TLDR Review: Greenworks 80V Brushless Lawn Mower

By ShopSavvy Team

Published: February 24th, 2026

Pros

•Powerful brushless motor delivers performance comparable to a 160cc gas engine without the hassle of fumes or gas maintenance.
•Lightweight and easy to push, making mowing less tiring, especially on flat yards.
•Comes with two 2.0Ah batteries and a rapid 3inute charger, enabling near-continuous mowing by swapping batteries.
•Batteries are compatible with over 20 other Greenworks 80V tools, adding versatility and cost savings.
•Large 10" rear wheels and steel deck provide durability and ease of movement over uneven terrain.
•Smart Cut loaensing technology adjusts motor speed based on grass thickness for efficiency and battery conservation.
•Quiet operation reduces noise substantially compared to gas mowers.
•Simple and fast blade replacement with no professional help needed.
•Easy singlever all-wheel height adjustment offers convenient cutting height changes.
•Effective on large properties (up to about an acre) and can handle tall, thick, or slightly wet grass with some care.

Cons

•This model is a push mower, not selropelled, which can make mowing larger or uneven lawns more physically demanding.
•Battery life can be shorter than advertised under heavy or wet grass conditions, sometimes less than 30 minutes per battery.
•Minor ergonomic annoyances include handle knobs occasionally loosening and a bag that can be tricky to empty cleanly.
•The bagger, while effective, becomes heavy and harder to maneuver when full.
•Some users note that the mower occasionally leaves clumps of uncut grass at higher motor speeds, requiring manual spot trimming.
•Swapping batteries is essential due to runtime limits, which might necessitate investing in additional batteries for larger yards.
•Close trimming near vertical edges can be challenging—wheel alignment doesn’t completely match blade width for neat edges.
•The mower may be slower with very tall, thick grass and requires a more patient approach compared to gas mowers.
•With only 2.0Ah batteries included, runtime may be limited unless upgraded to higher capacity batteries.

Bottom Line

The Greenworks 80V 21" Brushless Cordless Lawn Mower is a strong, eco-friendly alternative to gas mowers that combines cordless convenience, powerful cutting performance, and compatibility with a broad 80V tool ecosystem. Its lightweight design and quiet operation make yard work easier, though as a push mower, it may not be ideal for users seeking less physical effort or faster mowing on large or uneven terrain. Battery runtime is sufficient for average-size yards but might require extra batteries for nonstop work on bigger properties or thick grass. If you want the same power with easier operation, consider looking for the *self-propelled* version of this mower. Overall, it's a highly recommended choice for those who prioritize low maintenance, environmentally friendly operation, and tool compatibility.
