My 17 HP Kohler Courage was run with no oil in it for a about 1 Minute. After I figured it out I put oil in it and it ran great for a couple weeks with no problems. It did after 2 weeks throw a rod and destroyed most of the inner workings. It is cheaper to get the 20 HP Kohler Courage than a 17 HP (seems like they don't make them anymore?). Is there anything else I need to get to make sure it works with my 17 HP motor setup? Any help is greatly appreciated!!!!
