mower wont start after winter

Most people that own lawn mowers do not use them through the winter months and so they stow them away somewhere out of sight and whilst this is alright, if they have not taken adequate precautions, they may have trouble starting it after the winter is over.

Condensation gets everywhere and your mower is not immune wherever you may have stowed it. Condensation will occur in the fuel tank and carburetor where the condensed water will mix with the fuel and make it unusable.

Although there are precautions you can take to help ensure this does not happen, it is probably still best to prepare to take longer when undertaking your first lawn mowing task of the summer.

You Will Need:

What you need to do:

  • If your mower is electric, as there is a good chance the battery lost its power through the winter months, ensure you recharge it before the start of summer.
  • If your mower has a 4 stroke gas engine ensure you check the oil before trying to start the mower.
  • Remove the spark plug, clean it with the emery cloth and dry it, also dry the terminal.
  • Siphon off the old fuel and replace it with fresh fuel.
  • Before replacing the spark plug, crank the motor to help dry out the carburetor.
  • Once the mower starts turn off the choke immediately otherwise you may flood the engine and have to start all over again.

Words of caution

When first using your mower after it has not been used for a long period, it is best to keep it at its slowest speed for at least 5 minutes to allow all parts to become fully primed.

The blades of all mowers will become blunt over time and so it is a wise decision to sharpen your blades at the start of the season, although they still may need re-sharpening later as well.

All lawn mowers need to be winterized before storing away for the winter months and often the manual provided with the mower will give full instructions on how exactly to do that. The manual should also be consulted with reference to any safety precautions which should be taken before carrying out maintenance on the mower.

Regardless of what type of lawn mower we may have, all of them are machines and as such are susceptible to the elements and just like a car, if it sits idle for a long period, it may give trouble and the time it gives that trouble is often the time when you need it most. Any lawn mower though is a reliable hard working machine which is probably used most often out of all your yard tools and so deserves a little attention from time to time and certainly prior to be laid up for an extended period.

Once you are ready to start mowing, ensure everything has been replaced tightly including the blades if they were removed for sharpening and of course the spark plug.


If you maintain your mower properly it should last you many years, saving you the expense on having to buy a new one every year or spend money to have it repaired.
