Case IH AFX rotor most advanced design in combine technology

In response to the expanded capacity and productivity needs of combine operators, Case IH announces a breakthrough in rotary combine technology — the AFX rotor.

“The Case IH AFX rotor is the most advanced design in rotor technology on the market today,” says Leo Bose, marketing and training manager for Case IH harvesting equipment. “Our new rotor increases throughput in a Case IH 2388 Axial-Flow combine by up to 25 percent, while improving fuel efficiency and reducing wear.”

AFX rotor technology is the first piece in a new generation of single rotor combine development from Case IH. It continues to deliver the superior grain quality, grain savings, crop adaptability and simplicity that have distinguished the Axial-Flow line for more than 25 years.

“The Case IH AFX rotor takes harvesting technology to a new level,” says Bose. “It will improve capacity throughout between 5 and 25 percent over the previous specialty rotor design, particularly in tough harvesting conditions.”

Graduated pitch inlet flights transition crop from the feeder to the rotor cage. This design creates smoother, more consistent flow of material from the feeder to the threshing and separating areas.

The rasp bar configuration also has been redesigned to provide more “grain on grain” threshing, a hallmark of all Axial-Flow combines. The result is reduced wear and tear on threshing components, improved throughput, quieter operation and reduced horsepower requirements in tough harvesting conditions.

“The Case IH AFX rotor can also be retrofitted into late model 1688, 2188 and 2388 Axial-Flow combines,” he notes. “The unique ability to upgrade Case IH equipment speaks to our commitment to the needs of our customers and the simplicity and superiority of the Axial-Flow rotary system.

An upgraded rotor drive helps maintain constant rotor speed, despite varying crop conditions. The new drive has larger rotor drive pulleys, along with a spliceless rotor drive belt to improve the belt's reliability and service life.

“More and more farmers are opting to collect on-the-go yield data during harvest, and they're also correlating that information with differential Global Positioning System (GPS) data to map their fields,” says Bose. “Using the updated Case IH Advanced Farming System (AFS) Universal Display Plus, combine operators can now see moisture and yield maps develop as they travel through their fields.”

The updated AFS Universal Display Plus provides three fully configurable user screens, as well as configurable markers. The upgrades allow for real-time, on-the-go yield and moisture mapping. In addition, the new Case IH AFS100 WAAS receiver provides free satellite-based differential correction.

A new AFS software package also provides improved report and analysis capabilities, as well as the ability to import and export most major industry file formats.

“The 2003 model Axial-Flow combines also take advantage of a feature introduced to the industry last year on Case IH CPX610 six-row cotton pickers,” Bose adds. “A hydraulically driven rotary air screen reduces cooling system service intervals by screening out more chaff and debris and maximizing airflow to the cooling system.”

The Case IH-patented rotary air screen features replaceable wire cloth mesh panels, instead of the previous punched hole configuration. The new design results in improved airflow to the cooling system. In addition, the radial seal for the screen is now made of a composite rubber that is more effective in preventing trash ingestion around the screen.

To further increase cooling efficiency, the rotary air screen, coolers, radiator and fan are placed directly in front of the engine. This allows for a straight-through airflow.

The new direct-flow cooling package makes servicing coolers and radiators easier. In addition, a new de-aeration tank provides complete fluid contact for the engine's cylinder sleeves, thus reducing the cavitation caused by the air.

When service is needed, a new access door further simplifies the process. The door is constructed from a soybean-based plastic material and is extremely durable. A chaff discharge chute, the rotary air screen brushes, straw spreader drives, chopper drives, and rotor gear case are all easily accessible.

Other key features found in 2003 Axial-Flow models include:

  • Ten additional horsepower on 2366 combines with a new Case IH air-to-air, after-cooled engine for improved performance.

  • New operator seat with adjustable left-hand armrest, along with redesigned seat and back cushions.

  • New mufflers for quieter machine performance.

  • New air cleaners for improved engine performance and simplified service.

  • Heavy-duty non-powered guide axles with dual cylinders offer increased heft for 12-row applications and hillside combines.

  • A new cover for the thrust bearing on the Cross Flow fan improves bearing life by preventing material from entering the thrust bearing.

Among the improvements for Case IH 2003 model year 2366 and 2388 Axial-Flow combines is a hydraulically driven rotary air screen. The patented rotary air screen was first introduced on Case IH CPX 610 cotton pickers last year. It screens out more chaff and debris to maximize airflow to the cooling system.
