I have both the 18 and 20 HP kohler magnun all seems well but I worry about how hot they both seem to run. . The motor blower fans work great and the screen air duct down below is 100% free of debree. Seems as though even only after minutes of running the motor is to hot to even check the oil...
It started out as a 1204 12 HP , I bought it with an 18 HP kohler Hydro later it started smoking at low RPMs so a week ago I had just installed a good low hour 20 Hp Kohler Magnum. Then I installed the new duals, 300 pound suit case weights and modified the cutting deck and installed it again. Built
