What You Need To Know About Mulching Blades

A mulching blade is an ideal tool to have with your mower because it can offer many uses and can handle different applications or tasks. These types of blades along with curved blades provide additional cutting options to your lawn for more accurate and efficient lawn work.

A good combination of mulching blade and lawn mower provides even and more desirable cuts on grass. Modern mowers that use mulching blades are designed with a pair of perpendicular blades that rotate at the same time for better and more efficient cutting performance.

With a good length of mulching blade, not only can you make accurate cuts but can also do the job quickly as it covers a large area of grass.

Proper Use

To be able to make accurate and efficient cuts using the mower with mulching blades, it is better to start from the top corner of the lawn them move downwards to another corner. As soon as you reach the other corner, move towards cutting another one as moving in a circular motion.

Doing so, will help you sort out the cuttings more efficiently as they are being expelled or thrown on one side of the mower depending on your mower’s specifications. Proceed with the circular mowing motion until the center of the lawn is finished.

Mulching blades are designed for specific heights of grass. Before you set up your mulching blade on your mower, be sure that you’re dealing with the right height of grass.

For example, a mulching grass designed for 3 inch cuts on the grass can cut grasses that grow more than that – say 4 or 5 inches. Anything less would make the mulching blade inefficient.

Considerations To Make When Purchasing A Mulching Blade

Before you jump into purchasing any mulching blade for your mower, you may want to take a look at these considerations first. These considerations will help you pick the right mulching blade for your needs and one that can match your mowers blade requirements.

Also with these considerations, you’ll be able to have a better picture of your ideal mulching blade and as well as a better insight of other alternatives.

1. Teeth


Currently, there are two types of mulching blade teeth that you can consider – one is the standard mulching blade and the other is the gator mulching blade.

There is not much difference among these two types aside from the shape and the angle of curvature on their cutting edge. While the standard mulching blade features the regular teeth which are the same as the saw, the gator blades come with angled teeth for deeper and tougher cuts on grass.

Generally, a standard mulching blade is ideal if you’re dealing with thin types of grass while the gator blade would be recommended if you’re looking to make tough cuts on grass, weeds or small bushes.

2. Shape
