Bottom Line

The Greenworks 25302 exceeded the expectations of many users. Most purchasers remarked that it has excellent cutting power and sometimes did better than their older gas-powered mower. Consumers also liked that it came with a fast-charging 4AH battery plus a back-up 2AH battery giving it good run time without the need to buy a spare. Not to mention that batteries are also compatible with other Greenworks 40V tools. However, despite the very good reviews, some owners thought that the plastic build and its ability to suction debris needed improvement. But all in all, it was regarded by a lot of buyers as a reliable, easy to use mower, and a must if you already own other 40V Greenworks tools.
