John Deere T670i combine

[heyfarm]

What are people views on the t series combines and x series headers. Been looking quite hard at them. We would be moving back to a walker machine from a claas tucano 570 rotary. Pros and cons please or anything to watch out for.

Why the move back to walkers Will? Not like the look of the new walker Lexion?

I know someone with one ,it seems slow and unreliable but could be down to servicing etc

We have looked at it and staying with a rotary, but the jd threshing system seems better.

We had the previous generation t series, was an animal in osr, really good in wheat, and average in barley. We demoed the new one along side ours, same field and ours was doing 4km/h with 25 ft header, new on E same speed and 30ft header.

There’s a guy on YouTube “It’s a farming life for me”. Has plenty of videos of him operating and servicing one.
He seems to like it and get decent output.

I’d not looked that hard but have just watched a youtube video on them and they look good my only worry would be what they would be like in a wet harvest the grainpan augers would take some cleaning and the over the top drum blocking maybe. Pity they sacked sharmans or I might have looked next time

We are using a new t670i this year. Had a 2012 model t670 before. The difference in output is staggering between the two. No time for a break if you’re carting in! Easy to set up, though it does work the straw a bit harder if that’s a concern for you. larger concave and longer walkers with extra step in them seem to make a difference. Got the power flow header, not the x so can’t comment On that. We’ve gone from 25ft back to 30 and forward speed is increased by a couple of k in all crops so far this year, granted only cut 180 ac so far though.

In general crops this year aren’t what they were last year. Not sure comparing the two years is that helpful.

That is true, but our OSR was good this year and it romped away cutting it. Also had a Comparison a few years ago in the same field with ours and the first of the new t670i there’s a clip on you tube of it Flying along next to me crawling along. Thomas Sherriff & co YouTube channel. The guts of the machine are so much beefier too, they really are a different machine even if they have the same number printed on the side.

That could explain the one I referred too,it is 08/09 year

 

[heyfarm]

We demoed one in 2017 and that went well. Very impressed with it. Hill master would be a big help too. Have seen a few issues with the 6X headers like the plastic skids under it and flow of crop off the knife and one had a lot of issues with the table auger.

What year did they change them?

 

[Wheatonrotty]

We run 2015 T560 with a 22ft X header. Get on well with it apart from crop flow in the header in short crops. We demoed a new 560 the other day and as others have said big increase in performance, I think the big internal change was around 16/17.
The X headers have been updated as well and are now smoother to improve crop flow.

 

[Farmer Bob]

Think it was 15/16. A few more changes made to them in 19 too.

 

[dirty harry]

I tried one a few days ago, as said above it wasn’t the greatest crop but all we had ready , we have a s680 rotary, I’d say output is probably 15-20% less than ours , (30ton hr vs 35ish in these crops ?) the new 730x header is excellent & looks v strong , the tracks look good, shame can’t have hill master & tracks, sample better with 670 & more straw than ours! Overall impressed but need to weigh up if it’s right for us going back to walkers, cheers dh

 

[T560boy]

What year did they change them?

A limited number of the new machines were first sold in the UK in 2016. That's not to say everything on a newer plate is the new type though, as there would have been some older demo machines sold after this date.

 

[Chris W]

Finally relented and swapped a C670 for T670 this season.

Been an easy season so not caused too many issues but I am not getting the output I had hoped for without throwing alot out the back.
(All walker losses)

Any thoughts?

Boost Bar out (cracking too many grains with it in)
Drum 800-850 (cracks grains if any higher)
Concave 15-25 depending on conditions
Both separator grates closed
Separator in fast speed
Sieves 7/16
Fan 1250

30ft flex draper running at 3-3.5kph in 10t/ha crops.

 

[homefarm]

We have a T560 and it is always walker loss which limits output.

Cutting higher helps 2 inches more stubble could give extra an kph but perhaps not the solution with straw prices where they are.

i have played with separator grate and sometimes having it open seemed to help, using centrifugal force rather than the mangle effect.

With this in mind perhaps i would try a faster drum and wider concave and go faster, this is where grain should be separated.
Are you leaving most of the chaff on the ears if not you are still over threshing it.

 

[Wheatonrotty]

Have you tried with the concave wider? Often run our 560 with the drum flat out and keep opening the concave till it stops cracking too much, use the booster if you can. You do need to push it on to keep it full so it's crop on crop rather than on metal. As @homefarm said play with the separator grates to see if it helps.
Should be able to get more out of it with some tweaks, we have a 30ft flex draper on our 560 and she'll sit between 35 and 45t/hr in a 10t crop. Limit tends to be walkers if rowing up, engine power when chopping.
