Sun Joe MJ401E Review

easy-to-use electric mower

If you are searching for a hard-working mower that is affordable, cuts taller grass features a grass collection bag and is low on maintenance, this one is for you.

Performance and Cut Quality

Sun Joe MJ401E is equipped with a robust 13-amp motor which produces power equivalent to a gas mower. When I first used this mower, I was quite impressed with its powerful performance and used it repeatedly in my yard. It is good on flat terrain but when I used it on uneven ground or sloppy region of my yard, it stumbled. It is not good on muddy areas also, I found it is because of smaller wheels. Coming to the cut quality, its steel blade in the 14” deck gives you an even and clean cut in every pass. The cut quality of this mower will never disappoint you. One thing I would like to point out is that grass cut by MJ401E is quite short but it is not a problem if you like short grass in your lawn. I always like it short.

Ease of Use

Using Sun Joe MJ401E is very easy, you just need to push a red coloured button to start this mower. To make it easier, the start mechanism is available at the handlebar. The safety lever is also present at the precise place. In most mowers safety lever is located far restricting you to properly use the mower but in Sun Joe MJ401E, you will find that safety lever is at a comfortable position, allowing you to operate the mower easily. There are three different settings to adjust the cut height (highest is 2.4”) but you have to do it manually. I miss a lever system for adjusting the cut height, though high-end models have it. Moreover, the user manual doesn’t have instructions to manually adjust the cut height. You have to turn the mower and spend a few minutes to adjust the height. Fortunately, it’s not something you have to do often.

Special Features

Sun Joe MJ401E has many special features. The first one is the noise level. It produces very less noise and people who previously used a gas mower will find a remarkable difference in the noise. Remember, it is not silent but you won’t find the need to use ear protection. It also prevents complaints from your neighbours. The second special feature is its weight, just 30 pounds. Old people or people having back problems never face difficulty in pushing this mower. Another special feature is the 14” cutting deck that makes it a perfect choice for smaller yards with compact spaces. The push-button start, position of the safety lever, and efficient bagging system are other special features MJ401E has.


It is designed intelligently. The company has included only the elements necessary for making it a great performer in a small yard/ lawn. After looking for the first time, you will find it cute. This is because of the green colour (towards the brighter side) and a plastic body. With plastic, you can’t expect it to be a rough and tough mower. If you want to use it for a long time, handle it with care. You can fold the handle of this more to store it comfortably even in compact places like the corner of your garage or on the tools shelf. Once you take it out of the box, it takes around 10 minutes to make it completely ready to mow.

Cost Effectiveness

This mower costs $139 and ships for free in the United States. This is the first cost-effective feature of Sun Joe MJ401E. It is difficult to find any lawn mower in $139 that runs on electricity and comes with a manufacturer’s 2-year full warranty. This mower does not require gas or oil which means fewer expenses. This feature will help you save money from the first day but you will see the results in the long run. A common scenario with people having bulky gas mowers is that they hire someone to mow their lawn. This is so lightweight that you won’t feel the need to hire someone to push your mower. Being low on maintenance is yet another feature that helps you save money.

Grass collection and discharge

I have seen that most electric mowers in this price range don’t emphasize on grass collection and discharge but this is an exception. To collect the grass clippings, this mower comes with a grass collection bag of capacity 10.6 gals. Remember this mower is for smaller lawns/yards, you have to repeatedly empty the grass collection bag when using Sun Joe MJ401E electric mower in larger fields. The grass clippings collected in the bag can be later used for composting. Another impressive feature is side-discharge which leaves all grass clippings in rows. The chute for side-discharge comes with this mower, so you don’t have to purchase it separately.


Since it is a corded electric mower, you have to always remain careful. But, being lightweight (only 30 pounds) and compact (48.4 x 40.6 x 40.6 inches) are the two factors which make this mower swiftly manoeuver around in any lawn/yard. Turning it during obstacles is super easy. Sometimes, people face a situation when lifting the mower is the only solution. If the mower is heavy, you face difficulty in lifting it but with Sun Joe MJ401E, lifting is never a problem. One thing I found negative is its wheels – both front and rear ones are of 6 inches. Yes, they are identical and of plastic. It means you will face difficulty to move this mower on uneven or rough surfaces. I also want to say that it will move efficiently on the flat, low cut surface but don’t expect it to be good on muddy areas.


I already mentioned above that it is a low-maintenance mower, don’t require heavy maintenance like a gas mower but this doesn’t mean you should avoid simple maintenance tasks also. If you want it to serve you for a long time, keep it clean and regularly remove dirt, grass, and other debris from it. The handle should always be kept dry and free from grease and oil. Since the blade is the most important part of a mower, it is important that you regularly check it and if found blunt or having minor wear, re-sharpen it. In case of major wear or bigger damage, replace it. Remember, always disconnect the power supply to your mower before checking its blade.
