The All-Crop concave set includes 6 concaves that are half the size as compared to OEM, bolt-on front slope, 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 SBJ0747-2, SBJ0747-3). Inserts are replaceable and reversible 180 degrees for economical refurbishment.
