Spotted this at clearance: the Greenworks 80v Self Propelled Mower (21″) is marked down with item number 1992723. If you’ve been waiting to ditch your gas mower for battery power, this might be your moment.
This is a 21-inch self-propelled lawn mower from Greenworks’ 80-volt lineup, which sits at the top of their cordless tool ecosystem. The self-propelled feature means the mower drives itself forward—you’re just steering and guiding, not pushing. It’s designed to handle typical suburban lawns without the noise, fumes, or maintenance headaches of gas-powered alternatives.
Whether this is a solid deal depends on what you value. Battery-powered mowers from reputable brands typically command premium prices, and Greenworks 80v tools are generally well-regarded for power and runtime. If you’re already invested in the Greenworks 80v battery system, this could be particularly worthwhile since you can share batteries across tools. For someone starting fresh, factor in that you’ll need the battery and charger setup if they’re not included.
We’re seeing this in mid-June, which is peak mowing season—so this isn’t a typical end-of-season clearance situation. More likely, Costco is making room for a newer model or simply decided not to restock this particular configuration. Either way, clearance lawn equipment moves fast, especially quality battery-powered options, so inventory is probably limited.
