S790 John Deere combine

[Elliott]

Anyone running one or another model in the range? Is there much improvement over the s690?
Thoughts on the draper header?

 

[Elliott]

Someone must have one! We used to run a s690 so looking seriously at a s785 as the area has dropped a bit. Had a quote for contract hire. Which raises another question. Are people still managing to contract hire below 50k a year on a big machine? Maintenance all in.
All you have to do is fill with diesel and insure it.

 

[dirty harry]

I’m running a 680 but that won’t help you much?
50k/yr sounds v expensive though?
I asked a similar question a while ago now about the jd 4040 sprayer & never had a response either?
Sorry dh

Ah no worries. Yeah does seem expensive. I was reading a thread on here a while ago where @Clive was managing to get it well under £50k for a 770 Lexion. Few years ago though.

Can buy one for 300k,why would you hire one for 50k per year?

 

[Fraserb]

Know of one farm that bought one to replace a lexion last season, they've bought another 3 for this coming season so must have been happy enough.

50k hire is under £20ac which with just driver fuel an insurance on top is pretty hard to beat if you have a fair bit of work to put through a machine these days

I’ve not had quotes recently but I believe you are looking at over 400k for a big Lexion now - then you have to service and run it each year which would be 5 figures of parts and service easily

I doubt you can get sub 50k hire deals now on such machines ?

Under £20 acre if your cutting over 2500 acres.

I looked hard at a S790 to replace a 6 year old S690 2 years ago. The only difference was the auto settings and grain quality cameras. The rest of the engine & threshing system was exactly the same as the 690. I have no idea what tweaks they have made for the 2019 model.

Well that’s what these big machines do (and more !).

Machines that have lower output are cheaper

Yeah we’re looking at about 2500 acres

Yeah the sales pitch was basically a refined s690 and a new header. Our one never had the sieve mod which increased the sieve area apparently. Output was a bit low but it was reliable and nice to operate with good integration of the gps, yield maps etc.
What did you go for in the end?

 

[wuddy]

No personal experience but a farming friend got one last year s690 with draper header replaced a lexion. He has bought another 2 this year to replace 3 lexions believe one 790 and another 690 one being JDs demo machine but not sure which one!

 

[Elliott]

Interesting. In what way did the Lexion do better?

 

[Elliott]

Ah sorry are you meaning output rather than yield data etc? In which case yeah the Lexion is definitely a higher output machine.

I'm not aware of the sieve mod but sieves were never the limiting factor on my S690 anyway. Rotor losses were, except for osr. I was cutting up to 3100 acres /year with it and that was more than enough even with a good spread of crops. 2500 acres sounds about right. It was a cheap combine to own and reliable overall, even if the output was disappointing (not helped by 3-4 weeks of rain stoppage during harvest every year). I went for a New Holland 9.90 because I felt it was bigger, had reasonable hillside capability with the tilting cleaning shoe and the rigid chassis should mean better chopped straw spreading compared to the JD Hillmaster.

 

[dirty harry]

The seive mod....?
We put the modified seives in our 680 this time ( they’ve been sat in the shed for 4years) to try it , basically the same but the back 5-6” is manually adjustable aswell, not sure if it made any difference whatsoever to be fair?
Jd dished them out foc 4-5yrs ago.
I guess the new ones come with these new types seives but haven’t looked in the back end of one to see?
It seems to be the seives that limit mine (& it’s hill master) especially this year with v dry grain?
Cheers dh

 

[Brisel]

Mine did have the manual sieves, so the dealer must have fitted them when they were available.

 

[Elliott]

Yeah I think it was just a pre sieve type thing like you say.
They have a damper on the concave now to stop the banging in damp crops, the sieves are aluminium rather than steel, feed accelerator has different teeth.
Does anyone run a protein meter on the combine? Think Jake Freestone has one on his combine. Next instruments??
