Lawn mower is a tool for cutting grass at an even height. It uses a sharp blade which cuts the grass by being able to rotate at a quick speed by a motor.

How to use an angle grinder to sharpen lawn mower blade
1. Removing the mower blade: At first, you have to remove lawn mower blade from the mower. In order to do so, at first you need to disconnect all the power supply of the tool for being safe. Prevent the motor from accidental starting by removing the plug wire from the spark plug. For being sure, you can tie the plug wire back so that it can’t make a connection with the spark plug again. Wear gloves and eye protector for extra security.
After ensuring that all the power source and spark plug are disconnected, you have to turn the mower on its side. The question is- on which side? Turing the mower on its side may cause the engine oil to enter the air filter and/or carburetor. The construction of the mower allows it to do so. So you need to turn the mower so that the carburetor and air filter face up. If you are not sure about the location of air filter or carburetor, check the user manual to be sure.
After turning the mower, you’ll find the blade situated under the mower. You have to remove that blade for further process. Before removing the blade, I suggest you to mark the outer side of the blade. It will help you to install it correctly after finishing sharpening the blade. Many people don’t mark this and install the blade inversely. As a result, the tool doesn’t cut grass. You can put a mark by simply attaching a tape or spraying a dot using spray paint or simply using paint to put a noticeable mark.
After finished marking, use a wrench or ratchet to take off the bolt and remove the blade. Use something to block the blade, or it will turn at the time of turning the blot and you will not be able to loosen the bolt. There may be a nut holding the blade. However the system is, use proper tools and remove the blade. Just make sure that you have noticed the mechanism so that you can put those in the same place in the same formation at the time of installing. In this process, you will be able to remove lawn mower blade.

Use proper safety gadgets for your security. After being sure that all the preparations are taken, keep the blade firmly with the help of a clamp.

Use the grinder until both cutting sides of the blade become sharp. It won’t take a long time. Pass again and again across the cutting side of the blade to make sure that the whole thing becomes sharp. Check progress again and again.
Take small breaks when you are sharpening the tool. The friction produces heat which might melt the blade. So take small breaks and use water if needed to keep the blade cool.
At the time of using angle grinder as mower blade sharpener, don’t apply much pressure. If you apply pressure more than needed, you’ll find that the edge will be grinded off more than necessary. Again, much pressure will produce much heat.
