Have you ever found yourself in a situation where your lawn mower just won’t stop running? You’ve tried everything and nothing seems to work. It can be frustrating and even dangerous if you don’t know how to safely shut it down. So, what are the proper steps to turn off a stubborn lawn mower?
Causes of a Lawn Mower Not Turning Off
When your lawn mower won’t turn off, it can be frustrating and concerning. Understanding the potential causes can help you troubleshoot the issue and find a solution. Here are some common reasons why a lawn mower may not turn off:
- A switch stop that doesn’t make contact: If the switch stop fails to make contact with the control bracket, the engine may continue running.
- A faulty ignition switch: A malfunctioning ignition switch can prevent the mower from shutting down properly.
- Faulty wiring: Damaged or faulty wiring can disrupt the electrical circuit and prevent the mower from turning off.
- A malfunctioning control cable: A control cable that is stuck or not functioning correctly can keep the engine running.

These issues can occur in both walk-behind mowers and ride-on models. It’s important to be mindful of these potential causes and take the necessary steps to address them. In the next sections, we will explore various methods to turn off a lawn mower that won’t stop running, providing you with the knowledge to troubleshoot and resolve the issue.
Remember: Safety should always be a top priority when working with lawn mowers. Before attempting any repairs, ensure the mower is turned off and disconnected from the power source or the spark plug wire is disconnected. Refer to your mower’s user manual for specific instructions.
Using the Kill Switch
Most modern lawn mowers are equipped with a kill switch, which is designed to quickly shut off the engine in an emergency. Using the kill switch is often the easiest and fastest way to turn off a lawn mower that won’t stop.
To utilize the kill switch:
- Locate the kill switch on your mower.
- Move the kill switch to the off position.
This should immediately stop the engine.
Using the kill switch is a convenient method to quickly and safely shut down your lawn mower, ensuring the engine stops running without further complications.
For reference:
“The kill switch is a lifesaver when it comes to stopping a lawn mower that won’t turn off. It’s like hitting the emergency brake in a car – instant and effective!”

With the kill switch easily accessible, you can swiftly regain control over your lawn mower’s operation, allowing for a safer and more efficient mowing experience.
Connecting the Switch Stop Tab
If your lawn mower doesn’t have a kill switch or the kill switch isn’t working, you can try connecting the switch stop tab to the control bracket. Consult your mower’s user manual to locate the switch stop. Carefully open the engine cover and use a screwdriver or insulated pliers to bend the switch’s tab downwards. When the tab makes contact with the bracket, the engine should stop.
In some lawn mowers, the switch stop tab serves as an alternative method to turn off the engine. By connecting the tab to the control bracket, you create a direct connection that interrupts the electrical circuit, effectively shutting down the mower.
To perform this action safely, it’s important to follow the steps carefully. Begin by locating the switch stop tab, which is typically located near the engine or control lever. Once you’ve found the tab, consult your mower’s user manual for any specific instructions.
Next, open the engine cover to access the inner workings of the mower. This may involve removing screws or latches, so be sure to have the necessary tools on hand. Take caution not to damage any components while opening the cover.
Once the engine is exposed, use a screwdriver or insulated pliers to carefully bend the switch’s tab downwards. The goal is to create a connection between the tab and the control bracket. When the tab makes contact with the bracket, it completes the circuit, causing the engine to stop running.
After connecting the switch stop tab, you can close the engine cover and ensure it is securely fastened. Give the mower a test by starting the engine and then using the newly connected switch stop tab to turn it off. If the engine shuts down smoothly, you have successfully used the switch stop tab to stop your lawn mower.
Keep in mind that not all lawn mowers have a switch stop tab or an accessible control bracket. If this method doesn’t apply to your mower or doesn’t work, consider trying other techniques mentioned in this article to turn off your lawn mower safely.
Disconnecting the Spark Plug
If your lawn mower doesn’t feature a kill switch or connecting the switch stop tab doesn’t work, you can manually disconnect the spark plug wire to shut off the engine. This should only be done using insulated pliers or a similar tool to avoid any risk of shock.
To disconnect the spark plug wire:
- Ensure the lawn mower is turned off and the engine is cool.
- Locate the spark plug, which is usually positioned near the engine.
- Carefully grip the spark plug wire with insulated pliers, ensuring a firm hold.
- Gently pull the wire away from the spark plug, breaking the connection.
Note: It’s important to disconnect the spark plug wire, not the spark plug itself. Removing the spark plug entirely may cause fuel to ignite if the engine is still running.
By disconnecting the spark plug wire, you interrupt the ignition and stop the engine from running. This method is effective in emergency situations when other options are unavailable or ineffective.
| Pros | Cons |
|---|---|
| Simple and effective | Requires access to spark plug and insulated pliers |
| Can be done quickly | May cause accidental shocks if not performed carefully |
| No additional tools or parts needed | Doesn’t address the root cause of the issue |
Applying a Full Choke
When a lawn mower won’t shut off, applying a full choke is another method you can try to bring the engine to a stop. This involves restricting the airflow to the engine, causing it to stall. If your mower has a manual choke, follow the steps below:
- Remove the air filter cover and air filter from the mower.
- Use a clean cloth to cover the carburetor and restrict the airflow.
By limiting the air supply, you are effectively cutting off the engine’s source of oxygen, causing it to cease running. However, it’s important to exercise caution when using this method as it can potentially flood the engine with gas. If this occurs, allow the engine to dry out before attempting to start the mower again.
Below is a helpful visual representation of the process:
| Pros | Cons |

| Relatively simple method | Potential engine flooding |
Using a full choke can be an effective way to stop a lawn mower that won’t shut off, but it’s essential to assess the situation and follow the appropriate steps based on your mower’s specific features. If this method doesn’t work or you encounter any difficulties, refer to the other solutions outlined in this article to safely and properly turn off your lawn mower.
Switching Off the Gas
If your lawn mower won’t stop running, one effective method to shut it down is by turning off the gas. By cutting off the fuel supply to the carburetor, the engine will eventually come to a stop. Please note that the engine may not shut off immediately due to the remaining fuel that needs to be burnt.
Alternatively, you can also try pinching the gas line with pliers to stop the fuel flow and halt the engine’s operation. This method provides a quick and efficient way to bring your lawn mower to a stop.
By employing these techniques, you can regain control over a lawn mower that won’t stop running and ensure a safe and smooth shutdown.
Disconnecting the Power
When it comes to electric lawn mowers, disconnecting the power source is the key to shutting off the mower. By simply disconnecting the power cord, you can stop the engine and ensure the mower is safely turned off. Carefully grasp the cord and gently pull it out of the power outlet, making sure not to damage the plug or socket in the process. This method is quick and effective, allowing you to regain control of your mower.
If you own a battery-powered mower, the process is just as easy. To turn off the engine, disconnect or remove the battery from its compartment. This action eliminates the power source and effectively stops the mower’s operation. It’s important to handle the battery with care and follow the manufacturer’s instructions for proper detachment.
By disconnecting the power, whether it’s through the power cord or by removing the battery, you can ensure that the electric lawn mower won’t turn on unintentionally and guarantee a safe environment for maintenance or storage.
Disconnecting the power cord or removing the battery stops the engine of an electric lawn mower.
