Build a high-use mobile cleaning system around the BE B4213HETBGS truck mount pressure washer. This industrial cold water unit delivers 4.2 GPM at 4200 PSI and is designed to bolt directly to a truck or trailer for a permanent, ready-to-work setup. A Honda GX390 389cc engine provides both electric and recoil start, making frequent startups easier while still giving you a manual backup. Paired with a General TSS1511 P8 triplex pump, it provides the pressure and flow needed for fleet washing, heavy equipment, commercial property maintenance, agricultural equipment, and demanding jobsite cleanup.

The belt-drive system reduces pump speed to 1,450 RPM, helping reduce heat, vibration, and pump wear during extended use. This belt drive truck mount pressure washer uses BE's 238 Truck Mount frame with a powder-coated steel mounting plate and anti-vibration pads for secure installation on a truck or trailer. An external unloader provides adjustable pressure control, while the adjustable detergent injector lets you dial in chemical application for different jobs. The unit includes a 50' x 3/8" braided rubber high-pressure hose, 36" insulated gun and wand, and four quick-connect nozzles, giving professional crews a solid foundation for a dedicated mobile pressure washing rig.
