Default New S690 - First report

Here are pictures of the first report of the Profi Magazine...











Ok, I try to translate it...

S690
- John Deere is keeping the name for their most powerful combine. But the technology significally changed and it was new constructed. Two interesting numbers elucidate this: Towards the previous model 45% of the parts were renewed and the budged for the development exceeded 100 million euros.

Already from the outward the new S class comes up with a modern and fresh design. We have shown the first pictures in 09/2009 and 2/2011. In total the S-line contains 4 models for the season 2012...

The 660 will be offered with the known rotor and a reduced equipment package. The new parts will be offered in the 670, 680 and 690, mostly already in the basic version.
While unloading the S660 and 670 receive additional 25 kW/34hp maximum power. The 680 and 690 will come up with 37kw/50hp additional power. According to JD, The new "isocrone" engine adjustment keeps the rpms of the threshing organs constant, even in partial load.

For heaver headers, the new S series got a new feederhouse. With a stronger frame and stronger hydraulic cylinders it’s able to lift up to 5.1 tons. The trend to wider headers doesn’t stop at JD either.... (There are more and more 16 to 18 row corn headers in NA which weight more than 5 tons)

We harvested with the new 635R header with a cutting width for 10,7m. It was working excellent while our short test in wheat. For the 2012 season the Zürn Company will offer the Premium flow header 635 PF.


As already known there will be the powershift transmission with 5 steps for the header and feederhouse drive. According to the manufacturer it can transmit up to 185 KW.

The axial rotor is still fed by the tangential cylinder which brings the material consistently in an area of 270° to the intake of the screw-rotor. With an unchanged length and the same diameter, the rotor cone, screw- intake and threshing area is now significally heavier designed. The end of the rotor is taping and equipped with new convey elements.
For the new rotor, John Deere has spent a “variable flow”
For this purpose; the guide-rails in the separating area are adjustable from the cab in two positions. Moreover the area between threshing segments and separating segments were completed with a cone cover. For what reason? The material flow can now be adjusted actively and the duration of the material in the separating area can be influenced. Beside an increased throughput, these measurements shall reach a better straw quality. In contrary to the default setting the duration of the material reduces about 20% in “Advance position” of the guide-rails. This in combination with other measurements improves the swath quality and reduces the short-straw load on the sieves. We didn’t have the possibility to compare, but optically the swath made a good impression. Who doesn’t care about straw quality will use the default setting for maximum performance. As standard the S670, S80 and S690 are equipped with the premium straw chopper. Which is working with an additional feeding cylinder and 100 knifes. The change from swathing to chopping is done from the cab, by changing a guide plate. If you want to reduce the chopping speed from 3600 to 1800 rpm, e.g. for corn and canola, you don’t have to change a belt anymore. You just have to switch a claw transmission. Instead for an electrically adjustable guide plate for the straw spreading, you can know receive a radial spreader which is developed by John Deere itself. Recommended especially for direct seeding farmers and wide headers…
While swathing the sieve residuals are directed through the chopper and spread over the whole width. An integrated plate causes that there is no more chaff under the swath. But it’s still possible if you want to.

But back to the corn handling: Beside a longer upper and lower sieve, then residual handling needs a further investigation. The time when JD was led back the residual to the rotor, which caused significant performance reduction, is over. In the S680 and S690, John Deere is using an active re-thresher with a small drum (23cm with and 40cm diameter) which spreads the material over the full width of the machine. With a lever you can change the distance of the concave from 6mm for small grains to 70mm for canola and corn. With the active re-thresher John Deere says you can open the normal concave a little wider and increase the throughput. John Deere didn’t want to tell, if the rethresher is also planned for other models
The weight for the S690 without header is 18t depending on the chosen equipment’s. With 14.000l grain tank, 1250l fuel tank and 10,70m header you reach far more than 30 tons. Of course those want to be sustained as soil-protecting as possible. With appropriate tires, the combine isn’t allowed to use the streets anymore. The solutions are tracks, which could be obtained by different suppliers so far. For the 2012 season JD offers their own tracks. Specialists recognized that’s it’s made by Harrain. John Deere bought the whole know how and produces the 0,66m wide and 1,59m long tracks with suspension and pressure compensation among the rolls on its own. The width of the S690 is then 3,49m.

The most important for the future drivers in the end: The cab
After 18years the old cab deserved a change, even though it had some improvements during the last years. Without exaggeration the new cab offers a huge plus in comfort – maybe not even for green-blood John Deere drivers. The Space in height and width is more than enough even for tall people – of course in combination of the triple adjustable steering wheel and the seat with air suspension with adjustable arm control terminal. Beside a subjectively good noise attenuation
and the climate automatic there are other features for the driver: Full seat for the co-pilot and an integrated refridegerator and lots of storage possibilities. In addition you can get a Bluetooth speakerphone and a CD player with subwoofer.
The view on the header was improved by smaller pillars and the view on the unloading auger was improved by bigger side windows. The view was only limited by the huge greenstar display 2630 in the upper right corner, for yield mapping. But the display can also be mounted into the right control console. Steering system “autotrack” and throughput control “harvest smart” can also be operated with the small touchscreen in the right console which was taken from the 8R-tractor series. Together with the known driving stick there are nearly now wishes left… By the way: John Deere doesn’t want to waive the big display, although it’s only used for header height, speed and loss control.

What we also recognized:
- tines and tines-holder- in the separating area are now 2 individual parts. The holder is now welded on the rotor and if needed you only have to change the cog itself
- The 14100l grain tank can now be opened electrically. To unload it faster the screws are now driven by stronger chains and a new transmission. JD promises up to 135 l/s unloading volume.
- 405kW/ 551 HP constant power and 460 kW/ 625 Hp maximum power (ECE R 120) in the S690 come from a 13,5l – 6 cylinder engine with double turbo charger. It has a bigger cooler and a changed air intake fulfills with exhaust gas recycling and particle filter the Norm TIER IIIb (without Adblue technology). The Fuel tank has now 1250l
- The Prodrive transmission with automatic shifting and parking break and differentail lock is standard in the S680 and S690. Unfortunately the transport speed is only 20 km/h.
- The reaction behavior of the hydraulic system was improved. It’s now a load sensing system.
- The cab will also be used in the premium models of the T series, and in a reduced version also in the W series.
- Although the name of the combine didn’t include the “I” it was equipped with all knows i- systems.

Conclusion:
The new S series of John Deere include 4 models for the season 2012, with a maximum power of 625 hp for the top model S690. The new rotor was optimized for better straw quality and higher throughput. The new rethresher will also offer some more performance. Harrain tracks can now be ordered as standard, but more than 20km/h are not reachable, even with tires. Drivers will like the new cab, which offers more space, a good overview and good controls. We hope to report how the S690 is doing in the all-day routine soon. Until then, John Deere might have calculated the prize as well.


Greetings Arcus

What makes you think I needed it translated?

Not sure what you mean by Cog and Cog holder?

20km/hr?
Positively glacial.
Won't happen in NA.

You went to a fair amount of trouble, good job arcus!

20km/hr???? I hope that is wrong, I could see a reduced speed on tracks per say but on the wheels? I think that's a typo, maybe they mean 20mph?

Look at the last paragraph...

Its says 20km/h, even with tires. Its unusual that a german magazine uses mph... and I dont think they investigated it badly, since they emphazise it 2 times...

20km/h is right.But it wont be 20km/h in NA.Unloadspeed of 3.8bu/sec is pretty impressive.

Challenger, Massy Fergusson and Fendt offer 165 l/s.

Claas officially only has 120 l/s ... but I know that you can put some more through. Guess its the case at all manufacturers

Not a single non metric reference in the article and mentioned twice and emphasized, it's not a mistake on the part of Profi Magazine.
1/2 of what current NA units do, I repeat, not a chance!

those are some lame tracks compared to lexion, there so small. i could get 900 dual metrics and get more flotation. they better be bigger here. and will the power be less in the USA like the lexion 770 and the old john deere models?

USA/Canada lexion 770= 523-563hp
Europe lexion 770= 532-585hp

john deere 9870= 440hp
john deere s690= 530hp
