PowerSmart 21ft Gas Lawn Mower - 140cc Briggs & Stratton

In this review the PowerSmart 21' Gas Lawn Mower is evaluated as a practical, no-frills option for homeowners with small to medium yards who want a reliable push mower without electric hookups. The biggest reason to consider it is the USA-made Briggs and Stratton E550 140cc engine with Prime 'N Pull, which provides straightforward starting power and quieter operation than many cheaper engines. For buyers who value a durable steel deck, simple folding storage and three mowing modes, this mower delivers strong everyday performance at a modest price.

Key Features

• Reliable engine: The Briggs and Stratton E550 140cc engine gives steady power and uses a Prime 'N Pull system so cold starts are easier for the typical homeowner.
• 21-in steel deck: The all-steel deck resists wear and provides a wide cutting swath so you can finish a small yard more quickly.
• 3-in-1 versatility: Mulch, rear discharge or bag clippings with the included 1.4-bushel bag to switch between soil nourishment or a manicured look.
• Easy assembly and storage: Arrives fully assembled in the box and folds quickly for compact storage with minimal effort.
• Adjustable cutting height: Six-position rear wheel height adjustment lets you change the cutting height quickly to suit grass conditions and preference.

Who It's For

The PowerSmart 21' is best for homeowners with small to medium lawns who prefer a manual push mower with a proven Briggs and Stratton engine and want the flexibility of mulching, bagging or rear discharge. It fits buyers who value simple operation, quick assembly and compact folding for garages or sheds.

People with very large properties, those who need self-propelled drive or commercial-grade runtime, and users who expect heavy-duty duty-cycle performance should consider a larger, self-propelled or riding mower instead, as this model is designed for residential use and moderate workloads.
