The Earthquake Walk Behind String Mower is a gas-powered trimmer designed to tackle heavy brush and thick weeds where regular push mowers struggle. Its 160cc Viper 4-cycle engine provides solid power, making it effective for rough yard conditions. The 22-inch cutting width is wide enough to cover ground quickly, and the 14-inch never-go-flat wheels help it move smoothly over uneven terrain without the hassle of flat tires. Weighing 70 pounds, it’s fairly heavy but stable, which might feel a bit bulky for smaller users or tight spaces. The adjustable handlebar with five height positions allows for comfortable use for different users and tasks.

Starting the mower is straightforward thanks to the hand bail system that keeps the engine running safely and stops the cutting head when needed, reducing the need to restart frequently.
