Got in the field with just delivered 9770 yesterday and brother said that he can still pull it down just like our 9760 in hailed on 130 bu. corn w/12 row head running 4.5-4.7. Was hoping that JD finally had the problem with combine power fixed, but guess not.

Dad complains about it daily. Specially when we were in beans.

We do too, but only when going uphill, unloading on the go with a 12 row chopping head. I didn't hear any complaints when they were in the beans. At times, it'd have been nice to have a 98, but slowing a little ain't gonna ruin the year. Did your 9760 have the 9L too or the 8.1?

It has the 9L, we still have it, and it is still having power problems. I just don't understand why JD can't get the power problems figured out. The JD tech's "think" they have the problem figured out on the 9760, but want to come out and ride the machine in action with their computer hooked up, we did the same thing last year on another 9760, cost 1500 for them to ride it all day, they put in a dtach case and dtach said, in essence, that the owners were expecting to much from the machine. On this one, they think that the pump on top of the injector pump is the problem. If we get lucky and get in a full day after this last snow melts, we might find out.

I take it you've checked the obvious air and fuel filters? The electronics on these things are amazing, but it sucks when you need a tech to do any major work. Hope you get it figured out.

I thought the deere was considered a powerhouse, for the most part. That most chips were bought for other combines. I am more a red guy when it comes to combines, but this topic surprised me. So....... is there a "problem", or are you expecting too much??? I am not sure what is worse! I wish our 2388 had the power the newer one had, and especially what the 2588 has, but that is a mechanical inj. tweak. Goodluck

The emission Gods is your problem. Every color combine owner in the rice area is complaining about tier III combines. We have 2, 8010 AFX CASE IH’s and the tier II has great power. The tier III has an Agricultural Diesel Solutions power chip and it won’t even come close to the tier II stock engine.

DON NMO has some pretty strong opinions in this matter discussed in this thread. It is a must read: http://talk.newagtalk.com/forums/thread-view.asp?tid=118889&posts=2...

Mine seemed to be alittle short on power all of a sudden. It was the air actuator for the turbo,emissions. Deere put a new one on. It really goes now.

The 9760 we've had since new has always had good power, other than the time when the tubo vane actuator went bad. Then it would hardly carry itself down the road. This has the tier III 9.0L motor. It has always seemed that when we were combining we could speed up a couple tenths of a mph when we kicked the unload auger on. I've heard of other machines that would fall on their face when you kicked the auger on.

Currently we're picking 200 bpa (wet) 24% corn with a 612 and tracks running 4.5-5mph. Last year in similar but dryer corn we ran 5-5.5 with an 18 row 20" head. The aftermarket tracks eat up a lot of HP.
