Been through the John Deere gamut the past 20 years. Currently running 9870, couple 9770, 9660 and still have 9610 banging around... We harvest larges acreage of oats, barley, flax, canola and soybeans with a short harvest window of Sept till Nov 15.

To put it short im at my witts end fixing STS combines. This fall we have went through the usual excessive amounts of excellerator and discharge beater belts. Two fans through radiators, a complete shaker pan meltodown, two cleaning fan explosions and two AC compressors. We dont have near enough hours on these machines to say they are worn but they are acting like junk with a couple thousand seperator hours. Not to mention down time on muggy evenings when dew sets in early.....

The old 9610 on the other hand just keeps plugging away up and down the field. Tough as nails

So im really interested in going back to conventional machine and pretty much narrowed it down to 670's.... I have a John Deere dealer locally but dont like some options Deere is lacking for T670. Claas dealer 5-1/2 hours away but have the options I want....

Let me know your track record for both Deere and Claas 670 machines

Which combines lost the fans? Seen my post about 9870 fan at 1400hrs?
Any warranty/insurance/dealer help? Did you or dealer check fan play at all?
I am very disappointed with the reliability.

On the 670 did you see thread below?

9870 puked fans 2800 engine hours then again 44 hours later... Pure crap! My dealer is working for me

Yeah, 5.5 hrs is too far for something as critical as a combine. It's like marriage you have to learn to love what you've been given. I would switch to the T series though given your conditions.

Alot seem to complain about T670 throwing lots of grain over...some guys in the UK have them and have the same issue, and the NH equivalent and claas is much better capacity wise...when you look at the designs there all similar and can't work out why the deere is throwing grain, is it sieve or walker loss no one has ever said?.

I'd go ride in both because if that claas 670 is as good as they say it's going to alot more profitable and have alot less hours on it per year if it's travelling 30-40% quicker than the deere...I'm a deere walker fan so would love to have a play with a T670.

Don't quote me but I think deere is working with a few owners in Uk to see why the grain loss is occurring and they can't keep up with similar machines..

Also fuel use in claas might be less?...

Hard to beat 9000 series for reliability if you look after them..!..

I do have a great New Holland dealer locally.... The unfortunate thing is there are ZERO New Holland combines in this area. I actually have never stood beside a New Holland machine...

I would just love to get a CX8.8, a Deere T670 and a Claas 670 in the same field and let'm have for the day.

We run a Claas 670 and love it this is our 4th harvest with it. Our dealers here Sask can make a parts box with all the belts, filters, sensors and anything else you may need. Not sure if your dealer does that or not but maybe ask seeing as your five hours away. Claas combines seem very well built in 14 years we have never had a major breakdown on the 4 combines we've had. We do keep belts and a few other things on hand if we do break something.

Push hard to make this happen. Put the offer out to all 3 and make a field day out of it. If you have that many combines, the dealers should be willing to bring some machines out with guys to set them up. If it does happen, report back on your findings. I'm hoping the cx wins:6::6:

But there's probably zero Claass as well.
If you can get one of those parts boxes and you are pretty handy/don't mind working on it yourself maybe the Claas wouldn't be a bad try.

No question it's a vastly better machine than the other 670, lots of evidence to that effect on this forum lately.

Go whole hog and have the Gleaner people bring out an S88 too! Or MF 95x0 or whatever. Not a Agco user myself, but hearing more and more people saying the S series do a beautiful job and are very fuel efficent.

Of course the REAL problem is you traded off that 7720...;)

I'd say the Claas--hands down winner, but like many....5.5 hours??? OUCH.

From what i can pick up in the UK the CX8.8 is beating Deere hands down..and Deere guys are going to them begrudgingly or keeping there CTS's.

What perplexes me is if you look at the cut away for the NH JD and Claas ...there pretty darn similar so not sure where the Deere is falling down? Do the walkers run to quick or slow...The NH cylinder is larger diameter but machine is narrower...all three would be a good field day!

I wouldn't mind a drive of this girl...

If you don't bale why do you want a walker style? Im asking from point of view of a guy who doesn't bale and grows wheat soybeans and canola as main crops.

We are in an area of extreme humidity.... Dew sets in early in the evening and leaves late in the morning. Just seems the STS rotor has a heck of a time getting any productivity through those hours and the fuel use in our conditions is 30-40% higher per acre than our old conventionals. Drive around my area at 8 pm and you can point out the rotary machines from 3 miles away... Just creeping along trying to hold grain in and not plug damned excellerator beaters

The only place I can really say the rotary machines pay back in this area is in dry oats and barley. In tough wheat, flax and canola theres no benefit from my perspective. Soybeans are a toss up... Of course this is just comparing to our old 9610.... I'm certain these new hybrids are far more productive than it

Claas 670 or Deerd T670

Deere probably won't show!

That makes sense I guess. We get damp here to as august turns into september and the sts usually is barking like a dog right at sunset and we just park it as losses go up and productivity way down.

Ive always wondered if we should trudge on at 2mph or quit. We quit 99% of the time. Not sure if that makes us quitter but gosh doing 8 acres per hour cant be to economical with a class 8 machine.

Well, not really new and there is only one.

I hear you on your conditions.

ALL combines max throughput is reduced by "tough" and "damp" conditions.
Walker machines less than rotaries, but the downside is while the walker units can put it through the walker separation system struggles.
Claas hybrid system slows more % than walker (from a much higher speed) slows less % than a rotary but still separates better than both.
Due to the separation (pardon the expression) of the function of threshing and separation and the inherent adjustability of that hybrid system.

I'll echo Don's post, we went to the hybrid lexions at the same time we had the JD 9600's around and we'd put them to bed before the lexion's every time. When it got that tough the Lexion's were still getting the grain, the walker's were just putting it on the ground.

We run in lots of tough conditions and wouldn't even consider a walker machine.

We just switched from a CR to a CX and am kinda missing the rotary. Don't get me wrong, they both do a good job in their own way, but find the walker machine starts putting grain over them if you try pushing it a little, the rotary never seemed to increase loses when it was worked harder. The conventional is alot better on fuel but the rotary did a better job of thrashing. We never found the rotary too bad when it got tough, it did slow it down but wasn't terrible, and we have taken off alot of tough and damp grain. I wouldn't be afraid to go with a rotary because people say they suck when it's tough, they aren't that bad.

We run a 760 lexion and a 9600 John deere, the other day we were doing tough green canola straw and during the day the lexion was doing around 5mph and the deere was doing 2.2, at night the lex was doing 4.5 and the 9600 was at 1.3, the lexion really doesn't know it's tough out compared to any other combine I've ever been around, in really wet green 60bu wheat straw it'll do 18 acres per hour all day putting all the straw thru, our sts would have sounded like Berlin in 1945 with about as much carniage in those conditions, with way less grain loss.
