Two-Stage Snowblowers - Impact on Concrete Driveway and Exposed Aggregate
Original Message   Oct 6, 2008 5:56 pm
Hello!

This is my first post and I would appreciate any thoughts you might have based on your experience with two-stage blowers.

We built a house two years ago that has a concrete driveway (about 120' long) with an exposed aggregate border. The aggregate also forms the walkways for all three front entry doors and the garage apron. I have been using a Toro single stage for the last two years and have struggled at times with the amount of snow we receive here. We had over 100" last year and I felt every bit of that. We live in a lake effect snow belt so get blasted quite regularly. Given the direction of the prevailing winds the snow accumulates around our three car garage and entry areas and can be as high as 18" or more. I find with the single stage Toro that I am reblowing the snow repeatedly (as the turnaround area is longer than the snow can be blown) just to get it cleared.

After two years of this I've decided that a two-stage would be a better answer to this problem. However, my initial forays into local dealers have turned up several issues. First of all, we have an exceptionally nice (expensive) concrete driveway and several dealers have warned me that the skid shoes on a two-stage blower can scratch the driveway with repeated use. They've also indicated that the scraper blade could be a problem with the exposed aggregate. I've been abble to find a polycarbonate alternative for Ariens but have had no success with the scraper blade. As yet, I have been unable to locate non-scratch skid shoes or scraper for the Simplicity I'm interested in.

I am now also concerned with about a two-stage from a clearance perspective. If I set the blade too high (to avoid scraping) I could be leaving a significant residue on the blown surfaces. This was not an issue with the single stage Toro. This would not normally be a problem but I sold my SUV this year in favor of a rear wheel drive car. While I've ordered winter tires and rims, I'm concerned that leaving too much snow on the driveway will result in a slippery surface or ice buildup that could become problematic. My driveway has a 15 degree slope that adds to the problem. One dealer suggested that I use salt to eliminate the remainder but I believe the landscaping around the driveway would be adversely affected by this solution.

I guess I'm interested in two things. First, does a two-stage blower leave scratch marks on a concrete driveway? (from the skid shoes and/or scraper) And second, how does a two-stage handle a significant amount of exposed aggregate? Is the only solution raising the blade to a level where a significant amount of snow is left behind?

I was really looking forward to a two-stage blower but now am not so sure. The problems they impose may be larger that the challenges I currently experience with the single stage Toro.

Thanks in advance for your thoughts and assistance.

PS I skimmed all threads in the forum back to 2005 and could not find an answer.

A cab shifts the center of gravity, as you indicated, and in practice, acts as a sail when the environment is windy. Some cab kits come with nose weights, others recommend or require them.

However, the comment was "lift up on the handlebars". Key word was "Up".  That is because the Ariens grips are 4" further rearward, and pointed slightly down. Force on them overwhelmingly goes to rotating the nose over the rear wheels. Lifting up is unloading the rear wheels more than it is loading the nose.

On the Husqvarna the grips are pointed about 18° up to the front. the rear of the grip is also 1.75" higher. The Simplicity/Deere is similar, but not higher. Pressing down on them loads the rear wheels and minimally unloads or doesn't unload the nose.

I'm not sure why a solution is looking for problem, but I'm not going to hijack this thread. 

Feel free to add to relevant discussion to the original topic.

No problem. Better late than never. Like I said before, I've changed the shape of my poly skids because I suspect my skid design may ride up on snow more readily because of the larger footprint, and potentially wander more. I suppose it's a tradeoff to lessen the pounds per square inch loading on concrete/pavers to prevent damage to the surfaces. Your information is helpful for me to have somewhat of a basis to dial in the shape. Thanks. Looking forward to hearing from you with new findings.


I think you could make the skids longer, but try to keep them as narrow as possible. 

If the stock metal ones cut through the snow better, I'll look at cutting down the poly skids to make them narrower and still get some good use out of them.

The blower in question is an '06 Craftsman (MTD) 928 w/ Clarence kit (which did help quite a bit).  It didn't matter which way I pushed on the handlebars (up, down, sideways, caddywumpus, etc.) the poly skids seemed to ride up on snow much more than the stock skids.  The cab is an Ariens and works wonders for keeping the snow off my neck, but it did quickly develop a crack in the plastic windshield where it goes from vertical to horizontal (must be the -20 temps I usually blow in).  I actually like being able to push down on the handlebars to lift the bucket so I can easily make 180-degree turns (got the dual finger triggers that unlock either wheel).

I had posted here a year or two ago about how my driveway had brick inlays that played havoc on the skids and scraper bar (needed to remove as much snow as possible since it has a good long slope - dangerous with ice).  I got the bricks torn out this last summer and 5" concrete put in place for a nice smooth driveway (~3000sf) - looking forward to blowing snow this year!

Brad,  It's pretty new... but you might want to take a look at the NEW Roller-Skid replacement skid that it just now hitting the market.  Instead of a steel or plastic skid that is designed to grind down... this gadget ROLLS.  It was originally designed to simply make the job easier, but ended up having several other important advantages.  There is a pretty nice little installation sheet that is included that does a pretty cool job of showing you how to set the scraper bar at the correct height when installing the Roller-Skids.   Because it's made of 1/4" thick 30% Glass -Filled Nylon it is extremely durable and because it ROLLS it doesn't scrape and scuff your driveway and walkway surfaces... and it won't leave rust stains on your garage floor.  Even the axles and hitch pins are made of stainless steel!  You can see a short video at https://sites.google.com/site/rollerskid/.  You can buy them at SnowBlowersDirect.com  http://www.snowblowersdirect.com/Raftery-Design-1250/p5415.html  I understand they will begin shipping around November 1st.

If anyone has these I'd like to know more. my metal skids are already worn out on one side, gotta be flipped. I just wonder how durable these are as the steel skids wore down quite a lot in just one winter. I guess scraping tar for hours at a time will do that.

Rafdog,

The design looks promising.  Clean and simple.  Any chance you will make this product to fit a Honda snowblower?  It takes 2.36" bolt centers.

On a side note, I'm not sure if you read the terms of use, but this self promotion may not be allowed.  Just saying...

Just thinking out loud... but it might be easier to simply drill an additional hole 3" from either the front or back hole on the side your auger box and mount the Roller-Skid.  In my humble opinion... I believe you will be happy you did.

4. Fits machines with 2-3/4" and 3" bolt centers

The Roller-Skid fits machines with both 2-3/4" (MTD, Troy-Bilt, etc.) and 3" (Ariens, Toro, John Deere, Craftsman, etc.) bolt centers.

 DavidNJ and JimmyM,

Drill a new hole in the side of your auger box on a 3" center and bolt on some Roller-Skids!   It'd be a whole lot easier than machining a big skid from an expensive block of plastic... that's eventually just going to wear down anyway.  Go to SnowBlowersDirect.com > Accessories > Non-Abrasive Skids.  $29.99

Yes, easy to do.  However, I'm not all comfortable putting additional holes in my snowblower at this point to try out this new roller skid.  I will have two holes near each other which will be weakened unless I reinforced with a backing plate on the inside and outside of the bucket. 

Your invention seems like it will work, I just wonder how long it will last.

PS I skimmed all threads in the forum back to 2005 and could not find an answer.

I just had a stamper concrete driveway installed and also have the problem of scratching with the blower. Luckily I tried the blower out on the last 2" snowfall on one section toward the side and found some scratches where the skid shoes come in contact. We have the bluestone effect pattern and it is also a bit uneven so even if I set the scraper blade up the skids do damage. I've just purchased roller skid shoes but this still does/did not solve the problem entirely as the scraper blade still comes in contact with the concrete... I don't want to do double duty (sweeping/shoveling after cleaning) so I did some heavy drinking... oops thinking and came up with an idea that works perfectly, or at least better than leaving a half inch of snow behind. I have some rubber backed flexible flooring left over from a bathroom install and cut a strip approximately 1/2 to 3/4 wider than the scraper blade... aligned the holes (drilled to prevent weakness) and put it behind the blade. Now there's a 3/4 inch sweeper that clears the snow without the metal coming in contact... mind you, it isn't perfect but it's way better than leaving the 3/4 inch of snow behind from the start. I also cut a few extra as it will wear out after usage...
