Subject: Difference between 2388 and 2577


Curious what the differences would be between 2388 and 2577? Also anyone using a 6 row head on a CIH combine with duals?

Farm in WC Iowa
189 where I learned math :)
Not here
We run 8/22" and need singles and the ladder turned in to not run over the inside row.

Now not being a smart ass. I would say less than 10% less in capacity and hp

In 2006
2377: 255 H.P. 8.3 Liter engine, 190 Bu. grain tank
• 2388: 285 H.P. 8.3 Liter engine, 210 Bu. grain tank
• AFX8010: 400 H.P. 10.3L engine, 330 Bu. grain tank


In Model Year 2007, the Axial-Flow 2577, 2588 and 7010 combines were introduced.

• Axial-Flow 2577: 265 H.P. 8.3 Liter 230 Bu. grain tank
• Axial-Flow 2588: 305 H.P. 8.3 Liter 290 Bu. grain tank
• Axial-Flow 7010: 350 H.P. 9.0 Liter 315 Bu. grain tank
• Axial-Flow 8010: 400 H.P. 10.3 Liter 350 Bu. grain tank

2577/2588 Product Enhancements
• Yield moisture and flow sensors and AFS badges became standard equipment.
• The AFS Pro 600 became used as the yield monitor display.
• Field Tracker: Additional bolts were added on each side of the feeder to prevent the feeder face plate from tipping forward under heavy load.
• The feeder top shaft sprocket assembly has been lengthened to reduce shaft bending.
• The third cylinder anchor bracket on the front axle became standard equipment.
• Final drive gears were shot peened to improve gear life and increase durability and strength.
• Wheel bolts went from M20 to M22 to provide better wheel retention. A common dual wheel was used for 7010 and 8010.
• The rotor drive coupler attaching plate thickness increased in the rotor bulk head in order to achieve longer bolt thread engagement.
• The rotor gear case shift lever was plated and the bore size increased to eliminate seizing due to corrosion.
• Rear axle: Material thickness was increased on the center section (from 9 mm to 12.7 mm).
• The unload rate was increased to 2.4 bushels.
• The unloading tube length was increased to 18' or 21'.
• Reside Management: The straw spreader curtain length was increased.
• The material thickness of the bottom tailings elevator housing was increased.
• The clean grain elevator slip clutch torque was increased by 20%.
• The Power-Clean Evacuation System was introduced and included a hydraulically driven evacuation fan and an optional rotary brush.

Central Illinois
IIRC, the 25XX series were the fist Case-IH combines to offer bin extensions as standard equipment.
