Detailed Review
The Earthquake Walk Behind String Mower (model 40314) combines the cutting action of a string trimmer with the stability of a push mower. Powered by a 160cc Viper 4-cycle engine, it is built to clear overgrown vegetation, nettles, thick grass, and stubborn brush that standard push mowers cannot manage.
The mower features a one-piece steel deck designed to provide stability while helping to reduce operational vibration. Its trimmer head uses tough nylon line across a 22-inch cutting swath to clear large patches of brush quickly. To move over rough ground and thick foliage, the machine rests on large 14-inch never-go-flat wheels that roll smoothly through dense growth.
Setup out of the box requires virtually zero assembly. You simply unfold the handlebar and tighten the tool-less adjustment knobs. The manufacturer includes starter strings for the trimmer head and 4-cycle engine oil in the box, backed by a 5-year limited warranty. For storage or transport, the adjustable handlebar folds down. On the trade-off side, this gas-powered unit requires standard 4-cycle fuel and oil upkeep and takes up more floor space than a manual or handheld trimmer.
Verdict: The Earthquake Walk Behind String Mower is a practical tool for property owners who need to clear thick brush and overgrown lots. Its simple setup, flat-free wheels, and wide cutting line make it a dependable choice for heavy yard clearing.
