1. Unplug Power Source

First things first. Unplug the power source because if you don’t do that your lawn mower start while you’re trying to remove the blade out of it. We also recommend that you disconnect the spark plug, along with the power source. To know how to do this, you can read the user manual that came along with the mower.

2. Turn Mower on its Side

This doesn’t mean that you can turn the mower upside down – also, don’t try to turn it in a slapdash manner because doing so will cause the oil to flow right into the air filter and carburetor. You should do it in a way that the carburetor faces up. If you are not sure about where any part of your mower is located, contact the manufacturer. For supplementary protection, you can use the mower so it runs out of gas or you can also try pouring the oil into a separate container.

3. Mark the Blade

Before removing the blade, marking the blade with a pen or spray is suggestion because, at the time of putting it back, you may not know which side is up or which one is down. To avoid this dilemma, you should mark the blade. If you don’t have a spray and the pen doesn’t work on the surface of the blade (because it is made of steel), perhaps, you would want to try putting some tape on it. Best Rear Engine Riding Mowers

4. Open the Fastening Bolt

Warning! Before you open the fastening bolt, you will need to block the blade so as to make it steady because if you don’t block it, it will move along with the wrench or ratchet. We suggest that you either use a sturdy block of wood between the deck of the mower and the blade. But if you already have a vise or clamp, it is going to do wonders – I don’t think you will need anything else to do this.

5. Clean Grass Clippings & Rust

If you have been taking the best use of the mower in a frequent manner, it is possible that it will be dirty with the grass clippings, dust, and so forth. Once the blade has been taken out, you can clean the area behind where the blade was attached. This is necessary to have a longer life for your mower and to keep it run as smoothly as possible – i.e. without any problem at all.
