Good lawn mower blades are characterized by two main things: Motor power and cutting ability. The lawnmower blade decides the length and quality of the trim you will get. 

One best part concerning the blade in a lawnmower is that it is capable of compensating the motor power of the machine, thanks to its sharp edge. It means that you can always have a quality cut with a particular length blade and sharpness even when your motor is not in a position of helping you increase the cutting speed. 

To ensure your lawnmower is working as required, it is advisable you invest in the best lawn mower blade in the market. That said, have a look at the excellent options we prepared for you through the help of gardening experts.

Best Lawn mower Blades - Buyer's Guide

number of blades

If you have a riding lawn mower, you’ll have to consider the total number of blades. However, some handheld mowers do require multiple blade settings, though more often than not, they just need one single blade. If you have a riding mower, it would be ideal to buy a lawnmower blade set that will match the width of your deck. Most self–propelled and push mowers only need one blade.

Material

The build material of the blade is not dependent on the model of the mower. The best choice is robust stainless steel. Lower metal can help you cut costs, but it is improbable that it will cut your grass.

Keep in mind that picking your lawnmower blade set is very important as it can really influence your life. You want to pick a blade that will actually do the job you’re seeking it to do. Remember to also look at the paint job on the blade, as this will help you tell if it will rust quickly.

length

There is no science to this; however, it is essential to note that longer does not mean better. The length decided on should fit within your lawnmower’s model. Most blades range between 16.75 inches and 22 inches. Most mowers are compatible with blades that are as long as 22 inches. However, remember it’s all based on your model. If the blade’s length is too short, it won’t cut as wide of an area, but at the same time, if it’s too wide, it won’t fit

deck size

The deck size is the final consideration you make when choosing lawn mower blades. Most push mowers have a deck size that ranges from 16 to 30 inches. Riding mowers have higher-sized decks, as well.

width

The typical width of most mower blades ranges between 2.25 and 3.5 inches. However, as we said earlier, it’s essential to pick a blade that is compatible with your machine. A blade that is too wide might not fit and can end up damaging the lawnmower. On the other hand, a shallow blade might not cut well. The best thing to do is to check your lawnmower’s manual for further advice on the required width.

Best Lawn mower Blades - FAQs

Which blade is known as the three-in-one lawnmower blade?

The mulching blades come with a versatile design and also known as the three-in-one mower blades. It can perform three specific jobs simultaneously with a single blade. Moreover, these blades are also compatible with applications like bag clipping, excellent mulching of grasses, and other processes, too.

How to sharpen a lawnmower blade?

It is essential to sharpen the blades at least once a year. You may damage the grass if you use the old blades – the lawn may become brown, and there can appear pests. Using a drill and sharpening stone is the best way to sharpen. Of course, you can use the rotary tool, bench grinder, angle grinder, but it seems to be too difficult. Also, you can ask professionals to sharpen your blades if you don’t want to do it yourself.

How do you determine the time to replace or sharpen the blades?

The best way to know that your blades need sharpening is to check the grass after mowing. If it doesn’t look smooth, it is a sign. Also, you may look at the blades themself, and if they have large chips or dents, you should sharpen them. But if you sharpen your blades twice a season, you won’t have any problem.

How to change lawn mower blades?

First of all, you should remove the old blades, so you will be able to set the new pair. You should lift the mower deck. However, some models don’t require this – you may just unplug the spark plug to reach the blades. Then you should use the additional instrument to remove the bolt. It usually doesn’t require much effort and is safe for you, but I recommend doing this when there is no gas in the mower.
