Refer back to my original post when you mentioned this demo was going to occur. I told you this would happen. JD is notorious for having special demo units that have seeemingly unlimited horsepower. What you were actually driving was a 9860 made out of a 9660. Trust me, if you buy an unadultered 9660, you won't cut anywhere close to 6 mph with a 30' head in beans above 45 bu_acre. As they say, that dog just won't hunt. In extremely poor beans, maybe I could see it, but then an R72 ought to cut that fast in 30 bushel_acre beans. No class 6 combine, or even class 7 that is stock will do what you saw that 9660 do with a 30' head in good beans. I have several friends who have tried JD demo units, only to be sadly disappointed when their machine shows up and doesn't measure up to their demo. Don't let them pull the wool over your eyes. I would trust very few JD dealers farther than I could throw them. Here's a better test: find a neighbor who is running a true 9660 or 9760 STS and put it up against a new R65 or R75 with the CDF rotor; then you'll see that the Gleaner is still not behind; it's just the green boys up to their old dirty tricks again. They just can't play fair, so they cheat, yes I said cheat! Don't be fooled! As for the head, the AGCO head is still built better than a Deere anyday. Yes, the JD head feeds nice. But it sure doesn't float like the Gleaner, and they've been having to weld on new heads like crazy up here because they are just cheap. The full finger auger is coming, so I've been told, so the AGCO boys are listening. The Gleaner is still the better combine, so don't fall for JD's parlor tricks. Man I hate it when they do this. Gets my blood boiling.
