This comprehensive guide will walk you through the process of replacing the pull cord on your MTD snowblower, empowering you to tackle this DIY repair with confidence.
Understanding how to perform this essential maintenance can save you time and money, ensuring your snowblower is ready to tackle any blizzard. We'll cover everything from identifying the problem to selecting the right parts and executing the replacement safely and effectively. By the end of this article, you'll have the knowledge and practical steps needed to get your MTD snowblower's pull cord back in working order, ready for the next snowfall.
Diagnosing the Pull Cord Problem
The first step in replacing your MTD snowblower's pull cord is to accurately diagnose the issue. A frayed, snapped, or excessively loose cord are all clear indicators that replacement is necessary. Sometimes, the cord might feel stiff or difficult to pull, which can also point to internal wear or damage within the recoil starter mechanism itself. Visually inspect the entire length of the cord, looking for any signs of fraying, cuts, or thinning.
Beyond the visible cord, pay attention to how the starter mechanism engages. If the cord pulls out smoothly but doesn't retract properly, or if it feels "mushy" without engaging the engine's flywheel, the problem might extend beyond just the rope itself. In some cases, the internal spring within the recoil assembly could be broken or uncoiled, preventing proper tension and retraction.
To confirm the cord is the primary issue, try to pull it firmly. If it snaps easily, feels like it's slipping internally, or doesn't provide any resistance, it's almost certainly time for a new one. If the cord seems intact but the engine still won't turn over when you pull it, you might be looking at a more complex issue within the recoil starter assembly or even the engine itself, though a bad pull cord is the most frequent offender.
Gathering Your Tools and Materials
Before you begin the replacement process, ensure you have all the necessary tools and materials readily available. This will streamline the repair and prevent frustrating interruptions. You'll typically need a socket set or wrenches to remove the starter housing, a screwdriver set for any smaller screws, and a pair of pliers for gripping and manipulating the cord. A utility knife or sharp scissors will be essential for cutting the new cord to the correct length.
The most crucial material is, of course, the replacement pull cord. It's vital to use a cord that is specifically designed for MTD snowblowers or a universal starter rope of the appropriate thickness and material. Look for a durable, braided nylon or polyester cord that can withstand the rigors of repeated pulling in cold weather. You'll also need to determine the correct length; it's generally better to have a little extra than not enough. Some MTD models might also require a specific type of knot or a small ferrule to secure the end of the cord.
Additionally, consider having some light lubricant on hand, such as WD-40 or a silicone spray, to lubricate the recoil mechanism after cleaning. A clean rag or shop towel will be useful for wiping away any dirt or debris. Having a small container or bag to keep track of removed screws and parts is also a good practice to avoid losing them.
Removing the Old Pull Cord
The first physical step is to access the recoil starter assembly. This usually involves removing the starter housing, which is the large plastic or metal cover on top of the engine where the pull cord emerges. Locate the bolts or screws securing the housing to the engine block. These are typically hex-head bolts, so use the appropriate socket or wrench to loosen and remove them. Keep these screws in a safe place, perhaps in a small magnetic tray, to prevent them from getting lost.
Once the housing is removed, you'll see the recoil starter mechanism. The old pull cord will likely be wound around a spool within this assembly. You'll need to carefully release the tension on the spring. Some recoil starters have a small hole on the side of the spool where you can insert a nail or screwdriver to hold the spring in place while you work. If your model doesn't have this, you'll need to be cautious as you unwind the cord to avoid releasing the spring's tension suddenly, which can cause it to snap back forcefully.
Gently pull the remaining cord out of the housing. You'll likely find the end of the cord is tied to a handle. Carefully untie or cut the knot holding the handle to the cord. Then, slowly feed the rest of the old cord out of the recoil mechanism. Observe how the cord is routed through the housing and around the spool; this will be helpful when installing the new cord.
Installing the New Pull Cord
With the old cord removed and the recoil mechanism exposed, it's time to install the new one. First, cut your new pull cord to the appropriate length. A good rule of thumb is to measure the old cord and add a few extra inches, or consult your MTD snowblower's owner's manual for the exact recommended length. Thread one end of the new cord through the designated hole in the recoil spool.
Next, you'll need to secure the end of the cord to the spool. This is often done by tying a sturdy knot, such as a figure-eight or a double overhand knot, to prevent it from pulling back through the spool. Some recoil assemblies might have a small hole or a specific attachment point for the cord. If your replacement cord came with a ferrule, you might use that to crimp onto the end of the cord for a more secure attachment.
Now, carefully wind the new cord onto the spool. As you wind, ensure the cord is laying flat and evenly. You'll need to create tension in the recoil spring as you wind. If you used a nail or screwdriver to hold the spring, remove it carefully as you begin to wind. Continue winding until the cord is mostly taken up, leaving just enough slack to attach the starter handle.
Reassembly and Testing
Before reattaching the starter housing, attach the starter handle to the free end of the new pull cord. Again, a secure knot is essential here. Ensure the knot is tight and won't slip. Once the handle is attached, carefully feed the cord through the opening in the starter housing.
Now, align the starter housing with the engine block and secure it with the bolts or screws you removed earlier. Tighten them firmly but avoid over-tightening, which could strip the threads. Once the housing is reattached, give the new pull cord a few gentle tugs to ensure it retracts smoothly and engages the engine. You should feel a distinct "catch" as the recoil mechanism engages.
Finally, it's time for the ultimate test. With the snowblower in a safe, open area, give the pull cord a firm, steady pull. If everything has been done correctly, the engine should turn over. If it doesn't start immediately, try a few more pulls. If it still struggles, double-check your work, ensuring the cord is properly seated and the spring has adequate tension. A successful start means your MTD snowblower is ready to tackle the snow once again.

Frequently Asked Questions
How do I know if I need to replace the pull cord or the entire recoil starter assembly?
If the cord itself is frayed, snapped, or feels excessively worn, replacing just the cord is usually sufficient. However, if the cord retracts poorly, feels loose even when new, or the engine doesn't engage when you pull, the internal spring or other components of the recoil starter assembly might be damaged and require replacement of the entire unit.
What type of cord should I use for my MTD snowblower?
You should use a durable, braided nylon or polyester starter rope. It's important to match the thickness of the new cord to the old one, or consult your MTD snowblower's manual for specifications. Using a cord that is too thin can lead to premature wear, while one that is too thick might not fit properly within the recoil mechanism.
How long should the replacement pull cord be?
The exact length can vary by MTD snowblower model. A good starting point is to measure the old cord and add a few extra inches. If you no longer have the old cord, consult your snowblower's owner's manual, as it often specifies the correct length. It's generally better to have a slightly longer cord than one that is too short.
Can I replace the pull cord without removing the entire starter housing?
In most cases, you will need to remove the starter housing to access the recoil starter mechanism and the spool where the cord is wound. Attempting to replace the cord without proper access can be difficult and may lead to damage to the recoil assembly or improper installation.
What if the new cord doesn't retract properly after installation?
If the new cord doesn't retract smoothly, it could indicate that the recoil spring is not properly tensioned, the cord is not routed correctly through the housing, or the cord is binding on an internal component. Double-check that the spring has been wound with sufficient tension and that the cord is not snagged anywhere. If the problem persists, the recoil starter assembly itself might be faulty.
