BLACK+DECKER vs Greenworks Lawn Mower (2026)

The Greenworks 80V 21-Inch Self-Propelled ($699.99) is the premium option on this page and the most capable battery-powered lawn mower in the comparison. The 80V brushless motor delivers power approaching gas mowers, and self-propulsion eliminates the physical effort on slopes and larger lawns. For buyers exiting their last gas mower and not wanting to return, this is the most compelling transition point. Against the Greenworks Pro 80V ($479.99) at $220 less, the key question is whether the additional battery capacity and features justify the premium. The base 80V ($699.99) includes a larger battery and potentially additional accessories depending on the specific configuration — but both use 80V brushless motors on a 21-inch deck. Check current bundle contents carefully before purchasing. Against the BLACK+DECKER 3-in-1 ($74.92) at one-tenth the price, these represent entirely different product categories. The BLACK+DECKER is for small-space grass management; the Greenworks 80V is for actual lawn maintenance. The honest limitation of the 80V premium model is the 4.0Ah battery covering approximately 1/3 acre per charge — larger lots require either a second battery or mid-session charging. Service and repair are also harder to source than major gas brands like Honda or Toro.

The Greenworks MO40L410 40V Push Mower ($369.99) is the mid-tier cordless option on this page — removing the gas and cord without the premium price of the 80V self-propelled models. The 20-inch cut width is narrower than the 21-inch 80V models but covers small to medium yards efficiently with push mowing. The 5-position height adjustment handles a range of grass heights, and battery compatibility with the Greenworks 40V platform allows battery sharing across other tools. Against the Greenworks 80V Self-Propelled models ($479.99 and $699.99), the 40V push model costs $110–$330 less by trading higher voltage and self-propulsion. For flat yards under 1/4 acre, push mowing is not a significant burden, and the 40V battery provides adequate runtime. For sloped yards or lots over 1/3 acre, self-propulsion and higher voltage become meaningfully important. Against the BLACK+DECKER 3-in-1 ($74.92), the Greenworks is a real lawn mower with a real 20-inch cutting deck versus a 12-inch trimming-focused tool. These don't compete — anyone with a genuine lawn needs the Greenworks; the BLACK+DECKER handles edging and small patches. The honest limitation: 40V lower power means the motor bogs down in thick or wet grass more readily than the 80V alternatives.

The Greenworks Pro 80V 21-Inch Self-Propelled ($479.99) offers the best value equation on this page: 80V high-torque brushless performance, self-propelled drive, 21-inch cutting deck, and a 5Ah battery included — all at $200+ less than the competing EGO 56V equivalent that comparably equipped buyers often consider. For budget-conscious homeowners with medium yards who want a genuine gas-replacement mower without the premium brand price, this is the strongest case. Against the base 80V Greenworks 21-Inch ($699.99), the Pro version saves $220. Battery size may vary between configurations — verify included battery specs before purchasing since bundle contents change seasonally. Against the Greenworks 40V Push Mower ($369.99), the Pro costs $110 more for self-propulsion and 80V power — worth it for slopes and yards over 1/4 acre. The honest limitations: Greenworks' charging time is slower than EGO on equivalent batteries, and the Greenworks ecosystem has fewer compatible tools than EGO's 56V or DeWalt's battery platforms. The 4-year warranty is shorter than EGO's 5-year coverage. For buyers who want to build a broader battery-tool ecosystem, EGO's wider lineup may justify a higher upfront investment. For buyers who just want a reliable mower, the Pro 80V delivers at a competitive price.

The BLACK+DECKER 3-in-1 Electric Lawn Mower ($74.92) is the budget outlier on this page — a 12-inch corded electric tool that mows, trims, and edges in the space where the Greenworks mowers all use cordless 40V or 80V batteries and proper 20–21-inch cutting decks. At $74.92, it's priced for a fundamentally different use case: small patchy areas, strip lawns along walkways, or urban yards too small for a full-size mower. The 3-in-1 versatility is the real selling point — buying a separate mower, edger, and trimmer at low quality would cost more than this single unit. For an apartment courtyard, a narrow strip between the sidewalk and the street, or a small backyard where a full mower would be overkill, the 3-in-1 handles the job at minimal cost and minimal storage footprint. The honest limitation is that the 12-inch cut width requires too many passes on any real lawn. A standard 1,000 square foot lawn takes 3–4 times as long to mow as it would with a 21-inch deck. The corded design also limits range to extension cord length, and extension cords become an obstacle in themselves on larger areas. Against the Greenworks 40V Push Mower ($369.99), there's simply no comparison for real lawn maintenance — the BLACK+DECKER is a specialty tool for minimal grass management, not a lawn mower substitute.
