Case IH launched the first single-rotor Axial-Flow^® combine in 1977. Thanks to the simple and reliable design, more than 30 years later, single-rotor technology still leads the industry.

Six core principles drive AFX Axial-Flow rotor design:

• Simplicity – Fewer moving parts for better reliability and easy service
• Grain Quality – Gentle grain-on-grain threshing minimizes grain damage
• Grain Savings – Through thorough threshing and efficient separation
• Crop Adaptability – Harvests more than 80 types of grains in many conditions
• Matched Capacity – Matched systems optimize crop flow and productivity
• Resale Value – Impressive resale value maximizes your investment

AFX Rotor Design

• Standard 30-in. (76-cm) diameter in-line rotor offers gentle, multiple-pass grain-on-grain threshing:
  • Single concentric moving part for threshing and separating requires fewer adjustments and less maintenance than conventional machines
  • Efficiently moves material through the rotor cage – regardless of crop or conditions – to maintain crop flow and crop control
• Multiple-pass threshing and 360 degree centrifugal-force separation results in:
  • More complete, gentle threshing
  • Increased grain separation
  • Less damage to fragile kernels
• Smooth uninterrupted crop flow:
  • Reduces horsepower demands
  • Decreases fuel use
  • Reduces wear on threshing components

Optional Small Tube Rotor

• Small Tube (ST) rotor is standard for rice and optional for small grains producers
• Provides increased productivity in tough harvest conditions
• Smaller diameter and taller rasp bars let more tough rice straw work its way through the entire length of the rotor
  • Crop feeds more evenly
  • More crop-on-crop threshing opportunity
• Recent improvements enable:
  • Higher grain quality in tough threshing conditions
  • Higher ground speeds that boost productivity
  • Easier operation, with smoother material flow
  • Less rumbling, so reduced likelihood of slugging the rotor
  • Available on 20 Series and 7088

Controlling crop flow is key to harvesting success, and it starts with delivery of the crop from the header to the rotor. Axial-Flow^® combine feeders promote a thick crop mat and are sized to match combine capacity – both threshing/separating capacity and throughput requirements of each combine model. Axial-Flow matched capacity:

• Ensures smooth, consistent crop flow into the machine and improves productivity
• Provides maximum capacity and grain recovery

Feeder/Header Interface

• All Axial-Flow combines have a common feeder/header interface
  • Incorporates single-point header latching, a hydraulic multi-coupler and an electrical connection
  • Makes header attachment faster, easier and safer
• Optional Terrain Tracker provides optional header lateral tilt
  • Allows header to follow ground contours as it pivots to increase your harvest efficiency
  • Provides 5 degrees of tilt each way, for 10 degrees of movement
  • Available on all Axial-Flow models

Feeder Chains

• All models equipped with serrated 1/4-in. (1/3-cm) feeder slats for consistent feeding
  • Serrations are rolled into the slat to reduce the chance of grain damage

• Spring-loaded feeder chain tensioning system with a quick visual gauge
  • Standard on all Axial-Flow combines
  • Provides consistent chain tension
  • Provides a quick visual indication of chain tension
  • Reduces noise
  • Virtually eliminates routine adjustment
  • Increases chain life
  • Three-strand feeder chain on 88 Series combine
  • Four-strand feeder chain and three-slat conveyer design on 20 Series machines
    • Increases feeder chain reliability and durability

Auto Feeder Speed

• Industry exclusive patented auto header/feeder to ground speed control
  • For corn harvest, header and feeder speed automatically adjust to match the combine’s ground speed
  • For more grain in the bin and less on the ground for operations in corn
  • Available on 20 Series

Optional Heavy Feeder Lift Package

• Optional for larger, heavier heads – such as 16-row corn heads or chopping corn heads
  • Two 3 1/2-in. (90-mm) lift cylinders
  • A higher-capacity tilt cylinder
  • Additional feeder reinforcements
• Available on 8120 and 9120 models

The patented transition cone with impeller system on the front of the Axial-Flow^® AFX rotor smoothly accelerates the crop mat, promoting positive material flow with less impact damage – and superior threshing and separating performance.

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

20 Series Rotor Modules

• A variety of different rotor modules let you adapt to a variety of crops and harvesting conditions
