I got my tractor back today from the dealer, The motor was using about 1/2 a quart an hour. They did a leakdown test and it was at 25%. Bad Rings! You could not see it buring oil but you could smell it on your clothes afterword. It had only 115 hours on it. I am not happy, Kohler refused to pay for amy of it. When I was picking mine up someone was bropping off a Cub Cadet with a 25hp Kohler with the same problem, he as 50 hours on it.
