My choice is now done and I will sign my new mower maybe tomorrow or tuesday. I know exactly wich mower mower I want. It will be my second ztr with this dealer. My only problem is the engine! I have to choose between the 30hp kohler or the 27 kohler. Wich one I should get?? 30 hp would be the best for my need but I'm not sure about this engine...27hp is very good from what I have heard but I'm not sure if it will be enough.. Help me! It will be a 60"deck on this mower.
