So today I bought a 1997 Toro Wheel Horse 312-8 garden tractor with a 42" side discharge deck. Very nice, quiet running machine. Think I am going to like it. These tractor's have an excellent reputation too. The Kohler Magnum M12 engine has 1100 hours showing on the working hour meter. I doubt they are real accurate, but still, that is getting up there in the hours. My question is, how many hours should I expect this engine to last? Assuming proper maintenance of course.
