Best self-propelled gas lawnmowers for residential lawns

Top pick: the 21-inch self-propelled mower with rear-wheel drive. Rear-wheel drive is what makes a self-propelled mower feel effortless on a normal suburban lawn — it pulls itself up slopes and through thick grass, and the 21-inch deck is the sweet spot for a typical yard. It's the best-rated of the mainstream gas walk-behinds here, and the pull-cord start keeps it simple and low-maintenance.

Who the others suit:

• 22" 170cc 3-in-1 (V8622S) — a slightly wider deck and strong owner ratings if you want to finish a bigger lawn faster.
• ECHO LM-2119SP — the step up for anyone who wants a bigger engine and a brand with dealer service behind it.
• BILT HARD 21" 201cc — the pick if you want the most engine for the money and eight cutting heights.
• 24" high-wheel 6-speed — best for rough, uneven ground and long runs, thanks to the big wheels and variable speed.
• Honda HRX-BE — the premium, buy-it-once choice for a lawn you care about.
• PowerSmart / Sedeke / Reitout — budget starters; fine for a small, flat yard, but weaker ratings.

Skip the Exmark: it's a commercial machine, more mower than a home lawn needs.
