How to Remove Riding Lawn Mower Blades?
The first thing any veteran will have in his arsenal is safety precautions. The maintenance work of dangerous equipment like riding lawn mowers or equipment of any kind requires proper safety measures.

And before removing the blade, make sure to get yourself a pair of thick gardening safety gloves to protect yourself from unnecessary bruises and to help you with the projects.
Preparing Your Lawnmower
You should start by taking your lawnmower to the area you choose beforehand and putting it on a hard and flat surface.

It is often very tough to get access to the blades with the little gap between the body of the mower and the lower surface.
So you could be wondering how to lift the riding mower to change blades. To do that, you will need to lift the lawnmower with the aid of some equipment and access the bottom part of the lawnmower. You can do this by using regular car jack stands, or levers.
If you don’t have access to these tools, you can take a thick log, wood, or other hard object and put it underneath the machine. This will ensure greater access to the blades.

You may be starting to understand now that you can never be too safe when it comes to maintaining a riding lawnmower.
The blades underneath are connected to rotatory motors. So even when the machine is turned off, the blade can move or rotate easily with the slightest force.
In order to make sure that the blades make zero movements, it is advised to push a barrier of timber between them. This will restrict the blades from moving.

Pro tip: Make sure to put all the screws, nuts, and bolts in a specific place. This ensures you find them again when you need the blades to join the machine belt.

With the aid of WD-40, sandpaper, and a piece of cloth, you can remove all the rust on your blades. Here is how to do it:
- Spray the WD-40 on the parts of the blade that are rusty.
- Use 180- grit sandpaper on an orbital sander and sand smoothly on the applied parts. This will get rid of almost 95% of the rust.
- Use your hand carefully to sand the blade in tight angles where the orbital sander cannot reach.
- Make sure not to sand along the edges of the blade. Because instead of improving the condition of your blades, this will ruin them further. Always make sure to stay away from the sharp edges.
- After the sanding, wipe the blades with a clean cloth.
- Repeat the steps for other blades affected by rust.
