Discover How to Effortlessly Revive Dull Blades with the Ultimate Lawn Mower Blade Sharpener

Lawn mower blades are available in a wide range of sizes and styles. Some blades are made specifically for certain lawn mowers. They have a stamped part number that can be referred to in the manual.

For example, a high lift blade produces a strong suction that effectively sends clippings up so that they can be sorted. It also allows for the best air flow in grass conditions to prevent obstruction.

Size

The length of the mower blade and the hole pattern should be known to correctly pick the correct replacement lawnmower blades. The shear pin location holes, and their distance from the blade boss, must be likewise known. These measurements can narrow down results due to them being in accordance with the style and shape of a specific mower blade to avoid damaging mower components and creating vibrations.

Standard blades, sometimes referred to as 2-in-1 blades or lift blades are often used on regular lawnmowers, as well as side discharge lawnmowers which aren’t bagging or mulching. Their back edge has an upturn of a small amount that creates an ongoing cutting and suction action.

High lift blades are designed to be employed for side discharge mowing. They have an upward-facing turn on the back. This kind of blade requires greater power from the engine to perform well. It may cost a little extra in fuel expenses, but it’s great for grass that is thicker and more difficult to cut using standard blades.

Material

A lawn mower’s blade is typically made from steel, which makes it durable. Other metals, like iron, can be used. Steel is a very popular material for mower blades since it provides toughness and durability. It is typically treated with heat to harden it. The process of tempering improves the strength and durability of the material and also the resistance to corrosion.

High carbon steel is an ideal option for mowing because it is stronger than low-carbon steel which makes it more resistant to damage. It is able to withstand the impact of rocks, tree stumps and other objects that could strike the blade, but not break it.

The best method to maintain a lawn mower blade is to regularly use it and keep it properly sharpened. The blade needs to be balanced. This can be done by inserting a tiny nail into the board, and then using a file over it to move the nail so that it is in the middle of the blade.

Sharpness

Sharpness of blades is influenced by many aspects, such as the dimension of the lawn and the frequency with which it is used. Sharpening is required more often when large lawns have plenty of pebbles tree roots, rocks and weeds. A dull blade will wear out faster if you use the blade regularly.

Sharp achieve precision cutting with a sharp grass mower blade edges are required for a neat and attractive cut. This can be accomplished through a sharpening drill bit, which operates much like the bench grinder, however it is smaller and cheaper.

It is crucial to ensure that the blade is balanced regularly especially after it has been sharpened. Sharpening the blade can cause it to become unbalanced as it takes more metal off one side than from the other. The blade is hung through the bolt hole and onto a nail to check its balance. If the blade tilts towards one side, it has to be filed to balance.

Maintenance

Utilize a tool specifically designed to sharpen a mower’s blade. It functions like the drill, but it comes with an edged stone made to be able to grip the edge and leave no room for error. This tool is faster and more accurate than hand filing. Check the balance by hanging the blade on a bolt through the hole. If one of the ends is higher than the other, it needs to be filed a bit more in order to ensure it is balanced.

To prevent an engine start-up while working on a blade, turn off the engine and take out the spark plug cable. Block the blade with an object to hold it in place while you loosen the bolt that holds it by using a ratchet or wrench. After reinstalling the blade be sure to note the side that is marked downward to ensure it gets mounted in the right position. Spray a small amount of WD-40 or another lubricant on the bolt for mounting prior to tightening it.
