UPDATED INFO
Several people have commented on the 12-foot-long metal object in front of the Centennial Building at the Polk County Historical Society Museum in Crookston.   

John Reitmeier: Crankshaft for a big three-cylinder engine.
John Bruender: Probably from a wind generator.
Tim Ryan: 90% sure it’s a stream engine crankshaft.
John Gilles: A crankshaft for a locomotive.
Captain Crunch (his screen name): Camshaft crank “two spots for pistons or stamps for ore to be crushed.”

Historical Society President Jerry Wentzel said two locomotive crankshafts were dug up when the Crookston pool was built. A railroad station was previously located in the same area.
