3 reasons not to buy

  • The grass collection bag on the Sun Joe MJ401E-PRO fills up very quickly, requiring frequent emptying. This can be inconvenient, especially for larger yards or overgrown lawns. (27 reviews)

    • “I filled the bag up in two rows and had to dump. I finally got sick of that and just used the side discharge.”

    • “My only issue with this lawn mower is the bag fills up so fast. I wish there was a larger collection bag.”

    • “Like many others have said, the bag is very small. I'm cutting grass that is about 10 in overgrown. So I understand why the bag gets so full. I cannot go literally more than 2 or 3 minutes without having to empty the bag. I'm estimating if you were cutting grass that only needed an inch off, you could go much longer without emptying the bag so often.”

    • “The trick is to empty out the grass collection box often as it fills up quickly.”

    • “Emptying the grass catcher bag was the part that slowed me the most.”

    • “Another thing that is important to note, the grass bag is rather small. It can fill up quickly and require emptying many times when mowing a whole lawn. Between this and having to constantly move/unsnag the extension cord, it added a lot to the time it took me to finish mowing my lawn.”

    • “the clippings bag needs to be pulled off and emptied pretty frequently — though I admit my grass had gotten pretty tall, so you may get more than a couple rows done before you have to empty it”

    • “The bag fills fast so keep that in mind. The mower stops mowing effectively when the bag fills, so you have to empty it often.”

    • “Other complaint... the basket really is quite small. My lawn is a small lawn; compared to your typical AZ homes, it is a small grass lawn. But I had to empty the basket at least several times before finishing the yard (disclaimer: I hadn't mowed my lawn for 6+ months, so there was a lot of grass).”

  • You have to be mindful of the extension cord while mowing, which can be quite annoying. Some users recommend creating a technique to manage it better. (24 reviews)

    • “The only con is you have to be mindful of the cord when mowing, but if you create a good technique. It becomes less of a nuisance.”

    • “I learned to walk in straight lines instead of walking in a square to keep from getting tangled up in the cord.”

    • “The first time will take longer, but once you figure out the right mowing pattern, you can mow without having to stop to move the electric cord out of the way.”

    • “I got in the habit of holding the extension cord with the power switch, which helped to keep it off the ground and reduced any tendency to pull against it.”

    • “If you've never used a corded mower, it's important to note that you will need to continuously move the cord in order to avoid running over and damaging the extension. The booklet that comes with the mower has a few tips on how to make maneuvering a bit easier, like mowing from right to left and putting the cord over your shoulder. Even still, in the long-run, it's a pain in the 'grass' to have to keep doing this. The cord also snags easily on virtually anything: trees, plants, those little solar-powered lights that rest on stakes, car tires, etc.”

    • “The only con is that you have to be aware of your cord. If you can successfully vacuum a room or paint a floor without painting yourself into a corner, you should have no problem with the cord.”

    • “No matter what you do while using an electric motor every now and then the cord will find a way to annoy you lol.”

    • “The only annoying thing is trying to keep the extension cord out of the way, but thats what you get with an electric mower.”

    • “The main thing to get used to is the cord, but I soon had a rhythm going -- on one turn I would toss the cord aside with my right hand while turning the mower with my left hand, and on the next turn I would kick it aside with my left leg while turning the mower with my right hand.”

    • “Mowing attached to a cord takes a little getting used to, but it's similar to vacuuming where you need to avoid running over the cord. Working away from the plug in point makes it so much easier.”

  • Adjusting the height of the mower involves lifting each wheel individually, which can be a hassle. The wheels are also noted as being made of hard plastic with poor traction. (14 reviews)

    • “Although you do have to lift the mower to adjust each individual wheel, it's not all that difficult.”

    • “Adjusting the wheel height requires emptying the catch basket and turning the mower over. The height adjustment plastic shows a little strain. I don't think this will tolerate lots of height adjustments.”

    • “There are 3 height adjustments which have to be done on the underside of the mower deck... The height adjustments are done by moving a springlike mechanism, not the easiest thing, but doable.”

    • “Setting the wheel height was a little bit tricky.”

    • “The height adjustment (which only goes to a too-low 3.5") on the individual wheels tends to jump out of the little notches with little disturbance. I've found one or more wheels suddenly at their lowest setting at least 4 times in the few weeks I've used the mower.”

    • “The wheels are too small, and are spring loaded. This makes them easy to adjust, but they need to be in the last notch. On the lowest notch, you'll be mowing roots. When mowing heavy grass, or bouncing on rough ground, the wheels can bounce out of their slot, and adjust themselves to a lower setting.”

    • “I had a problem that if I bumped something or pushed too hard the wheels would jump from the highest point setting to a lower setting. I fixed the problem using some tie wraps and holding the wheels on the highest position where I want it. The springs or the indentation to set the heigh are not that deep and the wheels will jump settings.”

Bottom Line

The Sun Joe MJ401E-PRO is a lightweight, easy-to-use electric lawn mower, perfect for those who want a hassle-free mowing experience. It's powerful enough to cut through tough and overgrown grass and features a convenient push-start button and lever controls. Assembly takes just about 10 minutes, and its compact size makes storage simple. However, the grass bag fills quickly, and managing the extension cord can be tricky. Adjustable wheels are a bit complicated, but overall, it’s a quieter, eco-friendly choice.
