The Minneapolis 39-57 is a utility tractor with a standard tread design. It has a 2-wheel drive system and manual steering. This tractor is powered by a Stearns gasoline engine with 4 cylinders. The engine is liquid-cooled and naturally aspirated, which means it doesn't use extra parts to push air into the engine. With a very high engine displacement of 617.7 ci, this tractor packs a lot of power for its size.
The 39-57 has a gear transmission with 3 forward gears and 1 reverse gear. It rides on steel wheels, both in the front and back. The tractor is quite heavy, weighing 9,695 lb, which is above average for tractors of its time. It uses a hand crank to start, which was common for older tractors. In tests, it showed impressive power, reaching 57.39 HP at 999 RPM. The tractor can pull 3,723 lbs while moving at 4.01 mph, which shows it's good for tough farm work.
