Product Overview

Power through your lawn with clean cuts and zero fuss. The SENIX LSPG-M6 21-inch Gas Push Lawn Mower delivers dependable cutting power with a Briggs & Stratton 140cc 4-cycle engine that starts easy, runs smooth, and requires minimal maintenance — no mixing oil and gas, just prime and pull. Designed for small to medium-sized yards, this mower features a 2-in-1 cutting system that gives you the freedom to mulch or side discharge based on your lawn care needs. The vortex tunnel deck design creates powerful airflow that lifts and finely cuts grass for better mulching performance and cleaner discharge. A 6-position dual-lever height adjustment (1.25" to 3.75") lets you dial in the perfect cutting height, while the 8" front and oversized 11" rear wheels chew through tough terrain and uneven patches with ease. An ergonomic handle reduces hand fatigue during longer mows, and the fold-down design makes for compact, off-season storage in tight garage corners or sheds. The LSPG-M6 is a cut above — built to give you power where it matters, flexibility when you need it, and zero drama in between. Just prime, pull, and mow.
