What to Look for Before Buying Mulching Blades for Zero Turn Mowers?

zero turn mulching blades

As mulching is a different operation from bagging, and mulching blades come in different types, you need to choose the right blade for the job. Picking an effective blade or mulching set will make your job easier. Check the following.

Blade Type

Mulching blades come in two different types. The first one is a standard mulching blade which can be used with a variety of mowers. But the second type is called gator blades or 3-in-1 blades. These blades have serrated edges with angled teeth.

Though standard blades are also efficient in mulching, serrated blades will cut grass into smaller clippings. This improves the overall performance of the mowers in mulching and leaves less hassle for you.

Blade Size

This depends on the size of your mowers. Blades come in certain lengths and widths to fit different models. You will commonly see 18.5 and 21 inches long blades. Most blades are 2.5-3 inches wide and have a thickness of about 0.2 inches.

The thicker the blade, the better will be the durability. But it can reduce the sharpness of the blade. So, you should go for an optimum size that will give you maximum performance.

Teeth Type

Some serrated blades have pointed tip teeth, while others have flat tip teeth. Though pointed teeth blades seem to be more efficient, flat teeth blades will turn grass into much smaller clippings due to the reduced gaps between teeth.

Also, count the number of teeth on each side of the blade. The more the teeth, the finer the clippings will be.


Most mulching blades come as replacement parts to turn your regular lawn mowers into mulching mowers. As these blades need to replace the OEM part, they need to fit into the machine perfectly for smooth operation.

So, these blades contain an OEM number which you should check before buying. Check the owner’s manual of your mower to find the OEM number of the blade. Get a matching replacement blade for mulching so that it fits correctly.


Though gator blades are costlier than standard blades, they will perform a lot better. So, it will be better to invest in a set of gator mulching blades. If budget is an issue, you can choose an affordable set instead of those pricey blades. This can help keep your lawn in a better condition.
