Hey folks. Need some help with a used 3pt Snowblower that I just bought. It is a 64" Pronovost Puma model, being powered by a B3200 Kubota. It seems to be in very good shape, not a lot of paint is gone, auger and impeller turned fine when I bought it. Problem is that when I hooked it up and turned it on, the shear bolt on the PTO shaft let go.
I figured out that the impeller was hitting the inside of the drum in a spot, maybe 5" long. I don't remember it doing that when I bought it. I figured I would just let her run for a few minutes to wear away the metal, or perhaps bend the metal of the drum enough to give it clearance.
Well, I ran it for about 5 min and it is still doing it. Why would it do that, especially since it turned fine when I bought it? I winched it off the trailer with my atv when I got home, but it was very slow and controlled. I don't know what else to do besides run it. The impeller shaft has no play in it. The spot that rubs is on the bottom of the drum, so I thought maybe it was sagging down, but I don't think so.
On a side note, changing the gear oil in these is no fun! Had to use a suction gun, as there is no drain....I'm sure I didn't get it all out. Oh well, there isn't much to these blowers, hopefully everything will be fine.
I am traveling for a few days, but look forward to the replies you folks always give...thanks for your help.
