Wild Badger Power 40V 21 Cordless Lawn Mower - Battery Workhorse

In this review the Wild Badger Power 40V 21 Cordless Lawn Mower is evaluated as a practical choice for medium-to-large residential lawns that need fewer passes and more consistent cut quality. The single biggest reason to consider it is its combination of a wider 21 in deck and two included 4.0Ah 40V batteries, which together deliver extended runtime and coverage so one person can tackle up to roughly 6,458 sq ft per charge without frequent recharging. The review looks at real-world handling, feature set, and tradeoffs for homeowners deciding between cordless and gas options.

Key Features

• 21 in Max-Coverage Deck: The wider deck covers about 17% more area than an 18 in model, reducing the number of passes needed on medium-to-large lawns.
• 4-in-1 Grass Handling: Bagging, mulching, side discharge and rear discharge provide flexible clipping management depending on lawn conditions and cleanup preference.
• Two 4.0Ah 40V Batteries: Two batteries and a fast charger let users swap packs to extend mowing time and support continuous work across larger yards.
• 7-Position Height Adjustment: The quick dial lets users change blade height to dial in cut quality as grass conditions change through the season.
• 40V Platform Compatibility: The mower uses a battery platform that powers other Wild Badger Power tools, offering long-term value for owners of multiple cordless tools.

Who It's For

This mower is best for homeowners with medium-to-large lawns who want a cordless alternative to gas models and value fewer passes per mow. The 21 in deck and included second battery make it practical for yards up to about 6,458 sq ft per charge, and the 4-in-1 handling suits people who want flexibility between bagging and mulching.

Those with very large properties, commercial needs, or who demand hour-plus continuous runtime without swapping packs should consider more powerful ride-on or larger battery/gas options. Also, if maximum battery life in every condition is critical, note that reported runtimes vary with grass height, terrain and walking pace.

Cons
