Product Summary

The Powerhorse 21in. 3-in-1 Self-Propelled Gas Lawn Mower delivers added power and easier handling for larger, sloped residential lawns. A high-output 200cc 4-stroke engine provides consistent cutting performance across a 21in. cutting path, while a 7-position single-lever height adjustment sets cutting heights from 1in.–3in. The 3-in-1 deck supports mulching, rear bagging or side discharge to adapt to changing lawn conditions. A rear-wheel-drive self-propelled system helps maintain steady forward motion and traction on slopes, and the big-wheel layout with 8in. front wheels and 10in. rear wheels supports smooth, confident handling. A 1.2-gallon fuel tank is sized for extended mowing sessions on 1+ acre lawns, and an easy recoil start keeps operation straightforward. Built for demanding residential use, the Powerhorse 21in. 3-in-1 Self-Propelled Gas Lawn Mower is backed by a 2-year limited warranty.
