Must-Know Tips for Choosing the Perfect Lawn Mower

If you’re in the market for a new lawn mower, it’s important to consider your specific needs and requirements before making a purchase. To help you make an informed decision, we’ve put together this Lawn Mower Buyers Guide to give you all the information you need to find the best lawn mower for you.

Lawn Size

The size of your lawn is an important factor to consider when choosing a lawn mower. If your yard is smaller than ½ acre, a push mower will do the job. However, if your yard is bigger than this, you’ll need a riding mower, which will allow you to cover more ground in less time and with less effort.

Terrain

The terrain of your yard is another important factor to consider when choosing a lawn mower. If your yard is mostly flat and clear, a standard push mower or reel mower will do the job. However, if your yard has hills, obstacles, or decorations, you may need a self-propelled mower or a zero-turn-radius mower, which can be more easily navigated around these challenges.

Power Supply

There are two main ways to power a lawn mower: gas and electricity. Gas mowers are more powerful and can last the full duration of your mowing session, but maintenance is more complicated, and these machines often start with a pull cord. Cordless electric mowers are quieter, cleaner, and easier to start, but they are not as powerful and can’t be run for as long per charge. Corded electric mowers give you unlimited run time but can be inconvenient due to the cord trailing behind.

Deck Size

Deck size refers to the width of the blades on your mower. The wider the deck, the bigger the blades. Decks range from 20” to 70” or larger, but most homeowners opt for a width of between 30” and 60”. A wider deck can cut larger paths on each pass but can make it harder to navigate around obstacles. A smaller deck is easier to maneuver but requires more passes on open areas.

Grass Clippings

Lawnmowers can deal with cutting grass in different ways. A side-discharge mower simply spits grass clippings back onto your lawn. A mower with a bagger collects clippings as you go, but you have to buy a bag separately and find a way to dispose of the clippings.

Attachments

If you choose a riding lawn mower, you may want one that’s compatible with various attachments, such as dump carts, rakes, and snow blowers. These attachments can greatly increase the utility of your machine.
