The All-Crop concave set includes 12 concaves and comes with 2 additional inserts. The setup produces the most optimal results for crop threshing and separating amongst a range of crops without having to change concaves. The set can, however, be customized for specific crops or conditions by changing out the individual inserts or concaves (see SBJX0747-2, SBJX0747-3). Inserts are replaceable and reversible 180 degrees for economical refurbishment.
