Lawn mower blades are available in a range of designs and sizes. Certain blades are designed specifically for particular lawn mowers. They come with a stamped part number that can be referenced in the manual.
A high-lift blade, as an instance, creates a strong suction that efficiently lifts the clippings upwards so they can be stored. Additionally, it provides optimal air flow to prevent clogging in conditions with thick grass.
Size
The length of the mower blade as well as the pattern of the holes must be figured out to ensure that you pick the correct replacement lawnmower blades. Also the shear pins that locate holes as well as their distance from the boss of the blade should be known. These measurements can help narrow the results of your search since they correspond to a particular mower blade’s design and are suited to prevent damaging the components of the mower and producing vibrations within the mower.
Standard blades (also called 2-in-1 blades, also known as lift blades) are commonly used on lawnmowers equipped with side discharges and lawnmowers that do not have bagging or mulching. Their back edge is an upward slope that produces a constant suction and cutting.
High lift blades are characterized by a dramatic upturn to the back of the blade. They’re made for side discharge mowing. This type of blade requires greater power from the engine in order to perform well. It may be a bit more expensive in fuel expenses, but it’s great for grasses with thicker blades that are difficult to cut with standard blades.
Material
The lawn mower’s blades are generally made from The Smart Choice For Effective Lawn Mower Blades Sharpening most durable form of steel. Metals like iron or other can be utilized. Steel is the most popular option for mower blades as it has a superior combination of strength and durability. It is often heat-treated to create a hardened surface. The process of tempering improves the toughness and durability, as well as resistance to corrosion.
It is better to use high carbon steel for cutting over low carbon steel as it is more durable. It can withstand tree stumps, rocks and other debris that could be thrown at the blade and not damage it.
In order to maintain the blade of a lawnmower, it is best to keep it sharp, and make sure you use it frequently. The blade must also be balanced. You can do this by placing a small nail on the board and then using a file over it to adjust the nail so that it is in the middle of the blade.
Sharpness
The sharpness of your blades will depend on a variety of factors, like 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 wears out more quickly if you are using it regularly.
A sharp edge for cutting is necessary for a clean and attractive cut. This can be accomplished by using a blade cutting drill bit that can be sharpened that functions similar to the bench grinder, but is much smaller and less expensive.
It is important to ensure that the blade is balanced regularly particularly after sharpening. Sharpening the blade can cause it to be imbalanced since it takes more metal off one side than the other. To test the balance, place the blade on a nail through its bolt hole and see if it looks like it is level. If the blade tilts towards the other side, it will need to be filed to balance.
Maintenance
When sharpening a mower blade, make use of a tool that operates much like a drill bit, but with a specially-designed stone to fit around the edge of the blade, leaving the least amount of room for mistakes. This tool is quicker and more precise than hand-filing. Check the balance of the blade by placing it over a bolt through the hole. If the blade is not balanced, you will need to file it a little more.
Before you remove a blade, ensure that your engine is shut off. Pull the spark plug wire to stop the engine from accidentally beginning while working on the blade. Block the blade in order to hold it in place while you loosen the bolt that fastens it using the help of a ratchet or wrench. Make sure you know which blade side is marked down when you reinstall it to ensure you have it correctly mounted. Spray WD-40, or similar lubricant, onto the mounting bolt before tightening.
