Full review
Longer notes from the same comments we summarized above.
What people reported
Many owners praise the Greenworks Pro 80V 21 in. mower for its power, stating it is "very powerful and capable" and can handle taller grass, especially when the cutting deck is raised. Users often find it easy to push, with some noting they "never even thought once that I wished it were self propelled." The quiet operation and reduced maintenance compared to gas mowers are also significant advantages that lead some owners to say they "can’t imagine going back to gas." The mower's mulching function generally performs well. Some users reported their mower has been reliable for "year two with no problems."
Problems people mention
A recurring issue for Greenworks Pro 80V owners involves the batteries failing to charge. Many described a common problem where the charger's red light flashes, indicating a fault. While several users found a "trick" involving repeatedly unplugging and re-plugging the charger, or even jumping the battery with another, to get it to charge, this suggests a systemic issue. One owner detailed a battery repair, finding five dead cells, but concluded it was not cost-effective and complicated due to tightly clamped cells.
Beyond battery issues, some users report inconsistent cutting performance, describing their lawn as having a "bad haircut" with some blades cut and others sticking up or lying flat. This is particularly noted on less dense or higher moisture grass, and some attribute it to less lifting force compared to gas mowers. There are also concerns about the durability of plastic control levers, fearing they could "sagged and snap off" when mowing under branches.
Perhaps the most significant negative feedback centers on Greenworks' customer service and overall product quality. One owner described a Greenworks Pro 80V trimmer (part of the same battery platform) burning up after only two uses, receiving a "cheap ass head" on the replacement, which was then impossible to change due to loctite and later rivets. Multiple comments stated, "their customer service is bad," with one user detailing issues with broken refurbished items and no-return policies.
Where owners disagree
Owners generally agree on the mower's power and ease of pushing. However, opinions vary on the cutting quality. While many are satisfied, some perfectionists feel the cut isn't "perfect" compared to high-end gas mowers, especially in specific grass conditions. The general sentiment about switching from gas to electric is overwhelmingly positive, despite the mentioned drawbacks.
Who it's for
The Greenworks Pro 80V 21 in. mower is for homeowners seeking a powerful, easy-to-use, and quiet battery-powered alternative to a gas mower. It suits those who prioritize ease of maintenance and environmental benefits. Potential buyers should be aware of the reported battery charging quirks and potential inconsistencies in cut quality, and factor in the widely reported challenges with Greenworks customer support.
