Greenworks 80V 21-Inch Self-Propelled Mower: What to Know
The original candidate for this slot was simply "Greenworks 80V 21-Inch Mower," which is a description broad enough to match several different Greenworks SKUs spanning close to a decade of that platform, including older tool-only listings from Greenworks' first-generation 80V mower. We picked out this specific, current-generation model — with aluminum handles and an LED headlight, sold with two 4.0Ah batteries and a rapid charger included — because it's an actively sold, up-to-date listing rather than a legacy SKU.
Greenworks' 80V platform is shared across more than 75 tools in its lineup, and the brushless motor on this mower is built for self-propelled operation rather than the push-only configuration Greenworks also sells at this deck size. Running two 4.0Ah batteries gives you either extended runtime or a backup pack ready to swap in in mid-mow, which matters more on this platform than on 56V or 60V mowers that are more commonly sold as single-battery bundles.
We checked this listing specifically against a February 2026 CPSC recall affecting roughly 554,780 Kobalt-branded 24V and 48V yard tools (made by the same parent company that produces Greenworks) after reports of USB-C charging batteries smoking or catching fire. That recall is limited to Kobalt-branded tools on the 24V/48V platform using USB-C rechargeable batteries — it does not include Greenworks-branded 80V products or this mower's 4.0Ah batteries, which charge through a dedicated Greenworks charger rather than USB-C.
