Buying Guide: What to Consider When Choosing the Best Mulching Blades

If you’re looking to make your lawn-mowing job easier and more efficient, mulching blades are a great option. These blades finely chop grass clippings into tiny pieces and then deposit them back onto your lawn.

When choosing mulching blades for your mower, there are several things you will need to consider.

What material is the blade made from?

The material of the blade is an important factor when choosing mulching blades. Generally, you’ll want to look for blades that are made from either hardened steel or composite materials like polycarbonate.

Hardened steel blades tend to be more durable and hold their sharp edge longer than polycarbonate ones. However, polycarbonate blades are typically lighter and easier to handle.

The number of teeth on the blade

The performance of mulching blades largely depends on the number of teeth they have. Blades with more teeth can produce finer, more even cuts and disperse grass clippings better than those with fewer teeth. As a general rule, the more teeth your blade has, the better it will perform.

The thickness of the blade

The thickness of the blade is also important to consider. Thicker blades tend to hold their sharpness longer than thin blades and are more resistant to wear and tear. You’ll generally want blades at least 0.25 inches thick or thicker.

For example, the Oregon Gator Mulching Blades are 0.204 inches thick and feature a patented design that helps them stay sharp longer.

What size should the blade be?

The size of your mulching blade is important as it affects how well the blade will function in different types of grasses. For instance, a smaller blade may be better suited for cutting finer grasses, while a larger blade might be better for thicker, tougher grasses.

This would also depend on the size of your mower, as you don’t want to choose a blade that is too large for your machine. For the most efficient performance, look at your mower’s specs to determine what size blade it requires.

Is the blade easy to install?

You’ll also want to ensure that the mulching blades you are considering are easy to install. You don’t want a blade so complicated or time-consuming to install that you’ll spend hours trying to get it in place.

Look for blades that come with easy-to-follow instructions and have minimal parts or tools needed for installation. This way, you can easily swap out your old blade for the new one without hassle.

What design does the blade have?

The design of a mulching blade is also an important factor when choosing one. Some blades may feature grooves or channels that help direct clippings back to the lawn, while others may be more streamlined and uniform for a smoother cut. Knowing how you want your lawn to look will help you determine which type of blade is right for you.

For example, if you’re looking for a blade that will leave your lawn with a neat and even finish, then a blade with a more uniform design might be best. However, if you want clippings to be distributed back onto the lawn at an even rate, one with grooves or channels may be better suited for your needs.

Is the blade budget-friendly?

Finally, you’ll want to consider the price of the mulching blades when making your selection. While some blades can be costly, there is usually a wide range of prices available for different types of blades. You can find good-quality blades that fit within your budget if you take the time to shop around and compare prices.

Frequently Asked Questions

Are toothed mulching blades better?

Yes. Toothed mulching blades are designed to finely chop grass clippings, resulting in a finer and more natural appearance. This also creates a better mulch, which helps retain moisture in your soil and improve its fertility. Plus, the blades are designed to resist clumping, which can be a problem with some non-toothed mulching blades.

Are Gator blades better than mulching blades?

Gator blades are designed to cut grass with a sharp, serrated edge that cuts through thicker grasses with ease. This makes them ideal for tougher lawns and helps to prevent clumping. However, if you’re looking for a fine mulch that’s easy to spread over your soil, a mulching blade is probably the better choice.

Which is better high lift or mulching blades?

High-lift blades are better for cutting grass and lifting it into the air, while mulching blades are designed to chop grass clippings. If you’re looking for a smoother lawn surface, then high-lift blades may be more effective. However, if you want to create a finer mulch that will help retain moisture in the soil, then mulching blades are your best bet.

How sharp should mulching blades be?

Mulching blades should be kept sharp in order to effectively cut grass and create a fine mulch. Sharpening should be done on a regular basis, depending on how often you use your mower. The blades should be sharpened at least once per season and more often if you mow frequently.

How often should you replace mulching blades?

Mulching blades should be replaced at least once per season or more often if they become worn or damaged. Over time, the blades can become dull and may require more frequent replacement. It’s also a good idea to inspect your blades regularly for any signs of damage or wear. This will help keep your lawn in top condition and ensure your mulching blade works efficiently.


The best mulching blades are an essential tool to keep your lawn looking pristine and healthy. They help promote growth by returning vital nutrients to the soil, reducing weed growth, and preventing water loss in dry climates.
