I'm kind of bummed that it grenaded too James,it's not your fault though !--my driveway is long and wide and has killed many a snowblower & tractor in its day..
Maybe I'll come across a parts one someday and get it to work again..
I have not yet taken the gearbox apart--it might be salvageable if I can get that shaft made or find a used one...(rather just bolt on a complete gear box though )..
The blower was actually throwing snow pretty good that day too,and hadn't eaten the belt right away--the rubber paddle impeller mod did help a lot..maybe the drag from the rubber had a role in the early belt failures and the eventual destruction that occoured,I'm not sure...probably just old age and it was its time to fail..
In the meantime I'll probably put a plow on that tractor...
I keep my eyes on CL for a Suburban plow,I should have pursued one that was for sale a while ago close by for 50 bucks..
That 3 stage walk behind snowblower I have in the shed I showed you--one day several years ago I was using that as a last resort to open up the walks and paths,and I when I was blowing thru a deep drift,I heard the engine suddenly rev up like it had no load on it,and I saw something fly off into a snowbank...
I shut it off ,and I heard something sizzling in the snowbank...whatever it was had melted a big hole in the snow,all the way to the bottom...I reached in to grab it and I got burned!--it turned out to be the centrifugal clutch ,and it still had the crankshaft in it..the crank busted off flush with the block!

....
So much for that perfect running engine,I threw it in the shed,and ended up cannibalizing it for parts...(I think I put the flywheel on that Ariens Tecumseh I gave you )..ever notice how well things are working,just before they blow apart ?...
