Garden Tools How to maintain a lawnmower At least once a year there are some simple things to do to make sure your lawn mower runs well and lasts longer.

Project Overview

Your lawn mower is an important gardening tool, so it’s worth taking the time to maintain it. At least once a year there are some simple things to do to make sure your lawn mower runs well and lasts longer. Continue to step-by-step instructions

Step by Step Instructions

1 Safety first
2 Clean the mower
3 Apply lubricant
4 Check the spark plug
5 Check the air filter
6 Clean the catcher
7 Clean and check underneath the mower
8 Check the oil
9 Ready to go
  • Step 1. Safety first

    Before you start any maintenance work on your lawn mower, disconnect the spark plug and make sure the throttle is in the off position. The mower is now safe to work on. Only carry out maintenance on the mower when the engine is cold.
  • Step 2. Clean the mower

    Use the rags and the soft brushes to clean the outside of the mower to remove any dirt, grime and grass that has built up.
  • Step 3. Apply lubricant

    Once you have cleaned the outside of the mower it’s time to apply some lubricant. Spray WD40 onto the wheels, the throttle cable and the height adjuster. Use the rag to wipe away any excess WD40.
  • Step 4. Check the spark plug

    If you have a four-stroke mower, it’s worth checking the spark plug. If you have a two-stroke replacing it can give your mower a new lease of life. Use the socket set to remove the spark plug. If it doesn’t need replacing, clean it with the wire brush. When replacing the spark plug, screw it in with your fingers as far as you can, so that you don’t cross-thread it. Then tighten it with the socket. Be careful not to overtighten it.
  • Step 5. Check the air filter

    Remove the cover from over the air filter. If it’s not too dirty, give it a tap on the bench and a clean with a brush. If it is dirty, it’s well worth replacing it.
  • Step 6. Clean the catcher

    Remove the catcher from the mower. If it’s very dirty you might need to give it a thorough hosing out. If it’s not too bad, clean it out with the brushes.
  • Step 7. Clean and check underneath the mower

    It’s not a good idea to tip your lawn mower upside down, so just lean it back so you can clean and check underneath. Use the brushes to remove the grass. It’s especially important to do this if you have a steel mower because a build-up of grass can cause rust. Inspect the blades to make sure they’re not too badly damaged. If they are, you will need to replace them. Sharp blades cut grass well and keep it healthy. Wear the safety gloves when working around the blades.
  • Step 8. Check the oil

    If you have a four-stroke mower, check the oil. Remove the cap and check the oil level on the dipstick. If the oil level is low, top it up. If the oil is dark and dirty it will need draining and replacing. Another handy tip is to only add petrol to the mower before you use it, that way it won’t go stale.
  • Step 9. Ready to go

    And there you have it, some simple ways to maintain your lawn mower. If you can carry out this maintenance at least once a year, your mower should run long and strong.
