There are a variety of styles and sizes of lawn mower blades. Certain models are made specifically for specific mowers and come with an identification number engraved into the blades that are able to be referenced in the parts list in the mower’s manual.

A high-lift blade, as an example, produces a powerful suction that efficiently lifts the clippings upwards so they can be bagged. It also allows for an optimal air flow even in grass to avoid clogging.


The overall length of the mower blade and the hole pattern should be identified to choose the appropriate replacement lawnmowers blades. Also, the shear pin locating holes as well as their distance from the boss of the blade must be known. These measurements can narrow down the results of a search because they are in line with the shape and design of the specific sincere mower blades sharpeners blade to avoid damaging parts of the mower and causing vibrations.

Standard blades, often known as 2-in-1 or lift blades, are typically used on lawnmowers, as well as side discharge lawnmowers which aren’t mulching or bagging. The back edge of the blades has a slight upward turn that creates a constant cutting and suction effect.

High lift blades have a dramatic upturn on the back of the blade. They’re designed to be used for side discharge mowing. This type of blade requires more energy from the engine to be effective and may cost more in fuel, however it is good for grass that is thicker and more difficult to cut using normal blades.


The blades of lawn mowers are usually made from the most durable form of steel. Iron or other metals are a possibility. Steel is the most popular choice for mower blades since it provides a good combination of strength and durability. It is often heat-treated to create a hardened surface. This is known as tempering. It improves its durability, toughness as well as resistance to corrosion.

It is more beneficial to employ high carbon steel for cutting over low carbon steel as it is more durable. It is strong enough to stand up to trees, rocks, and other objects that could hit the blade without breaking it.

The best way to maintain the blade of a lawn mower is to make sure you use it frequently and keep it properly sharpened. The blade must also be balanced. This can be accomplished by inserting a nail into the board and then using a file to adjust the nail until it is in the middle of the blade.

It is essential to ensure that the blade is balanced regularly particularly after sharpening. Sharpening can cause the blade to be imbalanced since it takes more metal off one side than from the other. To test the balance, hang the blade on the bolt hole, and check if it looks even. If the blade is tilted towards the other side, it has to be re-filed to ensure it is balanced.


Use a special tool to sharpen a mower’s blade. It works like the drill, but it comes with a stone that is designed to hold the edge and leave no space for errors. This tool is faster and more precise than hand filing. Verify the balance by hanging the blade on a bolt that is inserted into the hole. If one of the ends is higher than the other, it will need to be filed a bit 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 remove the spark plug cable. Block the blade with blocks to hold it in place as you loosen the bolt that holds it with a ratchet or wrench. When you reinstall the blade, make sure you know which side is marked downward to ensure that it is mounted in the right place. Spray a little WD-40 or another lubricant on the bolt for mounting prior to tightening it.
