memorable lawn mower blades sharpeners mower blades are offered in a wide range of styles and sizes. Certain blades are designed specifically for specific lawn mowers. They come with a stamped part number which can be mentioned in the manual.
For example, a high lift blade generates a strong suction which 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 clogging.
Size
In order to choose the best replacement lawnmower, you must know the overall length and hole pattern of the blade. The location of the shear pin holes and their distance from the boss of the blade, must be likewise known. These measurements narrow down search results because they match the design and fit of a particular mower blade in order to prevent damaging parts of the mower and causing vibrations.
Standard blades (also known as 2-in-1 blades or lift blades) are commonly used on lawnmowers that have side discharge, and on lawnmowers with no bagging or mulching. Their back edge has a slight upturn that generates a constant suction and cutting.
High lift blades are made to be used to cut side discharges. They feature sharp upward turns at the back. This blade type requires more power from the engine to operate effectively. It is somewhat more expensive in terms of fuel consumption, but is perfect for thicker grasses that are difficult to cut using regular blades.
Material
The blades of lawn mowers are generally made from a durable type of steel. Other metals, like iron, can be utilized. Steel is the most popular metal for mower blades as it offers a combination of durability and strength. It is heated to make the steel harder. The process of tempering improves the durability and toughness as well as the resistance to corrosion.
High-carbon steel is a better choice for mowing as it has a higher tensile strength than steel with low carbon, which makes it more resistant to damage. It is able to withstand rocks, tree stumps and other items that can cause damage to the blade.
In order to maintain the blade of a lawnmower it is important to keep it sharpened and make sure you use it frequently. The blade should also be balanced. This can be done by placing a nail in the board, and using a file to adjust it until the nail touches the middle of the blade.
Sharpness
The quality of your blades will depend on a variety of factors, including how much you are using it, as well as the size of your lawn. Sharpening is more frequent for large lawns with a lot of pebbles, tree roots, rocks and weeds. A dull blade will wear out more quickly if you are using frequently.
For a neat and pleasing cut, a sharp cutting edge is vital. A sharpening tool for blades is a great tool to accomplish this. It works like an industrial bench grinding machine however, it is smaller and less expensive.
The blade should be balanced frequently, especially after it has been sharpened. The process of sharpening removes metal from one end of the blade more than the other, leaving it unbalanced. To check the balance, put the blade on the bolt hole, and check whether it is like it is level. If one side is tilted higher than one, the blade will need to be sanded further to ensure it is balanced.
Maintenance
Use a special tool to sharpen a mower’s blade. It functions like the drill, but it comes with the stone specifically designed to grip the edge, leaving no room for error. This tool is more efficient and more accurate than hand filing. When both sides are smooth make sure you verify the balance of the blade hanging it on a nail through the bolt hole. If one end drops lower than the other it’s time to be filed slightly more to be properly balanced.
Before you take off a blade make sure your engine is shut off and pull the spark plug wire in order to prevent the engine from accidentally getting started while you work on the blade. Block the blade in order to hold it steady while you loosen the bolt that fastens it using the help of a ratchet or wrench. When reinstalling the blade, make sure you know the direction of the blade to ensure that it is placed in the correct position. Spray WD-40, or a similar lubricant, on the bolt for mounting prior to tightening.
