There are numerous designs and sizes of lawn mower blades. Some blades are specifically designed for certain lawn mowers. They come with a stamped part number that is mentioned in the Manual lawn mower blade sharpener.      A high-lift blade, for instance, creates a strong suction that efficiently lifts the grass clippings to the point that they can be taken away for bagging. It also provides the best air flow to prevent the clogging of areas with thick grass.      Size      To choose the right replacement lawnmowers, you need to know the overall length and pattern of the holes on the blade. Also, the shear pin locating holes as well as their distance from the boss of the blade must be identified. These measurements help narrow results due to them being in accordance with the shape and design of a particular mower blade to avoid damaging components of the mower and causing vibrations.      Standard blades, often referred to as 2-in-1 or lift blades, are often used on regular lawnmowers, as well as side discharge lawnmowers that are not bagging or mulching. Their back edge has an upturn of a small amount that creates continuous cutting and suction action.      High lift blades feature sharp upturns on the back of the blade and are designed for side discharge mowing. This kind of blade requires more power from the engine in order to work well and can cost more in fuel, however it is good for grasses with thicker blades that are difficult to cut using regular blades.      Material      The blade of a lawn mower is generally made from a type of steel that makes it tough. It can also be made of iron or other metals. Steel is a popular material for mower blades since it offers a combination of robustness and durability. It is often heat-treated to create a hardened surface. This process is called tempering and improves its durability, toughness as well as resistance to corrosion.      High-carbon steel is a better option for mowing, as it is stronger than steel with low carbon and is more resistant to damage. It is strong enough to stand up to rocks, tree stumps and other items that could hit the blade.      For a lawnmowers blade to last it is important to keep it sharp, and use it regularly. It is also crucial to make sure the blade is balanced. This is accomplished by putting a nail into the board and then using the file to adjust the nail until it is in the center of the blade.      Sharpness      The quality of your blades is dependent on many factors such as how often you utilize it as well as the dimensions of your lawn. Large lawns with lots of trees, rocks pebbles, weeds, and rocks will require frequent sharpening. A dull blade will wear out quicker if you utilize it regularly.      For a smooth and beautiful cut an edge that is sharp is vital. This is possible by using a blade sharpening drill bit, which operates much like a bench grinder but is smaller and more affordable.      It is essential to ensure that the blade is balanced regularly, especially after sharpening. Sharpening process removes the metal from one part of the blade more than the other, leaving the blade unbalanced. Place the blade through the bolt hole on nails to test its balance. If the blade tilts to one side, it has to be re-filed to ensure it is balanced.      Maintenance      Make use of a specific tool to sharpen a mower's blade. It works like a drill, however it has the stone specifically designed to grip the edge and leave no room for error. This tool is faster and precise than hand filing. Check the balance by hanging the blade over a bolt through the hole. If the blade isn't properly balanced, you'll have to file it more.      To prevent an engine start-up while working on a blade, switch off the engine, and then remove the spark plug cable. Block the blade using blocks to hold it in place as you loosen the bolt that holds it with a ratchet or wrench. Remember which side of the blade is marked down when reinstalling it to ensure that you have it properly mounted. Spray a small amount of WD-40 or a similar lubricant onto the mounting bolt before tightening it.
