Performance & Usability

Setup couldn’t be easier: unfold and lock the handles, drop in the battery, and press the start button. No gas, no oil, no spark plugs. Just charge, click, and mow.

The mower is lightweight and maneuverable, making it a great choice for tight yards or anyone tired of pushing a heavy gas mower. The handle height adjusts to two positions, and the single-lever height control makes switching cut levels quick.

Runtime is solid — reviewers consistently got 40–45 minutes on a single charge, enough to cover a ¼-acre lawn. For larger yards, having a second battery is the smart play.

Real-World Use

• Mulching: Works great, chops grass fine and returns it to the lawn. Reviewers loved mulching for convenience and soil health.
• Bagging: Easy to attach/detach the catcher bag, though the mulch plug has no storage spot. Wet grass can clog the chute, so dry days are best.
• Cut Quality: Smooth and clean, even through tall and thick grass. Users compared its power to a gas mower — minus the noise and fumes.
• Portability: A top carry handle makes it easy to lift and store, and its smaller size means it doesn’t hog garage space.

At around $299, this mower is positioned well for homeowners who want the convenience of cordless without the premium price tag of self-propelled or higher-end models. Pair it with other Greenworks 40V tools like a trimmer or blower, and you’ve got a complete lawn care setup with shared batteries.

Compared to gas, you save on fuel and maintenance. No oil changes, no carburetors, no gas cans in the garage — just clean mowing.
