Hi everyone. New to the board. Glad to be here. I picked up a model 190-350 snowblower real cheap and now I'm starting to think about tractors. Which model tractors will this unit fit? The mounting rails are 11" apart. I would like one as powerful as possible. I'm assuming I need a PTO for transmitting power from the engine to the blower. Anything else that I need to think about? Thanks very much for the help. -Brian.
