S690i and 770 demo

[Fish]

Could you still use more HP in your 7140?

Yep , always need more power, but we chop most of the time.

The old helical concave, from oz I guess, we use to run one in the 21 with the old grain rota, then moved it to the 23 which had an AFX rota, we also ran the same set-up as you, helical up front then a big wire followed by a small wire, but we found the helical is hard on peas and beans, so when we changed to a 7088 with a ST rota we never put it in and quite frankly never missed it.
Allways ran the 70 with small wire in p1 and a big wire in p3 and just changed the concave in p2.
Odd the you say that there has been little change in rota or concave design, in the 4 AFs we have run we have see 3 different rota designs and now the 71 has 6 light concaves and a 6 auger bed, it's a very different animal to the old 2188.

I think we should have a thread for Case another for Class another for NH another for JD.
My head is spinning with this swapping from CR to AF to Class Hybrid, to JD S series.

Yes lots of good tweaks thats how they sell us a new one, I like the ST rotor, and light concaves sound good but are not a bigger area are they.

Rotor diameter and length concave and grate area basically the same. But output trebled?

If the 1680 drives could cope with 400hp how far behind your 7140 would it be?

 

[Fish]

Not far behind I guess, but still behind.

Well of course there is thecombineforum.com which can be fascinating but tends to be a bit US based, took me ages to figure out what a Flagship/Heritage AF was. But it has helped with issues like interpreting the gobblydegook instruction book re programming the return to cut button!

I agree though an explicit combine settings guide would be really useful. I was very lucky to have a friend who had used an AF to combine borage when we started out, would have been a nightmare without at least an approximate starting point!

I learnt a lot on the thecombineforum Got some rollers for in the front elevator which stop back feeding. Simple but work great.
CHN even drill the holes in the feeder housing but do not fit them. The way these big corps work baffle me.

Demoed CR8.90

Cant really say it cut fit wheat any better than our 9 year old CR9080, but the header looks like it will cope with OSR much better.

tbh the CR8.90 is a direct replacement for a CR9080 so I would expect it to more or less be the same output. 2015's CR8.90 was 490hp which is what the old CR9080 was, this years CR8.90 now has 517hp so slightly above, but would be considered the CR9080 replacement.

 

[franklin]

Yup, we were trying it to see if they had fixed the things we dont like about ours :-

a) crappy feeding of OSR into header,
b) general unhappiness in cutting less-than-fully-fit wheat,
c) weak point where elevator attaches to front of combine,
d) lack of capacity for straw to get around PSD

The alternative would be to just go and buy another 2nd hand CR9080 and run the two together. NH reckon the newer header is *much* better in OSR. Not sure it will be enough of an improvement for the £££ it would cost to change.

I have the latest header, and its better than the cheval on the old header doing OSR.

Sounds like Nh are trying to do the same as Claas did to Clive and Lee a few years ago and they did to us along time ago, by saying a narrow bodied combine is the same output as a wide bodied combine because it has the same Hp. Sadly this isn't true it is like comparing a 6 cyl and 4 cyl 150 Hp tractor they are completely different animals with different pros and cons.

But the updated varifeed header is the next step on from the original and in my amateur opinion the best header out there whether painted yellow or red.

Havent had any quotes in yet, so will see. Plenty of options, and plenty of time before next harvest.

Wasnt trying to compare the 760 with the CR8.90 - its just that those are the two demo machines doing the rounds. I doubt it would be fair to put them side-by-side and I dont expect the prices to match either! Suspect the cost of the green one would buy me a massive continuous flow drier and that 2nd 9080

 

[Wiking]

Is Claas that much dearer than NH? Been a long time since I saw any quotes

 

[faircomment]

I was lead to believe that the new Holland would be dearer than the same class machine ? Interested to hear

 

[Honest john]

With all these model nr changes on both NH & Class it is like driving though fog at dusk.

I would be interested to know the answer to this too! I will be able to tell you in 12 months' time when I've got quotes for both myself.

 

[franklin]

Will let you know. Have asked for quotes for both the demo machines that came.

 

[Wiking]

Which combines can do 40km/h on the road, I think the new NH's can with tracks? Maybe Claas aswell? Would be nice to not clog up roads completly when moving about.

Will you start a new thread about it?
Decision making behind choices etc.....

Noo! This thread has at least 100 more pages left in it!
