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.
