1.) Raise The Mower Deck To Uncover The Blade:

Keep in mind that you are not bending the lawnmower in such a manner that oil dribbles across the engine, the lawn, and yourself by paying particular attention to the carburetor and the oil container. The best approach to accomplish this is to turn the mower back toward the handle and hold it up with a load or with the assistance of a person. It isn’t always applicable for all lawnmowers, so use your time wisely and, if required, examine the owner’s instructions.

If any oil or gas interacts with the spark plug, it’s advisable to be cautious and avoid a short-out or electrical flare-up. It shouldn’t be an issue if you handle the lawnmower correctly, but it’s always better to be careful.

3.) Drag The Blade Mounting Bolt:

Unscrew the mounting with a socket wrench of the correct length, keeping the blade from rotating with your different side. Take care not to misplace any screws or bolts that can be utilized to keep the blade in position.

When you’re replacing the blade, keep an eye on its location. The replacement one will be mounted in the same arrangement as the old one, with the pointed end of the blade traveling counter-clockwise as the system rotates. However, that might not be the case on all lawnmowers, so pay much attention to how this blade is attached and replace it appropriately.

4.) Buy Replacement Blades:

Turn the lawnmower back to check the blade, or ask a hardware shop employee about the sort of blade that will work with your mower. If you have one, look through the owner’s guide.

Furthermore, if the previous blades appear in a proper shape, you can save those and get them cleaned. If the blades are old, with shards or bits of metal missing, it’s time to replace them.

5.) Place The New Blade In The Correct Direction:

The majority of blades have a particular or standard fitting. When installing the new blade, ensure it’s the same size as the previous one and that the distance from the lawn mower deck is equal.

It’s also a good idea to block the blade from rotating when reinstalling it with a little bit of wood.

Try to avoid motor disturbance. Wait for an hour or 30 minutes for the oil to flow to the motor. Before using the oil, keep in mind, it is within the recommended parameters.

7.) Reload The Gas Tank And Do A Quick Check Before Trimming:
