The MechMaxx 4000 PSI 4 GPM Kohler E-Start Hot Water Pressure Washer Skid Mounted System (Model: HPW40KBT) is a commercial-grade, self-contained mobile cleaning solution designed for heavy-duty industrial, agricultural, and construction applications. Engineered for ultimate mobility, this unit features a massive 245-gallon onboard polyethylene water tank and a fully integrated, powder-coated steel skid frame, allowing it to be easily loaded onto pickup truck beds, flatbeds, or utility trailers.

At the heart of the system is the dependable 429cc, 14 HP Kohler Command Pro CH440 engine. It is equipped with an electric start system and a 12V battery to ensure rapid, hassle-free startup in demanding field conditions. The engine powers a high-performance triplex plunger pump that delivers a consistent flow rate of 4.0 GPM at up to 4000 PSI, providing deep cleaning impact.

For cutting through stubborn grease, caked-on oil, hydraulic fluid, and industrial grime, the integrated diesel burner and seamless steel pipe heating coil heat water up to 200°F in under two minutes. The heating system runs off an onboard 5-gallon diesel fuel tank, regulated by an intelligent temperature control system with a user-friendly control panel. To protect the structural components, the unit is mounted on rubber vibration isolation pads and includes forklift slots and a top lift hook for simple transport and installation.
