It features a choice between a 301 cubic inch, inline six-cylinder, liquid-cooled, naturally aspirated diesel engine with a compression ratio of 16.25 to 1, and a 265 cubic inch, inline six-cylinder, naturally aspirated gasoline engine. The diesel engine produces a maximum power of 64.01 HP at 2000 RPM, with a fuel consumption of 4.199 Gal/hr and a fuel efficiency of 0.458 lb/hp.hr (15.24 Hp.hr/gal) at maximum power. The tractor is equipped with a selective gear fixed ratio transmission plus operator-controlled partial range power shifting, offering 8 forward and 2 reverse gears with advertised speeds ranging from 2.3 mph to 14.5 mph. The brakes are contracting band and disc operated by two foot pedals. The tractor has a three-point hitch (Category II) at the rear, with a drawbar height of 19.5 inches with ballast and 21 inches without ballast. The hydraulic system is an open center, constant running type. With ballast, the operating weight is 10300 lb, with 2210 lb on the front and 8090 lb on the rear. The tractor is fitted with 7.50-16 front tires and 18.4-28 rear tires, both with liquid ballast.
