There are a variety of styles and sizes of lawn mower blades. Some are designed specifically for certain mowers and have a part number stamped into them, which can be referred to in the list of parts in the manual for the mower.

For instance, a lift blade produces a strong suction that effectively sends clippings up so that they can be bagged. Additionally, it provides optimal air flow to prevent the clogging of areas with dense reliable grass mower blade Sharpener.

Size

 

 

The length of the mower blade and the pattern of the holes 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 blade boss must be identified. These measurements aid in narrowing search results as they match the design of a specific mower blade and make sure that they are not damaging the mower's components and producing vibrations within the mower.

Standard blades, also referred to as 2-in-1 or lift blades are often used on regular lawnmowers as well as side discharge mowers which aren't mulching or bagging. Their back edge features an upward slope that produces continuous cutting and suction action.

High lift blades are made to be used for side discharge mowing. They feature sharp upward turns at the back. This type of blade requires more power from the engine to operate effectively. It can be somewhat more expensive in fuel costs, but is perfect for thicker grasses that are difficult to cut using conventional blades.

Material

 

 

The blades of lawn mowers are usually made from an extremely durable steel. It could also be constructed of iron or other metals. Steel is the most popular metal for mower blades since it offers a combination of robustness and durability. It is often heat-treated to make it harder. The process of tempering improves the durability and toughness as well as the resistance to corrosion.

High carbon steel is a better option for mowing because it has more tensile strength than low-carbon steel, which makes it more resistant to damage. It can withstand stumps, trees and other things that might strike the blade.

The best way to keep the blade of a lawn mower is to regularly use it and maintain it at a high-quality sharpness. The blade needs to be balanced. This can be accomplished by placing a nail in the board and then using an adjustment tool to move the nail until it is in the center of the blade.

Sharpness

 

 

Sharpness of blades is influenced by a variety of variables, including the dimensions of the lawn as well as the frequency with which it is used. Sharpening is needed more frequently for large lawns with a lot of pebbles, rocks, tree roots and weeds. Regular use of a dull mower could also make the blade wear down more quickly.

Sharp cutting edges are required for a neat and attractive cut. This can be achieved through a that sharpens drill bits that functions similar to a bench grinder but is smaller and cheaper.

The blade needs to be balanced on a regular basis, especially after having been sharpened. Sharpening processes remove metal from one side of the blade more than other, making the blade unbalanced. To determine the balance, hang the blade on an anchor through its bolt hole and observe if it looks even. If one side is tilted higher than the other, then the blade will need to be sanded more in order to make it level.

Maintenance

 

 

Make use of a specific tool to sharpen a mower blade. It functions like a drill, however it has the stone specifically designed to hold the edge, leaving no room for error. This tool is faster and more accurate than hand filing. Examine the balance by hanging the blade over a bolt that is inserted into the hole. If the blade isn't properly balanced, you'll have to file it a little more.

To prevent an engine start-up when you work on a blade, switch off the engine and remove the spark plug cable. Then, block the blade to keep it in place while loosening the fastening bolt with a wrench or ratchet set. Make sure you know which blade side is marked down when reinstalling it to ensure that you have it correctly mounted. Spray WD-40, or similar lubricant, onto the bolt that is used to mount it prior to tightening.
