Lawn mower blades are available in a wide range of styles and sizes. Some blades are made specifically for particular lawn mowers. They have a stamped part number that can be mentioned in the manual.

A high-lift blade, for instance, generates a powerful suction which efficiently propels the clippings upwards so they can be bagged. It also provides the best air flow to prevent the clogging of areas with thick grass.


In order to choose the best replacement lawnmower, you must know the overall length and hole pattern of the blade. The locations of the shear pins and their distance from the boss of the blade, should also be identified. These measurements aid in narrowing the results of your search since they correspond to the design of a specific mower blade and make sure that they are not damage to the mower’s components or producing vibrations within the mower.

Standard blades, sometimes called 2-in-1 or lift blades are often used on regular lawnmowers as well as side discharge mowers that are not mulching or bagging. The back edge of the blades features a slight upward incline that results in continuous cutting and suction motion.

High lift blades have a dramatic upturn on the back of the blade. They are specifically designed for side discharge mowing. This kind of blade requires more energy from the engine to perform well. It may cost more in fuel expenses, but it is good for grasses with thicker blades that are difficult to cut using regular blades.


A Electric lawn mower blade sharpener mower blade is generally made from a type of steel that makes it tough. Iron or other metals can be used. Steel is a very popular material for mower blades since it offers a combination of robustness and durability. Heat is used to harden the steel. This is known as tempering, and it improves its durability, toughness as well as resistance to corrosion.

It is more beneficial to make use of high carbon steel when cutting than low carbon steel because it’s more durable. It can withstand the impact of rocks, tree stumps and other debris that could strike the blade, but not break it.

To maintain a lawnmower blade, it is best to keep it sharp and use it regularly. The blade must also be balanced. You can do this by placing a small nail in the board and then using a file over it to move the nail until it is in the center of the blade.


Sharpness of blades depends on various variables, including the dimensions of the lawn as well as the frequency of use. Large lawns with lots of tree roots, rocks and pebbles will require frequent sharpening. A dull blade wears out faster if you use the blade regularly.

A sharp edge for cutting is essential for a smooth and attractive cut. This can be accomplished with a sharpening drill bit, which operates much like the bench grinder, but is much smaller and less expensive.

The blade must be balanced frequently, especially after it has been sharpened. Sharpening can cause the blade to be unbalanced because it takes more metal off one side than from the other. To check the balance, hang the blade on an anchor through its bolt hole and observe whether it appears like it is level. If one side is tilted higher than the other, then the blade must be filed more to get it balanced.


Make use of a specific tool to sharpen the blade of a mower. It functions like a drill, but has a stone that is made to be able to grip the edge and leave no room for error. This tool is faster and precise than hand filing. Once both sides are sharp, examine the balance of the blade by putting it on a nail that is inserted into the bolt hole. If one end drops lower than the other, it needs to be filed slightly more in order to ensure it is balanced.

To prevent an engine start-up while working on a cutting blade, turn off the engine and take out the spark plug cable. Then, block the blade to keep it in place while you loosen the bolt fastening it with an ratchet set or wrench. When you reinstall the blade, be sure to note the side that is marked downward to ensure that it is placed in the right location. Spray a little WD-40 or a similar lubricant onto the bolt that holds it in place prior to tightening it.
