Cross-Flow Cleaning Fan
- Patented Case IH Cross-Flow® cleaning fan delivers extremely uniform air flow
- Creates a vortex at its center, resulting in uniform air flow across the entire sieve
- Ensures a clean sample at high harvest speeds
- Maximizes grain savings
- Redesigned fan air inlet shields maintain cleaning fan performance in adverse conditions
20 Series self-leveling cleaning system
20 Series Self-Leveling Cleaning System
- Allows entire system (top sieve, bottom sieve and fan) to level itself for optimum cleaning efficiency on hills, flat fields and on end-row turns (it banks on end-row turns)
- Axial-Flow 7120 levels up to a 14% slope
- Axial-Flow 8120 levels up to a 12% slope
- Axial-Flow 9120 levels up to a 12% slope
- Cleaning system incorporates:
- Larger-diameter Cross-Flow® plus cleaning fan
- Active grain pan – levels the crop mat and stratifies grain from chaff before it reaches the sieves
- Enhanced shake geometry – moves the mat while lifting it higher off the sieves, improving air flow for better capacity and cleaning efficiency, even with high-moisture crops
- Advanced system saves grain and increases productivity
- Saves between $4 and $10 per acre, depending on degree of slope
- Ensures a more uniform mat entering the sieves for improved cleaning efficiency
88 Series Augers & Sieves
- Auger bed of five augers delivers crop smoothly to the grain pan and cleaning area
- Chaffer sieve has three adjustable sections
- Allows easy fine-tuning for different harvest conditions
- Eight different sieve combinations let you clean most any crop
- Front, middle and rear sections adjust independently for better performance
- Lower and upper sieve sections move in opposite directions for better cleaning
- Several sieve choices are available for maximum cleaning and grain savings
- Convenient sieve access door and light allow easy inspection
- External right-hand sieve adjustment levers are provided for added convenience
- Optional hillside dividers are available for the top sieve and grain pan to improve operating performance in hilly terrain

Automatic Crop Settings
- On 88 Series combines the automatic crop settings (ACS) option:
- Uses the electrically adjusted upper and lower sieves, plus rotor speed, concave position and fan speed to quickly set the combine for each crop harvested
- On 20 Series Axial-Flow machines, the ACS:
- Provides presets for up to 10 different machine settings and 80 factory crop presets
- Enables each crop type to contain multiple user-defined work conditions
- Can be transferred from machine to machine for fleet operators
20 Series Tri-Sweep Tailings Processor
- Tri-Sweep™ Tailings Processor uses three sets of impellers to gently re-thresh and elevate the tailings, returning them back to the active grain pan for final cleaning
- This results in:
- Higher machine capacity
- Increased harvest efficiency
- Improved grain quality
- 5088, 6088 and 7088 combines are equipped with a tailings elevator
- 6 x 8 in. (15 x 20 cm) top driven roller chain with rubber flights
