Features of the Best Cordless Lawn Mowers

The best electric lawn mower reviews won’t just tell you the features of the lawn mowers themselves, but will also explain the features that are important in a cordless lawn mower, so you know what to be on the lookout for. There are a variety of considerations to keep in mind:

Drive

The batteries in cordless mowers are going to increase the weight of the mower. This means you may want to consider the self-propelled option. Self-propelling can be a fixed speed or variable. Some mowers will have a variable speed that will adjust automatically to match your walking pace.

Grass Discharge

Cordless mowers are not the right choice if you have exceptionally long or thick grace. They do not have the power that a gas mower does to get through this type of grass. If your grass is ideal for a battery-powered mower, you need to decide what will happen to the cut grass. Some mowers will require an additional accessory for mulching.

Keep in mind that mulching is going to require more power from the battery. This means your battery will run out faster, meaning you can cut less acreage.

Battery Size

The first feature you will notice is the different battery size options cordless mowers have. You will need to choose from 12, 24, or 36-volt battery packs. You may even find a 40-volt option for newer and high-end cordless mowers. A twelve-volt battery will run for thirty to forty-five minutes on average (with normal grass and landscape conditions). A twenty-four-volt battery will have a run time of forty-five to seventy-five minutes. You can run a thirty-six-volt battery for an hour and a half. You should be able to cut a third of an acre with a nineteen-inch, thirty-six-volt mower on a single charge.

Battery Type

For the most part, you will find lead-acid or lithium-ion batteries. Some mowers have Nickel-cadmium batteries. Sometimes the batteries will be fixed within the mower. Other units will have removable batteries. Whichever type of battery you choose is just a matter of preference and choice. If you intend to keep a spare battery for extended runtime, you’ll want the removable option.

Whichever battery you choose, you should get about five hundred charges before replacement is required. Calculate how large your yard is and how often you mow to determine your battery life in years.
