Problem Solver For Case-IH Rotaries

Problem Solver For Case-IH Rotaries COMBINES Accessories 18-2-25 Problem: The "Specialty Rotor" introduced in 1986 by Case-IH for its Axial Flow rotary combines solves the material handling limitations of the standard rotor but it gets low marks on threshing ability, particularly in tough-to-thresh wheat and corn. Here's why: The Specialty Rotor has a series of small rasp bars mounted on pedestals spaced several inches apart and lined up in a helical pattern on the roller drum's surface, allowing too much crop material to pass within the spaces between the rasp bars instead of getting pressed against the concave. In easy threshing conditions, the flow of material is sufficient to thresh the crop. However, in high-yielding crops, and tough-to-thresh wheat and corn, threshing efficiency leaves a lot to be desired. Solution: Equip the Specialty Rotor with long-wearing chrome alloy Rotor Bars from Gorden Harvesting and Equipment, Wichita, Kan. "Combined with the Specialty Rotor, they give you the best of both worlds ù great material handling capacity and top-notch threshing efficiency in virtually all crops and conditions," explains Marvin Gorden, inventor-manufacturer of replacement Rotor Bars. They improve threshing action by wedging crop material between each Rotor Bar and concave to thoroughly thresh out each head of wheat or ear of corn." Each bolt-on Rotor Bar replaces two original rasp bars in the threshing area of the Specialty Rotor. To maintain balance, they are installed in pairs on the 1680, and in triplet on the 1640, 1660 and 1670. The threshing action increases as more Gorden Rotor Bars are added. As many as 20 can be installed on the 1680, and up to 15 on the 1640, 1660 and 1670. "In most instances, as few as 12 Rotor Bars on the 1680, or 9 on the 1640, 1660 and 1670, will get the threshing job done the first time through. With Rotor Bars installed, the lower sieve can be opened Crider - 3/8 in. or more - and still maintain a good, clean bin sample," says Gorden. Individual chrome alloy Rotor Bars sell for $61. Sets of nine sell for $555 and sets of 12 for $735. Gorden also sells chrome alloy replacement impeller wear blades. A three-piece set sells for $231, and a four-piece set for $270.
