What Size Lawn Mower Do I Need? Everything You Need To Know

4 minutes

There is no such thing as an ideal-sized lawn mower. It depends on your preferences, the size of your lawn, and sometimes even your budget. So, when it comes to “What size mower do I need,” the answer is, it depends.

Why Is The Size Of My Lawn Mower Important?

Always be careful when choosing the right size lawn mower.

Lawn mower size is more important when choosing a lawn mower than it first appears. It not only reduces spending but also reduces frustration. Here are some more reasons why lawn mower size is important.

The Size of the Yard

This is the most important factor you need to consider before buying you lawn mower.

If your lawn is a quarter acre or less (1,011.71 square meters), you should buy a walk-behind lawn mower. Any bigger than that and you’ll want to use a riding lawn mower. If your lawn is small, you can still get a riding lawn mower, but you’ll want to go with a smaller model.

In general, for smaller lawns, you’ll want a riding lawn mower with a cutting deck of 40 in (101.6 cm) or less. For bigger lawns, you’ll want a cutting deck that’s 42 in (106.68 cm) and up.

The Type Of Fuel Used

This is more for people who want to go easy on the environment. If your lawn is smaller, go with an electric lawn mower. They don’t require a lot of maintenance and you won’t have to buy any fuel.

For bigger yards, gas-powered lawn mowers are a better choice. They’re generally more powerful and have more size choices.

How Much Time You Have

Not everyone has a lot of time to cut the lawn. Not everyone wants to have that time. A smaller lawn mower will take longer to cut a lawn, no matter the size of the lawn.

On the other side of things, a bigger lawn mower will take less time to cut a lawn. So, how much time do you have, and how much are you willing to spend on cutting the lawn?

The Different Lawn Mower Types And Their Average Sizes

Now, let’s take a look at the different types of lawn mowers and what sizes they come in.

Sizes of Zero-Turn Lawn Mowers

A zero-turn lawn mower’s segments are very similar to those of most riding-type lawn mowers. Usually, they are about 4 feet (1.21 m) tall, 6 (1.83 m) or 7 (2.13 m) feet long, and 4 (1.22 m) feet wide.

The key distinction is that some have cutting decks larger than others. Notably, the trimming decks of these lawn mowers can go all the way up to 72 in (182.88 cm).

Sizes of Riding Lawn Mowers

The size of the cutting deck of a riding lawn mower normally lies between 36 in (91.44 cm) and 54 in (137.16 cm). This is true for lawn tractors too. In general, they are 6 feet (1.83 m) in length and up to 4 feet (1.21 m) in total height.

Sizes of Push And Self-Propelled Lawn Mowers

Push lawn mowers and self-propelled lawn mowers typically have cutting decks ranging from 21 in (55.88 cm) to 36 in (91.44 cm). These lawn mowers are around 3 feet (0.91 m) in height and 5 feet (1.52 m) long.

Electric lawn mowers tend to be within the same range, although usually, they’re on the smaller end of that range.

Size of Reel Lawn Mowers

A reel lawn mower‘s width is typically 13 in (33.02 cm). They are around 3 feet (0.91 m) tall and 2 feet (0.61 m) long.

Keep in mind that reel lawn mowers are only going to be good for very small lawns. Anything too large and you’ll be exhausted and frustrated.

I bought a 20″ Bolen push mower 2 years ago late in the year and put no more than 3 hours on it. I ran all the fuel out the last use so I could store it. I could not get it to start the following spring and oddly enough my next door neighbor has the same problem with his. What a piece of garbage. I borrowed a mower last year as my dad had an extra, but I will have to purchase a new one this year. I have never had a mower especially with a Briggs engine that is that kind of garbage.
