14 HP Kohler Command Pro Engine 4 GPM 4200 PSI Heavy Duty AR North America

Overview

The D4042KV is a 4200 PSI, 4 GPM cold water pressure washer built around a 14 HP Kohler Command Pro CH440 commercial gas engine direct-driven to an industrial AR pump. It's a heavy-duty unit for contractors who need commercial reliability in a portable package: the aircraft-grade aluminum frame has dual handles and no welds to fail, and it carries a lifetime frame warranty. Low oil shutdown protects the engine, a thermo-sensor prevents pump overheating in bypass, and the unloader is adjustable up to 5,500 PSI. It ships ready to work with a 50-foot 4200 PSI hose, 5000 PSI gun with 42-inch molded-grip lance, and a 10% downstream chemical injector — all on quick connects. A good fit for fleet washing, flatwork, and all-purpose commercial cleaning.
