Notice thin snow strips left behind even after a long snow clearing session?
The chances are that the scraper blade in your snowblower isn’t working properly. It’s among the many components of the machine that need to be replaced based on its condition and performance at any point in time.
So, to ascertain whether a replacement is indeed required, you’ll need to understand several aspects of its functioning. Don’t worry; I’ll help you with everything.
Role Of The Scraper Blade In A Snowblower
Also referred to as a shave plate, the scraper blade is fixed at the bottom of the snowblower housing to scrape loose the dense, stuck-on layers of snow. This allows the paddles of the machine to remove those layers easily.
The scraper blades on two-stage snowblowers are generally made of strong metals such as steel. On the other hand, single-stage models come with composite or plastic varieties that are relatively weaker.
You can even adjust the height of the scraper blade from the ground to clear more snow. Just loosen the blade hardware below the housings and pull it down as needed. Then adjust the two steel plates or skid shoes fixed to the exterior of the housing, and you’re good to go.
Signs That The Scraper Blade Needs Replacement
The friction resulting from the constant scraping action of these blades causes them to undergo wear and tear and leave more of the snow behind. That’s because the worn portions of the blade won’t scrape the snow down to the paved surface and will leave behind small strips of snow.
Ultimately, you’ll need much more time to get through the job. And that defeats the purpose of using a snowblower in the first place.
So, how will you know when to replace scraper blade in snowblower? Here are some common signs that you must watch out for:
- The scraper blade isn’t removing all the snow at a particular spot even after you’ve adjusted it far down.
- Much of the blade looks worn out.
FAQs
Now, I’ll be answering some commonly-asked questions on scraper blades, which can help you get the most out of your snowblower in the long run.
Yes, you can scrape such surfaces by setting a lower clearance height, provided they don’t have massive cracks or loose stones. Otherwise, a consistent scraping action on the surface might cause the blade to wear out faster.
A scraper blade comes with a blade holder that's either spring-loaded for automatic adjustment or works through manual adjustment. While the former is commonly found in single-stage snowblowers, the latter is an essential part of two-stage models.
So, in case the scraper in a two-stage variant is worn, you will have to reposition it to ensure more effective contact with the clearing surface.
Here’s how you’ll need to proceed to adjust the skid shoes:
Step 1
Keep a spacer beneath the left and right sides of the scraper blade holder.
- Apply â…›-inch thick spacers for clearing paved surfaces
- Apply ½-inch spacers for gravel surfaces
Step 2
Follow this by loosening the hardware on the skid shoes and positioning them against the surface to be cleared.
Step 3
Finally, tighten the hardware again to complete the adjustment.
Some single-stage snowblowers don’t come with the provision of installing skid shoes owing to their different design.
For instance, the design of Toro snowblowers allows you to tilt them forward to pull them through the snow cover. That’s why fixing a skid shoe onto such snowblowers might be counter-productive to its design intent.
Final Words
To round it up, the scraper blades in a snowblower play a key role in keeping your pavements and driveways spic and span. That’s why you shouldn’t skip checking them during your routine maintenance sessions.
On a side note, consider replacing the scraper blade every two months in case you need to use the snowblower extensively. Another point worth mentioning is that in the event of a sudden crack or breakage, you should go for a replacement immediately to prevent further damage.
It’s time to wrap things up now. See you soon!
