perfect lawn mower blade sharpeners mower blades are available in a variety of designs and sizes. Some blades are specifically designed for specific lawn mowers. They are stamped with a part number that is mentioned in the instruction manual.
For example, a high lift blade generates a strong suction that effectively throws clippings upwards so they can be bagged. It also offers optimum airflow to avoid the clogging of areas with dense grass.
Size
The length of the mower blade as well as the hole pattern must be identified to select the right replacement lawnmower blades. The shear pin location holes, and their distance from the boss of the blade should also be identified. These measurements help narrow the results of a search because they are in line with the shape and design of a specific mower blade in order to prevent damaging parts of the mower and causing vibrations.
Standard blades, often called 2-in-1 or lift blades, are typically used on lawnmowers and side discharge lawnmowers which aren’t bagging or mulching. Their back edge has an upward slope that produces continuous suction and cutting action.
The high lift blades are designed to be used to cut side discharges. They feature sharp upward turns at the back. This type of blade requires more power from the engine to operate effectively. They can be somewhat more expensive in fuel costs, but is ideal for grasses with thicker tufts which are hard to cut using standard blades.
Material
The lawn mower’s blades are typically made of the most durable form of steel. It can also be made out of iron or other types of metals. Steel is a very popular material for mower blades since it offers a combination of toughness and durability. It is usually treated with heat to harden it. This process is called tempering. It improves its durability, toughness and resistance to corrosion.
High carbon steel is a better option for mowing because it is stronger than low carbon steel which makes it more resistant to being damaged. It is strong enough to stand up to rocks, tree stumps and other objects which could strike the blade.
The best way to keep the blade of a lawn mower is to regularly use it and keep it properly sharpened. The blade needs to be balanced. This can be accomplished by placing a nail in the board, and using a file to adjust it until the nail touches the middle of the blade.
Sharpness
Blade sharpness depends on various variables, including the size of the lawn and the frequency of use. Sharpening is more frequent for large lawns with plenty of pebbles rocks, tree roots and weeds. The continuous usage of a dull mower will also cause the blade to wear down faster.
Sharp cutting edges are required for a neat and attractive cut. A sharpening tool for blades will help achieve this. It works like a bench grinding machine, but it’s much smaller and less expensive.
It is crucial to ensure that the blade is balanced regularly, especially after sharpening. Sharpening process removes metal from one side of the blade more than the other, which can leave the blade unbalanced. To check the balance, put the blade on the bolt hole and observe if it looks level. If one side is tilted higher than the other, the blade will need to be sanded more in order to make it level.
Maintenance
Utilize a tool specifically designed to sharpen the blade of a mower. It is similar to a drill, however it has the stone specifically designed to grip the edge and leave no space for error. This tool is much more efficient and more precise than hand filing. Once both sides are sharp, check the balance of the blade by putting it on a nail that is inserted into the bolt hole. If one of the ends is higher than the other it needs to be filed slightly more in order to ensure it is balanced.
To prevent an engine start-up while you are working on a blade, switch off the engine, and then remove the spark plug cable. Block the blade using blocks to hold it in place while you loosen the bolt holding it by using a ratchet or wrench. Make sure you know which blade side is marked down when reinstalling it to ensure that you have it mounted correctly. Spray a bit of WD-40 or a similar lubricant onto the bolt for mounting prior to tightening it.
