Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Well........finally getting around to starting a thread on this impeller mod for the snowblower.  Perhaps a little late in the season, but it will give us something to talk about!  In light of the recent thread about plastic liners, I thought I should get this started.

I have to admit that when I first heard of this, I was a little skeptical at first.  Sounded interesting but as with most mods, they are usually more hype than improvement.  Some had been telling me about it and said that it made a real improvement.  Yeah, right.  I checked out the web site and, have to admit, I was being drawn in.  Clarence lives in the same city as I do, so this gave me some more interest in checking it out.  Still back burner though.

So.........one day we are out doing driveways and this occasional client that lives across the street from my client sees that I am having a little trouble with the slush getting plugged up in the machine.  He tells me that he just got the kit installed on his machine and is going to give it a try.  Now I know how his machine performs usually, as I have seen him do his driveway  many times over the years, so this should be interesting.  Well, the next thing I know, is that I almost wet myself!   He was blowing that slush out of his machine like it was being shot from a cannon!  Now we all know that slush usually goes about 2 feet, so seeing  this stuff fly 20+ feet was nothing short of unbelievable.  We tried some snow with it and it was going 30-40 feet.  Normally his machine throws about 20-30 feet.  By the next day, I was over at Clarence's and getting it installed on one of my machines, to check it out for myself.  I have NEVER looked back.  Now, ALL of my machines have been fitted.  My favourite machine is an MTD Pro 13/33 (1986) , with the 13 hp B&S engine, and it will honestly throw snow 50-60 feet!    The Ariens and other MTDs have been fitted too.

ABSOLUTELY no snow or slush will slow down this kit! EVERYTHING that goes in, will come out!  EXCEPTIONS include: newspapers and extention cords!  Havn't picked up a squirrel yet!

Most kits now have roughly 2000 times on them now and the belting is holding up quite well. I see no need for any replacement yet.

Installation will require medium skill, I guess, as you will have to remove the chute and drill the impeller to install the kit.  You are working through the opening for the chute. 

For the first several times you use your machine, the sound will be quite different as the rubber will be dragging slightly on the housing until it gets worn in.  THAT MEANS THAT IF YOU CAN'T HANDLE THE PAINT COMING OFF OF THE IMPELLER HOUSING, THEN THIS KIT IS NOT FOR YOU!  It will make the metal quite shiny, I must say.  BUT, if that is not a big deal for you, then the perfoermance upgrade will be more than a fair trade off.  Other than the paint coming off, the metal is not being worn out.  With all the use that my machines get,  they are still in fine shape.  With typical homeowner use, you should still get 50 years out of your machine.

So........which machines are likely candidates?  I would say every 2 stage machine out there, with the exception of Hondas and Yamahas.  They already have a tight gap between the impeller and the housing and would not show any improvement.

Clarence is a super guy and I send all of my equipment to him now, (that I can't fix) for repairs.

Hope this helps.

Got any questions............fire away!

PS Thanks for the push.............Fred!

Richie,

Thanks...I didn't measure the impellers but figured the kit wound't work as well with the redesigned Toros.  As is, it does a decent job of throwing slushy stuff so I'll keep it the way it is.

I saw this mod online and he wanted $30 plus $8.95 shipping. I went to my local Family Center (tractor/farming store) and purchased a foot of hay baler belt and the brackets and bolts for $6.41.

I had to replace the belt on my MTD 5/22 anyway so I took off the 6 bolts that hold the auger body to the body. I took off the chute and placed the whole unit on a bench. I used a long board to stick through the auger which held the impeller in place.

The whole process was quite easy and took about 40 minutes. The trick is sharp drill bits. I started with a small bit to get the two bolt holes lined up then used the larger one to finish the hole to the correct size for the bolts.

Fired up the blower and let the rubber wear to the size and shape needed.

Now I await the first snow. of course, none in the forcast. :)

PS The gap on my impeller was over a half inch!! No wonder it plugs a lot. Cant wait to try it.

Ischafroth,

   >>hay baler belt<<, I don't know the stuff but it sounds perfect and strong.

   I've had a number of the MTD 522's around and they are nice.   Arm extenders on that machine would be interesting.  Please come back and update how it worked.

I had that kit once on my blower and it shoot snow good but it takes much power on engine and gear case so far it gives a premature used parts. I dont recommended, why manufacture doesn't put them on their machine? well security question: if you grab a piece of rock it will jammed between the impeller and the auger and the engine will quit but with the kit it will go away somewhere on a car windshield or whatever in a somebody faces ??? think about it

Well I posted that no snow was in the forecast.  We were supposed to get a dusting here in Iowa and Minnesota shared with us instead!  We got 8 inches and 50mph wind gusts. ugh.

Fired it up yesterday morning and now I have a new problem with the snow blower.  My neighbor's porch now has snow in it!!  wow does it throw the snow!!  The true test will be wet snow but its way too cold for that.  We are having a high of 11 today.

Anyway, it blows the snow farther than it ever has.  very cool and well worth it so far.

PS Hay baler belt is a durable rubber with a layer of string all through it so it never gets too hard in cold but is very very strong.

I am on year three of using the Clarence Impeller Kit.  My machine is a Craftsman 28" with a Briggs engine.  Some people responded to a YouTube video I put up of the thing in action saying the kit causes added stress on the gears and will cause premature wear.  So far, knock on wood, I have had NO problems.  Let me tell you, that beast throws the snow clear into the neighbors yard!  And the comments about slush are absolutely true - the thing just fires that end-of-driveway slush out. 

My review is a thumbs up for the kit!

After reading several posts about the Clarence Impeller Kit, I decided to install one on my 2007 Ariens 926LE Deluxe snowblower.

What motivated me to do so is that my snowblower has outstanding performance in powder snow, but on the other hand, its performance in wet snow is to say least very poor i.e. throwing distance of 3 to 4 feet and a lot of jamming. The impeller gap to the housing is not uniform; it is about 1/4" at the center and about 3/8" at the edges of the impeller.

So last weekend I installed the 4 blade / 3” wide kit (the 3" wide kit is perfect for this machine as it just fits the flat section of the impeller) and it took me about 2-3 hours to complete the installation. I started by positioning the impeller at 90° and I used a punch to mark the centre of the middle bolt so that the drill bit would not slip, then I installed the blade, and then used the blade as a guide to drill the remaining holes. Everything went smoothly.

I could not wait to test the kit and fortunately we got 4" of wet snow 3 days later. The results are outstanding: this machine now throws wet snow, slush and water!!! at about 40 feet. This is impressive. I was scared to throw snow on the neighbour's driveway and car. So I'm very satisfied with the kit.

While reading other posts I noticed that some concerns have been raised about this kit and I would like to provide my opinion.

One of the main concern is that this kit will produce premature wear on the motor and belt. I do not believe this. With this kit installed whatever snow that comes in the bucket goes out. Before installing this kit, wet snow accumulated until a jam occurred and engine almost stalled. My conclusion is that there is a lot more stress on the impeller and belt when the snow accumulates until the engine almost stalls. Less snow going out = more show in the bucket = more stress on the machine. With the kit installed, the engine is forcing, mainly due to weight of the wet snow, but is never near to stall. This answers this concern by itself.

The second concern is that in the case one blade of the kit brakes then it would be ejected, causing potential injuries. I do not think that is worst than blowing pieces of ice that are present at the end of the driveway. Also for this problem to happen all three bolts would need to break at the same time.

The last concern was that small rocks could jam between the impeller and the housing. I think that with this kit installed small rocks can not go between the impeller and the housing as there is no more gap. Rocks will simply be ejected with the snow.

The kit I installed on my old JD TRX26 a couple years ago turned it into a snow hog!!!!   I love the "new" old machine.....
