Suggest placement of helical kickers for sunflower
on the 30" Specialty Rotor on the 1680, 1688,
2188, and 2388 combines.
Suggested placement of helical kickers for sunflower
on the 24" Specialty Rotor on the 1640, 1644,
1660, 1666, 2144, 2166, 2344, and 2366
combines.

Increase Productivity with the Case IH
AFX Rotor
With over 25 years of experience in rotary technology, Case IH
stands tall with the most advanced design in rotary technology
on the market today. The AFX rotor is now available as a
Service retrofit for all 40, 60 and 80 size Axial-Flow combines.
Benefits of the AFX rotor include:
• Increases throughput by as much as 25% in tough crops or
harvesting conditions
• Allows harvesting earlier in the day, and later at night. Adds
hours to the day when tough conditions stop most combines.
• A smoother, uninterrupted crop flow means more consistent
delivery to the cleaning system
• Reduces peak horsepower demands in tough conditions,
reducing load on the rotor drive belt
• Creates a powerful vacuum to move dust away from the
feeder house and cab for better visibility to the header
• Results in quieter operation
• Improves fuel efficiency
The position of the standard eight straight separator bars are
for a corn combine equipped with the AFX rotor
(see figure
23.1).
The position of the four straight separator bars in a combine
equipped for use in small grains with the AFX rotor
(see figure
23.2).
A unique feature about straight separator bars is removal isn’t
required to harvest other crops – a great time saver. These
separation bars control material flow for effective separation.
However, they are not recommended for rice.
• Use six bars on 2144 and 2166, and eight bars for the
1680, 1688, 2188, and 2388 to harvest corn
• On grain machines, the separator bars are installed from
the factory. The 1640, 1644, 1660, 1666, 2144, 2344,
and 2366 have three bars in-a-row over the first grate and
the 1680, 1688, 2188, and 2388 have four bars mounted
in a staggered pattern over the first and second grates.
Refer to the Operator’s Manual for correct placement of helical
kickers
(see figures 23.3 and 23.4).
