Lawn mower blades come in a wide range of sizes and styles. Certain blades are designed specifically for specific lawn mowers. They come with a stamped part number which can be referenced in the instruction manual.



For instance, a high lift blade produces a strong suction that efficiently throws clippings upwards so they can be bagged. It also allows for the best air flow in grass, preventing the clogging.


Size


The overall length of the stylish mower blades sharpeners blade as well as the hole pattern must be known to correctly pick the correct replacement lawnmower blades. Additionally the shear pins that locate 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 design and fit of a specific mower blade in order to prevent damaging mower components and creating vibrations.



Standard blades, sometimes referred to as 2-in-1 blades or lift blades are commonly used on regular lawnmowers and side discharge lawnmowers that do not use mulching or bagging. The back edge of blades is slightly upward incline that results in continuous cutting and suction effect.



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


Material


The lawn mower's blades are usually made from the most durable form of steel. It can also be made of iron or other metals. Steel is the most sought-after option for mower blades as it has a superior combination of durability and strength. Heat is used to make the steel harder. This process is called tempering and improves its durability, toughness and resistance to corrosion.



High-carbon steel is a better choice for mowing as it has more tensile strength than low-carbon steel which makes it more resistant to being damaged. It is strong enough to stand up to rocks, tree stumps and other objects which might strike the blade.



The best way to maintain a lawn mower blade is to make sure you use it frequently and ensure that it is sharpened properly. It is also important to ensure that the blade is balanced. It is possible to do this by inserting a tiny nail into the board, and then using a file on it to move the nail so that it touches the middle of the blade.


Sharpness


Sharpness of blades is influenced by a variety of factors, including the dimension of the lawn and the frequency with which it is used. Sharpening is needed more frequently for large lawns with plenty of pebbles trees, rocks and weeds. A dull blade wears out quicker if you utilize it regularly.



For a smooth and beautiful cut for a neat and pleasing cut, a sharp cutting edge is essential. This is possible by using a blade cutting drill bit that can be sharpened that functions similar to the bench grinder, however it is smaller and cheaper.



It is essential to regularly balance the blade especially after sharpening. Sharpening the blade can cause it to be unbalanced because it removes more metal from one side than the other. To check the balance, hang the blade on an anchor through its bolt hole and see whether it is level. If one side is tilted higher than the other, the blade needs to be filed more in order to make it level.


Maintenance


When you are sharpening the mower blade, make use of a tool that functions similar to drill bits, but using a stone that is designed to hug the edge of the blade and leave very little space for errors. This tool is faster and more precise than hand-filing. Check the balance of the blade by placing it on a bolt that is inserted into the hole. If the blade isn't well balanced, you'll need to file it more.



To avoid an engine starting up while you are working on a blade, turn off the engine, and then remove the spark plug cable. Block the blade with blocks to hold it in place as you loosen its fastening bolt with a ratchet or wrench. After reinstalling the blade remember the side that is marked downward to ensure that it is placed in the correct position. Spray WD-40, or a similar lubricant on the mounting bolt prior to tightening.
