Buying Guide; Factors to consider when choosing lawn mower blades

When looking for the best aftermarket lawn mower blades, you'll need to understand their structure and evaluate different factors so that the blades can meet your mowing needs. Although most mower blades are universal, no one size fits all. Below are critical features that you need to keep in mind when searching for replacement blades.

Type of blade; Lifting or Mulching

Mower blades are either designed to lift grass or getting rid of /mulch grass quickly. Lifting blades cut and collect grass into a bag, usually at the back of the mower, for disposal. These blades work by creating an upward air movement that lifts and cut the grass. The lifting blades come in three different forms;

Low Lift

Low lift lawn mower blades provide low suction power, and they are ideal for small mowers with limited workspace. You can use low lift blades to trim a typical front or back yard. In addition, these blades require little maintenance and work well for residential use.

Medium Lift

Medium lift blades are generally larger than low lift blades, and they are perfect for mowing thicker grass and weeds. And because of this versatility, medium-lift blades are the easiest to find, and they are used for both commercial and residential purposes.

High Lift

High lift lawn mower blades provide the highest suction power, and they are ideal for shearing through thicker grass quickly. Also, they tend to work for extended periods since they are designed to withstand heavy use. Overall they consume more power but take less time to complete a job.

Mulching blades, on the other hand, are preferred for fine mulching and for adding a creative and professional touch to your lawn. Mulching blades have a curved design that allows them to function in 3 ways;

  • The blade pulls and cuts the grass
  • The grass clippings are then drawn inside the deck, where they are chopped into finer pieces.
  • The blade releases pressure to blow the small clippings back onto the lawn or into a bagger.

Mounts

Mounts refer to the center used for installation. The center hole comes in different shapes, the common ones being circular and star-shaped. For the star-shaped mounts, the blades will either have 5 points or 6 points, and you'll need to choose the correct outline for your specific mower mount. When replacing the blades, you'll need to ensure that the center hole is the same as the previous one.

Tilt angle

The angle in which the blades are tilted is going to make a big difference in how you go about operating the machine, cutting your grass, and bagging the clippings. For example, if you intend to leave the grass clippings on the lawn, you can use a low-angled blade. However, if you want to bag them into a container, a higher-angled blade will be the best option.

The thickness of the blades

Generally, the thicker the blades, the more efficient and powerful they are when it comes to mowing through a large garden in less time. However, they should not be too thick as they can difficult to handle. A thin blade, on the other hand, allows for more refined cuts, but they are not as powerful. In the end, it depends on your mowing needs and the desired mowing experience.

Length and width

The length and the width of the blades are probably one of the trickiest aspects you'll need to consider. The length and the width should not be too long, as it might be challenging to manage. Neither they should not be too short since it will leave uncut strips on your lawn and make the process slower and harder. As such, it is always a good idea to find the perfect balance of the two aspects by taking some measurements of your machine to match the blades.

Frequently Asked Questions and Answers

​Question 1: How often should I replace my lawn mower blade?

Answer: This will depend on the extent and frequency of your mowing. For example, a homeowner may only require to replace the blade once per year or after every two years.

Question 3: Do you need to sharpen a new mower blade?
