Although certainly not the largest tractor on display, the new Arion 660 tractor was a standout attraction for many contractors and larger farmers who attended the recent roadshows. The Arion 660 was first showcased at Agritechnica last November with a number of units sold in Ireland this year. The Arion 660 was introduced by Claas in an attempt to bridge the gap between the 600 series and the 800 series tractor ranges. The 660 model offers users more horsepower in a smaller frame.
