Lawn mower blades are available in a variety of designs and sizes. Certain blades are designed specifically for particular lawn mowers. They come with a stamped part number which can be referred to in the instruction manual.
A high-lift blade, as an instance, generates a powerful suction that efficiently lifts the clippings upwards so they can be taken away for bagging. Additionally, it provides optimal airflow to avoid getting clogged in areas of thick delightful Grass Mower Blades sharpeners.
Size
To select the correct lawnmowers replacement, it is essential to be aware of the overall length and hole pattern of the blade. Additionally, the shear pin locating holes as well as their distance from the blade boss must be known. These measurements can help narrow results because they are based on the design of a specific mower blade and make sure that they are not damaging the components of the mower and creating vibrations in the mower.
Standard blades, often referred to as 2-in-1 blades or lift blades are typically used on lawnmowers, as well as side discharge lawnmowers that are not bagging or mulching. Their back edge has an upward slope that produces continuous cutting and suction action.
The high lift blades are designed to be used to cut side discharges. They feature sharp upward turns on the back. This type of blade requires more power from the engine to function well. It is a bit more expensive in terms of fuel, however it is ideal for grasses with thicker tufts which are hard to cut with standard blades.
Material
The blades of lawn mowers are typically made of an extremely durable steel. It is also made from iron or other metals. Steel is the most popular metal for mower blades because it provides toughness and durability. It is heated to make the steel harder. This is known as tempering. It enhances the durability, toughness as well as resistance to corrosion.
It is more beneficial to make use of high carbon steel for cutting over low carbon steel as it’s more durable. It is able to withstand the impact of rocks, tree stumps and other objects that could hit the blade without breaking it.
In order to maintain the blade of a lawnmower, it is best to keep it sharp and to use it often. The blade must also be balanced. It is possible to do this by inserting a tiny nail into the board, and then using a file over it to adjust the nail until it is in the middle of the blade.
Sharpness
The quality of your blades depends on many factors like how much you use it and the dimensions of your lawn. Large lawns that are brimming with trees, rocks and pebbles will require frequent sharpening. A dull blade wears out faster if you use it regularly.
A sharp cutting edge is required for a neat and aesthetically pleasing cut. A sharpening blade is a great tool to achieve this. It is similar to an industrial bench grinding machine but it’s much smaller and less expensive.
It is crucial to regularly balance the blade especially after sharpening. Sharpening the blade can cause it to become unbalanced as it removes more metal from one side than the other. To check the balance, put the blade on a nail through its bolt hole and see if it looks even. If one end tilts higher than one, the blade needs to be filed further to ensure it is balanced.
Maintenance
When you are sharpening the mower blade, make use of a tool that works similar to a drill bit, but using a stone that is designed to hug the edge of the blade leaving the least amount of room for errors. This tool is more efficient and more accurate than hand-filing. Verify the balance of the blade by placing it on an anchor through the hole. If the blade isn’t properly balanced, you’ll have to file it more.
To avoid an engine starting up when you work on a blade, switch off the engine and take out the spark plug cable. Block the blade in order to hold it in place while loosening the bolt fastening it with the help of a ratchet or wrench. After reinstalling the blade remember the side that is marked downward to ensure that it is placed in the correct position. Spray WD-40 or a similar lubricant on the bolt for mounting prior to tightening.
