Ariens ST 2+2 Review: The Ultimate Guide to This Vintage Beast
In an era of disposable equipment, the Ariens ST 2+2 snow blower stands as a testament to American manufacturing. These vintage machines, often found in the back of a garage, represent a time when tools were built to last a lifetime. But can a decades-old snow blower truly compete with modern technology?
Many owners face the challenge of keeping these classics running, battling worn-out parts and the effects of modern fuel. The core problem isn’t the machine’s capability but the knowledge gap in maintaining this specific piece of history. This guide bridges that gap, offering expert solutions to keep your ST 2+2 performing like new.

Decoding the Ariens ST 2+2: A Vintage Powerhouse
The Ariens ST 2+2 is a compact, two-stage snow blower known for its incredible durability. The “2+2” in its name refers to its simple and effective transmission: two forward speeds and two reverse speeds. This provided operators with basic but essential control for tackling varying snow conditions.
Most of these models, like the common 932015, were equipped with a robust 5-horsepower Tecumseh engine. Unlike today’s machines with extensive plastic components, the ST 2+2 boasts an all-steel construction, from the auger housing to the handlebars. This is a primary reason so many are still in service decades later.
Identifying the exact age of your machine can be a crucial first step in finding the correct parts. If you’re unsure of its production year, you can learn how to determine what year your Ariens snowblower is to ensure you source the right components for any repairs.
The Hidden Threat: Why Your ST 2+2 Might Fail
Owning a vintage ST 2+2 comes with a unique set of challenges that can sideline it if ignored. The most significant issue is age-related wear on critical components. Rubber parts, like belts and the friction disc, degrade over time, leading to a loss of drive power or auger function.
Another major problem stems from modern gasoline. Today’s ethanol-blended fuels can wreak havoc on the original carburetors and fuel lines of these older Tecumseh engines. This often leads to frustrating starting issues, rough running, or the engine dying under load.
Finally, parts availability can seem daunting. While you can’t walk into a big-box store and find parts for an ST 2+2, they are surprisingly available if you know where to look. Neglecting these core areas is the fastest way to turn a reliable workhorse into a garage ornament.
Your Essential ST 2+2 Maintenance & Repair Blueprint
Bringing an Ariens ST 2+2 back to its former glory requires a systematic approach. By focusing on the three critical systems—engine, drivetrain, and auger—you can solve nearly any problem you encounter. This section provides actionable steps to diagnose and repair your machine.
Revitalizing the Tecumseh Engine
The heart of your ST 2+2 is its Tecumseh engine, and the key to its reliability is the fuel system. If your snow blower runs rough or stalls in heavy snow, the carburetor is the most likely culprit. A thorough cleaning is often all that’s needed to resolve fuel delivery problems.
Beyond the carburetor, ignition health is paramount. A fresh spark plug, correctly gapped, ensures a strong spark for reliable starting in cold weather. For detailed instructions, consulting a guide on the proper Ariens snow blower spark plug gap can make a significant difference in performance.
Regular oil changes are also non-negotiable for engine longevity. Using the correct viscosity oil for winter operation ensures proper lubrication and protects internal components from premature wear.
Mastering the Drivetrain: Belts and Friction Disc
Power from the engine is transferred to the wheels and auger via a system of belts and a rubber-edged friction disc. The friction disc is the most critical wear item in the drive system. As it wears down, you’ll notice the machine struggling to move, especially in reverse.
Inspecting the friction disc involves tipping the snow blower forward onto its housing and removing the bottom cover. A worn disc will be glazed, cracked, or worn down to the metal wheel. Replacement is straightforward and is the single most effective repair for restoring drive power.
Likewise, the drive and auger belts can stretch and crack with age. Worn belts will slip under load, resulting in weak propulsion or a slow-spinning auger. Always replace belts that show visible signs of damage or glazing to ensure efficient power transfer.
Solving Common Operational Failures
Even with a healthy engine and drivetrain, you may encounter specific operational issues. For instance, if the auger fails to engage, the cause is often a broken shear bolt. These small bolts are designed to break if the auger hits a hard object, protecting the much more expensive gearbox from damage.
Many of the operational issues you might face are not unique to this specific model. Common problems like a clogged chute or issues with the scraper bar adjustment are universal. Understanding these shared issues, like those found in guides for other Ariens snow blowers with problems, can provide valuable troubleshooting insights.
| Problem | Likely Cause | Solution |
|---|---|---|
| Engine starts, then dies under load | Clogged main jet in carburetor | Thoroughly clean the carburetor, paying close attention to all small orifices. |
| Snow blower won’t move forward or reverse | Worn or oil-contaminated friction disc | Replace the friction disc and ensure the drive plate is clean and free of oil. |
| Auger spins, but doesn’t throw snow | Broken shear bolts or a slipping auger belt | Inspect and replace shear bolts. Check auger belt tension and condition. |
| Machine pulls to one side | Improper tire pressure or a worn tire | Ensure both tires are inflated to the same PSI. Replace tires if wear is uneven. |
| Hard to start in cold weather | Old fuel, fouled spark plug, or stale gas | Use fresh, stabilized fuel. Replace and correctly gap the spark plug. |
Is the Ariens ST 2+2 a Smart Buy Today?
In a market saturated with complex machines, the Ariens ST 2+2’s simplicity is its greatest strength. Its heavy-gauge steel construction offers a level of durability that is simply unmatched by most modern residential snow blowers. This is a machine designed to be repaired, not replaced.
However, it lacks modern conveniences like power steering, heated handgrips, or a remote chute control. Its 20-inch clearing width is also smaller than many contemporary models. For those with small to medium-sized driveways who value reliability over features, the ST 2+2 remains an excellent choice.
The true value of the ST 2+2 lies in its longevity. The all-steel auger and gearcase are notoriously overbuilt, capable of lasting 50 years or more with basic maintenance. This is a level of engineering focused on sustainability that is rarely seen today.
Sourcing Parts and Support for a Classic
Keeping a vintage ST 2+2 running is easier than you might think. While you won’t find parts at a local hardware store, a wealth of resources exists online. Websites specializing in outdoor power equipment parts are excellent sources for new old stock (NOS) and quality aftermarket components.
Online forums and communities dedicated to snow blower repair are invaluable. These platforms connect you with experienced owners and technicians who have likely solved the exact problem you are facing. They are often the best place to find part numbers and diagrams.
Don’t overlook local small engine repair shops. Many seasoned mechanics have experience with these Tecumseh-powered machines and may have access to parts or be able to rebuild components like the carburetor.
Final Verdict: A Timeless Workhorse for the Savvy Owner
The Ariens ST 2+2 is more than just an old snow blower; it’s a piece of engineering history. It represents a commitment to quality and repairability that stands in stark contrast to the throwaway culture of modern consumer goods. For the owner willing to perform basic maintenance, it offers unparalleled reliability.
Before purchasing or restoring one, conduct a thorough inspection. Check the auger gearbox for leaks, examine the inside of the fuel tank for rust, and look for excessive wear on the auger paddles. A solid foundation is key to a successful project.
Ultimately, choosing to maintain an Ariens ST 2+2 is a rewarding experience. It’s an investment in a durable tool that, with a little care, will continue to fight winter storms for many years to come, long after newer, more complex machines have been discarded.
