More than anything, I am worrying about trashing the main drive belt from the pto to the front angle gear pulley in short order. Time will tell! :)

 

I did have to go from one belt to two on the PTO. One belt in heavy or hard packed snow couldn't take the load and would break. If it was wet the one belt would slip and the chute would load up. With two it has been no problem at all.

not to hijack the original thread, but how did you make double pulleys? My PTO has two different sized pulleys on the engine. How did you do it?

That's a good question! I'll have to look at it and take a couple pictures I guess. Old memory ain't what it used to be.  :(

Oh by the way when I made this post I was using the smaller blower. I have since then landed a deal on a haban blower and am now rethinking the whole idea of the pulley size increase. Its a bigger blower and from what I hear it even blows better so I am going to use my standard engine pulley until I feel the difference.

The wheel horse was the bigger of the two blower before.

OK I have a photos for you. Had room for double sheave pulleys and machined a wide idler pulley. Don't recall if I had to do anything with the shafts or not.

Yes it is but well worth the effort. Hope you can come up with something similar. 

Another thought, If you have room for larger diameter pulleys that will help. If there is room for just one you could go with a wider notched belt and that would help also.

Thanks for posting that! My main drive pulley is a part of the electric clutch pto, So I am going to have to modify my pto to make it work. It's nice to know there are double pulleys available, as well as the tensioner roller.

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.
