Can this pressure washer be shipped to California?

No — this model is not CARB compliant and cannot be sold in California. A California-compliant upgrade is offered as an option, so check the product options or contact us if you're a CA buyer.

Is a battery included for the electric start?

No, the battery is not included, but a marine-grade battery box is. The unit's 20-amp charging system keeps your battery charged while running, and the Kohler engine also has a manual backup start.

What pump does this unit use, and are other pumps available?

It ships with the AR Viper VV4G42G industrial direct-drive pump. GP (General Pump) and Cat pump options are also available if you have a shop preference for parts and service.

Does it arrive assembled and ready to use?

Yes — every unit is completely factory assembled and tested in the USA, delivered ready to operate. It includes the 50 ft hose, gun/wand, cleaning tips, and a chemical injector with quick-connect; you just add fluids and a battery.

Overview

This is a portable commercial hot water pressure washer delivering 4200 PSI at 4 GPM, powered by a 14 HP Kohler Command Pro 440cc engine with electric and manual start. The engine runs an AR Viper industrial direct-drive pump (VV4G42G), and a Beckett diesel burner with adjustable thermostat control heats the water through a schedule 80 coil with stainless steel wrap, fed by an 8-gallon onboard burner fuel tank. It's built on an HD US steel roll-cage frame with a lifting hook, 13-inch flat-free tires, and a compact 39" L x 31" W x 49" H footprint, so one operator can move it around a job site. Every unit ships factory assembled and tested in the USA, ready to run. Not for sale in California (a CARB-compliant upgrade is available).
