Yes, you should winterize a snow blower before the first storm hits. Learning how to winterize a snow blower properly keeps it running strong all season and stops big repair bills later.
I see it every year. People pull out their snow blower on a cold morning. They yank the cord and nothing happens. The engine just coughs and dies.
This is a huge headache you can avoid. A little prep work now saves you a ton of trouble later. I’ve been doing this for years on my own machines.
I’ll walk you through the whole process. It’s easier than you think. You just need a few basic tools and an afternoon.
What Does It Mean to Winterize a Snow Blower?
Let’s break this down first. Winterizing is just getting your machine ready for hard work.
Think of it like a check-up before a big race. You want everything in top shape. You don’t want it to break down in the middle of a storm.
The main goal is to stop fuel problems. Old gas turns into a sticky gel. This clogs up the tiny parts inside your carburetor.
You also need to check all the moving parts. The auger and the drive system take a beating. They need to be free and well-oiled.
Learning how to winterize a snow blower means doing these checks. It’s a simple routine. Follow it and your machine will thank you.
According to Consumer Reports, proper maintenance extends the life of outdoor power equipment. It’s a smart habit to build.
Why You Must Winterize Your Snow Blower
You might think you can skip this step. I get it. Life is busy. But trust me on this one.
A non-winterized snow blower will let you down. It will happen on the worst possible day. The forecast calls for a foot of snow.
The real cost isn’t just the repair. It’s the stress and the back-breaking shoveling. That’s a terrible way to start your day.
Fresh fuel burns clean. Stale fuel leaves nasty deposits. These deposits can ruin your engine over time.
Knowing how to winterize a snow blower prevents this. It’s cheap insurance. The small effort now pays off big later.
The Environmental Protection Agency (EPA) notes that small engine care reduces emissions. A tuned machine runs cleaner.
Your future self will be so grateful. You’ll start the engine with confidence every single time.
Gather Your Tools and Supplies First
Don’t start the job until you have everything. Running to the store mid-job is annoying. Here’s your shopping list.
You need fresh gasoline. Get the ethanol-free kind if you can. Ethanol attracts water and causes problems.
Grab a fuel stabilizer too. This is a liquid you mix with your gas. It keeps the gas from going bad for months.
You’ll need a socket set or wrenches. Check your owner’s manual for the right sizes. Usually, you need a spark plug wrench.
Get a new spark plug and a new oil filter. These are wear items. Changing them is part of learning how to winterize a snow blower.
Have some engine oil on hand. Use the weight recommended in your manual. Don’t just guess on this.
Finally, get a grease gun and some lubricating oil. The auger shaft and chute control need grease. The cables need light oil.
Step 1: Deal With the Fuel System
This is the most important step. Bad fuel causes most starting problems. Let’s fix it for good.
First, run the engine until the fuel tank is empty. Do this outside where it’s safe. Let it use up all the old gas.
If you can’t run it dry, you need to siphon the old gas out. Use a hand pump or a turkey baster. Get every last drop you can.
Now, add your fresh gas. Mix in the fuel stabilizer right away. Follow the directions on the bottle for the right amount.
Run the engine for five minutes after adding the new mix. This pulls the treated gas into the carburetor. It coats all the internal parts.
After you run it, turn the fuel valve to “off” if your model has one. This is a key part of how to winterize a snow blower. It seals the system.
Let the engine cool down completely. Now you can move on to the next steps. The fuel system is protected.
Step 2: Change the Engine Oil
Old oil gets dirty and acidic. It can damage engine parts over the winter. Fresh oil protects them.
Run the engine for a few minutes first. Warm oil flows out much easier. It drains more completely.
Find the drain plug on the bottom of the engine. Place a drain pan underneath it. The pan should hold more oil than your engine holds.
Unscrew the drain plug carefully. Let all the old, black oil drain out. This might take a few minutes.
While it drains, remove the old oil filter. Use an oil filter wrench if it’s stuck. Wipe the area clean where the filter seals.
Screw on the new oil filter. Hand-tighten it first, then give it another quarter turn. Don’t over-tighten it.
Put the drain plug back in. Now fill the engine with new oil. Use the dipstick to check the level. Don’t overfill it.
Step 3: Check and Replace the Spark Plug
A weak spark plug makes starting hard. Cold weather makes it even harder. A new one gives you a strong spark every time.
Locate the spark plug on your engine. It’s usually on the side. It has a thick rubber wire connected to it.
Pull the rubber boot off the plug. Use your spark plug wrench to unscrew the old plug. Turn it counter-clockwise.
Look at the old plug’s tip. Is it black and sooty? Is the electrode worn down? If yes, you need a new one.
Check your manual for the right plug gap. Use a gap tool to set the new plug correctly. This space is critical for the spark.
Screw the new plug in by hand first. This prevents cross-threading. Then tighten it with the wrench until it’s snug.
Push the rubber boot back on until it clicks. This simple step is vital when you learn how to winterize a snow blower. It ensures a reliable start.
Step 4: Lubricate All Moving Parts
Snow and ice are tough. Metal parts need slick grease to fight the friction. This step keeps everything moving smoothly.
Find the grease fittings on the auger shaft. These look like small nipples. Your grease gun nozzle snaps onto them.
Pump grease into each fitting until you see fresh grease squeeze out. This pushes out the old, dirty grease. Wipe off the excess.
Check the chute rotation mechanism. Does it turn easily? Spray some silicone lubricant on the pivot points. Work it back and forth.
Look at the control cables for the chute and auger. Where the cable goes into a sheath, add a drop of light oil. This prevents rust and binding.
Don’t forget the wheel axles or tracks. A little grease here prevents squeaks and seizing. The Occupational Safety and Health Administration (OSHA) says keeping tools maintained is a key safety practice.
Walk around the machine. Move every lever and control. If anything feels stiff, lubricate it. Your goal is smooth, easy operation.
Step 5: Inspect the Belts and Skid Shoes
Belts drive the auger and the wheels. Worn belts can snap under a heavy load. Let’s check their condition.
Refer to your manual to find the belt covers. Remove any screws or clips holding them on. Be careful not to lose the hardware.
Look at the belts. Are they cracked or frayed? Do they look glazed and shiny? If you see damage, replace them now.
Press on the belt with your thumb. There should be a little give, not much. A belt that’s too loose will slip and burn up.
Now look at the skid shoes. These are the metal or plastic pads on the bottom sides of the auger housing.
They control how high the blower sits. If they’re worn down, the housing scrapes the ground. This damages your driveway and the machine.
Replace them if they’re more than halfway worn. This is a smart part of how to winterize a snow blower. It protects your investment.
Step 6: Do a Final Operational Check
You’re almost done. Now let’s make sure everything works. Do this before you put the machine away.
Turn the fuel valve back to “on”. Set the choke if your model has one. Pull the starter cord slowly a few times.
This primes the engine with fuel. Now start it up. It should fire up within a few pulls. Listen to the engine run.
Does it sound smooth? Or is it sputtering? A smooth run means your fuel system is clean. A sputter might mean you missed some old gas.
Engage the auger control. The auger should spin quickly and freely. Listen for any strange grinding noises.
Try the drive control. The machine should move forward and back easily. Test the chute rotation and the deflector.
Turn everything off. Let the engine run out of gas again or turn the fuel off. You’ve now completed the core steps on how to winterize a snow blower.
Common Mistakes to Avoid
People get in a hurry and skip steps. This leads to problems. Let’s go over the big mistakes.
The number one error is leaving old gas in the tank. This is the main reason snow blowers fail. Always use fresh, stabilized fuel.
Another mistake is forgetting the oil change. Dirty oil sits in the engine all off-season. It can cause corrosion inside.
People often ignore the spark plug. They think if it starts, it’s fine. A worn plug strains the starter and gives a weak burn.
Don’t forget to lubricate. Dry pivot points freeze up in the cold. You’ll be yanking on a frozen chute when you need it most.
Storing the blower outside is a bad idea. Moisture causes rust. Store it in a dry shed or garage if you can.
Following the full process for how to winterize a snow blower avoids these issues. Take your time and do it right.
Tips for Easier Winterizing Next Time
Want to make next year’s job a breeze? A little organization goes a long way. Here are my pro tips.
Keep a maintenance log. Write down the date and what you did. Note the oil type and spark plug number.
Buy your supplies at the end of winter. Oil, filters, and plugs are often on sale then. You’ll save money and be ready.
Take a picture of your machine’s model and serial number. Keep it on your phone. This makes buying the right parts simple.
Store your tools with the snow blower. Put the right socket, spark plug wrench, and funnel in a small box. Tape it to the handle.
