Lawns and yards are some of the highlights in many homes. In fact, in most cases this is the first thing that attracts the attention of people who visit your home. And therefore, it is important to ensure that you provide you with maximum care in order to maintain its aesthetic appeal. To do this, you need a lawn mower with a high-quality blade.

Lawn mower blades are what will actually do the mowing, so it’s important to choose the one that not only matches your specific lawn mower, but also meets the individual requirements of your yard or lawn. This article looks at some of the best mower blades on the market to help you find something that will give you maximum lawn care.

How Do You Know if A Blade Fits Your Model of Lawn Mower?

The holes on the mower that attaches the blade, and the dimensions of the blade, as well as the serial number of the blade, are important factors to consider when replacing the mower blades. The following measurements should show if the knife is suitable for the mower.

Lawn Mower Measurements:

  • Number of Holes: A blade usually has one to three holes for attaching to a lawn mower. The number of holes along with the shape and size should be the same as the fittings of the lawn mower.
  • Hole shapes: As a rule, the central holes are in the shape of a 5-point star with round holes on the side. Some of the holes in the blade may be rectangular, or the star may have seven points instead of five.
  • Hole sizes. In addition to the shape of the holes, it is important to measure the size of the holes. Two measurements must be made, the internal size and the external size of the whole. Interchangeable blades include washers to adapt all shapes and sizes to the various mower blades.
  • Distances between external holes. An important measurement is the distance between the shelves. These measurements are taken from the center of the two outer side openings.

Overall Blade Measurements:

  • Length: Blades that are too long are not suitable for a lawn mower, and blades that are too short do not cut as efficiently.
  • Width: ¼ to 4 ¼ inches. Blade length has a greater effect on how the blade fits than width. However, for optimal performance, choose a replacement blade kit with the same width as the original blade.
  • Thickness: 1/10 to 1/3 inch

When you have these numbers, you are ready to start looking for a replacement. Here are some choices for some great aftermarket lawn mower blades that you can buy so your old mower mows like new!

Homeowners who like to keep green and healthy lawns will want the right knives for their lawn mowers. And the encouraging news is that there are more than enough options available on the market. But without the right information about leading brands, the choice will never be easy.

Our reviews, listed above 10 of the best on the market, will show you the features that make each one a good choice and why it will work well for your lawn mower. Given these reviews, you will get the correct blade replacement.


What’s the difference between Standard Mower Blades and Mulching Blades?

Standard knives are also called 2-in-1 knives or regular knives and are usually used on lawn mowers without mulching for lateral shipment or bagging. When adding the mulching kit to the mower, you must replace the standard knives with the mulching knives.

These standard straight knives, designed for a cleaner cut with greater airflow, push the cut grass back onto the lawn or into a bag attached to the mower.

Three-in-one blades or mulching blades are blades that cut and mulch grass. These blades chop the sliced ​​pieces into smaller pieces that can be packed in bags or left on the lawn as a natural fertilizer. The clippings are small enough to let air, water, and nutrients pass through.


How do High Lift, Medium Lift, and Low Lift Blades Work?

Raising the blade draws grass into the deck and exits the side unloading or bags. The lift also induces circulation suction for mulching. The rise is measured by the degree of the inverted edge of the blade.

Side unloading lawn mowers will use low lift knives and cutting inches or less. Low suction power keeps grass mowing low, so that it can be swept through lateral discharge. Low-lift blades work well when cutting short or dry grass and on sandy ground, preventing unnecessary suction of sand into the floor.

High lift lawn mower blades provide higher fan suction power under the mower, which pushes cut grass into the bag. Because of the high suction power, high lift blades require more mower engine power than other blades. A more vertical blade design with a cutting edge of 1 to 1 3/16 inches effectively cuts tall and compact grass.

Standard blades are typically mid-rise blades with a cutting edge between between 15/16 inches that rotate horizontally. These blades require less power than high lift blades. However, mulching blades have curved surfaces that allow you to cut and mulch grass.

What Material Are Mower Blades Made Of?

The material used to make the mower blades varies from manufacturer to manufacturer. The blades are hard enough to mow the lawn, but probably too soft to make a knife blade.

Typically, lawn mower blades are made of metal, such as high carbon nickel steel. The metal is not so hard that it breaks and breaks into pieces when it hits a stone, stump or other obstacles. It is softer and safer, designed to bend rather than break.

The blades are also made of plastic, which will bend and break easier than the blade of a steel mower. Plastic blades are attached to the plastic cutting disc, and metal blades are attached to the drive shaft.
