Changing a lawn mower blade is a really common maintenance task that you’ll almost certainly have to do at some point in the life time of your petrol mower. If the blade becomes cracked, damaged or bent, then it’s important that the blade is replaced straight away. We advice our customers to check over their blade before every use (or after you’ve cut, when you’re clearing clippings away from the deck). If you spot anything amiss, it’s time to replace your cutter blade.
Changing a lawn mower blade is a easy job, but if you’re not careful and you don’t know what you’re doing, then it can also be quite dangerous. Lawn mowers aren’t toys, and whether you’ve a petrol, battery or electric model, you will need to be sensible when changing blades; we don’t want anyone losing any fingers. This short video is designed to explain how best to change your lawn mower blade to give you a cleaner cut, whilst keeping those hands safe.
- Tip the mower so that the handles are leaning backwards and the front of the mower is in the air
- Remove the spark plug cap (if you’re changing the blade on an electric mower, make sure it’s unplugged, and remove the battery from cordless mowers)
- Put on gloves to protect your hands from the blade. Even though the blade won’t be able to start up the edge is still very sharp so you could easily slip and give yourself a nasty cut
- Use a block to jam the blade
- Undo the blade bolt, and remove from the lawn mower
- Check over the new blade. It should be the same as the one you’re removing. If there are any cracks or damage to the new blade then do not fit it
- Fit the new blade by placing under the deck (some have a locating point to make this really easy) and then screwing the bolt in by hand
- Lock blade in place again with the block, and tighten
- Remove the block and put the mower back down
- Refit the spark plug cap
