I had to jump in the jeep and go get one of my plow trucks from my office because I couldn't fix the snow blower, I split the front unit from the rear chassis and the bearing in the second stage fan is very tight, not sure what happened to it, but its under warranty so I will drop it off and let them deal with it, I thought it was just the belts, but its more than that, the seized bearing cooked the belts.... sucks, but I plowed a path, bad part is now I have to shovel out my garages since that is the only place to plow the snow, bad driveway design for sure {even though I designed it, I suck, appearance over function...
