Names like Allis-Chalmers, Oliver, Case and more will draw plenty of attention over the next month, beginning with Saturday's Liberty Grove Historical Society Antique Tractor and Arts Festival. Dozens of tractors and other antique farm equipment will bring an extra dose of history to the organization's grounds atop the hill in Ellison Bay. The festival is part of a busy stretch for antique tractor enthusiasts. It serves as a precursor to the Northeastern Wisconsin Antique Power Association's Valmy Thresheree in mid-August. This year's event will highlight Oliver, Minneapolis-Moline and White tractors, along with traditional tractor pulls, farming demonstrations and other activities.
