How to Change an Electric Mower Blade

On your lawnmower, aside from the motor the most important part is the blade, and like any kind of blade over time they will become blunt. When this happens you will want to replace the existing blade and change it for a new, sharp blade.

When blunt, if you continue to cut your lawn you could end up with bald patches due to the grass being ripped out of the soil instead of it being trimmed. If you are noticing that your grass is not being cut correctly then a replacement blade will most likely be required.

Metal Blades

If your lawnmower has metal blades, following the steps below will help you change a damaged or dulled blade safely and efficiently.

What You Will Need:

Step 1 - Safety Advice

Safety first: always unplug electric mowers before repairing, and keep the mains plug beside you so no one inadvertently reconnects the power supply. Wear safety gloves while working with blades.

Step 2 - Removing the Old Blade

Step 3 - Aligning the Blade

Metal blade components

Taking your new blade, place it onto the spacers, ensure any pegs are located in the appropriate holes on the blade.

Step 4 - Securing the New Blade

With the blade in place, put the bolt through the centre hole in the blade. Once in place turning the bolt clockwise will tighten the bolt locking the blade. Tighten using your Flymo spanner.

Following the steps above will help you safely and correctly replace the blunt blade on your lawnmower.

Plastic Blades
