Lawn mower blades are available in a variety of styles and sizes. Some are specifically designed for specific mowers and come with an identification number engraved into them, which can be referred to in the list of parts in the mower’s manual.

For instance, a lift blade creates a powerful suction that efficiently sends clippings up so that they can be bagged. The blade is also able to provide the best air flow in grass conditions to prevent the clogging.


The length of the mower blade and the hole pattern should be identified to pick the correct replacement lawnmower blades. Also the shear pins used to locate holes and their distance to the boss of the blade must be established. These measurements aid in narrowing the results of your search since they correspond to a particular mower blade’s design and fit to avoid damaging the components of the mower and producing vibrations within the mower.

Standard blades, also called 2-in-1 or lift blades, are typically used on lawnmowers and side discharge lawnmowers which aren’t mulching or bagging. The back of the blades has a slight upward incline that results in a constant cutting and suction effect.

High lift blades feature a dramatic upturn to the back of the blade and are specifically designed for mowing side discharge. This type of blade requires greater power from the engine to work well and can cost a little extra in fuel costs but it’s ideal for grasses with thicker blades that are difficult to cut with standard blades.


The blades of lawn mowers are usually made from a durable type of steel. Other metals, like iron, are a possibility. Steel is the most popular metal for mower blades as it has a mix of durability and strength. It is heated to make the steel harder. This process is known as tempering and improves its durability, toughness as well as resistance to corrosion.

It is more beneficial to use high carbon steel for mowing rather than low carbon steel since it is more durable. It is strong enough to stand up to tree stumps, rocks and other objects that could be thrown at the blade and not damage it.

The best method to maintain the blade of a top Lawn mower Blades sharpener mower is to use it regularly and ensure that it is sharpened properly. The blade should also be balanced. You can do this by inserting a tiny nail on the board and then using a file on it to adjust the nail so that it is in the center of the blade.


Blade sharpness depends on various variables, including the dimension of the lawn and the frequency with which it is used. Sharpening is more frequent on large lawns that have lots of pebbles, trees, rocks and weeds. Regular use of a mower that is dull could also make the blade wear down quicker.

A sharp edge for cutting is required for a neat and attractive cut. A blade sharpening bit will achieve this. It works like the bench grinder, but is much smaller and cheaper.

It is crucial to ensure that the blade is balanced regularly especially after sharpening. Sharpening can cause the blade to become unbalanced as it takes more metal off one side than from the other. To test the balance, place the blade on the bolt hole and observe whether it appears like it is level. If one side is tilted higher than one, the blade needs to be filed further to ensure it is balanced.


Make use of a specific tool to sharpen the blade of a mower. It works like a drill, however it has a stone that is designed to hold the edge, leaving no space for error. This tool is quicker and more precise than hand-filing. Examine the balance by hanging the blade over a bolt through the hole. If the blade isn’t balanced, you will need to file it more.

Before removing a blade, ensure that the engine is off. Then, pull the spark plug wire in order to prevent the engine from accidentally beginning while working on the blade. Then, block the blade to keep it in place while you loosen the fastening bolt with the help of a ratchet or wrench. After reinstalling the blade be sure to note the direction of the blade to ensure that it is placed in the proper position. Spray a bit of WD-40 or a similar lubricant onto the bolt that holds it in place prior to tightening it.
