Tools and Materials Needed
- Replacement pull cord (make sure it’s the correct size for your mower)
- Screwdrivers (Phillips and flathead)
- Pliers
- Scissors or a knife
- Socket wrench set
- Safety gloves
- Lighter or matches (for sealing the cord ends)
Step-by-Step Guide
- Safety First:
- Disconnect the spark plug wire to prevent accidental starts.
- Wear safety gloves to protect your hands from sharp edges.
- Remove the Starter Assembly:
- Locate the starter assembly, usually on top of the mower.
- Use a screwdriver or socket wrench to remove the screws or bolts holding the starter assembly in place.
- Carefully lift the starter assembly off the mower.
- Access the Pulley:
- Turn the starter assembly over to expose the underside where the pulley and cord are located.
- Remove any cover or retaining screws to access the pulley.
- Remove the Old Cord:
- If the old cord is still attached, use pliers to remove the knot from the pulley.
- Carefully unwind the old cord from the pulley and pull it out through the starter handle.
- Prepare the New Cord:
- Cut the new cord to the appropriate length (refer to your mower’s manual for the correct length).
- Use a lighter or matches to melt the ends of the cord slightly to prevent fraying.
- Install the New Cord:
- Thread one end of the new cord through the hole in the pulley.
- Tie a secure knot at the end of the cord to prevent it from slipping through the pulley.
- Wind the cord around the pulley in the direction specified by your mower’s manual (usually indicated by an arrow on the pulley).
- Reattach the Starter Handle:
- Thread the other end of the new cord through the starter handle.
- Tie a secure knot to keep the handle attached to the cord.
- Tension the Recoil Spring:
- Hold the pulley and gently allow it to rewind the new cord onto the pulley. Be careful not to let the cord retract too quickly, which could cause the spring to lose tension.
- Ensure the cord retracts smoothly and the handle sits snugly against the starter assembly.
- Reinstall the Starter Assembly:
- Place the starter assembly back onto the mower.
- Secure it with the screws or bolts you removed earlier, using a screwdriver or socket wrench.
- Reconnect the Spark Plug:
- Reattach the spark plug wire to the spark plug.
- Test the New Cord:
- Pull the starter handle a few times to ensure the new cord operates smoothly and the engine engages properly.
Tips for replacing lawn mower cord
Replacing the cable on a lawn mower, whether it’s the drive cable, throttle cable, or brake cable, can restore the functionality of your mower. Here are some tips and a step-by-step guide to help you with the replacement process:
General Tips
- Refer to the Manual: Always check your lawn mower’s manual for specific instructions related to your model. This will provide details on the type of cable needed and any special instructions.
- Use Proper Tools: Ensure you have the necessary tools, such as screwdrivers, pliers, a socket wrench set, and any specific tools recommended in your mower’s manual.
- Safety First: Disconnect the spark plug to prevent accidental starts. Wear safety gloves to protect your hands.
- Take Pictures: Before removing the old cable, take pictures of how it is routed and connected. This will help you install the new cable correctly.
- Buy the Correct Cable: Ensure the replacement cable is the correct length and type for your specific mower model.
Step-by-Step Guide
1. Identify the Cable to be Replaced
- Determine whether you need to replace the drive cable, throttle cable, or brake cable.
- Locate both ends of the cable to see where it connects to the control lever and the mower mechanism.
2. Prepare the Mower
- Disconnect the spark plug wire to prevent accidental starts.
- Tilt the mower onto its side, ensuring the air filter and carburetor are facing up to prevent fuel or oil leakage.
3. Remove the Old Cable
- For Throttle or Drive Cable:
- Loosen and remove any screws or bolts securing the cable to the handle.
- Detach the cable from the control lever on the handle.
- Trace the cable down to the engine or transmission and disconnect it from the linkage or attachment point.
- For Brake Cable:
- Release any tension on the brake cable by pulling back on the brake lever.
- Remove any retaining clips or fasteners holding the cable in place.
- Disconnect the cable from the brake mechanism near the engine.
4. Install the New Cable
- For Throttle or Drive Cable:
- Attach one end of the new cable to the control lever on the handle, ensuring it is securely connected.
- Route the cable along the same path as the old cable, securing it with any clips or guides.
- Connect the other end of the cable to the engine linkage or transmission, ensuring it operates smoothly.
- For Brake Cable:
- Attach one end of the new cable to the brake lever on the handle.
- Route the cable down to the brake mechanism, securing it with any clips or guides.
- Connect the other end of the cable to the brake mechanism and ensure it is properly tensioned.
5. Adjust the Cable Tension
- For throttle and drive cables, adjust the tension according to the manufacturer’s instructions. This usually involves using an adjustment screw or nut to ensure the cable operates smoothly without being too tight or too loose.
- For brake cables, ensure the brake lever engages and disengages the brake properly. Adjust the tension if necessary to achieve the correct operation.
6. Test the Mower
- Reconnect the spark plug wire.
- Start the mower and test the new cable to ensure it operates correctly.
- For throttle cables, check that the engine speed changes appropriately.
- For drive cables, ensure the self-propelled function engages smoothly.
- For brake cables, ensure the brake engages and disengages properly.
Additional Tips
- Lubricate Moving Parts: Before installing the new cable, consider lubricating any moving parts it connects to. This can help ensure smooth operation and extend the life of the cable.
- Regular Maintenance: Periodically check the cables for wear and adjust the tension as needed. Regular maintenance can prevent future issues and prolong the life of your mower.
- Proper Storage: Store your mower in a dry, sheltered place to prevent rust and deterioration of cables and other components.
By following these steps and tips, you can effectively replace the cable on your lawn mower, ensuring it continues to operate efficiently and safely.
