OK just curious about this and would like some input. Friend of mine owns a faily large const. co and was talking to him yesterday about starting the tractor to just let it run and he asked me why? He said that other than the battery he never saw any benifit. He recomended to simply block the clutch and drain the carb and to throw a charge on the battery if it seem to be getting low. Now I have always tried to start about once a month if it wasn't used but now am confused.You know how ya just do things the way ya always did it or was taught and we all know old habits. Some of you mechanics tell me what ya think?My tractors are not really workers just more of the love and hobby.
