The sweet sound of a well-maintained lawnmower is music to any homeowner’s ears. But what happens when that familiar pull starts feeling sluggish, or worse, snaps altogether? A broken pull cord can quickly turn a simple chore into a frustrating ordeal. Thankfully, replacing a pull cord on an MTD lawnmower is a relatively straightforward task that most DIY enthusiasts can handle. In this article, we’ll walk you through the step-by-step process, from identifying the right cord to completing the replacement. We’ll also cover some helpful tips and tricks to ensure a smooth and successful repair.
The pull cord is a vital part of your lawnmower’s starting system. It’s attached to the recoil spring and when pulled, rotates the engine crankshaft, allowing the engine to start. A broken pull cord can be caused by wear and tear, a sudden tug, or even rodent damage. Replacing the cord is essential for your lawnmower to function properly.
Identifying Your MTD Lawn Mower Model
Before diving into the replacement process, it’s crucial to know the specific model of your MTD lawnmower. The pull cord configuration can vary slightly depending on the mower’s age and design. Here’s how to identify your model:
- Locate the Model Number: Check the mower’s side or underneath for a sticker or plate that displays the model number.
- Consult the MTD Website: Once you have the model number, visit the MTD website (https://www.mtdproducts.com/) and navigate to the “Support” or “Parts” section. This will allow you to find detailed diagrams and parts lists for your specific model.
Gather Your Tools and Parts
Now that you’ve identified your MTD lawnmower model, you can gather the necessary tools and parts for the repair:
Tools:
- Screwdriver: A standard Phillips head screwdriver is usually sufficient for most MTD lawnmowers.
- Pliers: To help with removing and installing the pull cord.
- Wrench: You may need a wrench to loosen any nuts or bolts securing the pull cord housing.
Parts:

Replacing the Pull Cord: Step-by-Step Guide
Step 1: Disengage the Spark Plug
- Safety First: Always disconnect the spark plug wire from the spark plug to prevent accidental starting during the repair process.
- Locate the Spark Plug: It’s usually located on the top or side of the engine, often beneath a removable cover.
Step 2: Remove the Pull Cord Housing
- Identify the Housing: The pull cord housing is a plastic or metal cover that encloses the pull cord mechanism.
- Locate the Fasteners: The housing is typically held in place by screws or nuts.
- Remove the Fasteners: Carefully remove the screws or nuts using your screwdriver or wrench.
- Remove the Housing: Once the fasteners are removed, gently lift the pull cord housing to reveal the inner workings.
Step 3: Disconnect the Old Pull Cord
- Locate the Attachment Point: The old pull cord is usually attached to the recoil spring assembly with a small metal hook or clip.
- Remove the Clip: Use pliers to carefully remove the clip or hook holding the pull cord in place.
Step 4: Install the New Pull Cord
- Attach the New Pull Cord: Feed the new pull cord through the housing and clip it to the recoil spring assembly using the hook or clip.
- Check for Tension: Ensure the new pull cord is properly attached and has adequate tension.
Step 5: Reassemble the Pull Cord Housing
- Secure the Housing: Carefully replace the pull cord housing and reattach the fasteners you removed earlier.
- Tighten the Fasteners: Make sure all fasteners are securely tightened.
Step 6: Reconnect the Spark Plug Wire

Troubleshooting and Tips
- Cord Length: If the new pull cord feels too short or too long, you may need to adjust the recoil spring assembly. Consult your lawnmower’s manual or the MTD website for specific instructions.
- Tightness: Ensure all screws and nuts are securely tightened to prevent the housing from coming loose during operation.
- Lubrication: If your pull cord is difficult to pull, you can try applying a small amount of light lubricant to the recoil spring assembly. However, avoid using heavy grease or oil, as this can attract dirt and debris.
