Best Cordless Lawnmower Buying Guide

Electric lawnmowers can be big ticket purchases, which is why it is recommended that you consider the factors mentioned below before making an investment.

Cordless vs corded – All the models mentioned on this list are powered by rechargeable batteries, so there are no wires hanging around as you mow. However, there are also models that can be plugged into an electric outlet available in the market, which means that you not only have to risk tripping over the power cord, but will also need one or more extension cords to extend the range.

Cutting width/deck size – the deck size is basically the width of the mower’s cutting swath, where the wider the deck size, the less you will have to pass across the lawn area.  If you have a smaller lawn with lots of tight turns, you might be better off with a smaller deck to make maneuvering easier. On the other hand, for larger lawns, try to get the largest cutting width available to make quicker work of cutting your lawn.

Grass management – this commonly includes three options to choose from –shoot the grass clippings to the side, mulch the clippings back into your lawn, or collect the clippings in an integrated bag for mulching and disposal.  If you mow your lawn regularly and don’t let it grow to tall, we suggest you use the mulching option as this will return the cut grass to the lawn and add nutrients naturally.

Height adjustment – this is important because lawn care experts recommend not cutting your grass less than 30 percent of its overall height. Grass tends to get weaker when cut below this height, hence may be less resilient to dry weather, and susceptible to disease. The best cordless electric lawnmowers allow you to adjust the height between several positions with a single onsite lever.

Starting mechanism – the best electric lawnmowers are easy to start with a dedicated push start button, so you don’t have to apply any extra muscle struggling with a starter cord generally seen with gasoline lawnmowers.

Push vs. self-propelled – self-propelled lawnmowers just as the name would suggest propel themselves forward automatically, and are generally easier to operate. This is a great mechanism to have if you buy a heavy mower or if you have a large size lawn to cut. But if you have a small to medium size lawn, a push type electric lawnmower is an ideal choice.  A push mower will also give you more exercise if that is a consideration for you.

Brushless Motor – Battery operated lawn mowers already require far less maintenance than their gas powered counterparts but choosing an electric lawn mower that features a brushless motor is an ideal choice.  Not only does a brushless motor consume less power, it provides greater power and torque.  Additionally, there are no brushes to wear out over time, meaning almost zero maintenance required other than normal cleaning and blade sharpening.

Wondering exactly what a brushless motor is and how it can benefit you?  Check out this video for a complete explanation.

Final Thoughts

The best lawnmowers not only cut the grass well, but also save you a significant amount of cash spent on gasoline and maintenance each year. Plus, they are easy and cost efficient to maintain, are virtually silent, and perhaps most importantly do not emit any dangerous fumes into the air.

The five best cordless lawnmowers mentioned on this list come with all the essential features for smooth performance such as push button start, height adjustment via a lever, and are powered by long lasting rechargeable batteries, so you really can’t go wrong with any of them.

Remember to choose a lawn mower based on our simple buying guide above for your particular needs and you should have a quiet, efficient lawn mower for years to come that is not only easy to use but is better for the environment as well.
