Sun Joe MJ401C-XR Battery Lawn Mower Review

Sun Joe MJ401C-XR Battery Lawn Mower Review


The name “pretty” lawnmower may sound a little strange, but the Sun Joe MJ401C-XR battery-electric lawnmower has a pull factor. Maybe it’s because of the space age roundness or that it looks a bit like a toy. None of this matter as the machine works great in small lawn areas, cutting a 14-inch wide strip. It is powered by a 28V Li-ion battery with a battery life of 20 to 25 minutes. The mowers can manually adjust the cutting height in three different positions from 1.2 to 2.5 inches.

This ETL approved lawnmower features a removable 10.6-gallon grass catcher for easy disposal and a two-year warranty. It is also possible to purchase the version with side discharge, sold separately.

Easy to Use

The Sun Joe MJ401C is a cordless type which in itself, offers a convenience that string knives do not have. You don’t have to worry if the cord is long enough to cover the entire lawn or not plugged into an outlet. Cables can also cause accidental slippage when cutting. Hence, it is a safety measure to keep them out.

I also like that the battery-powered engine is so quiet that it doesn’t feel too heavy on the ears unless the car is accelerating. Also, it is easy to insert because it is light and compact. The design is similar to a toy car with wheels, making it almost fun to use.

The blades also make them easier to use. It handles edges very well, which you won’t find on mowers with a bulky front. I haven’t pushed and rotated this cutter as I cut with it every time, and it doesn’t seem like a tedious job.

I am delighted with how easy this product is, easy to use, and easy to use at the touch of a button without dealing with fatigue or sore hands after a good cutting session.


Sun Joe has durable all-terrain wheels and a convenient electric cruise controller that automatically kicks in automatically when the grass gets thicker and thicker. This is a good thing, considering that San Jo can sometimes control this type of weed. This is an accurate feature that you can hear clearly when the car switches between two driving speeds. You can set the maximum mowing height for fast-growing thick grass. That way, you’ll have fewer stops to empty your pocket.

The Sun Joe is very easy to maneuver and maneuver thanks to its lightweight, and the durable wheels rotate smoothly on uneven surfaces. It may not be a robust and functional machine, but most of the time, the Sun Joe generally provides an excellent looking lawn, as long as it is not too long or wet.

One of the disadvantages of this cutter is that the battery is connected to the machine. It means that instead of simply removing the battery and recharging it yourself, you must connect the entire lawnmower to an electrical outlet. Most would probably agree that a removable battery makes charging the Sun Joe easier.

Also, keep in mind that you cannot buy a replacement battery with this lawnmower if you want to cut a bigger garden. You only have one battery, and it lasts 20 to 25 minutes.


The Sun Joe MJ401C-XR requires less maintenance. Since it runs on battery and runs on battery, you can forget about adding oil or gas or whether the engine’s oil/air mixture is right. There is no need to schedule adjustments regularly. No maintenance is required for electric models.

What you need to know is to take good care of the battery so that its life is longer than the manufacturer’s recommendations. Typically, lithium-ion batteries can be charged for around 1000 cycles before having to worry about replacing them. However, if you don’t abuse the battery, you can use it longer. Remember to keep your device with a blank boot.

The blades would stay sharp if not overused. You can sharpen it once a year for a good cut. Also, clean the mower’s underside after each use to prevent it from building up in this area. It will affect the quality of the cut. You can also replace the blade if you find it stops working as before.

Safety Features

Since this lawnmower looks like a tempting toy for children, it is good that it comes with a switch that needs to be connected to operate the lawnmower. Sun Joe also has a lock button that the operator must press to start the cutter.

Special Features

This lawnmower is best suited for small lawns and can be quickly started at a button’s press. With a convenient LED battery level indicator, the operator can monitor the battery charge. The removable key prevents children from accidentally turning on this cutter like a toy, and the 28-volt 5 Ah lithium-ion battery offers decent power and performance.


The total weight of this device is only 23.1 pounds. It is ultra-light and compact. Besides, it is environmentally friendly and easy to use, which, in my opinion, are two important parameters when choosing the right cutter.

The mower can be adjusted to three height levels. It is ideal to adapt to your size. It is an ergonomic feature that I find very useful because I am short and need a sideboard that can be adjusted to fit and is comfortable for my body to cut.

The blade is initially sharp and resistant to corrosion; the blade is made of high-quality steel to prevent water from damaging its surface. The blade is 35 centimeters long enough to cover a wide cutting path.

This model has a safety key that must be inserted when using the lawn. This is an essential function, ideal for people with children, as it can protect against accidental starts.



If you’re looking for a cordless electric lawn mower that won’t leave a light in your wallet, opt for the Sun Joe MJ401C-XR. This renowned cutter is economical and efficient. You get a 16-inch cutting platform that allows you to cut more than small areas.

The machine is equipped with an automatic acceleration function that increases the driveshaft’s speed to the blades when it is detected that it is cutting hard grass. This car is the lightest in this round, weighing just over 37 pounds. The result is excellent machine control, and you can easily maneuver the cutter in tight spaces.

How long does the battery last?

The Sun Joe MJ401C-XR battery can power the engine for up to 25 minutes before another charge cycle is needed.

Can it mulch?

Unfortunately, this machine does not have a mulch function. The MJ401C-XR is a bag cutter that does not even have a side discharge function.

Who should buy the Sun Joe MJ401C-XR?

Should you buy this model?

Lawnmowers, especially battery-powered models, should be the size of the lawn. For a smaller lawn, this is a smart and impressive choice. It is compact and easy to maneuver. The battery doesn’t last for extensive gardens, but it keeps small gardens clean and tidy with minimal effort.
