The best mower blades will be made of high-quality steel that will last for years, and they should be easy to install. If you’re looking for the best mowing blades.

If you’re looking to replace the mower blades on your riding lawn mower, you’ve come to the right place. This guide will explain the difference between Low-lift and high-lift blades, how to use the high-lift blades, and which material to choose. In addition, we’ll talk about the benefits of Aluminum and Stainless steel. There are many other benefits of using these blades as well. Let’s take a look at what to consider when making your choice.

Best Mower Blades

Low-lift blades

High-lift blades produce much more airflow and suction than low-lift mower blades, but the latter tend to be more efficient on sandy grounds. Low-lift mower blades, on the other hand, cut the grass more thoroughly without generating much of an upturned edge. They are particularly useful on Bermuda, St. Augustine, Bahia, and Centipede grass, as they cut at a lower angle than their high-lift counterparts.

If you’re considering replacing your low-lift mower blades, make sure you get a high-quality O.E.M. unit. Purchasing non-O.E.M. blades may void the warranty of your mower, so make sure you check the blade dimensions before buying. However, it’s best to purchase replacement blades only after consulting your manual. The dimensions of lawn mower blades differ depending on the manufacturer, so it’s important to get the right size for your machine.

Another type of low-lift mower blade is called a “gator blade,” which is particularly helpful when you’re trying to fertilize your lawn. These blades have a unique design that combines mulching, bagging, and side discharge functions into one. Their serrated edge helps remove grass clippings efficiently, while their curved profile allows for maximum suction. This type of mower blade is often suited to narrow, low-lying lawns, and is also ideal for a mulching job.

High-lift blades

High-lift blades on lawn mowers produce more suction and airflow, ensuring that clippings are discharged quickly and efficiently. They can be used to achieve a level cut on longer grass, and are effective at preventing clumping on thick grass. They are not recommended for lawns with sandy soil, however, as they circulate grit and can damage the mower deck. Listed below are some advantages and disadvantages of high-lift mower blades.

Blades for high-lift lawn mowers should not be as sharp as razor blades. In addition to cutting the grass, high-lift blades can chip or be damaged by rocks. Always check the blade size before purchasing new high-lift mower blades. The size of the blade and bolts that secure the blades vary by manufacturer. If you are replacing a blade for a Kubota lawn mower, make sure to use a 22 or 24-millimeter socket.

Mulching blades are another type of high-lift mower blade. They are especially helpful for cutting and mulching grass clippings. Mulching blades are specially designed to collect clippings and disperse them as a nutrient-rich fertilizer. Mulching blades are best for lawns with grainy soil. High-lift mower blades are the best choice for a lawn that is rarely mowed because they can easily cut thick grass without clogging the mower deck.

Stainless steel

One of the biggest advantages of stainless steel mower blades is their rust-proof properties. Unlike their steel counterparts, these blades don’t rust and are better at holding their edge. In addition, these blades are lighter in weight and equally as durable. This allows them to work well in all kinds of weather conditions, including rain. In addition, they have razor-sharp blades that cut the grass gently in all directions. Unlike their steel counterparts, they have a double-sided tip for additional durability and sharpness.

If you want a pristine, carpet-like lawn, a stainless steel mower blade is the right choice. These blades are easy to install and remove, and are equipped with 36 nickel-plated screws for easy mounting. Not only do these blades improve the efficiency of your lawnmower, but they also extend its life span. They are made of high-quality stainless steel and come with a resealable package to keep them protected from moisture and dirt.


You may be wondering whether an aluminum mower blade will be right for your lawnmower. The good news is that they are quite versatile. Whether you’re looking for a mulching mower blade or a side discharge mower blade, these blades are an excellent choice for commercial or residential lawnmowers. These blades can withstand a wide range of wear and impact conditions. The best way to decide whether an aluminum mower blade is right for you depends on the type of job you’ll be performing with it.

The main difference between metal and aluminum mower blades is the material used to make them. While most major lawnmower manufacturers use heat-treated blades, some may skip this process in order to cut costs. Heat-treated blades are harder, so they have a greater capacity to cut and will last longer. This type of blade also tends to be more affordable than aluminum and may not be as durable as an aluminum blade. Also, these blades may not be as effective for cutting wet grass.


You may wonder what the difference is between regular and fiberglass blades for mowers. While both kinds are good for the job, choosing the correct blade is vital for the success of your lawn care project. Here are some of the advantages and disadvantages of regular blades and fiberglass blades. Regular blades use suction cups to pull up the grass while fiberglass blades allow a small amount of air to pass through them. Your lawn type is the most important factor when choosing your blades.

Low-lift blades are usually three to four inches in height and require less power from your lawn mower. Because of their low-lift design, they grant longer life to your mower blades. High-lift blades create more suction and deterioration over time, and they are generally not recommended for mowing large lawns with tall grass. Medium-lift blades are a good compromise between high-lift and low-lift blades. Low-lift blades have a low lift angle, resulting in a lower airflow. High-lift blades, on the other hand, have a steeper curvature and create a stronger suction.

Aluminum-coated steel

Before you start sharpening your lawn mower blade, you should first remove the blade and clean the bowl around it. Although some mowers are equipped with sharpening tools, it is better to remove the blade to better see the cutting edges. If you are not sure how to do this, you should check the instructions provided with the mower. Afterward, sharpening the blade is as easy as it seems. Using the blade balancer will ensure that the mower blade is balanced and free of debris.

Another benefit of aluminum-coated steel mower blades is their durability. While they are not as durable as steel mower blades, they do not corrode. A common cause of corrosion is when mowers are left out through the winter with the grass still on the deck. This fermented grass produces an acidic byproduct that corrodes aluminum. Unfortunately, many owners fail to take proper care of their lawn mower blades, and their mower is left in the garage until the grass is long enough to be cut. And after that, the lawn mower is forgotten for months at a time.

Steel with high carbon content

Traditionally, steel with high carbon content for mower blades has been used in industrial applications due to its excellent toughness and flexibility. However, these high carbon steels have been found to have less brittleness and are prone to edge deformation than traditional steels. Furthermore, blades made of high carbon steel require more maintenance and replacement than conventional blades, and their use is mainly restricted to lawn mowers.

For lawn mower blades, the steel must first be tempered or hardened. This process strengthens the structural bonds and improves the blade capacity. While this process is required for high carbon steel, some manufacturers stop at this stage and use only tempering as a final step. In such a case, the blade will not last as long as a hardened blade. Moreover, some manufacturers may use lower-quality blades without undergoing the heat-treating process.

The highest-quality steel for mower blades is the spiral part on the golf mower. High carbon steel is the preferred choice for mower blades made by John Deere and Jacobsen. It is important to understand the properties of different types of steel for rotary and cylinder blades. Despite their different uses, mower blades require relatively soft steel to prevent them from splintering when hitting a rock.

Stainless steel with high carbon content

Non-stainless steel and stainless steel both have high carbon content. Stainless steel is stronger than non-stainless steel but it can be more difficult to sharpen, which is why most mower blades have coatings to prevent rust. However, stainless steel has certain advantages over non-stainless steel, including better wear resistance, a higher sharpening ability, and a longer lifespan.

Carbon steels made in Japan are called SK3, SK4, or SK5. A lower number means the steel is less prone to impurities and is, therefore, more durable. Another proprietary steel is CPM 4V, which has high impact toughness and good wear resistance. CPM 9V is a modification of CPM 10V, which contains lower carbon and more vanadium for toughness. Lastly, CPM CRU-WEAR is proprietary steel that is superior to ingot-made Cru-Wear.

Unlike AUS-8, which is made of low-carbon steel, D2 has higher carbon content, a harder edge, and lower tempering resistance. Stainless steel with high carbon content is harder than non-stainless steel but it is just as corrosive. And while it is more expensive than non-stainless steel, it is also less prone to corrosion than carbon-based blades.
