All. My brother recently purchased a new 1025r with a 54 inch blower. I suggested he have a steel impeller installed as I have owned two of the blowers and both have had the steel impeller. I find that it greatly improves the implement.
The first blower he had constantly made loud noises and broke shear pins. He went through 10-12 before the dealership was able to come pick it up around the holidays. They found nothing wrong. He looked at my current blower on a 2032r and my old machine (1023e) that my father now owns and determined that the impeller was improperly installed and was grinding/hitting against the actual frame of the blower. The dealership was good; got it in to look at a couple days after and warranteed an entire new unit and impeller.
The new one is doing the same thing. He looked again at the impeller and it appears to be appropriately installed and isn't making contact anywhere on the blower frame. The dealership looked at it and put it into heavier snow and it performed fine. Back at his house it started popping pins again. They called Deere and relayed that the machine needs to be at idle when the PTO is engaged and not at full power.
All this to say that it is still breaking pins. I installed the impeller on my 1023e when I owned it; I am absolutely not a mechanic. My dad assisted who is very mechanically inclined but again not mechanics. Never had an issue. My 2032r had it installed from a different dealer I purchased it from and I have had zero issues. I even found my shear pin in the impeller to be loose when he started having problems and I examined mine.
For clarity the pin that keeps breaking is the pin/bolt on the shaft with the impeller. The auger pins have been fine.
Anyone experience something similar or have any insight on this?
