3 reasons not to buy

  • Some people think the handle is shaky or not strong enough. One user had to turn a nut around for a tighter fit and use zip ties to make it more stable. This suggests that the handlebars might not hold up well to being folded and unfolded over time. (12 reviews)

    • “the entire handle bar assembly was very weak and wobbly”

    • “Only noticeable issue was handle attach hardware. Knobnuts are quite small and make tightening handle sufficiently, quite difficult. Also, upper quicklatching type bolts are short. In order to get threads to engage upper and lower portion of handle, a firm grip or clamps are needed to tightly match handle together to get knobnuts to thread correctly.”

    • “The plastic locking handle and plastic hut/hubs/knobs arrived stripped/broken so the handle would not stay open and would fold into the storage position at the lighted touch.”

    • “The instruction didn't mention how exactly to attach the handle. I put the handle on and started spinning the little piece in place to tighten the handle. It kept spinning, even though it looked right. I eventually figured that the spinning was to keep you from over tightening it. The plastic around it broke off on both sides and it became wobbly after a few uses.”

    • “The folding handle will give you some grief, as the retaining mechanism isn't very tight, and the handle will try and fold on you during use.”

    • “But all nuts and knobs need to be tightened before use. I lost two nuts in my lawn. They are nowhere to be found and the handle is loose.”

    • “Happy with it except for one of the handle adjusters coming loose while mowing and getting lost so I had to use a bolt and nut instead.”

    • “one of the screws that keep handle from folding is stripped and will not tighten”

    • “The only problem is that the clamps that secure the handle in the straight position do not tighten fully, so when the clamp is set the handle will still fold when any significant pressure is put on it”

    • “Am disappointed to find that the metal arm has so easily twisted and broken.”

  • Although the mower is described as heavy duty, its weight can be a problem for some users, particularly because it is not self-propelled. (9 reviews)

    • “this is a heavy duty metal deck mower that is not self propelled, if your thinking it's a lite easy to push around electric, look elsewhere it's built like a tank”

    • “being non-self propelled means you get an extra good work out”

    • “It’s not lightweight”

    • “While it is very easy to push, it's a little too heavy for me to lift.”

    • “This greenworks one was also significantly heavier than the Black & Decker, which I didn't mind for the flat part of my lawn, but it was a little troublesome on the hills.”

    • “Shocked by how heavy it is.”

    • “Not a lite wait by any means weighing in at 55lb”

    • “The mower is a bit heavy, as compared to a 19" one I had previously”

    • “The wheels are large, but really hard to push, even for me, so she had no chance.”

  • Many reviews say that the bag for grass clippings is too small, so you have to empty it a lot, especially when mowing larger areas. One person also said that the bag's design can cause clippings to jam, and you have to take them out manually. (7 reviews)

    • “The clippings bag is too small. I'm used to larger bags that require emptying less often. Also, the bag does taper toward the opening, which creates a jam point when emptying.”

    • “The grass catcher is a little small. I have to empty it three or four times while cutting my yard.”

    • “Although I did have to empty the bag more frequently, of course.”

    • “The bag on this one also seemed rather small, but I can't really tell how well it fills because the grass doesn't really make it back there.”

    • “The only bothersome thing is that the grass doesn’t get thrown to the back of the bag so sometimes I have to stop and shove it back to get the bag full.”

    • “Also, the catch bag was not very good at keeping the grass INSIDE the bag. after about 5 mins of use the grass was literally being blown through the large holes in the bag.”

    • “The only thing i don’t like is the grass bag. As my dad is mowing the dries grass seems to go through the bag causing dust as he is walking the mower”
