Rotor Transition Cone
- Simple geometry gently transitions crop from feeder to rotor with no moving parts
- Crop smoothly accelerates in a spiral motion
- From feeder speed to threshing speed – 5 mph (8 kph) to about 60 mph (97 kph)
- Without congestion, while promoting grain quality
- Ensures maximum combine capacity and performance
- While drawing crop into the combine transition cone, the rotor impeller system draws 1,100+ cu. ft. of air per minute ensuring a clear view of the header
Rotor Cage
- Single in-line Axial-Flow rotor coupled with a concentric rotor cage
- Delivers gentle, multiple pass, grain-on-grain threshing
- The hallmark of an Axial-Flow machine for over 30 years
- Exclusive adjustable rotor cage vanes
- Allow you to customize crop flow to conditions for maximum performance and productivity
- Vanes have three positions: fast, mid and slow
- Crop control provides uniform crop flow and more consistent power needs while reducing peak horsepower and consuming less fuel
Rotor Concave/Module Wrap
- One of the most important elements affecting combine capacity
- Instead of longer rotors, Case IH Axial-Flow combines use concave/module wrap to increase capacity
- 5088, 6088 and 7088 combines include a one-piece 156 degree concave wrap
- 7120, 8120 and 9120 combines include a two-piece 180 degree module
- Concave/module wrap provides a longer, more efficient threshing/separating zone for optimum threshing and separating capacity
- Electrically operated concave/module adjustment is monitored by the in-cab position display
