Lookin good John! Be fun to see it after a good snow fall. 

My wife said the same thing, we have some falling now its the heavy  granular stuff.  We are letting this fall and build up as much as we can before dark then plan to make a quick run around. This time I will be playing ahem working on the horse so will be running the 2nd snow blower to make clean up quicker instead of trying to make her mounds with the plow....lol

 

I am sure we will get womped on  with a good one this year so if I don't get any video of this one I'll make sure to get that one when it comes.

Got to finally try out "Lucy" today, we did not get much snow but what we did get was that wet heavy stuff.  To test out the distance I did pack some nice wet heavy stuff in front of it with the plow tractor and let my wife shoot it off the bank. 

 

I will say I am more then impressed with the modifications , this thing throw further then any single stage snow blower I have used and with the new engine you can barely tell your even running into anything. I have the rpms maxed at 3400 rpms just a smidgen higher then max output of engine just where the power curve starts to drop so when you hit the snow it falls right into the sweet spot of the power curve.

We will give it another test when we get some real snow. But can tell already we are happy with the modifications. 

Well done, John. I still haven’t solved the same problem generally, hope that your inspire will influence to me. Best wishes

Upd. Sorry, didn't see the date. How it's going?

Unless I can figure out how to post videos so people can see them you will have to wait a few more years, but lets see if this works.

I tried to find the problem you are referring to but not sure if I missed something or not.

Ok I have read though this post and have realized that I have done several modifications to the Haban blower and tractor though the years that I never got to mention. 

 

I will start off with the Sears tractor first, It has a Subaru EX40 14hp repower. Reason for this is I wanted something a bit more modern but refuse to buy Chinese knock off engines. I wanted something with quality so was only considering a Yamaha, Honda, or Subaru engine. Subaru had that 1 extra hp and a better charging system so I went with that. Along with the engine swap Increased the size of the attachment drive pully by 1/2 inch but lowered the engine RPM's to 3400 max instead of 3600. 

 

Second was the Haban blower. Haban's come with an odd chain and sprocket that cannot be purchased any longer in other words NLA. So I had to come up with a solution. The original chain size is a #41 and finding the right size chain and sprockets in this size is impossible, so I decided to swap both sprockets and chain to a more common size of a #40 often used in go-carts and is a little stronger then the original #41. At that point I found one for the auger that was just 1 tooth larger then the original, so made the gearing lower. The original is a 35T #41 and all I could find is a 36T  #40. So my increase was decreased and I upped the rpms to 3500.

Sprockets available at tractor supply all I had to do was drill bolt holes.

At this point while doing the drive sprocket since it has to be welded on I put new bearings in.

So the past  3 years have been completely trouble free , I have not even worn though the original belt I put on. If not for attachment swapping and oil changes I would say I have done zero work to the tractor.

Don't even bother to bring her close to the garage anymore I am spoiled to know that she will start even in the bitter negative degree temps.

I have had newer, I have had prettier, but this is the best damn garden tractor I have ever owned.
