Tackle hills, uneven terrain, and thick grass with the PowerSmart 21″ Gas Self-Propelled Lawn Mower. Powered by a reliable 170cc OHV engine that starts in 1-2 pulls, this mower delivers consistent performance all season long without bogging down.

Why Choose PowerSmart?

The rear-wheel drive self-propelled system with 10″ large wheels grips slopes and rough terrain so you guide, not push. The 21″ alloy steel deck handles thick turf in a single clean pass, while 6 height positions (1.5″–3.9″) adjust with one lever in seconds. The 3-in-1 cutting system lets you switch between bagging, mulching, and rear-discharge without tools.
