Winnowl Index

Winnowl Verdict

At an AVERAGE (71) Winnowl Index, the PowerSmart 21" 140cc Self Propelled Lawn Mower offers top-tier specs, but the lack of value at this price point makes it a difficult choice. You get Strong Performance with this unit, but it comes at the cost of Mediocre Value and only Average Brand Strength to back it up. The PowerSmart 21" 140cc Self Propelled Lawn Mower, 6-Position Adjustable Cutting Height, 3-in-1 with Mulching. Side Discharge. Rear Bagging, Easy Start offers a 6 settings Cutting Height Adjustment that beats the average by 2% and means you should be able to easily dial in the perfect height for your specific lawn and seasonal needs, yet the $389.00 price makes this a poor value for the Gas Powered Self Propelled Lawn Mowers category. We suggest checking out other Gas Powered Self Propelled Lawn Mowers in the class; paying a 5% premium for 11% less value doesn't make sense unless you can't find this level of performance in another product.

Weaknesses

The Strong Performance rating is 7% below the average with highlights like the Cutting Height Adjustment of 6 settings suggests you should be able to easily dial in the perfect height for your specific lawn and seasonal needs, though technical limits eventually mean you will likely notice the engine struggling or "choking" when attempting to mulch thick grass or navigate uphill due to the 140 cc Engine Displacement.

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.
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 4% worse Standard residential precision. Provides enough versatility to handle everything from low spring cuts to tall summer maintenance.
Warranty 2 Years
Average 7% worse Standard industry backing. This 2-year window is the baseline for most reputable residential gas mower brands.
