Case IH HDX 2 Series sicklebar headers use the counter-stroking action of dual sickles to shear crop cleanly while the unique floating auger keeps the crop moving smoothly to the conditioning rolls. Four models are available in cutting widths from 12 ft. 3 in. to 18 ft. 2 in. (3.73 to 5.56 m). The headers are compatible with all Case IH WD 3 Series windrowers.
