPM. It pairs the GX390 with an AR North America industrial triplex pump run at low RPM off a belt drive, which reduces heat and wear versus a direct-drive setup and helps the pump last longer under daily commercial use. It's built for contractors and industrial operators who need high pressure and high flow in a compact, cart-mounted unit. The frame is aircraft-grade aluminum with dual handles and no welds, carrying a lifetime frame warranty. Every unit ships factory-assembled and tested in the USA, ready to run.
