What to know about replacement parts for your snow blower

Winter storms can transform your yard into a snowy wonderland, but they also bring the dreaded task of clearing driveways and walkways. That’s where a snowblower comes to the rescue! Whether you’re new to owning one or looking to get the most out of your machine, understanding its parts is a great place to start. Knowing how each part works helps you maintain your snowblower and troubleshoot when parts break down. 

We’ll dive into the key parts of a snowblower, how they function, and tips for keeping them in good shape. Let’s get started!

The main parts of a snowblower and their functions

A snowblower may seem like a complex machine, but it’s really just a combination of mechanical parts working together to move snow efficiently. Here’s a breakdown of its most important parts:

Auger

The auger is the spiral-shaped blade at the front of the snowblower. Its primary job is to scoop up snow and feed it into the machine for further processing.

• In a single-stage snowblower, the auger does all the work, from gathering snow to throwing it out through the chute.
• In a two-stage snowblower, the auger gathers snow while an impeller handles the snow-throwing.

Maintenance tip: Keep the auger blades free of ice buildup and inspect them for wear or damage after heavy use.

Impeller

Found in two-stage and three-stage snowblowers, the impeller is a fast-spinning fan-like part behind the auger. Its role is to propel the snow out of the chute with force, ensuring it’s thrown far from the machine. Without the impeller, snow might clog in the machine, reducing its effectiveness.

Maintenance tip: Clear any debris or compacted snow from the impeller regularly to prevent blockages.

Chute

The chute directs where the snow is thrown. It’s usually adjustable so you can control the angle and direction of the discharge.

Types of chutes:

• Manual chutes require you to adjust them by hand.
• Electric or joystick-operated chutes offer more convenience by allowing adjustments without stopping.

Maintenance tip: Lubricate the chute controls to keep them moving smoothly, especially in freezing temperatures.

Skid shoes

Skid shoes are small metal or plastic plates on the bottom of the snowblower that help maintain a consistent clearance between the auger housing and the ground. They prevent the auger from scraping the surface and protect your driveway or sidewalk. You can raise or lower skid shoes depending on the surface you’re clearing (e.g., gravel, pavement).

Maintenance tip: Inspect skid shoes frequently and replace them if they’re worn down to avoid damaging your snowblower or the surface below.

Scraper bar

The scraper bar is a durable strip located at the bottom of the auger housing. It helps remove packed snow and ice that the auger might not fully pick up. A worn scraper bar can lead to uneven snow removal and cause damage to the machine or your pavement.

Maintenance tip: Replace the scraper bar when it becomes too thin or uneven. This ensures a clean, efficient clearing job every time.

Other important parts to know

While the auger, impeller, chute, skid shoes, and scraper bar are the most important parts, there are several other parts that keep your snowblower running smoothly:

Drive system

The drive system controls the movement of your snowblower. It includes belts, pulleys, and gears that transfer power from the engine to the wheels or tracks.

Types of drive systems:

• Friction disc drive: Common in most snowblowers, this system uses a rubberized disc to transfer motion.
• Hydrostatic drive: Found in higher-end models, this system allows for more precise speed control.

Maintenance tip: Check drive belts regularly for signs of wear or cracks, and replace them as needed.

Shear pins

Shear pins are safety devices that connect the auger to the drive shaft. If the auger encounters a heavy obstacle (like a rock or chunk of ice), the pins break to protect the machine from serious damage. This prevents costly repairs to your snowblower’s engine or gearbox.

Maintenance tip: Keep spare shear pins on hand, especially during heavy snow seasons. Replacing them is usually a quick fix.

Tires or tracks

Tires or tracks provide the traction needed to maneuver your snowblower across different surfaces.

Tires vs. tracks:

• Tires work well on flat, even surfaces like driveways.
• Tracks are better for handling steep or uneven terrain, as they offer greater stability.

Maintenance tip: Ensure tires are properly inflated and inspect tracks for signs of wear to avoid slipping or reduced control.

Engine

The engine is the powerhouse of the snowblower, providing the energy needed to drive the auger, impeller, and wheels.

Types of engines:

• Gas-powered engines: Offer more power for tackling heavy snow but require regular maintenance.
• Electric motors: Quieter and easier to maintain but best suited for lighter snowfalls.

Maintenance tip: Follow the manufacturer’s recommendations for oil changes, spark plug replacements, and general tune-ups to keep the engine running smoothly.

Hand warmers and headlights

Some modern snowblowers come with built-in conveniences like heated handles and headlights. These features make snow removal more comfortable and safer, especially during early morning or late-night clearing.

Maintenance tip: Keep electrical connections clean and dry to ensure these features function properly when you need them.

Tips for maintaining your snowblower parts

Keeping your snowblower in good shape involves regular care and attention. Here are some tips to ensure your machine lasts for years:

1. Inspect all major parts before winter starts, looking for wear or damage that needs repair.
2. Remove snow, ice, and debris to prevent rust and keep moving parts functioning properly.
3. Keep your snowblower in a garage or shed to protect it from the elements when not in use.
4. Every snowblower is a little different, so refer to your manual for specific maintenance instructions and replacement part recommendations.
