Kuhn introduces the new 5640 field cultivator. The 5640 model brings several new features and sizes. New 56’ and 60’ sizes are available for producers looking to utilize the ever-increasing hp of large tractors. The machine has been designed for narrow transport. In addition, the frame has been designed to optimize both strength and weight per foot insuring machine performance in wet conditions. Hydraulic positive stop depth control is a standard feature that allows the operator to adjust the depth of each section independent of the other sections.
