Exmark, If you go to the engine chart on your web site and click on the 23hp Kohler (Vertical), it brings up the specs for that engine. The specs list this as a 22hp engine. Is this a 22 or 23 hp engine? Also, the max torque is listed as 38.2 lbs. ft @ 2200 RPM. Could you clear up the horsepower question, and also give the torque rating at 3600 RPM. Thanks in advance for your response!
