The Case Compacts are Hyd drive,, not hydrostatic,, rear of the engine is a hyd pump,, transmission has Lo and High ranges,, a hyd control valve controls speed in each range as well as braking,, the tiller is driven from the same hyd system, only snow blowers and mower decks are belt driven,, there was a also hyd driven snow blowers and mower decks in later years available,, there was many Case built attachments that are also hyd powered,, Jon no way thats a Demonstrator, look at the rear fender and foot board style,, late model built early 80's, even in the sad shape its in the hyd pto valve alone is worth asking price, then you have sleeve hitch and the tiller,,
