Figuring out how to dispose of a lawn mower can feel like a hassle, but it is actually a straightforward process once you know the rules. A lawn mower disposal requires draining fluids and separating metal parts before recycling.
You cannot just toss a whole mower into your regular trash can in most areas. The combination of gasoline, oil, and heavy metal makes it a hazardous item that needs specific handling.
In this guide, you will learn the exact steps to prep your mower, the best places to take it, and how to do it without breaking any local laws. We will cover both push mowers and riding mowers, so you are covered no matter what type you own.
Why You Cannot Throw A Lawn Mower In The Trash
Most municipal waste facilities have strict rules against putting whole mowers in the garbage. The primary reason is the leftover fuel and oil inside the engine.
These fluids can leak out and contaminate the soil and groundwater at landfills. Even if you think the tank is empty, residual fuel sits in the carburetor and fuel lines.
Another reason is the sheer weight and bulk. A standard push mower can weigh 80 pounds, and a riding mower weighs several hundred pounds. This damages standard garbage truck compactors.
Finally, the metal body and engine block are highly recyclable. Throwing them away wastes valuable resources that could be repurposed for new steel products.
How To Dispose Of A Lawn Mower
This is the core section where we break down the entire process into clear, actionable steps. Follow these in order to avoid fines and to keep your local environment safe.
Step 1: Drain All Fluids Completely
This is the most critical step. You must remove the gasoline and the engine oil before any disposal method.
- Run the mower until it runs out of gas naturally. This clears the fuel lines.
- If it will not start, use a siphon pump to remove gas from the tank.
- Place a drain pan under the oil plug. Remove the plug and let the oil drain completely.
- Dispose of the oil and gas at a local hazardous waste collection center. Never pour them down a drain.
Step 2: Remove The Battery (If Applicable)
Electric start mowers and riding mowers have lead-acid batteries. These are highly toxic and must be removed.
Disconnect the negative terminal first, then the positive terminal. Lift the battery out carefully. Take it to an auto parts store or battery retailer for recycling. Most stores accept them for free.
Step 3: Remove The Spark Plug
Taking out the spark plug prevents accidental starting. This is a safety measure for anyone who handles the mower later.
Use a spark plug socket to unscrew it. You can throw the old plug in the trash since it is just ceramic and metal. It is small enough not to cause issues.
Step 4: Separate The Parts
If you have the tools, disassemble the mower into its core components. This makes recycling much easier.
- Remove the plastic grass catcher or bag.
- Take off the plastic wheels and deck covers.
- Separate the steel deck from the engine block.
- Keep the steel handle separate from the plastic grips.
Separating these materials means the scrapyard can process them faster. You might even get a small cash payout for the scrap metal.
Step 5: Check With Your Local Waste Management
Call your city or county waste department. Ask about “bulk item pickup” or “household hazardous waste” schedules.
Some areas offer curbside pickup for large metal items on specific days. Others require you to schedule a special appointment. Never assume the rules; always verify with a phone call or a quick website check.
Options For Disposal And Recycling
You have several choices when it comes to actually getting rid of the mower. Each option has its own pros and cons depending on your time and effort.
Option 1: Scrap Metal Recycling Center
This is often the best choice for a non-running mower. Scrap yards pay by the pound for steel, aluminum, and copper.
Call ahead to confirm they accept whole mowers or if you need to disassemble it first. Some yards will take the whole unit after you have drained the fluids. They will weigh it and give you cash on the spot.
This option keeps the metal in the recycling loop. It also clears your garage immediately without waiting for a pickup appointment.
Option 2: Municipal Curbside Pickup
Many cities have a “bulk trash” day once or twice a year. On this day, you can place large items at the curb.
You must still drain the fluids and remove the battery. If you leave gas in the tank, the collection crew will refuse to take it. Place the mower upside down or with the gas cap open to show it is empty.
Check your city’s website for the exact date. Mark it on your calendar so you do not miss the window.
Option 3: Retailer Take-Back Programs
Some big box hardware stores offer recycling programs for outdoor power equipment. Home Depot and Lowe’s have had seasonal events in the past.
These events are not always available year-round. Call your local store and ask if they have a drop-off bin for small engines. If they do, they usually handle the disposal for you.
This is the most convenient option if you are buying a new mower from them. You can often bring the old one in on the same trip.
Option 4: Sell Or Donate It
If the mower still runs, do not recycle it. Someone else can use it. List it on Facebook Marketplace or Craigslist for a low price.
You can also donate it to a local charity, high school shop class, or community garden. Many non-profits will pick it up for free if it is in working condition.
This is the most environmentally friendly option because it extends the life of the product. It also puts a little money in your pocket.
How To Dispose Of A Riding Lawn Mower
Riding mowers are heavier and more complex. They require extra steps due to the larger engine and the presence of a transmission.
Drain The Fuel Tank And Oil
Use a siphon to remove all gasoline from the tank. Then run the engine briefly to burn fuel from the carburetor. Drain the engine oil the same way you would on a car.
The transmission fluid also needs to be drained. Check the owner’s manual for the drain plug location. Collect this fluid in a separate container and label it clearly.
Remove The Tires And Battery
The tires are often rubber on steel rims. You can recycle the rims as scrap metal, but the rubber tires need to go to a tire recycling center. Many landfills have a separate tire disposal fee.
Remove the battery and take it to an auto parts store. The larger battery is worth a few dollars in core charge if you trade it in.
Cut The Frame If Needed
Some scrapyards require the mower to be cut into smaller pieces. Use an angle grinder to cut the frame in half. This makes it easier to transport and process.
If you do not have the tools, call a local junk removal service. They will handle the cutting and hauling for a fee.
Environmental Impact Of Improper Disposal
Dumping a mower in the woods or leaving it on the curb without draining fluids has serious consequences. One gallon of gasoline can contaminate 750,000 gallons of water.
Oil that seeps into the ground can poison the soil for years. This affects local plant life and can seep into groundwater wells. It is not just an eyesore; it is a public health risk.
Recycling your mower reduces the need for new iron ore mining. It also cuts down on the energy required to smelt new steel. You are doing your part to conserve resources by taking it to the right facility.
Costs Associated With Disposal
Most disposal methods are free or very cheap. Scrap yards often pay you a small amount for the metal weight. A typical push mower yields about $5 to $10 in scrap steel.
If you use a junk removal service, expect to pay between $50 and $150 depending on the size and weight. This fee covers their labor, transportation, and the recycling drop-off fees.
Some municipalities charge a small fee for hazardous waste drop-off. This is usually under $10. Check your local facility’s fee schedule before you load the mower into your truck.
Frequently Asked Questions
Can I Put A Lawn Mower In A Dumpster?
Yes, you can put a drained mower in a rented dumpster. However, you must remove the gas tank and drain all oil first. Dumpster companies will fine you if they find leaking fluids. The weight is also a factor, so check the weight limit of your dumpster rental.
Does Home Depot Take Old Lawn Mowers?
Home Depot does not have a year-round program for mower recycling. They occasionally run seasonal events for small appliances. Call your local store to ask if they have a current promotion. Otherwise, you will need to use a scrap yard or municipal pickup.
How Much Gas Can I Leave In A Mower For Disposal?
You should leave zero gas in the tank. Even a small amount is a fire hazard during transport. Run the mower dry or siphon every drop out. The carburetor should also be empty. If you cannot drain it, take the entire mower to a hazardous waste facility.
Is It Worth Scrapping A Lawn Mower For Metal?
Yes, it is worth it for the environmental benefit. Financially, you will only get a few dollars for a push mower. A riding mower might fetch $30 to $50 in scrap. The real value is in keeping the metal out of the landfill and avoiding disposal fines.
Can I Throw A Lawn Mower In The Regular Trash?
No, you cannot throw a whole mower in the regular trash. Most waste haulers will not pick it up. If you leave it at the curb, you risk a fine from your city. Always use a designated recycling or scrap metal drop-off point.
Final Checklist Before Disposal
Before you haul the mower anywhere, run through this quick checklist to avoid rejection at the facility.
- Fuel tank is empty and dry.
- Engine oil is drained into a sealed container.
- Battery is removed and set aside for recycling.
- Spark plug is removed.
- Grass and debris are cleaned off the deck.
- You have confirmed the facility accepts mowers.
Taking these steps ensures a smooth drop-off. It also protects the workers at the recycling center from dangerous spills or fires.
Now you know exactly how to handle this task. Gather your tools, drain those fluids, and get that old mower out of your shed the right way. Your local environment and your neighbors will thank you for doing it properly.
