There are many different styles and sizes of entertaining lawn Mower blades sharpeners mower blades. Certain blades are designed specifically for certain lawn mowers. They have a stamped part number which can be referred to in the instruction manual.
For instance, a high lift blade creates a powerful suction that efficiently throws clippings upwards so they can be bagged. It also provides the best air flow to prevent clogging in conditions with dense grass.
Size
In order to choose the best replacement lawnmower, you must know the length of the blade and pattern of the holes on the blade. The locations of the shear pins and their distance from the blade boss, must also be known. These measurements can help narrow search results as they match a particular mower blade’s design and are suited to prevent damaging the components of the mower and creating vibrations in the mower.
Standard blades, also called 2-in-1 or lift blades are often used on regular lawnmowers as well as side discharge mowers that are not bagging or mulching. Their back edge is a slight upturn that generates an ongoing cutting and suction action.
High lift blades feature an incredibly steep upturn at the rear of the blade. They are specifically designed for mowing side discharge. This blade type requires more engine power to function well. It is somewhat more expensive in fuel costs, but is great for thicker grasses which are tough to cut using standard blades.
Material
The lawn mower’s blades are usually made from the most durable form of steel. Other metals, like iron, can be utilized. Steel is the most sought-after choice for mower blades, as it has a superior combination of strength and durability. It is heated to harden the steel. The process of tempering increases the toughness and durability as well as the resistance to corrosion.
It is better to employ high carbon steel for mowing than low carbon steel because it is more durable. It can withstand trees, rocks, and other debris that could be thrown at the blade and not damage it.
The best method to maintain the mower’s blade is to make sure you use it frequently and keep it properly sharpened. It is also crucial to make sure the blade is balanced. This can be accomplished by putting a nail into the board and then using an adjustment tool to move the nail until it is in the center of the blade.
Sharpness
Blade sharpness depends on a variety of variables, including the dimension of the lawn and how often it is used. Sharpening is required more often when large lawns have a lot of pebbles, rocks, tree roots and weeds. A regular use of a dull mower will also result in the blade wearing down quicker.
A sharp edge for cutting is essential for a smooth and aesthetically pleasing cut. A blade sharpening bit can achieve this. It works like an industrial bench grinding machine but it’s much smaller and much less costly.
It is crucial to ensure that the blade is balanced regularly especially after it has been sharpened. Sharpening processes remove metal from one end of the blade faster than the other, which can leave the blade unbalanced. Place the blade through the bolt hole on a nail to check its balance. If one end tilts higher than the other, the blade must be filed more in order to make it level.
Maintenance
If you want to sharpen a mower’s blade, you should use a tool that functions similar to a drill bit, however using a stone that is designed to hug the edge of the blade and leave very little space for mistakes. This tool is much faster and more precise than hand-filing. After both sides are clean make sure you examine the balance of the blade by hanging it from an anchor through the bolt hole. If one of the ends is higher than the other, it needs to be filed a bit further to ensure that it is balanced.
To prevent an engine start-up while working on a blade, switch off the engine and remove the spark plug cable. Block the blade to keep it in place while loosening the bolt that fastens it using the help of a ratchet or wrench. Remember which blade side is marked down when you reinstall it to ensure that you have it correctly mounted. Spray WD-40, or a similar lubricant, on the bolt that is used to mount it before tightening.
