How to Sharpen your Own Mower Blades
If you’ve started to notice your lawn mower is tearing your grass rather than cutting it, it might be time to get the blades sharpened. There are a couple ways you can do this, depending on how skilled you are with tools or how much money you want to spend on the job.
If you aren’t the Do It Yourself type, you’ll want to take your mower into a shop that sharpen blades. This will cost you some money but you won’t have to worry about messing up.
If you’re the kind of person that’s handy with tools, however, you might want to spend the time sharpening your blades yourself. It’s fairly easy to sharpen lawnmower blades, depending on the type of mower you have.
There are basically three types of mowers; the old style manual push mower, the motorized push mower, and the riding lawn mower. The manual push mowers are easy. You only need a file and a way to keep the blades straight to sharpen them.
The motorized push mower is a bit more difficult as you have to remove the blade to sharpen it. To do this, you need to prop the deck up and use either a wrench or socket to get the nut off to remove the blade.
Once off, you can place the blade in a vice, and either use a file or grinder to sharpen the blade. Try to sharpen the blade at a 45 degree angle and follow the guide on the blade where it was sharpened by the factory.
With a riding mower, you have to do the same thing to take the blade off as you did with the push mower. You might have two, or even three, blades on a riding mower, however. You have to keep an eye on their balance while you’re sharpening the blades. You can do this with a balancer that you can buy from a shop, or place a nail horizontally in the wall and place the blade on it with the nail coming through the shaft hole of the blade.
If it’s balanced well, you can place it on the mower again. Remember to always wear safety glasses when sharpening mower blades.
