Have you ever been in the middle of mowing your lawn when the pull rope snaps? It can be a frustrating experience, but it’s one that can be easily fixed with a few simple tools. Removing the old pull rope is easy, but you need to take care when installing the new rope to avoid damaging the recoil spring. In this article, we’ll walk you step-by-step through the process of replacing a pull rope on a lawn mower.
This task is simple, but it does require some basic tools. You’ll need a Phillips head screwdriver, a flat head screwdriver, and a new pull rope. You can find these items at most hardware stores. Once you have your tools, you’re ready to get started. First, you need to remove the old pull rope. To do this, use the Phillips head screwdriver to remove the two screws that hold the recoil starter cover in place. Once the cover is removed, you’ll see the recoil spring. Be careful not to let the spring unwind, as this can damage it. Next, use the flat head screwdriver to pry the old pull rope out of the pulley. Once the old pull rope is removed, you can install the new one.
To install the new pull rope, first feed the rope through the pulley. Then, tie a knot in the end of the rope and pull it tight. Next, wrap the rope around the recoil spring, making sure to keep it taut. Once the rope is wrapped around the spring, use the flat head screwdriver to hook the rope onto the pulley. Finally, replace the recoil starter cover and tighten the screws. Your lawn mower is now ready to use.
Identifying the Model and Type of Pull Rope
Correctly identifying the model and type of pull rope for your lawn mower is crucial to ensure a successful replacement. Each lawn mower model requires a specific type of pull rope, and incorrect selection can lead to operational problems or even safety hazards.
To determine the correct pull rope, follow these steps:
- Locate the model number: This is typically found on a sticker or plate attached to the mower’s frame or engine. Write down this number for reference.
- Identify the engine type: Most lawn mowers use either a two-stroke or four-stroke engine. The engine type will be indicated on the engine housing. If unsure, consult your lawn mower’s user manual or ask for assistance at a local hardware store.
- Check the pull rope length and diameter: Measure the length of the existing pull rope (excluding the starter rope grip). Use a ruler or measuring tape to get an accurate measurement. Also, measure the diameter of the rope at its thickest point.
With the model number, engine type, and pull rope dimensions in hand, you can now purchase the correct replacement pull rope for your lawn mower.

Removing the Old Pull Rope
1. Locate the Pull Rope Handle
Locate the starter pull rope handle on the lawn mower. It’s typically a small, plastic or rubber handle attached to a cord.
2. Detach the Handle
Look for a release mechanism or button on the handle. Press or pull on it to detach the handle from the lawn mower’s engine compartment. This will release tension on the pull rope.
3. Trace the Pull Rope Path and Remove It
With the handle detached, gently pull on the pull rope to trace its path through the engine compartment. It may run through pulleys or guides. Follow the rope’s path and identify any points where it’s attached to the engine or frame.
Using a wrench or pliers, detach the pull rope from its mounting points. Note the orientation of the rope and how it’s wrapped around pulleys or guides. This will help you install the new pull rope correctly.
Once all the attachments are removed, carefully pull the old pull rope out of the lawn mower’s engine compartment. Take care not to damage any other parts or wires while removing the rope.
| Step | Action |
|---|---|
| 1 | Locate the starter pull rope handle. |
| 2 | Detach the handle by pressing or pulling on the release mechanism. |
| 3 | Trace the pull rope path, identify any mounting points, detach the rope, and pull it out of the engine compartment. |
Preparing the New Pull Rope
To prepare the new pull rope, you will need to cut it to the appropriate length. To do this, measure the length of the old rope from the starter pulley to the handle. Add a few inches to this measurement to allow for knots and slack. Cut the new rope to this length.
Next, you will need to thread the new rope through the starter pulley. To do this, locate the starter pulley on the engine. It is usually located on the side of the engine, near the top. There will be a small hole in the center of the pulley. Thread the new rope through this hole.
Once the rope is threaded through the pulley, you will need to tie a knot in the end of the rope. To do this, simply fold the end of the rope back on itself and tie a knot. Make sure the knot is tight and secure.
Finally, you will need to attach the other end of the rope to the handle. To do this, simply tie the end of the rope to the handle using a knot. Make sure the knot is tight and secure.
| Measurement | Description |
|---|---|
| Length of the rope | Measure from the starter pulley to the handle and add a few inches |
| Starter Pulley | Locate the starter pulley on the side of the engine |
| Knot | Tie a knot at the end of the rope |
| Handle Attachment | Tie the other end of the rope to the handle |
Attaching the New Pull Rope to the Handle
5. Run the pull rope through the housing:
| Step | Description |
|---|---|
| a. | Locate the hole in the pull starter housing where the pull rope exits. |
| b. | Thread the new pull rope through the hole and out the opposite side. |
| c. | Pull the rope through until it is about 12 inches longer than the housing. |
| d. | Make a small loop in the end of the rope. |
| e. | Pass the loop through the hole in the pull handle. |
| f. | Pull the rope tight to secure the loop in place. |
| g. | Tie a knot in the rope about 1 inch from the handle. |
| h. | Cut off any excess rope. |
Threading the Pull Rope through the Engine
This step will vary slightly depending on the make and model of your lawn mower. However, the general steps are as follows:
1. Locate the starter housing.
This is usually a round or oval-shaped housing located on the side of the engine. There will be a small hole in the side of the housing.
2. Remove the starter cover.
This is usually held in place by a few screws. Once the cover is removed, you will see the starter pulley.
3. Tie a knot in the end of the pull rope.
This will keep the rope from slipping through the hole.
4. Thread the pull rope through the hole in the starter housing.
Make sure that the knot is on the inside of the housing.
5. Wrap the pull rope around the starter pulley.
Make sure that the rope is wrapped in the same direction that the pulley rotates.
6. Pull the pull rope until it is taut.
This will engage the starter clutch. Continue pulling the rope until the engine starts.
Once the engine has started, you can release the pull rope. The starter clutch will disengage, and the rope will rewind into the starter housing.
Replacing the Pull Rope
Locate the recoil starter assembly on the side of the engine. Grip the starter handle and pull it gently until it stops. Locate the rewind spring inside the assembly and rotate it clockwise until the tension is released. Remove the old pull rope from the handle and discard it.
Take the new pull rope and insert one end into the hole on the starter handle. Pull the rope through the handle until about six inches remain. Tie a knot in the end of the rope and insert it into the hole on the starter pulley. Pull the rope tight and wind it onto the starter pulley by turning it counterclockwise.
Reinstall the recoil starter assembly on the engine. Pull the starter handle gently until it engages the starter gear. Release the handle and it should recoil back into place. Test the pull rope to make sure it is working properly.
Adjusting the Tension of the Pull Rope
If the pull rope is too loose, it will not engage the starter gear properly. If it is too tight, it will be difficult to pull and may damage the starter recoil spring.
To adjust the tension of the pull rope, locate the tension screw on the recoil starter assembly. Turn the screw clockwise to tighten the rope and counterclockwise to loosen it. Adjust the tension until the pull rope recoils smoothly and engages the starter gear properly.
Tips:
- Use a high-quality pull rope that is specifically designed for lawn mowers.
- Do not overtighten the tension screw, as this can damage the starter recoil spring.
- If you are unable to adjust the tension of the pull rope, consult a qualified mechanic.
