US Patent 7784474 Undercarriage washer

The present invention describes an undercarriage washer including a stabilizing skid plate and an outlet that permits non-vertical fluid discharge. The washer is adapted for use with a high-pressure washing fluid. The undercarriage washer includes a rigid tube and an angled inlet and an outlet. A skid plate is fixedly secured to the tube proximate to the outlet. The skid plate provides sufficient lateral support so that a high-pressure discharge does not rotate the washer stream. A non-vertical discharge angle permits cleaning of large undercarriage parts.
