Is your MTD snowblower refusing to roar to life, leaving you stranded with a frozen driveway? The culprit might be a worn-out or broken pull cord, a common issue that can halt your winter preparedness in its tracks. Don't let a faulty cord dictate your snow-clearing capabilities; this guide will empower you to tackle this essential maintenance task with confidence.
Understanding how to replace your MTD snowblower's pull cord is not just about getting your machine running again; it's about extending its lifespan, ensuring reliability when you need it most, and saving yourself the cost of professional repair. This article will walk you through each step of the process, from identifying the problem to successfully installing a new cord, equipping you with the knowledge to conquer winter's chill.
Diagnosing the Pull Cord Problem
The first step in any repair is accurate diagnosis. A broken pull cord typically manifests in a few distinct ways. You might pull the cord and feel no resistance whatsoever, indicating it has snapped internally or detached from the recoil mechanism. Alternatively, the cord might feel loose and sloppy, not engaging the engine's starter mechanism properly, leading to a weak or non-existent spark. Sometimes, the cord might retract poorly or not at all, suggesting issues with the recoil spring or housing.
Carefully examine the cord itself for any visible signs of wear and tear. Look for fraying, nicks, or sections where the outer sheath appears damaged. If the cord feels brittle or stiff, it's likely nearing the end of its service life. Pay attention to how the cord behaves when you attempt to start the snowblower. Does it pull smoothly? Does it snap back with adequate force? Any deviation from a smooth, consistent action is a red flag.
Don't overlook the starter housing and recoil assembly. Sometimes, the issue isn't solely the cord but a problem with the mechanism it engages with. Check for cracks in the plastic housing, loose screws, or any debris that might be impeding the cord's movement. A thorough inspection will help you confirm that the pull cord is indeed the primary issue and not a symptom of a larger problem.
Gathering Your Tools and Materials
Before you begin the replacement process, ensure you have all the necessary tools and materials readily available. This will prevent frustrating interruptions and ensure a smooth workflow. You'll typically need a socket set or wrenches to remove the starter housing, a screwdriver set for any smaller screws, and possibly a pair of pliers for gripping and manipulating the cord. A utility knife or sharp scissors will be useful for trimming the new cord to the correct length.
The most crucial material is, of course, the replacement pull cord. It's essential to purchase a cord specifically designed for MTD snowblowers or a universal recoil starter rope that matches the diameter and material specifications of your original cord. Using an incorrect cord can lead to premature wear, poor performance, or even damage to the starter mechanism. Measure the length of your old cord before purchasing, or consult your snowblower's owner's manual for the recommended length and diameter.
Additionally, consider having a small container for organizing screws and small parts, a clean rag for wiping down components, and perhaps some light lubricant if any parts seem stiff. Having a well-lit workspace, such as a garage or shed, will also make the job significantly easier and safer.
Removing the Old Pull Cord Assembly
The first physical step is to access the pull cord assembly, which is usually housed within a plastic starter cover on top of the engine. Locate the screws or bolts securing this cover. These are typically accessible from the exterior of the cover. Carefully remove these fasteners using the appropriate socket or screwdriver. Keep these screws in a safe place, perhaps in a small container, so they don't get lost.
Once the screws are removed, gently lift the starter cover away from the engine. You may need to wiggle it slightly to dislodge it from any clips or seals. Inside, you'll see the recoil starter mechanism. The pull cord will be wound around a spool, with one end emerging from a hole in the housing and the other end attached to the engine's crankshaft. Carefully observe how the cord is routed and attached before proceeding.
With the cover removed, you can now focus on detaching the old cord. If the cord is broken, you might need to pull out the remaining pieces from the housing. If it's intact but you're replacing it preventatively, you'll need to unwind it from the spool. Often, there's a knot or a specific attachment point on the spool where the cord is secured. Carefully untie or detach the old cord from the spool and the engine crankshaft.
Installing the New Pull Cord
Begin by threading the new pull cord through the hole in the starter housing. Ensure you have enough slack to work with. Next, you'll need to attach the new cord to the recoil spool. This is often done by tying a secure knot, such as a figure-eight knot or a double overhand knot, at the end of the cord that will be inside the housing. Make sure this knot is robust and won't slip.
Now, carefully wind the new cord around the spool. As you wind, you'll need to create tension in the recoil spring. This is typically achieved by rotating the spool in the direction that tightens the spring. You'll feel resistance as you do this. Wind the cord evenly, ensuring it lies flat and doesn't overlap excessively. Leave enough cord extending from the housing to reach the handle.
Once the spool is wound and the spring is tensioned, attach the other end of the pull cord to the starter handle. This usually involves threading the cord through the handle and securing it with a knot or a specialized clip, depending on the design of your MTD snowblower. Ensure the knot is tight and the cord is securely fastened to the handle.
Reassembly and Testing
With the new pull cord installed and the starter handle secured, it's time to reassemble the starter housing. Carefully align the housing with the engine, ensuring any seals or gaskets are properly seated. Reinsert the screws or bolts that you removed earlier and tighten them securely, but avoid overtightening, which could strip the threads or crack the plastic.
Once the housing is reassembled, it's crucial to test the new pull cord. Gently pull the cord a few times to ensure it retracts smoothly and with proper tension. Check that the handle feels secure and doesn't wobble. If the cord feels stiff or doesn't retract fully, you may need to slightly adjust the winding of the cord on the spool or check for any obstructions.
Finally, attempt to start your MTD snowblower. The pull cord should now engage the engine's starter mechanism effectively, allowing you to get your machine running. Listen for any unusual noises and observe the engine's starting behavior. A successful start with a smooth pull indicates a job well done.

Frequently Asked Questions
How often should I replace the pull cord on my MTD snowblower?
There's no set schedule, but it's wise to inspect the pull cord annually before the snow season begins. If you notice fraying, stiffness, or a loss of retraction power, it's time for a replacement, even if it hasn't broken yet. Proactive replacement can prevent being stranded during a snowstorm.
Can I use any generic rope as a replacement pull cord?
It's strongly recommended to use a pull cord specifically designed for recoil starters or a high-quality universal starter rope. Generic ropes may not have the necessary tensile strength, abrasion resistance, or proper diameter, which can lead to premature failure, damage to the starter mechanism, or a less effective start.
What if the recoil spring is broken or weak?
If you discover that the recoil spring is damaged or has lost its tension, you'll need to replace the entire recoil assembly, not just the cord. This is a more involved repair, but the process is similar in that you'll still need to remove the starter housing. Consult your MTD snowblower's manual for specific instructions on replacing the recoil assembly.
My new cord feels too long or too short. What should I do?
If the cord feels too long, it might not retract fully or could snag. If it's too short, you might not be able to get a full pull to start the engine. You can trim the cord to the correct length after it's installed and you've tested the retraction. Ensure you leave enough length for a comfortable grip on the handle and a secure knot. If it's significantly too short, you may have the wrong cord or it wasn't wound correctly.
Do I need to disconnect the spark plug before working on the pull cord?
Yes, absolutely. For safety reasons, it is always recommended to disconnect the spark plug wire before performing any maintenance or repair on your snowblower's engine, including replacing the pull cord. This prevents accidental engine starts while you are working on the machine.
