3 reasons not to buy

  • The DeWalt DCMWSP255Y2 mower is noted to be heavy (approximately 75 pounds), which could make it less maneuverable for some users, particularly in tight spaces or for those who may have difficulty with a hand-push model. (3 reviews)

    • “Sturdy Heavy, about 75 pounds, but that's comparable to competitive RWD battery mowers.”

    • “It’s not that light but you can sit on it and make it move.”

    • “this thing is cumbersome and awkward to use”

    • “Manual lacks something; doesn't explain RWD operation well.”

    • “You also have to read the instructions closely on how to turn it on.”

    • “During assembly, it was a good thing it was pretty straight forward, but if you actually review instructions first, as I tend to do, you will be disappointed. The manual is small and printed on newspaper pulp, and very difficult if not impossible to read or discern what you're looking at. No text directions, but blurry illegible images.”

  • The chargers provided are criticized for being slow, charging only at 0.05 amps per hour, which means a full charge could take up to 24 hours for each battery. Upgrading to a faster charger is suggested by one customer. (3 reviews)

    • “The run time is fine but the weak chargers take over night to charge.”

Bottom Line

The DeWalt DCMWSP255Y2 is a durable, easy-to-start lawn mower with rear-wheel drive and Flexvolt batteries that work with other DeWalt tools. It cuts grass effectively, nearing gas mower power, and is made in the USA. Despite its solid build, it's heavy at 75 pounds, which might be tough for some to maneuver. It also has a tricky start-up and slow chargers, needing possibly a day to fully charge batteries.
