The quality of threshing that this machinery offers is inimitable. It allows restricted flow. And as a result, grain on grain threshing takes place. This grain-on-grain threshing causes the quality of the threshing process to get enhanced and amplified to the optimal level. The Case IH Xpr2 Concave has a round bar. This feature enables it to have a larger surface area for threshing. The approximate percentage of the threshing area that it can undertake is about 135% more.
