.. I commend Ventrac for making the videos they do, just wish they were realistic. Any of those mowers could climb those hills mowing nothing but dust, add 6-8" of wet grass which is more like average mowing conditions for hillsides. IMO only the kubota 32.5hp gas has the power to run the 7 ft deck and climb hills in heavy growing conditions. The kubota 25hp Diesel shouldn't be in the test as it isn't adequately powered for steep hills and a 7ft deck,it should be limited to the 60" deck on 30 degree hills... Kind of misleading IMO.
