It is better to flip the mower so that the air filter is up and that the gas or oil doesn’t exist or leak into the air filter. Take a socket and a wrench to remove the blade. You will need something to brace the blade.


I generally do this with my foot. Suppose you don’t want to use your foot. You can use a hefty price of scrap wood. Put that wood between your foot and your mower blade. When the mower blades remove, flip it back over to sit on the ground as it should.

II. Rusty Mower Deck- Remove the rust

If you don’t get rid of the rust then there’s no point in doing the job as the whole mower will fall apart at some point so here’s where the Hammerite Kurust comes in.

Step 1. Clean the area- Ensure the area is clean from grass and dust etc and then get at it with a wire brush. This will remove any loose paint and rust and give you a sound surface to work from.

Step 2. Apply the Kurust with an old brush- The Kurust will convert the rusty area into a solid and inert surface. If you want to get geeky then it actually converts iron oxide to stable iron complexes.

Please note you shouldn’t put the brush back into the original pot as that could spoil it, so first off transfer any Kurust you intend to use into a separate pot.

Step 3. Leave it to dry and do it’s magic- It only actually takes 15 minutes so this really is a job you can do all in one go.

III. Hole in a mower deck- Repair the hole

Step 1. Cut out lengths of glass fibre into handy and workable sizes. There’s plenty in the pack so cut a lot as it gets messy later on.

Step 2. Put plastic gloves on (again supplied in the pack)

Step 3. Mix some resin with the hardener. Only make enough you can use in 5 minutes as it will set pretty quickly!

Step 4. Brush the mixed resin onto a strip of glass fibre and then put the strip onto the mower hole, sticky side down. Generously apply more resin to the fibre and stipple the brush so that you can see the fibre glass starting to separate which will indicate that it’s been fully applied.

Step 5. Repeat with the remainder of the strips allowing a slight overlap. These will fully harden in 20 minutes so if you want to apply another layer of fibre glass then you can.
