Factors to Consider When Buying the Best Lawn Mower Blade

a). Type of Blade

You must check the type of blade that suits your lawn mower perfectly. Most lawnmower blades have similar basic features like an edge for dealing with grass and other outgrowths on your yard, gardens or lawns. However, these tools differ through the various shapes designed to achieve specific goals in landscaping. Below are some of the different variations you can buy.

1. Low lift blade

If you live in a residential area with little outdoor space, you should consider buying low lift blades. These tools are much easier to power, maintain, and are found in light-duty lawn mowers. The low lift blades are specially designed to use on sandy soil since they have low suction power. In addition, they have fewer curved edges compared to the standard ones. 

These lawn mower blades are usually available in three to four inches in size, and they use less power. The fantastic thing is that the low lift blades do not stress your mower much, which will lead to an extended life span. Hence if you are looking for blades that will offer long-term durability, the low lift is the best option.

2. Standard or medium-lift blade

Medium lift blades are more significant than the low-rated ones. This type of blade works best with thick grass, dense grass, and some small weeds because they are larger and can handle more strenuous tasks. Although these blades are sturdy enough for commercial and residential use, they will not harshly cut your grass. These blades are rotated horizontally, and they tend to have a slight curve. Hence, in most cases, they are called straight mower blades. These blades are designed to be used on light grass, and they could also be used on both dry and damp areas. 

3. High lift blades

The blade is designed to clear out thickly growing yards and lawns. These types are the most viable and durable option and work well and fast if you do frequent yard work. Moreover, high lift mower blades can help ease collecting grass clippings. You can use push mowers with bags at the back to reduce the work into maintaining a neat yard. These blades usually come with a vertical angle on the edges that enables maximum airflow through the blades.

Most blades in this category usually range from one to twenty-one inches in length, making them perfect for yards with tall grass. However, the blades will not work as well on sandy terrains compared to other blades since it maximizes airflow, making them suck in dirt or sand along with the grass. In most cases, the dirt will settle in the cutting deck, which will cause premature wear off.

4. Mulching blades

Mulching blades are specialized tools that can chop grass into fine pieces to leave on the yard to add fertilizer naturally. The edge ensures that your outdoor spaces do not look messy once you are done. Additionally, you can get low, medium and high lift options for mulching blades. So if you are looking to replenish the soil in your land, this is a perfect option.

You could use a mulching blade in push or riding mowers. While compared or other blades, the mulching blade will have a more cutting edge, allowing your lawnmower to cut grass finely. In addition, they are usually more curved on the outer and inner surface, which allows trimmed grass to be transferred to the cutting deck, where they are cut into smaller pieces. The inner curves then allow the small particles to settle on the ground.

5. Gator Blade

Like a mulching blade, the gator blades are also a perfect option for fertilizing the soil. However, the Gator blades are designed to be more efficient and create maximum suction on the grass. They usually have a particular angle on the teeth of a mulching blade. The fantastic thing is that the gator teeth push the grass to the sharp cutting edge of your lawnmower as you work. This way, the grass is cut over and over again into tiny pieces.

b). Blade Construction

There isn't a wide range of variations in the blade length of most products. The shortest ones are 16.75 inches, while the longer ones can go up to 22 inches. It may seem evident that longer blades mean more efficient cutting; however, you need to ensure the blades fit your equipment.

Most lawn mowers allow you to use replacement blades that are not the same size as the original ones. As a rule of thumb, shorter ones mean more work, but longer ones may not fit. Thus, you need to find the sweet spot to make your work easier.

In terms of the width, ensure the blade fits the specifications laid out by the lawnmower manufacturer. A wide blade may not match the deck size or cause damage to the compartment. Alternatively, a narrow blade does not improve the efficiency of the lawnmower's motor.

The materials used in making the blades have a bearing on how durable the tool is. Strong stainless steel is one of the most popular builds for these products because it is rust-resistant and works well when sharp. Plus, it is one of the hardest metals, and it is guaranteed to last long.

c). Blade Holes

Lawnmowers have a mounting hole for securing the blades. Some have a 6-or-5-point star center hole attachment to install your replacement blade. Also, it would be best if you considered the diameter of these attachments as they can vary from 1 inch to 0.5 inches. Finally, check the lawnmower manual if you doubt whether your purchase will work with the machine you have.

d). Blade Length

Obviously, the blade length is another very crucial factor to consider. You will need to measure the length of your existing blade and get the appropriate replacement blade. The majority of blades fall within the range of 16 inches to 22 inches, depending on the OEM replacement. However, you may find others with longer blades, but they are usually original blades in most cases. In most cases, the original blades are advantageous since they will provide a wider cut. You must purchase a blade with adequate length to fit in place firmly.
