Detailed Review
The PowerSmart 21-Inch Self-Propelled Gas Lawn Mower provides dependable cutting power for homeowners maintaining medium to large yards. Powered by a 170cc OHV gas engine, it tackles tough grass conditions while the self-propelled drive system reduces the physical effort needed to push across your yard.
Built around a durable 21-inch steel deck, this mower cuts a broad path with every pass to speed up yard work. Its self-propelled rear-wheel drive works together with large 10-inch rear wheels, delivering the traction and maneuverability required to handle uneven terrain and yard slopes smoothly.
You can tailor how you handle lawn clippings using the 3-in-1 setup, which lets you mulch directly onto the turf, use the rear discharge for quick clearing, or collect clippings in the included 1.4-bushel bag. A single lever lets you quickly switch between 6 height settings ranging from 1.5 inches to 3.9 inches to match changing seasonal grass heights.
Because this is a gas-powered machine with a 170cc OHV engine, it requires standard gas engine care and fuel handling. Additionally, the 1.4-bushel collection bag will need frequent emptying if you choose to bag clippings over a larger lawn area.
Verdict: The PowerSmart 21-Inch Gas Mower is a strong match for property owners with medium or large lawns, especially those with slopes or uneven ground. Its self-propelled rear drive, wide steel deck, and versatile 3-in-1 clipping options make routine yard care fast and straightforward.
