Default 9770 vs S670

Looking at trading our 9770 off and get into a S670. Wanted to know if anyone who has made this jump was happy and did deere add more cleaning capacity to the S670 vs 9770. Also going to get a price on a 680 just to see. We have talked to guys that went from 9870 to 680 were impressed but havent heard to much about the 670. wondering if its time to move to the 680. we already run a 936D. if we went 680 we would go to a 40' johndeere flex draper.

We are happy with our 670's, ran them with 9770's this year and will have all 670's with 35' MacDon FD75's for next year. Both machines are similar, we could tell the 670's had more power along with the added bells and whistles. As far as cleaning capacity goes not really noticeable. In certain crops the 9770's did a nicer job. As far as breakdowns, nothing major for their first year out.

My 9870 was equal to the S680. Expect no capacity increase. There is only a new series because they had to change the motors. More bling in the new series, but nothing but unhappy buyers around here.

Have you considered a 770 0r 780 Lexion? If I didn't travel all over the country, that would be my choice!

While true I don't think jaws is looking for that big nor that expensive a unit.
We will not be able to buy a 780 in NA.
Sorta.
Kinda.
Maybe?

One point to keep in mind... If you get an S670 with the PBST (3 speed) transmission, you must have a display in it if you want to move it. Also not looking forward to the day an S670 needs a fan belt.

We moved from 9770 to S670 this past year. Basically the same machine. Cab of course is different with some improvements however the interior noise level is a disappointment. 9770 would be quieter.

The HP in a S670 is inbetween a 9770 and 9870, the overall machine is basically the same as the 9870. Difference is basically only cosmetic and few extra options. The S680 is bigger than the 9870, we figured in the 15-25% range in 50 bu canola. The cleaning capacity is larger and is improved, going 20% faster in 50 bu canola and throwing out less than our 9870. S680 has more options than the S670, larger hopper than folds, rethresher versus returns back into the rotor, etc. If you are looking for a bit more capacity but basically same machine get a S670, if you want step up then move into a S680...only my opinion though.

I'm going to bet that's swagged and not side by sided.

Both running in the same field, demoed the S680...not right side by side but within a couple of swaths of each other throughout the field. S680 could go faster but we don't like going faster than 5 mph picking up a canola swath...too much shatter loss in our opinion. I was impressed with the machine. Ran the rotor at 750, concave was almost wide open, the fan was in the 900-1000 range, shoe was around 10-12 and sieve was in the 2-4 range, slight returns through rethresher.
