9 Best Mulching Blades in 2018 to Give Your Mower Second Life (Reviewed)

What Are Mulching Blades?

Many people want to have an ideal lawn, but only some of them understand that it is a hard work. It is a mistaken opinion that any mower will do its work perfectly. If you wish to have a perfectly cut grass, then choose a machine with the best mulching blades.

What is a mulching blade? It is a knife used not only to cut, but shred grass into tiny pieces that will be naturally recycled. Traditional machines for cutting have bags for collecting clippings, mulchers disperse wastes of grass and in such a way, make your lawn healthier. Ideally chopped grass returns to the soil and nourishes it, making more fertile.

There are many benefits of using mulching lawn mower blades. Just look at some of them:

  • There is no need to clean the lawn from grass clippings.
  • Small pieces of grass are fast decomposed and provide necessary nutrients to the soil.
  • Healthier lawn.
  • Best lawn mower mulching blades guarantee perfect cutting.
  • Best mulching blades are usually made of high-quality materials and will last longer than standard knifes.

Two Main Types of Lawn Mower Blades

Generally, there are two types of mower cutters- standard and mulching. If you don’t know which kind of knife to choose, let’s know about their differences. So, mulching blades vs regular blades, what type do you need?

Standard

Standard knives are also known as two-in-one, are made to cut the lawn and then bag or discharge clippings. They have an aerodynamic and straight design. Owners of yards usually choose such kind of knives when they don’t wish to leave grass clippings on the lawn and wish it to look ideally neat. Standard cutters are good choice for territories that don’t require frequent mowing.

Mulching Blades

They are also called three-in-one knives. Mulching cutters are used to shred, discharge or bag clippings of grass. They are characterized by increased edge of cutting and some curves. Using such type of knives, grass will be cut several times before transforming into small pieces that will fall on the lawn. Shredding is a great eco-friendly way to use lawn clippings. Tiny wastes of grass act like soil conditioner and make it more fertile for various plants, bushes and trees.

Mulching mower blades are ideal for areas that need frequent cutting. Note that there are two kinds of mulching cutters: gator mulching blades and standard. Gator ones have sharp angled teeth, like an alligator and are popular for all year round grass cutting.
