JD T670i thoughts

[gjm]

I'm looking at a 2011 T670i and wondering what current users/operators thoughts are. Output, sample, losses, problem areas etc, and would you have another one? It's a 25ft cut, hill master with prodrive. Thanks in advance.

I saw that, I actually had a shot of it at harvest time on its tour round the country, very impressed with it, output was tremendous for a strawalker combine. Unfortunately I can't afford a new one, I'm coming from a NH CX860. Just wondering what the previous ones are like in comparison.

why are you moving from nh

It'll play with a 25ft header, I think my T560i would cope ok with that. Mine has a 20 ft header ( small and steep fields and narrow gateways ) and I run at about 6-9k. I can get 40-50t/hr spot rate in a decent crop of wheat. I have loads of power so fuel consumption is good, I suspect the 670 should be the same. Sieve area is good, easy to get a decent sample and never ever get any sieve losses, just open them up a good two or three mm from book settings. ProDrive is the dogs danglies you'd never go back. It has the added advantage of diff lock and oil immersed brakes ( which is were they should be on a combine ). With the Hillmaster you need to fit speed flights to the header auger to get the best feed and ultimately performance. Also run with booster bar in for most crops except linseed. @martian has one but he's not allowed to drive it.

Not moving just yet, just looking. Had CLAAS, NH and JD strawalkers on demo at harvest and to be honest, the one I was disappointed with was the NH, in 11 years I don't see any improvement in capacity or output, it was a CX 8070 and was the only one our own combine made a better job than. No issues with NH though, they've served us reliably over the years, as I know a few local JD folk have been served well by theirs too, CLAAS as well. I'm just in the looking stage and JD were first back with a tidy second hand one. I'm also greenstar on the tractor so would tie in nicely.

The new combine is a different beast to previous models, in the middle of the day no other straw walker machine will touch the Deere for output, either side of that you might be wishing you had a lexion walker machine, grain losses aren't the best when you poke the Deere up a hill, not to bad goin across the hill with the hillmaster. Sample is as clean as you want it or as dirty.

I have a t670i pro drive with 30 ft header. I think 30 is a good match for it. normally it has plenty of power, only a heavy wheat crop in damp conditions with chopper on, can put it under pressure.
It makes a cleaner sample than walker NH and Claas (I buy a lot of grain local, for my pigs so easy way to see the difference)
If set up properly you can't overload the sives and no loss from there.
If you push it to hard it will have losses over the walkers, especially in barley early in the season. I have changed the rear tyres on mine for some huge once the lift the rear end and it has definitely improved it.
It has been cheap to run so far and never had any breakdowns in its 7 harvest (4 on my farm).

You will definitely like to pro drive, after trying that you will never go back to a normal hydrostatic system on a combine. It got loads of power on the wheels and pulls wery smooth witch means it will go up most hills.

If you chop the straw make sure it got the premium chopper.
I only have to normal 4 row one, and don't think it does a good enough job.

All over a good machine and I would definitely recommend it.

Jacob.

Just one more to show the rear tyres

what is limiting your current output? how many acres are you cutting and how many tons per day do you want to cut? perhaps you need to look at CX8.80 or 8.90? or indeed a small rotary like the CR7.90

I'm sure the new range of new Hollands will have upped capacity, (separating and cleaning area) but we're not in a position to buy new, had a quote for an ex demo CX8070, and nearly made me spill my tea. I'm just looking for a fresher upgrade from what we have currently, local JD dealer have been putting in a fair effort over the past two harvests, hence why I'm considering giving them a turn, if the deal is right. Cutting just over 900 acres.

 

[fergie35]

Oh I see. Yeah a newer Elevation machine will give you a fair capacity, i.e. late CX8070/80/90

nh are good at changeing cab and engine .. but capacity never changes

Couple of years ago jd modified the concave, fitting a gate half way round that can be opened or closed.

This makes a big difference to output and I would recommend you look for one with it fitted if possible.

 

[gjm]

Thanks for all your input, much appreciated.

I thought it was only last year. Was on the T series rotor. It's meant to make a difference in heavy straw and tough thrashing conditions. It wouldn't be on the MY11 one the OP was looking at, I think that would even be the old style cab.

 

[gjm]

Yeah, the one that's been offered is the very last of the older style cabs, not sure if that would've been able to have the mod or not. Technically I suppose it could have, as far as I'm lead to believe, the only difference between a 2011 and say a 2014 was the cab? I could be wrong. Obviously the new one for next year has had everything changed but the cab.

You'd have to change the T series rotor concave completely as far as I'm aware. Whether it's worth doing is questionable ( although a handy feature if included on a new machine ) as it is only a benefit in adverse harvesting conditions when you're trying to get the very last loose grains out of the straw. In more normal conditions it isn't used and in very good conditions some operators run with the T series rotor concave and third concave beater grate wide open to get even more performance.
If you want an idea about JD combine settings you can get a Go Harvest App, just stick in the model no and crop you want the settings for and it'll give you guidance as to where it should be set.

Has anyone run a CLAAS 660/670 against or alongside a JD T670? Had one or two CLAAS's offered into the mix around similar money? Not had much CLAAS experience so any input appreciated. Thanks.

I have been running together with a 560 (think it's mostly the same as the new one except for more hp)

In wheat and rape the Deere will run in circles around the claas, I barley they are more equal.
In wheat the Deere will harvest 10 tons more pr hour at simular losses.
