Well, I may only be 16 years old, but i spend a lot of time researching machines online. I have come to the conclusion that ever since Case IH has come out with the rotary combines, they have been ahead of the crowd. When they first came out with them, the only major competition was John Deere's 8820 Titan 2. Today, their competition is still the same, but times have changed. Now John Deere has a rotary combine that has made Case IH's job a little bit tougher. Even though their 2388 series combine is 2 classes below John Deere's newest big boy, its not much behind in the field. Of course, it wont be able to pick quite as fast, it can still clean corn better, not grind it, and practically eliminate grain loss. John Deere may be ahead in the speed and capacity categories in this situation. BUT.... Case IH has a new, completely redisigned combine called AFX 8010. With a 10.3 liter, 375 hp French engine, it's got more power than the Deere and is even SMAllER that the Deere engine. Inside the combine is practically all new. With a new "AFX" rotor, new cleaning system that's over 10,000 square inches (10,075),and a 330 bu. grain tank. it's bigger that the 9860 machine, cleans more grain, more efficiantly, and stores it all up top. So, going back to the question "2388 vs. Deere" im gonna say Deere's new machine. But if you want to know "AFX 8010 vs. Deere" im going to say, without a doubt, the Case IH combine takes the throne for King of the Combines. It's got exactly what it takes to be the best and with some minor changes down the road, will remain the biggest and the best combine to tear through the worlds biggest corn fields. feel free to email me with your replies or questions. -BUD
