Hi, there's one of these for sale near me, non-running, with deck, blower & tiller, all looking pretty rough. I haven't been able to dig up much info about this model, other than that it would be hydro drive and 16 HP. Wondering how the tiller attaches and drives (pto/shaft or belt)(hydraulic lift? sleeve hitch?), and whether this model would be something worth fixing up. Thanks!
