The Hidden Value in Your Old MTD Snowflite
Before dismissing an MTD Snowflite, it’s crucial to understand what makes them special. Unlike many contemporary machines made with thinner, recycled metals and plastic components, older Snowflites were constructed almost entirely from heavy-gauge steel. This robust construction means they can withstand harsh conditions and heavy use far better than their modern counterparts.
The simplicity of their design is another significant advantage. They lack complex electronics and proprietary parts, making them remarkably easy to diagnose and repair with standard tools. For those willing to perform some maintenance, these machines represent incredible value, often outperforming newer, more expensive models in sheer durability and longevity.
Why Older Is Often Better
The MTD Snowflite hails from an era when outdoor power equipment was built to last for decades, not just a few seasons. The engines, often robust Tecumseh models, are known for their torque and reliability when properly maintained. The all-metal construction extends to the auger housing, chute, and controls, which resist cracking and breaking in frigid temperatures.
This durability means that even a machine that has been neglected for years can often be brought back to life. The parts that typically fail—belts, friction discs, and carburetor components—are still widely available and inexpensive to replace. Investing a small amount of time and money can yield a snow blower that will reliably serve you for many more winters to come.
Identifying Your MTD Snowflite Model
Over the years, MTD produced numerous Snowflite models with varying engine sizes and clearing widths. Identifying your specific model is the first step in sourcing the correct parts and manuals for any repair or restoration project. The model and serial number are typically found on a decal located on the main housing of the snow blower, often near the engine or on the back panel.
These older models often featured Tecumseh engines, which were workhorses of their time. Knowing the engine’s horsepower (HP) and the machine’s clearing width (e.g., 5/22 for 5 HP, 22-inch width) can help narrow down your search for information and parts. Below is a table of common MTD Snowflite configurations to help you identify your machine.
| Common Model Configuration | Engine Size (Approx. HP) | Clearing Width (Inches) | Key Feature |
|---|---|---|---|
| 5/22 or 5/24 | 5 HP | 22″ or 24″ | Compact and common for residential use. |
| 8/26 | 8 HP | 26″ | A popular and powerful mid-size option. |
| 10/33 | 10 HP | 33″ | Heavy-duty model for large driveways and heavy snow. |
Common MTD Snowflite Problems and How to Fix Them
Even the most durable machines encounter problems. For the MTD Snowflite, most issues fall into a few predictable categories: the engine won’t start, the drive system fails to engage, or the auger isn’t throwing snow effectively. Fortunately, these problems are almost always solvable without the need for a professional mechanic.
Approaching these issues systematically will save you time and frustration. Start with the simplest potential causes before moving on to more complex repairs. Always ensure the spark plug wire is disconnected before performing any work on the engine or drive system to prevent accidental starts.
Engine Won’t Start: Beyond the Basics
An engine that refuses to start is the most frequent complaint. While old fuel is a common culprit, the issue often lies within the carburetor, which can become gummed up with varnish deposits after sitting for extended periods. The small passages inside the carburetor, particularly the main and idle jets, are easily clogged.
A thorough carburetor cleaning is often all that’s needed. This involves removing the carburetor, disassembling it, cleaning all jets and passages with carburetor cleaner and compressed air, and reassembling with new gaskets. Pay special attention to the tiny hole in the brass nut that holds the float bowl on, as this is a common point of blockage. If cleaning doesn’t solve the problem, a full carburetor rebuild kit or a complete replacement carburetor is an inexpensive and effective solution.
Drive System Nightmares: When It Won’t Move
If the engine runs but the snow blower won’t move forward or backward, the problem is almost certainly in the friction drive system. This simple system uses a rubber-edged friction wheel that presses against a spinning metal drive plate to transfer power to the wheels. Over time, the rubber on the friction wheel wears down, gets contaminated with oil, or hardens with age.
A worn friction wheel will slip against the drive plate, resulting in weak or no movement. The solution is to replace the friction wheel. This is a straightforward repair that involves tipping the snow blower forward onto its auger housing, removing the bottom cover plate, and unbolting the old friction wheel assembly. While you’re there, clean the metal drive plate with brake cleaner to remove any grease or oil that could cause the new wheel to slip.
Auger and Impeller Issues: The Heart of the Blower
When the engine is running and the drive works, but the machine isn’t throwing snow, the issue lies with the auger and impeller system. The most common cause is a broken shear pin. Shear pins are designed to break if the auger hits a hard object, protecting the more expensive gearbox from damage. Always replace them with the exact OEM-specified pins.
If the shear pins are intact but the auger still doesn’t turn, the problem could be a worn or broken auger belt. Inspect the belt for cracks, glazing, or excessive stretching and replace it if necessary. Proper belt tension is critical for effective power transfer to the augers.
The Ultimate MTD Snowflite Tune-Up Guide
Performing an annual tune-up is the best way to ensure your MTD Snowflite starts on the first pull and runs strong all winter. This preventative maintenance is simple and addresses the most common points of failure before they become major problems.
Set aside an afternoon before the first snowfall to go through this checklist. A well-maintained machine is a reliable machine, and these simple steps will pay dividends when the snow starts to pile up.
Fuel System and Carburetor Care
Start by draining any old fuel from the tank. Old gasoline can separate and absorb moisture, leading to starting issues and carburetor clogging. Refill with fresh, stabilized fuel.
If the engine has been running rough, it’s a good time to clean the carburetor. Even if it seems to be running well, adding a fuel system cleaner to the first tank of gas can help dissolve minor varnish deposits and keep the fuel system clean throughout the season.
Ignition System Check
A strong spark is essential for reliable starting. Disconnect the spark plug wire and remove the spark plug. Check for a fouled or worn electrode and clean or replace it as needed.
Use a feeler gauge to set the spark plug gap to the manufacturer’s specification, which can usually be found online. A new spark plug is an inexpensive part that can significantly improve starting performance and fuel efficiency.
Lubrication and Adjustments
Proper lubrication prevents parts from seizing and ensures smooth operation. Grease the auger shaft fittings and any other lubrication points indicated in your manual. A light spray of silicone on the inside of the chute and impeller housing can help prevent snow from sticking.
Check the tension of all belts and the engagement of the friction drive wheel. Adjust cables as needed to ensure the auger and drive controls engage and disengage properly. Also, check the tire pressure to ensure proper traction.
Restoring vs. Replacing: When to Keep Your Snowflite
Faced with a non-running machine, many owners wonder if it’s worth fixing or if they should just buy a new one. In most cases, the cost of repairing an MTD Snowflite is a fraction of the price of a new, comparable two-stage snow blower. Given their superior build quality, a repaired vintage machine can often be a better long-term investment.
Consider the cost of parts for the most common repairs: a carburetor kit might cost very little, and a new friction wheel is also quite affordable. With a total investment often under a hundred dollars, you can have a machine that is more durable than many new models. However, if you decide that a repair isn’t for you, there are many avenues for offloading your old equipment. Learning where can I sell my snowblower can help you recoup some costs to put toward a new machine.
Ultimately, the decision to restore or replace comes down to your willingness to perform some basic mechanical work. For those who are, the MTD Snowflite offers an opportunity to own a truly heavy-duty piece of equipment without the heavy-duty price tag.
