How to Start a Lawn Mower with Broken Pull Cord
If your lawn mower has a broken pull cord, it can feel frustrating when you want to start mowing. Fortunately, there are several ways to get your mower running without relying on the traditional pull cord. This guide will walk you through step-by-step methods to start your lawn mower when the pull cord is no longer working effectively.
Understanding Why a Pull Cord Breaks
Before diving into solutions, it’s helpful to know why the pull cord might break. Common reasons include wear and tear, old age, or improper use. The cord may fray, snap, or become detached from the recoil starter.
Knowing these causes can help you decide whether to repair the cord or use alternative starting methods. Sometimes, replacing or fixing the pull cord is a simple task, but in other cases, bypassing it might be more practical.
Safety Precautions Before Attempting to Start Without the Pull Cord
Always prioritize safety when working with lawn mowers. Disconnect the spark plug wire to prevent accidental starting. Wear protective gloves and goggles, especially when handling internal parts or using tools.
Ensure the mower is on a flat surface and the area around you is clear of debris or obstacles. Double-check all safety features and make sure the blades are disengaged if possible.
Assessing Your Lawn Mower’s Type and Starting Mechanism
Different mower models have varying starting mechanisms. Most push mowers rely on a recoil starter with a pull cord, while some riding mowers or professional models may have electric start or alternative systems.
Understanding your mower’s type helps determine which method to use. Look for model details and manual instructions if available.
Method 1: Using an Electric or External Start Method
Replacing the Pull Cord with an Electric Starter
If your mower has an electric start feature, try using it. Connect the battery or power source according to the manufacturer’s instructions. Ensure the battery is charged and properly installed.
If your mower does not have an electric start but is compatible with an external battery kit, consider installing one for future use. This method avoids the need for a pull cord entirely.
Using a Jump Starter or Portable Battery Pack
A portable jump starter can be used if your mower has a 12-volt system. Connect the jump pack following safety procedures and turn on the power. Use the start button or switch to crank the engine.
Ensure your mower’s engine is compatible with external power sources before attempting this method.
Method 2: Manually Bypassing the Pull Cord with a Rope or Cord
Tools Needed
- Strong nylon or polypropylene rope
- Tools to access the recoil starter (screwdriver, pliers)
- Optional: a friend to help
Steps to Follow
- Disconnect the spark plug wire for safety.
- Remove the recoil starter cover using appropriate tools.
- Locate the internal pulley and the broken pull cord.
- Attach the new rope securely to the pulley, making sure it is firmly tied and long enough to pull comfortably.
- Reassemble the cover carefully.
- Hold the mower steady and pull the new rope briskly to turn the engine over.
This method mimics the pull cord’s function, and with patience, can start the engine reliably.
Method 3: Using a Compression or External Starting Device
Compression-Based Tools
Some specialized starting tools use compression to turn the engine over. These are generally used by professionals but can be helpful for stubborn engines.
Portable Electric Starters
Commercial portable electric starters can be attached to the spark plug or other engine parts. Follow the device instructions for safe and effective use.
Preparing the Engine for Starting
Before trying to start your mower, ensure there is fresh fuel in the tank and the choke is set correctly. Check the oil level to make sure the engine is well-lubricated.
Clear the area of any debris and make sure no children or pets are nearby during testing.
Steps to Increase Success Rate
- Apply a small amount of engine oil or lubricant to the cylinder if the engine has been dormant for a while.
- Use a manual compression release if available to reduce resistance during startup.
- Attempt multiple pulls or cranks with your alternative method to build momentum.
Additional Tips for Fixing or Replacing the Pull Cord
If you prefer to repair your pull cord for long-term use, consider purchasing a replacement recoil starter kit. Replacing or repairing the cord is typically straightforward and cost-effective.
Follow the manufacturer’s instructions carefully, and consult online tutorials if necessary. Regular maintenance can prevent future issues with the pull cord.
When to Seek Professional Help
If your attempts to start the mower without the pull cord are unsuccessful or if internal engine parts seem damaged, it’s best to consult a professional. A technician can diagnose and repair the recoil starter or other internal components safely.
Getting professional assistance ensures your mower remains in good condition and avoids further damage.
Maintaining Your Lawn Mower After Starting
Once you get your mower running, perform routine maintenance. Clean the blades, change the oil, and inspect the spark plug regularly. Proper upkeep can extend your mower’s lifespan and reduce the chance of future starting issues.
Keep the recoil starter and pull cord in good condition by cleaning and lubricating parts periodically. Proper storage during off-seasons also helps prevent damage and corrosion.
In summary, starting a lawn mower with a broken pull cord involves assessing your mower’s setup, choosing the appropriate alternative method, and taking safety precautions. With patience and the right tools, you can get your mower running again without needing to replace the pull cord immediately.

Frequently Asked Questions
Can I start my lawn mower by manually rotating the engine?
Yes, you can try to start your lawn mower by manually rotating the engine. Use a wrench or a similar tool to turn the blade pulley or the engine pulley. If the engine turns over easily, you can attempt to pull the starter rope again or use an alternative starting method. This technique can sometimes bypass the broken pull cord and help diagnose if the engine itself is functioning properly.
How can I use an alternative starting method if the pull cord is broken?
One effective method is to access the spark plug and connect it to the spark plug wire. Then, use a remote starter switch or a pair of pliers to touch the spark plug to the engine block while turning the engine manually or using a second person to pull the starter handle. This method allows you to generate the spark needed to start the engine without relying on the pull cord.
What tools are helpful to start a lawn mower with a broken pull cord?
Having a few basic tools can make the process easier. A pair of pliers or a wrench helps to turn the engine manually. A spark plug socket or a screwdriver might be needed to remove the spark plug. An extra spark plug wire or a remote starter switch can assist in igniting the engine. Always ensure the mower is on a flat surface and the spark plug is removed before attempting manual start methods.
Is it possible to start my lawn mower by pushing it downhill?
In some cases, yes. If your mower has a recoil or push-start capability, positioning it on a slight downhill slope can provide enough momentum to turn the engine over. Once the engine begins to turn, you might be able to start it using an alternative method like the spark plug connection. Always ensure the area is clear of obstacles and debris before attempting this method.
Should I consider repairing the pull cord before trying these methods?
Yes, repairing or replacing the pull cord can be a straightforward and cost-effective fix that restores the usual starting method. This can save you time and effort in the long run.
