Winnowl Verdict

Our product audit of the PowerSmart V8721S Gas Powered Self Propelled Lawn Mower positions it at an AVERAGE (75) Winnowl Index, where the price and capability sit at or above average. The Fair Value index combined with the 45 brand strength from PowerSmart and a Strong Performance rating is a balanced purchase. The Engine Displacement of 170 cc is above the 156.48 and means you should find the engine maintains steady power through standard weekly cuts and moderate overgrowth, while on the lower end the Cutting Width is below the class average and may mean you should effectively balance maneuverability with a path wide enough to clear a standard yard quickly. We recommend staying with this purchase; it captures 2% better cost to Performance than the standard entry in this class.
