It’s probably wintertime, and you don’t need your gas lawnmower anymore. Or maybe you’re just tired of it and you want a newer model and the old one is taking a large chunk of much needed space in your garage or shed? 

What to do with Your Old Lawnmower?

There are various ways to dispose of a gas lawnmower, but it is important you do it the right way because it is powered by “gas” which is very combustible and therefore extremely dangerous.   Now that you have decided to do away with your old gas lawn mower please note that the option you choose also depends on two things:

  • If it is still in working condition
  • If it is totally damaged

If Your Gas Lawnmower is Still in Good Shape

Place it for Sale

This could actually fetch you a few extra bucks as well as give you that much needed space you require. Before placing it for sale make sure it’s clean, take a few really nice pictures of it and put it on website platforms that allow you to sell off your old stuff such as Decluttr and OfferUp. If you’re lucky, you will get a buyer in a few days, some extra bucks and that free space you need in your shed or garage.

Most gas lawnmower owners prefer to go through this process, so they don’t have to worry about what to do with the lawnmower. If you don’t want to sell your old mower on a website, you can advertise it in a local weekly newspaper or locally to roadside dealers who hopefully will give you a fair price for it.

Give it Away as Charity

While this may sound like a good idea to a lot of people, only try this when you are sure your gas lawnmower is in proper working condition as stated above. By donating it, you could be helping someone else save on the costs involved in purchasing a new lawnmower. Or if you know any school or educational organization that could use it, then you can also donate it to them. By donating it, you don’t have to worry about how to dispose of it.

Dismantle it for Parts

If you plan on purchasing an upgraded model of your old gas lawnmower, it is expected that some parts will be the same since it is from the same manufacturer. If you have the technical-know-how and skills, then you can dismantle the gas lawnmower and separate the parts you know you might need in case the newer model you plan on purchasing needs parts in the future.

Safety First

Before dismantling any gas lawnmower, you first need to make sure that the gas in it is totally emptied. This can actually be done by just leaving the fuel tank open and letting it evaporate, but this isn’t an ideal way to go about it. You should siphon out the gas instead, to siphon out the gas you will need:

  • A siphon hose
  • Protective gloves
  • Safety glasses
  • A tarpaulin sheet
  • Gas ( Department of Transportation) container

Put on your protective gloves and safety glasses. Take the gas lawnmower outside for better ventilation; put it on the top of the tarpaulin, which should be spread already. Remove the gas cap and put the siphon hose into the gas tank and run it to the gas container.

Drain as much gas as you can through this process and leave it open for any residual gas to evaporate. After you have put the gas in a gas container, dispose of it at any hazardous waste agency.

Additionally, if your mower has oil stains you will not be able to give it to the waste facility as is, but will need to clean the oil stains and residue first and then take it as trash.

Disposing of Spare Parts

If you are unable to dispose of the whole lawn mower as a single piece, either because there is no facility that would take it or you would like to make some additional money, you can always sell the mower in parts.

While some components will always go as solid waste, others can be sold even if broken. The only part that you need to be really careful about here are the batteries, because they can be filled with dangerous chemicals and need to be disposed of separately.

Recycle it

There are so many recycling agencies, just find one close to you and have them handle it. Many recycling agencies recycle stuff at no extra charge to you, so it’s a win-win situation. Since you have already done the dismantling process and you have siphoned the gas, it becomes far easier for the recycling agencies to help you out.

Piece by Piece

If the engine of your lawnmower is in good shape, but the outsides are rusted already, dismantle it so that it can be sold for its parts. You can sell the engine and all the other components separately. This can fetch you more cash than expected. There are many people who buy used lawnmower parts because it’s cheaper than getting a new one.

You just have to put it in your local newspaper or on a local online website with the engine size, mower model, and all necessary information that will provide potential buyers with a clear knowledge of what exactly you are offering up for sale. If the parts are small enough to ship, you can offer them on both Ebay and Amazon.

Sell it as Scrap

Most times you are in a hurry to get rid of the gas lawnmower quickly so that a new one can come in, or you need the extra space. This is the fastest option, selling it as scraps. You don’t need to go through the hassle of cleaning it up and advertising it for sale or dismantling it and selling for parts.  All you need to do is to take it to a local junkyard and have them do all the dismantling and give you cash.

The price they offer may fluctuate based on the metal of your mower. For aluminum engines and castings, the pay is usually more than for plain steel. It won’t hurt to check out what your lawnmower is made of. How do you do that? Just get a magnet and place it close to it, if it clings, then it may be steel, and if it doesn’t, it may be metal.


It is important to dispose of your gas lawnmower properly. If you don’t need the extra bucks, selling it as scrap is obviously the ideal option.
