As mulching blades are more used by lawn mower users, you should know the proper use, pros, and cons of mulching blades too, so that you can use them wisely. To help you with that we are going to discuss the pros and cons of mulching blades in this article.

What are mulching blades?

Mulching blades are made with three layers of blades. As a “+” design, these blades feature two blades arranged perpendicularly to make mulching easier. Older mowers typically use “+” blades; they come with blades that produce a more effective mulch.

Mulching blades are mainly used to serve 3 kinds of purposes like- mulching, bagging, and discharging. This is why they are called the 3 in one blades. A lawn that receives mowing every three to four days is a good candidate for mulching blades. In order to mulch grass that has grown out of control, you will probably get a clog under your deck, and there will likely be grass piled up when you cut the lawn.

How does Mulching Blades function?

Mulching blades are curved in shape and the curves are to increase the edges while you mow your grass with a lawn mower or grass cutter. Because of the curved surface grass is cut more than once before getting reapplied in much smaller amounts. Mulling blades generate cutting action by utilizing curved edges and generally have a large cutting area that is exclusively used for cutting.

When using a mulching mower, the grass is directed to the blades by a stream of air, and the clippings are then hit multiple times by the blade before they fall to the ground. The clippings are not directed away from the mower as with most other mower blades. The purpose is to prevent clippings from ending up in drains. A lawn that is mowed every three or four days is the perfect substrate for mulching blades.

You will need to buy mulching blades that are medium in length as too small blades will cause a lot of pressure on the blades and also the mower.
