Even when I started my journey, I had the question in my mind: what size lawn mower do I need?

Don’t just hesitate to scroll down your mouse if you want to come out with the best lawn mower size for your lawn.

How to Measure Lawn Mower Size

To measure the size of a lawnmower is pretty easy if you know how to measure it. Well, the size of a mower basically depends on the size of your lawn. The larger your lawn is, the bigger lawnmower you need. On the flip side, if you possess a small yard or lawn, then you don’t have to invest a big amount of money in buying a mower.

You might have come to the point that without the size of your yard, you cannot decide over a lawnmower. But we don’t know what is the size of your lawn. That is why we have decided to suggest different sizes of mower for different sizes of lawns and yards. So, you are recommended to skip to the heading that will fit your lawn size.

If you have a lawn having ½ acre of area, then you don’t have to think bigger. As it is a small lawn, you can choose a small size of lawnmowers, which will provide you with the best performance. In this case, you have to take two factors into consideration. One is the cutting width and the other is the horsepower of the engine.

Based on our experience, we recommend you to buy a mower having at least a 14HP engine. If you go for greater than 14HP, it will do good. But it is totally unnecessary to spend your money on a stronger engine as your lawn is a small one. In the case of cutting width, we recommend you to go for up to 42”.

Well, if you have lawn larger than ½ acre, then the size of your lawn might be 1 acre. In this case, you have to choose a mower that is stronger than the previous size. You may think that the difference between ½ acre and 1 acre is not much. But when you think of buying a lawnmower, the difference plays a vital role.

However, you have to choose a mower having an engine of 15HP. Though there are many experts who suggest 14HP to 16HP for such a lawn, we highly recommend you to go for 15HP. From our experience, we have seen that an engine having this size works greater. When you think of the cutting width, you are recommended to choose up to 44”.

Those who have lawns having approximately 2 acres must require a robust lawnmower. You can, however, do your job with a lawnmower having the configuration mentioned above. But it would never be a wise decision. Rather, you should pick a mower having a higher configuration than the previous one.

To be specific, we recommend you to buy a mower that has up to 46” of cutting width. And the power of the mower must be approximately 16HP if you want to enjoy the best performance from the machine. However, you will find a good number of riding lawnmowers in the market if you search for this configuration. Just grab one of them and stay relaxed!

If you are one of those who possess large lawnmowers, then the configurations discussed above will bring you no benefit. They are meant for comparatively small lawns. At this point, you might wonder what the perfect configuration is for you.

In this case, you should buy a mower that has at least 18HP and at best 24HP. That said, you can go for 18HP if your lawn is about 3 acres. And if it is larger than the size, then you have to increase the engine power according to your lawn area. When it comes to choosing the deck, we recommend you to go for 46” to 54”.

Other Factors to Consider While Choosing a Lawnmower

Capabilities of the Mower

You may require a mower for either mulching or bragging. If you do one of the jobs, then you have to make sure the right type of mower. But if you want a mower for both of the jobs. Then you must be a little bit careful while buying a lawnmower. It is because a few of the mowers are designed for both purposes.

If you don’t know what mulching and bragging are, then you must learn about them first. Mulching is meant for cutting small grasses into tiny pieces, while bragging is meant for cutting comparatively long grasses. So, decide over the size of your grasses before you choose a type of mower.
