Is your MTD snowblower struggling to engage its auger, leaving you stranded in the snow? A worn or broken auger cable is a common culprit, hindering the very function that makes your machine indispensable during winter storms. Don't let a faulty cable sideline your snow-clearing efforts; understanding how to replace it is a valuable skill for any MTD snowblower owner.
This guide will walk you through the entire process of replacing the auger cable on your MTD snowblower, from identifying the problem to successfully installing a new cable. We'll cover the necessary tools, safety precautions, step-by-step instructions, and troubleshooting tips, empowering you to tackle this repair with confidence and ensure your snowblower is ready for the next snowfall.
Understanding the Auger Cable and Its Function
The auger cable is a critical component in your MTD snowblower's operation, acting as the direct link between the control lever on your handle and the auger engagement mechanism. When you pull the auger lever, this cable transmits that force, engaging the drive system that spins the auger, which in turn collects and throws snow. It's essentially the "on" switch for your snow-clearing apparatus.
Over time, the constant tension, exposure to the elements, and the mechanical stress of repeated engagement can lead to wear and tear on the auger cable. This wear can manifest as fraying, stretching, or even complete breakage. A stretched cable might result in a sluggish or incomplete engagement of the auger, while a broken cable means the auger simply won't spin at all, rendering your snowblower ineffective.
Recognizing the signs of a failing auger cable is the first step to a timely repair. If your auger engages inconsistently, requires excessive force on the lever, or doesn't engage at all, it's highly probable that the auger cable is the issue. Regular inspection of the cable for visible damage can also help prevent unexpected failures during a snow event.
Gathering Your Tools and Safety Precautions
Before you begin the replacement process, it's essential to gather all the necessary tools and prioritize safety. You'll typically need a socket set or wrenches (common sizes include 10mm, 13mm, and 1/2 inch), a Phillips head screwdriver, a flathead screwdriver, pliers, a wire brush for cleaning, and potentially a torque wrench if your manual specifies torque settings for reassembly. A can of penetrating oil can be helpful for loosening stubborn bolts.
Safety is paramount when working on any machinery, especially a snowblower. Always ensure the snowblower is completely turned off, the spark plug wire is disconnected to prevent accidental starting, and the machine is on a stable, level surface. Wear sturdy work gloves to protect your hands from sharp edges and grease, and safety glasses to shield your eyes from debris. If you're working in a confined space, ensure adequate ventilation.
Having a clean workspace will make the job much smoother. Lay out your tools and the new auger cable within easy reach. It's also a good idea to have a container or magnetic tray to keep track of the bolts and nuts you remove, preventing them from getting lost in the snow or on the garage floor.
Step-by-Step Guide to Replacing the Auger Cable
Begin by locating the auger cable's attachment points. One end will be connected to the auger engagement lever on the handle assembly, and the other will be connected to the auger drive mechanism, often near the gearbox or belt tensioner. You may need to remove a protective cover or shroud to access these points.
Carefully disconnect the old cable. At the handle, there's usually a retaining clip or a bolt holding the cable end in place. At the auger mechanism, the cable might be secured by a spring clip, a bolt, or a bracket. Take note of how the cable is routed and secured, as you'll need to replicate this with the new cable. It's often helpful to take pictures as you disassemble.
Once the old cable is removed, route the new cable along the same path. Ensure it's not kinked or rubbing against any moving parts. Connect the new cable to the auger mechanism first, then to the engagement lever on the handle. Adjust the cable tension as needed; there's typically a turnbuckle or adjustment nut that allows you to fine-tune the engagement. The goal is for the auger to engage fully when the lever is pulled and disengage completely when released.
Troubleshooting Common Issues and Adjustments
After installing the new cable, test the auger engagement. If it still doesn't engage properly, the issue might be with the cable tension. Revisit the adjustment mechanism and tighten the cable slightly. Conversely, if the auger engages too aggressively or doesn't disengage fully, you may need to loosen the cable tension. The lever should feel firm but not overly stiff when pulled, and the auger should spin freely when disengaged.
Another common problem is a misrouted cable. Double-check that the cable is following the original path and isn't catching on anything. A cable that's rubbing against the frame or other components can cause premature wear and affect its smooth operation. Ensure all clips and brackets are securely fastened to keep the cable in its intended position.
If you've adjusted the tension and checked the routing, and the auger still isn't engaging correctly, the problem might lie deeper within the drive system. This could involve issues with the drive belt, pulleys, or the gearbox itself. In such cases, it might be beneficial to consult your MTD snowblower's service manual or seek professional assistance.
Preventative Maintenance and Extending Cable Life
To ensure your newly replaced auger cable lasts as long as possible, regular preventative maintenance is key. After each use, clear any snow and ice buildup from the auger housing and the cable itself. A quick wipe-down with a dry cloth can remove moisture that could lead to corrosion.
Periodically inspect the auger cable for any signs of fraying, stretching, or damage. Pay close attention to the areas where the cable connects to the lever and the drive mechanism, as these are common points of stress. Lubricating the cable's connection points and any moving parts it interacts with can also help reduce friction and wear.
Consider storing your snowblower in a dry, sheltered location when not in use. Exposure to the elements, especially moisture and extreme temperatures, can accelerate the degradation of the cable and other components. By taking these simple steps, you can significantly extend the lifespan of your auger cable and ensure your MTD snowblower remains in optimal working condition for years to come.

Frequently Asked Questions
How often should I inspect my MTD snowblower's auger cable?
It's recommended to inspect your auger cable at least once a year, typically before the start of the snow season. More frequent checks are advisable if you use your snowblower heavily or notice any signs of wear or inconsistent operation.
Can I use a generic auger cable if I can't find an exact MTD replacement?
While some generic cables might fit, it's always best to use a cable specifically designed for your MTD snowblower model. Using an incorrect cable can lead to improper fit, poor performance, and potential damage to other components. Check your owner's manual or contact MTD parts suppliers for the correct part number.
What are the signs that my auger cable needs replacement?
Common signs include the auger engaging slowly or inconsistently, requiring excessive force on the lever, or not engaging at all. Visible fraying, stretching, or a complete break in the cable are also clear indicators.
Is it difficult to adjust the auger cable tension?
Adjusting the auger cable tension is generally straightforward. Most MTD snowblowers have an adjustment nut or turnbuckle near one of the cable's attachment points. You'll typically turn this nut to either tighten or loosen the cable until the auger engages and disengages correctly.
What should I do if the new auger cable doesn't seem to fix the problem?
If replacing the cable doesn't resolve the issue, the problem might lie with other parts of the drive system, such as the drive belt, pulleys, or the gearbox. It's advisable to consult your snowblower's service manual for further troubleshooting or seek assistance from a qualified small engine mechanic.
