Karcher 1.107-520.0 : HD 4.0/40 GeB AR Cold Water Gas Pressure Washer with Honda Engine | 4.0 GPM 4000 PSI

Key Product Features

• Genuine Kärcher HD Gas Plus Pressure Washer: Original Kärcher professional pressure washer, part number 1.107-520.0, also listed as HD 4.0/40 GeB AR, designed for commercial cold water cleaning with electric start convenience, AR pump performance, and belt-drive durability.
• 4.0 GPM High-Flow Water Output: Produces 4.0 gallons per minute, giving operators strong rinsing volume for quickly removing mud, grease, detergent residue, road film, algae, soil, and heavy debris from large surfaces, vehicles, and equipment.
• 4,000 PSI Heavy-Duty Cleaning Pressure: Delivers 4,000 PSI of cleaning force, making this machine suitable for tough commercial jobs such as concrete washing, fleet maintenance, construction equipment cleaning, agricultural machinery washdown, shop cleanup, and loading dock cleaning.
• Honda GX390 Electric Start Engine: Powered by a commercial-grade Honda GX390 engine with electric start, this unit gives operators dependable outdoor performance and easier starting compared with recoil-only models. The electric start design is especially useful for frequent daily operation and demanding jobsite schedules.
• AR RRA4G40N Belt-Drive Pump: Equipped with a durable AR RRA4G40N belt-drive pump, providing a professional AR pump configuration built for smooth water delivery, dependable pressure output, and frequent commercial use.
• Belt-Drive Durability Advantage: The belt-drive system helps reduce pump speed, heat, vibration, and direct engine stress. This supports longer pump service life and makes the unit a strong choice for contractors and facilities that run pressure washers regularly.
• Electric Start + Belt Drive Combination: The GeB configuration combines two important upgrades: electric start for easier operation and belt-drive pump construction for improved durability. This makes it more convenient than recoil-start models and better suited for frequent use than many direct-drive pressure washers.
• HD Gas Plus Series Platform: Kärcher’s HD Gas Plus lineup is built with Honda engines and top-quality pump options, including Leuco, AR, and GP pump configurations, for professional cold water pressure washing.
• Modular Weld-Free Aluminum Frame: The Gas Plus platform uses a durable, weld-free aluminum frame that helps resist corrosion while keeping the machine practical for transport, storage, and daily jobsite use.
• Professional Jobsite Mobility: The portable frame and commercial wheel layout help operators move the pressure washer across pavement, gravel, shop yards, driveways, sidewalks, loading areas, farms, and outdoor commercial worksites.
• 50 ft Non-Marking Hose: Dealer listings note a 50 ft non-marking hose, giving operators useful reach around vehicles, equipment, concrete pads, shop floors, sidewalks, and commercial entry areas while helping reduce surface marks.
• Cold Water Gas-Powered Performance: Provides strong pressure washing without the added cost or complexity of hot-water equipment, making it ideal for removing dirt, mud, mildew, dust, grime, and general outdoor buildup.
• Excellent for Concrete and Hard Surfaces: Ideal for sidewalks, driveways, patios, parking pads, loading docks, shop entrances, retaining walls, pavement, and other durable surfaces that need high-pressure cleaning.
• Great for Equipment and Vehicle Cleaning: Suitable for trucks, trailers, tractors, service vehicles, landscaping equipment, construction tools, farm equipment, municipal vehicles, and heavy maintenance machinery.
• Strong Contractor-Level Output: The combination of 4.0 GPM and 4,000 PSI gives professionals both high cleaning impact and strong rinsing volume for demanding commercial cleaning jobs.
• Gas-Powered Outdoor Flexibility: The Honda gasoline engine allows operators to clean remote outdoor areas without relying on electrical outlets, making this model practical for farms, construction sites, municipalities, schools, industrial yards, and mobile contractors.
