PowerSmart 21 in. Gas Lawn Mower with 144cc OHV Engine - Reliable

Our review of the PowerSmart 21 in. gas lawn mower finds it best suited for homeowners with small to medium yards who want a straightforward, powerful push mower that starts easily and covers ground quickly. The single biggest reason to buy is the 144cc OHV engine paired with a 21 in blade, which delivers consistent cutting performance and enough torque to handle thick grass without constant re-passes. Assembly is generally simple and once running the mower feels capable and efficient for routine mowing tasks.

Key Features

• 144cc OHV engine: Provides steady, high-efficiency power and an auto choke that makes starting the mower easier on the first pull.
• 21 in cutting blade: The wider blade covers more turf per pass so users can mow faster and finish jobs in fewer passes.
• 2-in-1 steel deck: Durable all-steel construction supports both mulching and side-discharge modes for flexible grass management.
• Adjustable cutting height: Six-position dual-lever adjustment lets you choose a cut between 1.5 in and 3.9 in to suit lawn type and season.
• Compact storage: Foldable design reduces storage footprint by about 70% so it tucks away easily in a garage or shed.
• Large rear wheels: 10 in rear and 7 in front wheels roll smoothly over uneven ground and reduce operator effort.

Who It's For

The PowerSmart 21 in. mower is aimed at homeowners with small to medium-sized yards who want a reliable gas mower with enough power to handle dense grass. It is a practical choice for buyers who value easy starting, a 21 in cutting width for faster work, and the flexibility of mulching or side-discharge.

This mower is less well suited for very large properties where a self-propelled or riding mower would save time, or for buyers who expect premium all-metal fittings everywhere; some users reported mixed impressions about certain plastic parts and long-term component durability.

Pros & Cons

Pros

• Strong and reliable starting thanks to the 144cc OHV engine and auto choke.
• Efficient 21 in blade reduces mowing time compared with narrower walk-behinds.
• 2-in-1 steel deck gives useful mulching and side-discharge options for different lawn care needs.
• Compact fold-down design makes storage easy for small garages or sheds.

Cons

• Some customers report mixed build quality with a few plastic components feeling less robust, which may affect long-term durability.
• Not self-propelled, so it requires more physical effort on inclines or very large yards.
