The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Briggs & Stratton 20507 in use

The Briggs & Stratton 20507

Utilizing a powerful 420cc (13.5 hp) engine, this machine's triplex pump can deliver a pressure of 4000 PSI (around 67 times stronger than a standard garden hose) and a flow rate of up to 4 GPM (values claimed by the manufacturer). Thus, the Briggs & Stratton 20507 achieves a cleaning power of 16000 Cleaning Units.

The Briggs & Stratton 2100 Series™ engine of this gas-powered pressure washer is initiated by a classic pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 1.75 gallon.

Design & Handling

Characterized by its wheelbarrow layout, the Briggs & Stratton 20507 provides improved mobility and stability, facilitating easy movement and steadfast operation for effective cleaning results. Built to endure, the steel tubing frame ensures the assembly's longevity by providing stability and safeguarding internal components under all working conditions. The handle adds to the 20507 convenience of transport.

With its hefty 141 lbs, this unit isn't exactly easy to handle, making manual lifting and transport quite a daunting task, especially on uneven terrain. The major reasons for its heavy weight are its 420cc Briggs & Stratton 2100 Series™ engine, the triplex pump and steel tubing frame. However, the incorporation of two 12" never-flat wheels makes navigating the 20507 less cumbersome, even on uneven terrain.

Main Features

Along with the Briggs & Stratton 20507 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Despite the absence of a soap tank, detergent supply is facilitated through the use of a siphon hose. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
  • Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 50 ft ⌀3/8" high-pressure hose to be neatly stored when idle.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • Nozzles: The following table provides information on the 5 included nozzles and their recommended surface uses.
