The model 30-60 exceeded its manufacturer’s ratings at Nebraska tractor tests cranking out 50 drawbar horsepower. Weighing 25,000 lbs., it was powered by a Rumely-built, two-cylinder engine. The horizontally-opposed cylinders had a 10x12 in. bore-and-stroke operating at 375 rpm. Accessories included the famous Secor-Higgins carburetor.
