6 best snow blower parts to get you through winter

The first heavy, wet snow of the season always seems to arrive overnight, turning simple morning chores into a significant challenge. Nothing stops a small farm in its tracks faster than a foot of snow blocking the path to the barn or the chicken coop. A reliable snow blower isn’t a luxury; it’s a critical tool for keeping your operation running when winter hits hard.

Why a Pre-Winter Parts Check is Essential

On a farm, preparedness isn’t just a good idea—it’s a core principle of self-reliance. Waiting for the first blizzard to discover your snow blower’s belt is cracked or the spark plug is fouled is a recipe for a frustrating, and potentially dangerous, morning. A simple parts check in the fall, when the weather is still mild, can mean the difference between a quick 30-minute clearing and a full day of shoveling just to reach your animals.

Think of it like checking your fences before letting livestock into a new pasture. You’re looking for the weak points before they become a problem. For a snow blower, the most common failure points are wear-and-tear items: belts that stretch and fray, scraper bars that wear thin, and shear pins designed to break. Identifying and replacing these parts before they fail is the key to a stress-free winter.

This proactive approach saves more than just time. A well-maintained machine runs more efficiently, using less fuel and putting less strain on the engine and transmission. It also protects the machine itself. A worn scraper bar, for instance, can lead to expensive damage to the auger housing, turning a simple $30 replacement into a much costlier repair.

Know Your Model Number Before You Buy Parts

Before you order a single part, the most important piece of information you need is your snow blower’s model and serial number. This is the golden ticket to getting parts that fit and function correctly. You can usually find it on a sticker or metal plate on the main housing of the machine, often near the wheels or on the back panel.

Take a picture of this sticker with your phone and save it. When you’re searching for parts online or at a local dealer, having the exact model number eliminates all guesswork. It ensures the belt you buy is the right length and width, the scraper bar has the correct bolt pattern, and the skid shoes are the proper size. Using the wrong part can lead to poor performance at best, and serious damage to your machine at worst.

Don’t fall into the trap of buying a part that "looks about right." A V-belt that’s even a half-inch too long will slip under load, failing to transfer power to the augers. A scraper bar with the wrong bolt spacing is useless. Taking two minutes to find your model number will save you hours of frustration and the cost of return shipping.

Arnold Universal Shear Pins for Quick Fixes

Shear pins are your snow blower’s first line of defense. These small pins are designed to snap and break if the auger hits something solid, like a frozen newspaper, a chunk of ice, or a misplaced rock. This sacrificial break protects the far more expensive gearbox from catastrophic damage. You should always have extras on hand.

The Arnold Universal Shear Pins are a smart addition to any repair kit because they cover a wide range of models from manufacturers like MTD, Cub Cadet, and Troy-Bilt. They come in various common sizes, ensuring you have a high chance of having the right one when you need it most. While OEM (Original Equipment Manufacturer) pins are always the best for a perfect fit, having a universal kit in your workshop means you’re never completely stuck.

If you have multiple machines or simply value the security of having a versatile backup, this kit is for you. It’s an inexpensive insurance policy against a mid-storm breakdown. For the farmer who wants to be prepared for anything without stocking dozens of model-specific parts, the Arnold kit is the practical choice.

MTD Genuine Parts V-Belts for Peak Power

The belts on your snow blower are like the transmission of your truck; they transfer power from the engine to the parts that do the work—the augers and the drive wheels. Over time, these rubber belts stretch, crack, and wear down, causing them to slip. A slipping belt means your machine won’t throw snow as far or propel itself with the force it needs to get through heavy drifts.

This is one area where sticking with genuine OEM parts pays dividends. A belt from MTD Genuine Parts (which covers brands like Cub Cadet, Troy-Bilt, and Yard Machines) is engineered specifically for your machine’s pulleys and tensioners. It’s made from a compound designed to stay flexible in freezing temperatures and to grip without slipping under the heavy load of wet snow.

If you depend on your machine to clear long driveways or paths to outbuildings, don’t compromise on the belt. A cheaper, generic belt might save you a few dollars upfront, but it’s likely to stretch or fail sooner, leaving you stranded mid-job. For peak performance and the reliability you need to keep your farm accessible, an OEM belt is the only way to go.

Champion RJ19LM Spark Plug for Easy Starts

There’s nothing more demoralizing than pulling the starter cord on a freezing morning only to be met with a sputtering engine that refuses to turn over. More often than not, the culprit is a weak or fouled spark plug. A spark plug is a simple, inexpensive part, but it’s absolutely critical for reliable ignition, especially in the cold, damp conditions of winter.

The Champion RJ19LM is a workhorse spark plug found in countless small engines, including many snow blowers. It’s known for its reliability and consistent spark, which is exactly what you need for a quick, easy start. Replacing your spark plug annually is one of the cheapest and most effective pieces of preventative maintenance you can perform. It ensures a strong spark to ignite the fuel mixture efficiently on the first or second pull.

This isn’t a fancy or high-tech part, and it doesn’t need to be. It’s a proven, dependable component that does its job without fuss. If you’ve ever battled with a hard-starting engine, or if it’s been more than a season since you last changed your plug, installing a new Champion RJ19LM is the smartest five-dollar investment you’ll make all winter.

OEM Toro Scraper Bar to Protect Pavement

The scraper bar is the long, flat piece of metal or hard plastic bolted to the bottom of the auger housing. Its job is to scrape the last layer of snow off the ground, ensuring a clean pass. More importantly, it maintains a critical gap between the fast-spinning augers and the hard pavement of your driveway or walkway.

As you use your snow blower, this bar wears down. A worn-out scraper bar not only leaves a layer of snow behind but also allows the auger housing—and potentially the augers themselves—to drag on the ground. This can damage both your machine and your concrete or asphalt surfaces. For this part, an OEM Toro Scraper Bar (or the equivalent for your brand) is non-negotiable.

Aftermarket or "universal" scraper bars rarely have the correct bolt hole pattern or the precise curvature to match the housing. An ill-fitting bar will leave streaks of snow and wear unevenly, defeating its purpose. If you want to get a clean finish and protect your property and your machine, buy the bar made specifically for your model. It’s a perfect-fit solution that ensures your snow blower works exactly as it was designed to.

Ariens Reversible Skid Shoes for Longevity

Skid shoes are the adjustable metal or composite plates on either side of the auger housing. They are the parts that actually slide along the ground, and their purpose is to set the height of the scraper bar. On a gravel driveway, you’ll set them lower to lift the scraper bar up, preventing it from scooping up rocks. On a smooth paved surface, you’ll set them higher for the closest possible clearing.

Because they are in constant contact with the ground, skid shoes are wear items that need regular replacement. This is where Ariens Reversible Skid Shoes show their clever design. They are designed symmetrically, so when one side wears down after a season or two of use, you don’t have to buy a new pair. You simply unbolt them, flip them over, and you have a brand-new surface to work with.

This simple feature effectively doubles the life of the part, saving you money and a trip to the parts store. It’s a practical, frugal solution that aligns perfectly with the mindset of a small farmer. If your machine is compatible and you’re looking for the best long-term value, reversible skid shoes are the obvious choice.

STA-BIL Fuel Stabilizer Prevents Clogging

The biggest enemy of a small engine that sits for any length of time is modern gasoline. The ethanol in today’s fuel attracts moisture and can form gummy deposits that clog the tiny passages in a carburetor. For a snow blower that sits idle from spring through fall, this is the most common cause of a no-start condition.

STA-BIL Fuel Stabilizer is essential preventative medicine for your fuel system. It’s not a repair part, but it prevents the need for one. Adding the correct amount to your gas can every time you fill it up keeps the fuel fresh for up to 24 months. It prevents the formation of gum and varnish, ensuring that when you need your snow blower, the fuel system is clean and ready to go.

Using a fuel stabilizer is far easier and cheaper than rebuilding a carburetor in the middle of winter. It’s a simple habit that pays for itself many times over in reliability and peace of mind. If you want your engine to start easily and run smoothly all winter, consider STA-BIL a required part of your maintenance routine.

Assembling Your Own Snow Blower Repair Kit

The best time to find a part is before you need it. Scrambling to find a shear pin or a belt with a foot of snow on the ground is a situation best avoided. A smarter approach is to assemble a small, dedicated repair kit with the most common failure items for your specific machine.

Store these parts in a clearly labeled box or bin on a shelf in your workshop. When a breakdown happens, you won’t have to search for a model number or drive to a store that may or may not be open. You can simply grab your kit, make the repair, and get back to work.

A basic but effective kit should include:

• Shear Pins: At least 4-6 extra pins and the corresponding cotter pins or nuts.
• Belts: A full set of replacement V-belts (one for the auger, one for the drive).
• Spark Plug: One or two new, gapped spark plugs.
• Fuel Stabilizer: A bottle of STA-BIL to treat your fuel.
• Starter Rope: A replacement pull-cord, just in case.
• Key: An extra ignition key, because they always go missing at the worst time.

Stay Ahead of the Storm with Maintenance

On a farm, reliable equipment is fundamental to success. A snow blower is no different from a tractor or a chainsaw; it requires a little attention before you put it to work to ensure it performs when you need it most. The small investment in a few key parts and an hour of your time in the fall is what separates a smooth winter from a stressful one.

By checking your belts, replacing your spark plug, and stocking a few critical spares, you are taking control of the situation. You’re no longer at the mercy of a sudden breakdown or a closed parts store. This proactive mindset is the essence of farming—anticipating needs, preparing for challenges, and ensuring you have the tools to keep moving forward, no matter what the weather brings.

Don’t wait for the first snowflake to think about your equipment. A well-stocked repair kit and a pre-season check-up will give you the confidence to face any storm. When the snow flies, you’ll be clearing your path while others are just discovering their problems.
