How to Replace A Pull Cord on A Push Lawn Mower?

18 minutes read

To replace a pull cord on a push lawn mower, you will need to follow these steps:

  1. Safety first: Before starting any work on your lawn mower, make sure it is turned off and remove the spark plug wire to prevent accidental starting.
  2. Remove the old cord: Locate the recoil starter assembly on the mower (usually located on the top of the engine). Unscrew and remove any screws or bolts securing the assembly cover. Once the cover is off, you will see the old pull cord coiled up inside it. Carefully unwind and remove the old cord.
  3. Prepare the new cord: Purchase a replacement pull cord from a hardware store or online, ensuring it is the correct length and thickness for your mower. Cut the new cord to the required length, leaving some extra length to work with.
  4. Attach the new cord: Feed one end of the new cord through the hole in the recoil starter assembly cover from the inside. Tie a knot at the end of the cord to prevent it from coming out. Pull the cord through until the knot is securely seated against the inside of the cover.
  5. Wind the recoil spring: On the inside of the recoil starter assembly, you will find a small pulley with a recoil spring attached. Hold the pulley to prevent it from spinning and wind up the recoil spring in the direction specified on the assembly.
  6. Attach the cord to the pulley: Once the spring is wound, carefully thread the free end of the cord through the eyelet or notch on the pulley. Tie a knot at the end of the cord, ensuring it holds securely.
  7. Reassemble the recoil starter assembly: Slowly release the tension on the pulley, allowing the spring to draw the cord onto it. Gently guide the cord as it winds onto the pulley, making sure it stays in the track. Once the cord is fully wound, reattach the recoil starter assembly cover and secure it with the screws or bolts.
  8. Test the new cord: Give the cord a few gentle pulls to ensure it operates smoothly and retracts properly. If it does not, you may need to repeat the process and adjust the tension on the recoil spring.


Remember to always refer to the manufacturer's instructions for specific guidance on your lawn mower model.

How to maintain and clean the pull cord assembly for extended durability?

To maintain and clean the pull cord assembly for extended durability, you can follow these steps:

  1. Remove any debris: Start by inspecting the pull cord assembly and removing any dirt, dust, or debris that may have accumulated on or around the assembly.
  2. Lubricate the moving parts: Apply a small amount of lubricant (such as silicone spray or chain lubricant) to the moving parts of the pull cord assembly. This will help reduce friction and wear, ensuring smooth operation.
  3. Check and tighten screws or bolts: Inspect the screws or bolts that secure the pull cord assembly to the device it is attached to (e.g., lawnmower, generator). Make sure they are tightened securely to prevent any vibrations or looseness that may damage the assembly.
  4. Inspect the pull cord: Check the pull cord for any signs of wear, fraying, or tearing. If the cord is damaged, it should be replaced with a new one to ensure proper functioning and prevent accidents.
  5. Clean the cord and pulley: If there is any dirt or grime on the cord or pulley, wipe them down with a clean cloth or brush to remove it. You can also use a mild detergent if necessary, but make sure to rinse thoroughly and dry completely afterward.
  6. Protect the pull cord assembly: If the pull cord assembly is exposed to harsh weather conditions or extreme temperatures, consider covering it or providing additional protection to prevent damage and premature wear.


By following these steps regularly, you can maintain and clean the pull cord assembly to ensure extended durability and reliable operation.


How to test the tension of a new pull cord?

To test the tension of a new pull cord, you can follow these steps:

  1. Start by ensuring the equipment attached to the pull cord is in the disengaged or off position. This will help prevent any accidental starting during testing.
  2. Locate the pull cord handle and hold it firmly.
  3. Gently pull the cord outward until you feel resistance. This is often the recoil of the cord retracting.
  4. Slowly release the tension by letting the cord retract on its own back to its starting position.
  5. Repeat this pulling and releasing process several times, ensuring the cord retracts smoothly each time.
  6. Pay attention to the tension while pulling. The cord should give you a moderate resistance that feels consistent with other similar equipment you've used in the past.
  7. Observe any signs of fraying, weakness, or abnormal stretching in the cord during the tension testing process. If any issues are detected, it's best to replace the pull cord before using the equipment.
  8. After testing, engage the equipment and test its functionality to ensure everything is operating as intended.


Remember to always follow the manufacturer's instructions for your specific equipment, as some may have additional guidelines or recommendations for testing pull cord tension.


What is the role of the pull cord in the engine ignition process?

The pull cord, also known as a starter cord or recoil starter, is used to start small engines such as those found in lawn mowers, chainsaws, and generators. Its role in the engine ignition process is to initiate the firing of the engine by turning the crankshaft and generating the necessary momentum to ignite the fuel-air mixture.


When the pull cord is pulled forcefully, it rotates the engine's crankshaft, which compresses the fuel-air mixture in the combustion chamber. This compression increases the temperature and pressure of the mixture. As the cord is released, it rewinds, and the stored energy is transferred to turn the crankshaft rapidly. This rapid rotation creates a spark in the spark plug, which ignites the compressed fuel-air mixture, starting the engine.


The pull cord is typically connected to a starter mechanism that includes a pulley, a spring, and a recoil mechanism. When the cord is pulled, the spring is tensioned, and upon release, it rewinds the cord back onto the pulley, ready for the next pull.


Overall, the pull cord is vital to the engine ignition process as it provides the initial force needed to rotate the crankshaft, compress the fuel-air mixture, and initiate the combustion required for starting the engine.


How to buy the right replacement pull cord for a lawn mower?

To buy the right replacement pull cord for a lawn mower, follow these steps:

  1. Determine the specifications: Note down the specific make, model, and year of your lawn mower. Additionally, find out the engine size and type. This information will help you identify the exact replacement pull cord.
  2. Measure the cord length: Take the old pull cord off the mower and measure its length. Ensure the measurement is accurate as it will help you buy the correct size.
  3. Consider the cord material: Replacement pull cords are typically available in nylon or braided steel. Nylon cords are suitable for lighter-duty mowers, while braided steel cords are more durable and ideal for heavy-duty mowers.
  4. Examine the attachment mechanism: Observe how the pull cord is attached to the starter assembly. There are generally two types of attachment mechanisms - a knot or a plastic handle. Ensure that the replacement cord has the same attachment method as your old one.
  5. Find a reliable supplier: Visit a local lawn mower repair shop or home improvement store that specializes in outdoor power equipment. Bring the information you gathered about your lawn mower and the old pull cord to find the right replacement.
  6. Consult the store associate: Speak to someone knowledgeable about lawn mower parts at the store. Provide them with the make, model, and engine specifications of your lawn mower. They will guide you in selecting the appropriate replacement pull cord.
  7. Consider buying a universal pull cord: If you are unable to find an exact match for your lawn mower, consider purchasing a universal pull cord kit. These kits are designed to fit a wide range of models and come with multiple attachments, allowing you to adapt it to fit your mower.
  8. Purchase the replacement pull cord: Once you have identified the correct replacement, make the purchase. Check if the package includes any additional hardware, such as screws or washers, which may be needed during installation.
  9. Install the new pull cord: Follow the manufacturer's instructions for installation. If needed, consult online resources or guides for step-by-step instructions specific to your lawn mower make and model.


Remember, if you are uncomfortable or unsure about replacing the pull cord yourself, it is best to consult a professional or take your lawn mower to a repair shop for assistance.
