There are a variety of types and sizes of lawn mower blades. 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 manual of the mower.
For instance, a lift blade creates a powerful suction which efficiently sends clippings up so that they can be bagged. Additionally, it provides optimal air flow to prevent getting clogged in areas of dense instructive grass mower blades sharpener.
Size
In order to choose the best replacement lawnmower, you must know the length of the blade and hole pattern of the blade. Also the shear pins used to locate holes and their distance to the blade boss must be established. These measurements can help narrow results because they are based on the specific design of the mower blade and fit to avoid damage to the mower’s components or creating vibrations in the mower.
Standard blades (also called 2-in-1 blades, also known as lift blades) are commonly used on lawnmowers with side discharge and lawnmowers without mulching or bagging. The back of the blades features a slight upward turn, which creates an ongoing cutting and suction motion.
The high lift blades are designed to be employed for side discharge mowing. They feature a sharp upward turn at the back. This kind of blade requires more engine power to operate effectively. It is slightly more costly in terms of fuel, however it is ideal for grasses with thicker tufts which are hard to cut using regular blades.
Material
The blades of lawn mowers are usually made from a durable type of steel. It is also made out of iron or other types of metals. Steel is the most popular metal for mower blades because it offers a combination of toughness and durability. It is usually treated with heat to make it harder. Tempering increases the strength and durability of the material, as well as resistance to corrosion.
It is more beneficial to make use of high carbon steel for cutting than low carbon steel because it’s more durable. It is able to withstand trees, rocks and other things that can hit the blade.
The best way to maintain a lawn mower blade is to make sure you use it frequently and ensure that it is sharpened properly. It is also important to balance the blade. This can be done by placing a small nail into the board, and after that, using a file on it to adjust the nail until it reaches the center of the blade.
Sharpness
The quality of your blades depends on many factors such as how often you utilize it as well as the dimensions of your lawn. Sharpening is needed more frequently on large lawns that have plenty of pebbles trees, rocks and weeds. Regular use of a mower that is dull will also make the blade wear down quicker.
A sharp cutting edge is essential for a smooth and aesthetically pleasing cut. A sharpening tool for blades can help achieve this. It functions like an industrial bench grinding machine but is much smaller and less expensive.
The blade needs to be balanced on a regular basis, especially after it has been sharpened. Sharpening may cause the blade to be imbalanced since it takes more metal off one side than the other. Place the blade through the hole in the bolt and onto an anchor to verify its balance. If the blade tilts to the other side, it will need to be re-filed to ensure it is balanced.
Maintenance
Use a special tool to sharpen the blade of a mower. It works like the drill, but it comes with a stone that is designed to grip the edge and leave no room for errors. This tool is faster and precise than hand filing. Examine the balance of the blade by placing it on an anchor through the hole. If the blade isn’t balanced, you will need to file it a little more.
Before you take off a blade make sure the engine is off. Pull the spark plug wire to prevent the engine from accidentally starting while you’re working on the blade. Then, block the blade to hold it in place while you loosen the fastening bolt with the help of a ratchet or wrench. Be sure to note which side of the blade is marked when reinstalling it to ensure you have it correctly mounted. Spray WD-40, or a similar lubricant, onto the bolt for mounting before tightening.
