Overview

The B4550HGE is a cold-water, belt-drive commercial pressure washer that puts out 4.5 GPM at 5000 PSI from an electric-start Honda GX630 engine paired with a low-RPM General Pump. The 4-groove cog 3VX V-belt drive keeps pump speed down, which cuts heat and wear for longer service life than a comparable direct-drive unit. It arrives completely factory assembled and tested in the USA, ready to mount and tank feed on a trailer, deck, or truck bed, with a remote six-gallon poly fuel tank and a marine-grade battery box. It's built for contractors who need high pressure and high flow together — fleet washing, concrete, and heavy commercial cleaning. Not for sale in California as configured; a CARB-compliant upgrade is available in the options. Battery not included.

Frequently asked questions

Yes — it's built to tank feed and comes ready to mount on a trailer, deck, or truck bed. It's a skid-style unit with a remote six-gallon poly fuel tank, delivered completely factory assembled and tested so it's ready to operate.

No — as configured it is not for sale in California because the remote poly fuel tank is not CARB evaporative compliant. A California-compliant upgrade is available; see the product options or contact us to spec it.

Belt drive lets the pump run at lower RPM than the engine, which reduces heat and wear and extends pump life — the reason this unit pairs the Honda GX630 with a low-RPM General Pump through a 4-groove cog 3VX V-belt. The belt cover removes with a single bolt and tension is easily adjustable.

Yes — this unit features electric start with a marine-grade battery box, plus EZ-Start for easier starting. It also includes low-oil shutdown to protect the Honda GX630 engine.
