Buying Guide

Blade size:

Different lawn mowers have different sized-blades. The sizes can be somewhere between 10 to 25 inches.

Your mowing experience can vastly depend on the width your lawn mower’s blade covers. For medium to large-sized yards, you must choose wide blades. Otherwise, it will take much more time to cut the grasses and you will surely lose patience.

For compact yards, on the other hand, smaller blades are needed. Wide blades fill not give you precise cutting.

Cutting height:

Lawn mowers can feature just one cutting height or different heights. To choose the right one, you need to consider the size of your grasses and the look you want to give them.

If you like a bit longer grasses on your yard, go for the lawn mower than enables you to do the higher cutting and the opposite for keeping short grasses.

Power source:

The power source of your lawn mower can vary. There are different options to choose from- electric mowers or battery-powered ones.

If you want a low maintenance mower, it is easiest to use an electric one. You just need to plug the cord in and you can start mowing your lawn.

But if you find it troubling to drag the cords along, go for battery-powered mowers. There are two types of battery-powered ones- single-port and dual-port.

The single-port ones have only one battery that needs to be charged, sometimes even in between mowing sessions.

The dual-port, on the other hand, contains two batteries. So, you can charge one of them and use the other for mowing.


Lawn mowers can be made of steel or plastic and the blade is usually made of steel. The plastic ones are light and less durable; while the ones made of steel are comparatively heavy and durable.

The weight can vary depending on the material, and your operating will depend on its weight. So, you need to carefully check the product’s weight before buying.

Folding options:

Some lawn mowers are foldable, others are not. If you want to save space on your garage, it is better to get a foldable one.

There are also different types of fordable mowers, such as- handle folding, vertical folding. So before buying mowers, you must consider where you want to keep it. Depending on the space you can allot for the mower, choose the folding or non-folding one.
