John deere CTS
Hi everyone

Does someone know the big defference between JD CTS and STS
combines. The CTS has 2 rotors and was a big thing in
holland a few years ago. Why is there nothing over CTS in US
and CAN. At least not on the deere site. Why would one be
better than the other?

Greetings Jos;-[
Re: John deere CTS
ANd here the pisture of the STS type
Re: John deere CTS
Is gewoon een axiaal flow ?

Anders heb ik niets gezegd :-[

Voordelen zijn
Grotere capaciteit
(bijna)Geen graanverlies

Stro wordt aan de korte kant
Als het vochtig is wilt het graan zich nog wel eens om de
trommels wikkelen (vooral bij oudere combine, zoals de
eerste IH's )
Re: John deere CTS
Hmmm... Thats new! They used to have the CTS on there.
Anyway - the CTS has bigger capacity than the WTS, but the
STS has even bigger capacity than the CTS! The CTS used to
be the best at handling moist and green material, because of
a more thorough threshing, but I think the STS can do that
pretty good too now. (updates...)

Oh yeah - the engine is bigger in the STS - 12,5 litre ;-)
Re: John deere CTS

Jep in Holland they have the WTS wich is traditional and Cts
with 2 rotors and sts with 1 rotor. In some countrys the WTS
is called CTS. Thats to keep it simple ;-). I think they
ordered to many CTS stickers.;-) But it is kind of wierd,
that they don't speek of twin rotors in the USA, and NH
makes them too. But would you think a single would be better
then a double?

good luck Jos
Re: John deere CTS
Hi Joske!

Hmmmm. That sounds very wierd with the WTS/CTS mix-up... Are
you sure about that? Which countrys??
Ohh!?! In Australia the WTS (Walker Tine Separator) is
called CWS (Cylinder Walker Separator)- could that be the
mix-up your talking about??
Anyway - I have no idea of why they no longer advetise the
CTS in north america! The machine is still sold anywhere
else, as far as I know.

About the single rotor vs. double rotor:
You can't really compare the STS with the CTS (Cylinder Tine
Separator), since the the STS only use a single rotor in the
separation process, whereas the CTS only uses their 2 rotors
instead of the traditional straw walkers. In the CTS, the
material still has to go trough a threshing cylinder - just
like the one used in the "old fassion" combines. The tine
cylinders (rotors) in the CTS are just "a step up the
capacity-ladder" when compared to walker-type combines ;-)
(and the STS is one more step up!)

The way the CTS works, makes it a lot more gentle to the
material - it dosn't "crush" the straw as other rotor
machines do. It is also more capable of dealing with green
material, like if there is a lot of grass or weeds in the
crop. Rice too!!!
Traditional rotor type machines (Axial-Flow, STS, Twinrotor
and so on) cant work under the same conditions the CTS can.
Those rotor machines has greater capacity in good dry
material though...

Hope this answered your question.

Re: John deere CTS
Thanks a lot for your answers. I'm not that sure about the
mixed up anymore but if you google on CTS john deere there
come up some conventinal combines so thats why the
confusion. And if you go to and standard is US/CAN
they won't say anything about the CTS.

Good Luck Joske
Re: John deere CTS
The Deere CTS combine was the best machine ever invented for barley. You would push it till warning lights came on then back off a hair, IF you could hold on at that speed. One guy I worked for said he never did get to a point where the lights came on, said he never had the balls to go fast enough.

The Lexion "R" series are the same basic design as the Deere CTS combines, the Lexion was the best combine I have ever driven.
