Hi guys I have a Kubota 2674 snow blower . It worked great last winter. I took it off after winter and placed it outside on a skid. I reconnected this weekend and the impeller looks like it’s jammed to the lower housing. When I engaged pto it stalled the tractor. It was moving freely last time I used it in February. A mystery . Could a bearing have been failing and take in water and then freeze causing it to jam ?
