The warm weather has finally arrived, and you’re ready to tackle your overgrown lawn. You grab your brand new lawn mower, pull the cord, and… nothing. Frustration sets in as you realize your shiny new machine isn’t cooperating. Don’t despair! While a non-starting lawn mower can be a real pain, it’s usually a simple issue that can be fixed with a little troubleshooting. This article will guide you through the most common reasons why your new lawn mower won’t start and provide step-by-step solutions to get you back on track to a perfectly manicured lawn.
A quick overview: The most common reasons for a new lawn mower not starting are dead batteries (for electric mowers), lack of fuel, clogged air filters, spark plug issues, and incorrect choke settings. We’ll discuss each of these issues and offer solutions to get your lawn mower running smoothly.
Fuel and Fire: The Basics of Lawn Mower Operation
Before diving into troubleshooting, let’s understand the basic mechanics of a gas-powered lawn mower.
- Fuel: Your lawn mower needs gasoline to run. It’s as simple as that. If you haven’t added fuel, your mower won’t start. The fuel tank is usually located on the side or top of the mower.
- Spark: The spark plug creates a spark that ignites the fuel-air mixture in the engine cylinder. This spark is essential for combustion, and a faulty spark plug can prevent your mower from starting.
- Air: The air filter helps to keep dust and debris out of the engine. A clogged air filter can restrict airflow, making it difficult for the engine to run properly.
Troubleshooting Your Non-Starting Lawn Mower
Now, let’s tackle those common problems and find the solution for your lawn mower’s starting woes.
1. The Fuel Factor: Is There Fuel in the Tank?
This might seem obvious, but you’d be surprised how often the simplest solution is overlooked. Before you start troubleshooting anything else, check the fuel level.
- Step 1: Locate the fuel tank on your lawn mower. It’s usually on the side or top.
- Step 2: Check the fuel level. If the tank is empty, fill it with fresh gasoline.
- Step 3: Use a fuel stabilizer if you won’t be using the mower for a while.
2. Spark Plug Power: Inspecting the Spark Plug
A faulty spark plug can be the culprit behind your mower’s refusal to start.
- Step 1: Locate the spark plug on the engine. It’s usually a small, metal cylinder with a wire attached.
- Step 2: Disconnect the wire from the spark plug.
- Step 3: Use a spark plug wrench to remove the spark plug from the engine.
- Step 4: Inspect the spark plug for signs of wear, corrosion, or fouling (black soot build-up). If the spark plug appears damaged or fouled, replace it with a new one.
- Step 5: Reconnect the wire to the new or cleaned spark plug.
3. Air Filter Blues: Checking for Clogs
A clogged air filter restricts airflow to the engine, making it difficult for the lawn mower to start.
- Step 1: Locate the air filter housing. It’s typically a small box or cylinder attached to the engine.
- Step 2: Remove the air filter housing and inspect the filter element.
- Step 3: If the filter is dirty or clogged, replace it with a new one.
- Step 4: Reinstall the air filter housing.
4. Choke It Up: The Choke’s Role in Starting
The choke helps to enrich the fuel-air mixture in the engine, making it easier to start when cold.
- Step 1: Locate the choke lever. It’s usually a lever or button on the engine or handlebars.
- Step 2: Engage the choke lever before starting the mower.
- Step 3: Once the engine starts, gradually disengage the choke lever. You may need to keep the choke slightly engaged for a few moments until the engine warms up.
5. Electric Mowers: Battery Power Check
If you have an electric lawn mower, a dead battery is the most common reason it won’t start.
- Step 1: Check the battery level indicator on the mower.
- Step 2: If the battery is low, recharge it fully.
- Step 3: Make sure the battery terminals are clean and secure.
- Step 4: If the battery is old or damaged, you may need to replace it.
6. Other Potential Issues
While the above troubleshooting steps address the most common reasons for a lawn mower not starting, there are a few other factors to consider:
- Fuel Line Problems: A clogged or damaged fuel line can prevent fuel from reaching the engine. Inspect the fuel lines for leaks, kinks, or blockages.
- Engine Problems: If you’ve checked everything else and your lawn mower still won’t start, there might be a more serious engine problem. In this case, it’s best to take the mower to a qualified repair shop.
7. Preventing Starting Problems
Here are some tips to help you avoid those frustrating lawn mower starting woes in the future:
- Use Fresh Fuel: Always use fresh gasoline, as old fuel can gum up the engine.
- Regular Maintenance: Perform routine maintenance on your lawn mower, including changing the air filter, cleaning the spark plug, and checking the fuel lines.
- Store Properly: Store your lawn mower in a clean, dry place when not in use.
8. Seeking Professional Help
If you’ve tried all of the above troubleshooting steps and your lawn mower still won’t start, it’s time to call in the professionals. A qualified repair shop can diagnose and fix more complex engine issues.

FAQ
Here are some FAQs about why your new lawnmower may not start:
Q1: I just bought a brand new lawnmower and it won’t start. What should I do?
A: It’s frustrating to buy a brand new lawnmower and have it not work! The first thing to do is check your owner’s manual for troubleshooting tips. Make sure you’re following the correct steps for starting the mower, including filling the tank with the correct type of fuel. If you’re still having trouble, contact the manufacturer or a local repair shop for assistance. They may be able to offer more specific advice or help you determine if there’s a manufacturing defect.
Q2: My lawnmower has fuel in it, but it won’t start. What’s wrong?
A: If you’ve filled the tank, you may have an issue with the fuel lines or carburetor. Check the fuel lines for any kinks or blockages, and make sure they are connected securely. Also, ensure the fuel is fresh – if it’s older than 3 months, it could be contaminated and preventing the engine from starting. If these things seem alright, your carburetor may need to be cleaned or adjusted.
Q3: My lawnmower is making a clicking sound, but won’t start. What’s going on?
A: A clicking sound can indicate a problem with the starter or battery. If you have a battery-powered mower, check the battery’s charge level and make sure the terminals are clean and secure. If you have a gas mower, the starter may be faulty and need to be replaced. It’s also possible the battery is dead if your lawnmower is electric.
Q4: The engine on my lawnmower keeps dying. What could be causing this?
A: An engine that keeps dying could have a few different causes. One possibility is a clogged air filter. The engine needs air to run, and a clogged filter can restrict airflow. Another possibility is a fuel problem, such as a clogged fuel line or a faulty carburetor. If the engine runs for a short time and then dies, it might be a sign of a problem with the fuel system.
Q5: My lawnmower won’t start after sitting over winter. What can I do?
A: After sitting for a long period, your lawnmower may require some maintenance before it starts. First, check the fuel. It’s best to use fresh fuel, as old fuel can gum up the engine. Next, check the spark plug and make sure it’s clean and in good condition. If necessary, replace it. You may also need to clean the carburetor, which can get clogged over time.
Q6: What should I do if the engine is smoking?
A: Smoke from a lawnmower engine can indicate a serious problem. It’s best to stop the engine immediately and avoid running it further. Common causes of smoke include a faulty spark plug, a clogged air filter, or an oil leak. Check these components and address any issues before restarting the engine.
Q7: My lawnmower is making strange noises. What’s wrong?
A: Strange noises coming from your lawnmower could signal a number of issues. It could be something simple like a loose bolt or nut, or something more serious like a worn-out blade or a failing engine part. Inspect the mower carefully and listen closely for the source of the noise. If you can’t pinpoint the problem, it’s best to take it to a qualified repair technician for diagnosis.
