Winnowl Verdict
The PowerSmart 21-Inch 140cc B&S Engine Self-Propelled Lawn Mower just bottomed out our audit with a DEFICIENT (47) Winnowl Index—the kind of score we only see in "shelf-filler" products. This product fails across all three indicators where Average Brand Strength, Mediocre Performance, and Mediocre Value are strong reasons to consider a different product. The specs show the PowerSmart 21-Inch 140cc B&S Engine Self-Propelled Lawn Mower – 6-Position Adjustable Cutting Height, 3-in-1 Mulching, Side Discharge, and Rear Bagging, Easy Start has a Engine Displacement of 140 cc, which is 11% below the 156.50 class average and you will likely notice the engine struggling or "choking" when attempting to mulch thick grass or navigate uphill. We'd recommend you look at other Gas Powered Self Propelled Lawn Mowers with better Performance and stronger value.

The Winnowl Lab Report
| Specification | Value | Rating | Vs. Average | Winnowl Insight |
|---|---|---|---|---|
| Engine Displacement | 140 cc | Mediocre | 15% worse | Entry-level displacement. Engines in this range (typically 140cc) lack the torque required for heavy-duty residential tasks. |
| Warranty | 3 Years | Strong | 45% better | Standard industry backing. This 2-year window is the baseline for most reputable residential gas mower brands. |
| Cutting Width | 21 inches | Average | 2% worse | Full-size residential benchmark. The 21-22 inch deck is the gold standard for balancing speed, storage, and handling. |
| Cutting Height Adjustment | 6 settings | Average | 5% worse | Standard residential precision. Provides enough versatility to handle everything from low spring cuts to tall summer maintenance. |
