A two stage snow blower is a powerful machine that uses two separate parts to clear deep snow. It first pulls snow in with an auger, then throws it out through a high-speed impeller.
If you get a lot of snow where you live, you need the right tool for the job. A regular shovel won’t cut it for heavy drifts or long driveways. That’s where this type of machine comes in.
I’ve used many snow blowers over the years. The two stage model is my go-to for serious winter weather. It handles conditions that would stop a smaller blower in its tracks.
This guide will explain everything about these machines. We’ll look at how they work, when you need one, and how to pick the best model for your home.
What’s a Two Stage Snow Blower Really?
Let’s break down the name. “Two stage” means it has two steps to move snow. The first stage gathers it up. The second stage throws it far away.
Think of it like a factory line for snow. The auger acts as the collector at the front. It spins and cuts into the snow bank. Then it feeds the snow to the impeller in the second stage.
The impeller is a fast-spinning fan. It takes the snow from the auger and launches it out the chute. This dual-action system is what gives the machine its power. It can move a huge amount of snow quickly.
When you ask “what’s a two stage snow blower,” you’re asking about this process. It’s not just one tool doing the work. It’s two tools working together as a team.
This design makes it different from single stage models. Those only have one part doing both jobs. They work okay for light snow but struggle with anything heavy or deep.
Understanding what’s a two stage snow blower helps you see why it costs more. You’re getting two systems in one machine. That extra engineering means better performance when you really need it.
How a Two Stage Snow Blower Works
The process starts when you engage the auger. This is the big spiral metal piece at the front of the machine. It rotates and bites into the snowpack.
The auger’s job is to break up and collect the snow. It can handle ice chunks and packed snow that would jam other blowers. The metal construction is tough enough for rough conditions.
Once the auger gathers the snow, it moves it toward the center. There’s an opening that leads to the second stage. This is where the impeller sits waiting.
The impeller spins at very high speeds. Think of a fan on overdrive. It creates strong airflow that picks up the snow from the auger. Then it forces that snow up and out through the discharge chute.
You control where the snow goes by turning the chute. Most models have a crank or lever for this. Some fancy ones even have joystick controls for easy aiming.
The two stage system means snow gets moved in two distinct motions. First it’s gathered horizontally by the auger. Then it’s thrown vertically by the impeller. This combo clears paths fast.
According to The National Weather Service, heavy snow requires proper equipment. A two stage snow blower is built for these tough jobs. It won’t quit when the snow gets deep.
Key Parts of a Two Stage Blower
Let’s look at the main components. Knowing these parts helps you understand what’s a two stage snow blower at a glance.
The auger is the most visible part. It’s the wide metal spiral across the front opening. Good augers have rubber paddles to protect paved surfaces from scratches.
Next is the impeller housing. This is the chamber where the second stage happens. The impeller itself looks like a metal fan with curved blades inside this housing.
The discharge chute directs the thrown snow. It’s usually made of durable plastic. You want one that rotates a full 180 degrees or more for maximum control.
Most two stage models have powered wheels. This means the machine drives itself forward. You just guide it while it pulls itself along. This is a huge help on big properties.
The engine provides power for both stages. Gas engines are common for their raw power. But electric start features make cold morning starts much easier.
Controls vary by model. Look for easy-to-reach levers for speed and chute direction. Some have heated hand grips which are amazing in freezing weather.
Skid shoes adjust the clearing height. They let you set how close the auger gets to the ground. This protects your driveway surface while getting maximum snow removal.
When You Really Need a Two Stage Model
Not everyone needs this much machine. But for some situations, it’s the only tool that makes sense.
Do you get snow over 8 inches deep regularly? That’s the breaking point for single stage blowers. A two stage model eats through deep snow without slowing down.
Long driveways or big parking areas need this power. Clearing 100 feet of heavy snow with a small blower takes forever. The two stage design cuts that time way down.
Wet, heavy snow is another reason. The kind that feels like concrete when you shovel it. Single stage blowers choke on this stuff. The two stage system powers right through.
If you have a gravel driveway, listen up. Two stage blowers with proper skid adjustment won’t throw rocks. The auger sits high enough to avoid picking up gravel.
According to CDC guidelines, heavy snow removal risks heart strain. A powerful blower reduces physical effort. This is safer for many people.
Commercial properties almost always use two stage models. Think shopping centers or apartment complexes. They need reliability and speed that smaller machines can’t provide.
So what’s a two stage snow blower’s best use case? Any situation where snow is deep, heavy, or covers a large area. It’s the heavy-duty solution for serious winter problems.
Two Stage vs Single Stage Snow Blowers
This is the big comparison everyone should understand. The choice between these types affects your whole winter.
Single stage blowers have just one moving part. A rubber paddle both collects and throws the snow. It’s simpler and usually cheaper than two stage models.
Two stage blowers have the auger-impeller combo we discussed. This gives them more raw throwing power. They can launch snow farther than single stage units.
Clearing width matters too. Single stage models are often narrower, around 18-21 inches. Two stage blowers can be 24-30 inches wide or more. You clear more ground with each pass.
Snow depth handling is the biggest difference. Single stage blowers work best under 6-8 inches. Two stage models can handle 12 inches or more without trouble.
Surface type is another factor. Single stage blowers need smooth surfaces like asphalt or concrete. Two stage models with adjustable skids can work on gravel or uneven ground.
Price reflects these differences. You’ll pay more for a two stage snow blower. But you’re buying capability that a single stage just can’t match.
Think about your typical winter. Light, fluffy snow a few times a season? A single stage might work. Heavy, frequent snowfalls? That’s two stage territory for sure.
Benefits of Choosing a Two Stage Blower
Why pick this type of machine? The advantages are clear once you understand what’s a two stage snow blower designed to do.
First is pure power. These machines move snow that would stop other blowers cold. I’ve cleared 18-inch drifts that would have required a plow truck otherwise.
They save you time. The wider clearing path and self-propelled drive mean faster cleanup. What takes an hour with a small blower might take 20 minutes with a two stage.
Less physical strain is a huge benefit. The machine does the hard work of breaking up and throwing snow. You just steer and control the chute direction.
Better handling of varied snow types matters. From light powder to wet slush, a two stage blower adapts. You don’t need different tools for different conditions.
Durability is another plus. These are built tougher than single stage models. The metal augers and stronger engines last for many seasons with proper care.
The Occupational Safety and Health Administration notes that proper equipment reduces injury risk. A two stage blower’s design minimizes the need for pre-shoveling or manual breaking of ice.
Finally, there’s the satisfaction factor. There’s nothing like watching a two stage snow blower chew through a big drift. It turns a hard job into something almost enjoyable.
Step-by-Step Guide to Using Your Two Stage Blower
Using these machines isn’t hard. But following the right steps makes everything work better and last longer.
Start with preparation. Check your fuel level if it’s gas-powered. For electric start models, make sure the battery is charged. Clear any large objects from your path first.
Adjust the skid shoes for your surface. For paved driveways, set them low. For gravel or uneven ground, raise them up. This prevents damage and avoids throwing rocks.
Start the engine and let it warm up for a minute. Engage the auger first without moving forward. Make sure it’s spinning freely and throwing snow properly.
Then engage the drive system. Most models have separate controls for auger and drive. Start slow until you get the feel of the machine’s power and handling.
Overlap your passes slightly. This ensures you don’t leave strips of snow between paths. The wide clearing width makes this easy to do efficiently.
Direct the discharge chute away from buildings, cars, and walkways. The snow gets thrown with force, so aim carefully. Nobody wants a snow shower through their window.
When you’re done, let the machine run for a minute to clear any remaining snow from the auger housing. This prevents ice buildup that could jam the mechanism later.
Common Mistakes to Avoid
Even experienced users make errors. Knowing these common mistakes helps you avoid them from the start.
Going too fast is a frequent error. The machine has power, but rushing leads to missed spots. Take steady, deliberate passes for the cleanest results.
Not adjusting skid shoes for surface changes causes problems. Going from pavement to gravel without raising the skids throws rocks. This can damage property or the blower itself.
Forgetting to change the chute direction annoys neighbors. That snow has to go somewhere. Plan your throwing pattern before you start to avoid re-clearing areas.
Using the wrong fuel mixture in gas models hurts the engine. Always follow the manufacturer’s instructions. Most two stage snow blowers use regular gasoline, but check your manual.
According to Consumer Reports, proper maintenance extends equipment life. Neglecting end-of-season care leads to starting problems next winter.
Trying to clear too deep at once can stall the machine. For very deep snow, take half-width passes or clear in layers. Let the two stage system work efficiently.
Ignoring unusual noises leads to bigger repairs. If your two stage snow blower starts making new sounds, investigate immediately. It’s usually cheaper to fix small problems early.
Maintenance Tips for Long Life
Taking care of your investment ensures it runs well for years. These maintenance steps are simple but important.
After each use, clean off any packed snow and ice. Pay special attention to the auger and impeller areas. Let the machine dry completely before storing.
Check shear pins regularly. These are designed to break if the auger hits something solid. Replace any that are damaged to protect the drivetrain.
