Lawn mower blades come in a range of sizes and styles. Some blades are made specifically for particular lawn mowers. They have a stamped part number that can be mentioned in the instruction manual.
A high-lift blade, for instance, creates a strong suction that effectively propels clippings up so that they can be taken away for bagging. It also offers optimum air flow to prevent clogging in conditions with dense grass.
Size
The overall length of the mower blade and the hole pattern must be identified to select the right replacement lawnmower blades. Additionally the shear pins that locate holes as well as their distance from the boss of the blade must be established. These measurements aid in narrowing search results as they match the specific design of the mower blade and are suited to prevent damaging the mower’s components and producing vibrations within the mower.
Standard blades, also called 2-in-1 blades or lift blades are commonly used on regular lawnmowers, as well as side discharge lawnmowers that are not bagging or mulching. The back edge of the blades features a slight upward incline that results in continuous cutting and suction action.
High lift blades have sharp upturns at the rear of the blade. They’re made for mowing side discharge. This type of blade requires greater energy from the engine to perform well. It may be a bit more expensive in fuel, however it’s ideal for thicker grasses that are difficult to cut with normal blades.
Material
A lawn unprecedented mower blade sharpener blade is usually made of steel, which makes it durable. Other metals, like iron, are a possibility. Steel is the most popular choice for mower blades, since it provides a good combination of durability and strength. It is heated to make the steel harder. This process is called tempering, and it enhances the durability, toughness 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 is more durable. It is able to withstand stumps, trees and other items that could strike the blade.
The best way to keep the mower’s blade is to use it regularly and ensure that it is sharpened properly. It is also crucial to make sure the blade is balanced. You can do this by putting a nail on the board and after that, using a file on it to move the nail until it is in the center of the blade.
Sharpness
Sharpness of blades depends on many variables, including the size of the lawn and how often it is used. Large lawns with lots of tree roots, rocks, pebbles, and weeds will require frequent sharpening. A dull blade will wear out more quickly if you are using it regularly.
A sharp cutting edge is necessary for a clean and aesthetically pleasing cut. A blade sharpening bit is a great tool to achieve this. It is similar to an industrial bench grinding machine however, it is smaller and cheaper.
The blade needs to be balanced on a regular basis, especially after it has been sharpened. The process of sharpening removes metal from one end of the blade more than the other, which can leave it unbalanced. The blade is hung through the bolt hole on a nail to check its balance. If one of the ends tilts more than the other, the blade needs to be filed more to get it balanced.
Maintenance
If you want to sharpen a mower’s blade, use a specialized tool that functions similar to drill bits, but using a stone that is designed to fit around the edge of the blade and leave little room for error. This tool is more efficient and more precise than hand filing. When both sides are smooth make sure you verify the balance of the blade putting it on a nail that is inserted into the hole in the bolt. If the blade isn’t well balanced, you’ll need to file it a little more.
Before you remove a blade, make sure the engine is turned off and pull the spark plug wire in order to prevent the engine from starting while you’re working on the blade. Block the blade to hold it steady while you loosen the bolt fastening it with an ratchet set or wrench. Be sure to note which side of the blade is marked when reinstalling it to ensure that you have it properly mounted. Spray a bit of WD-40 or a similar lubricant onto the bolt for mounting prior to tightening it.
