distinctive lawn mower blades sharpeners mower blades are available in a wide range of designs and sizes. Some are designed specifically for specific mowers and come with the part number stamped on the blades that are able to be referenced in the list of parts in the mower’s manual.
A high-lift blade for instance, creates a strong suction which efficiently propels the clippings up so that they can be taken away for bagging. It also allows for optimal air flow in dense grass to avoid clogging.
Size
To choose the right replacement lawnmowers, you need to know the overall length and hole pattern of the blade. The shear pin location holes and their distance from the blade boss, must be likewise known. These measurements aid in narrowing search results as they match the specific design of the mower blade and make sure that they are not damaging the mower’s components and producing vibrations within the mower.
Standard blades (also known as 2-in-1 blades, also known as lift blades) are commonly used on lawnmowers equipped with side discharge and lawnmowers without mulching or bagging. The back of the blades has a slight upward turn that creates a constant cutting and suction effect.
High lift blades are characterized by an incredibly steep upturn on the back of the blade. They are designed for side discharge mowing. This kind of blade requires more power from the engine to function well. They can be a bit more expensive in terms of fuel, however it is ideal for grasses with thicker tufts that are difficult to cut with standard blades.
Material
The lawn mower’s blades are generally made from a durable type of steel. It can also be made from iron or other metals. Steel is the most popular metal for mower blades since it provides robustness and durability. It is usually treated with heat to make it harder. Tempering increases the toughness and durability as well as the resistance to corrosion.
High-carbon steel is the best option for mowing, as it has more tensile strength than low carbon steel and is more resistant to being damaged. It is able to withstand rocks, tree stumps and other things that can cause damage to the blade.
For a lawnmowers blade to last, it is best to keep it sharp, and make sure you use it frequently. It is also crucial to ensure that the blade is balanced. This can be accomplished by inserting a nail into the board, and using a file to adjust it until the nail touches the center of the blade.
Sharpness
The sharpness of your blades will depend on several factors, such as how often you use it and the size of your lawn. Sharpening is required more often for large lawns with a lot of pebbles, tree roots, rocks and weeds. The continuous use of a dull mower will also result in the blade wearing down faster.
A sharp edge for cutting is essential for a smooth and pleasing cut. This can be achieved by using a blade that sharpens drill bits, which operates much like the bench grinder, but is smaller and more affordable.
It is essential to regularly balance the blade especially after it has been sharpened. Sharpening process removes metal from one end of the blade more than the other, making the blade unbalanced. Hang the blade through the bolt hole on a nail to check its balance. If the blade tilts towards one side, it has to be filed down to make it level.
Maintenance
If you want to sharpen a mower’s blade, you should use a tool that operates much like a drill bit, but using a stone that is designed to be affixed to the edge of the blade, leaving very little space for errors. This tool is more efficient and more accurate than hand filing. After both sides are clean make sure you examine the balance of the blade hanging it on a nail through the hole in the bolt. If the blade is not balanced, you will need to file it more.
To stop an engine from starting while you are working on a cutting blade, turn off the engine and remove the spark plug cable. Then, block the blade to keep it steady while you loosen the bolt fastening it with a wrench or ratchet set. Be sure to note which blade side is marked before reinstalling it, to ensure that you have it mounted correctly. Spray a small amount of WD-40 or another lubricant on the bolt for mounting prior to tightening it.
