One of the most common repairs for a lawn mower is with the blades. Every time you mow your yard, the blades on your mower get a little bit duller. This dullness increases if you accidentally run over small stones or sticks that might be hiding in your grass.
Because of this, your grass will be ripped apart rather than cut evenly, and this can create jagged looking growth and issues with the health of your lawn. With dull blades comes a maintenance routine that you need to perform to keep your mower cutting at peak performance.
The first thing you need to do is determine just what kind of blades you have on your mower. Blades come in two kinds of material; tool steel and carbon steel. Tool steel blades are much more expensive and require a heavy duty grinder in order to sharpen them again.
You will more than likely have to take them to a professional to get them sharpened. This will cost you a bit of money, but it’s worth it when you consider the overall health of your grass and the life of your lawn mower.
Carbon steel blades are much easier to maintain and you can usually sharpen them on your own if you have a mountable grinder or a file that you can use. While tool steel blades will stay sharper longer, the ease of being able to sharpen your own carbon steel blades makes the price difference something to consider when purchasing your lawn mower.
There are a few things that you have to remember when sharpening your blades. The first thing is safety. Sharpening a blade can cause small slivers of metal to fly around, so make sure you wear safety glasses at all times when working with metal.
Larger riding mowers have more than one blade on the deck. Because of this, you should either sharpen one at a time or number them so that you can put the same blade back on the same spindle mounting. You should also make sure that the blades are sharpened evenly, as an out of balanced blade can cause damage to your mower and possibly injure you or others standing nearby without any warning.
