Power
The Generac 8874
Powered by a 196 cc engine, its aluminum axial cam pump can deliver a pressure of 2900 PSI (around 48 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac 8874 has a cleaning power of 6960 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Generac engine.
The fuel is stored in a tank, which can hold up to 0.8 gallon of gasoline.
Design & Handling
The Generac 8874 offers superb mobility, with a hand truck design and approximate dimensions of D24.4 x W18.9 x H35.5 in. The robust and sturdy steel frame offers longevity to the assembly. The rubber-padded fixed handle adds to the 8874 convenience of transport, while offering a comfortable grip.
The majority of users will be able to maneuver this unit easily, it only weighs 57 lbs. Its 196 cc Generac engine and steel frame account for a good chunk of that weight. The 8874 can still be easily manipulated and maneuvered, thanks to its two 10" never-flat wheels.
