One of the reasons your snowblower may fail to remove snow efficiently is due to worn-out auger paddles or blades.
When first buying a snowblower, most people aren't aware that it needs regular maintenance. That's why I am here to tell you how to replace snowblower auger blades.
So, without further ado, let's get started.
How To Replace Snowblower Auger Blades
One of the things to know about auger blade replacement is that it will vary based on the brand of your snowblower. So, you need to check the manual for specific instructions regarding replacing the blades or paddles. In most cases, brands recommend replacing them if there's any significant damage or when the paddles have worn out.
Here, I will mainly focus on the replacement of the auger blades or paddles in single-stage snowblowers. That's because the process of replacement is pretty similar for most brands for these machines.
However, things start to differ when you want to replace the blades of two-stage or multi-stage snowblowers. Most of them contain elaborate auger systems that you need to take apart to replace the blades. To be honest, I would advise owners of these machines to visit a certified service center to get the auger replacements.
Now, let's check out how to change auger blades in your snowblower.
1. Remove The Bolts
The first step would be to remove all the bolts that are holding the blades in place. To do this, you'll need to get hold of appropriate Torx bits and a socket spanner to undo the bolts. Some people prefer to start by removing the side bolts and then move on to the middle bolts. But, you should do it as per the instructions in the manual.
2. Remove The Blades
Once the bolts are out of the way, removing the two blades from the housing should be fairly easy. You may just need to move the middle part of the auger to pull out the bottom blade.
3. Prepare The New Auger Blades
When you plan to replace the auger blades of your snowblower, make sure to get a replacement kit manufactured by the same brand. The kit usually comes with all components, including the new blades and bolts to use for the replacement.
Take out the blades from the kit and prepare them by inserting the bushing into the middle holes. Also, note which side of the blades should face the front.
4. Install The New Blades
I think that the best way to install the auger blades is by positioning them on the center mounting plate. Make sure to align the holes and place both the blades into their place before tightening the bolts. Note that while installing the bottom blade you may need to wiggle it into the mountain plate. After the blades are in place, check that they aren't bent in a weird way.
Next, it's time to secure the blades in their position using the new bolts. Start from the middle as it will help to stabilize the blades and keep them from moving. Then, move on to the sides and pay extra attention to securing the blades to the snowblower housing.
At times, securing the side bolts can be a challenge. To make it simpler, use a needle nose vise-grip or pliers to secure the nut at the back of the housing while you slip the bolt into the hole.
Once all the other bolts are in place, replace the middle bolt with a new one. Your snowblower should be running interruption-free after the auger blade replacement.
5. Replace The Scraper Bar
Most snowblower brands I have come across suggest changing the scraper bar along with the auger blades to keep the machine healthy for longer. To do this, you'll first need to unhook the springs that attach the scraper bar to the snowblower housing. Then, use a socket spanner and a wrench to unbolt the scraper bar for easy removal.
After that, you need to install the new scraper bar into its intended position and reattach the spring. Don't forget to replace the bolts, which should secure the bar into position. Just make sure that it lies flush to the ground for hassle-free snow removal.
Final Words
That's everything I had to tell you about replacing the auger blades in your snowblower. Remember to let your machine cool down before replacing any of its parts.
Moreover, I would like to add that if your snowblower is still under warranty, it's best to contact the brand before performing any replacements. And at any point, if the process of auger blade replacement sounds too daunting, don't forget to take help from an authorized repair person.
Until next time, goodbye, and take care!
