Item Specifics

The Sun Joe Electric Lawn Mower starts instantly just by pushing a button.  A safety feature switch was added so that it isn’t accidentally started.  The beauty of electric lawn mowers such as this one is that they are practically maintenance free.  There is no need to add gas, oil or perform tune-ups.   Running it is as simple of the push of a button and go.  A powerful 12-amp motor will cut a 14 inch wide path.  You can then tailor cut the height of the grass that you want with 3-position height control.  A detachable grass catcher feature was added for easy disposal of grass clippings.  This lawn mower weights only 29 pounds which makes transporting and putting it away a breeze.  The Sun Joe Electric Lawn Mower is ETL approved and comes with a 2 year warranty.

Make Sure to Use the Right Cord

A hot topic with this lawn mower is that people are using a lesser cord than they should.  This could cause the lawn mower to die out and not work properly.  Make sure to use the correct gauge cord.  The manual for this lawn mower states that for extension cords under 100 feet, to use a 14 gauge cord.  For lengths of 100 feet or more, a 12 gauge cord is required.  (Gauges work backwards, so a smaller gauge means it’s a thicker wire).   If you try to pull 12 amps of power (which is what this lawn mower runs on) with a 16 gauge 100 foot cord, the motor may burn out on you.

Easy to Assemble

The Sun Joe Electric Lawn Mower requires almost no assemblage.  All you will need to do when it arrives,  is to put on the bag and handle. Most customers said it took only around 10 minutes to have it  up and running.

To Use the Bag or Not to Use the Bag?

A common topic with Amazon feedbackers, was that the bag was too small to even bother with.  Most people started out with the bag and then quickly ditched the bag and let the grass fly.  If you do decide to use the bag, you will most likely be emptying it often.

Very Narrow Mower

This mower is fairly narrow.  This could be a selling point or a drawback depending on how much grass you have to mow and if you need to get in tight spaces with it.  It is going to cut only a 14 inch path.  If you are cutting a large yard, this basically means you will be needing to make more passes.  However, if you are needing to cut between buildings and tight garden spaces, then the Sun Joe MJ401E Electric Lawn Mower might be perfect for you.

Not for Thick and High Lawns

While a little electric lawn mower like the Sun Joe Electric Lawn Mower has some advantages, it does has a major drawback.  It is not going to be good for cutting through high grass nor will it be good for cutting through thick grass.  If you live in an area where the grass grows quickly and you don’t get to mow your grass frequently, you may want to reconsider getting this lawn mower.  However, if you only occasionally get behind on cutting your grass, you may be able to borrow or use a gas lawn mower to catch you up.  Then you can switch back to this lawn mower.
