John Deere T660 year 2010 with Command Center screen, experience ?

[SteveO]

Are those any good ? I see that older ones dont have that screen inside so it must 2010+ version ?

What problems they have and what to look after ? What do I lose if the machine is no "i" model ?

I know a lot about JD tractors but have zero knowledge on their combines but want to change from DF.

Thanks

Why not ring your dealer n speak with their combine guy to get the model spec / yr by yr changes low down ?

 

[SteveO]

Well, we all can do that and turn off forum then ?
I want to hear real life opinions, not dealer guy opinions. And I dont know personally combine guy and they are not so open for those kind of discussions if you get me.
They say mostly new ones are great, well I dont buy new combine.
They will not talk in details if you will not buy from them and they dont have one like I want.

People have T series here, I can talk a lot about Deutz Fahr problems and good series, you dont need to call the dealer about them.

Maybe your are my guy ? You do JD so I would love to hear your opinion on them.

I haven’t got a 660 but do have a 560i. Same engine, one less walker. I like the design of them, easy to get a decent output, parts a reasonable ( compared to a Claas ) and plenty of power. The 660 should be 371hp max and just over 400 with boost when you’re unloading. Fuel consumption is good as it never works too hard even when chopping. Hillmaster is essential if you’ve anything other than very flat land, prodrive is excellent if it’s got it. If it isn’t an i you loose things like yield mapping and harvest smart. To be fair I’m not keen on harvest smart, it’s ok but it’s obviously reactive, I reckon you can gain far more output with a decent operator being proactive.

 

[SteveO]

Thanks for your input. It is not "i" model so I think no Autotrac and all those fancy smart options. I would remap it to get to T670 power.
I have 101% flat land but it is Hillmaster
Would gladly trade it for "i" and pay extra.

So Claas Lexion parts are still more expensive ? Roughly by how much since all owners cannot tell how good Lexion is.

It does not have ProDrive if it is not "i" model ? That thing adjust speed or what ?

Thanks a lot !

We had a 670! for 6 seasons, ours went well and didnt give any real bother, output was really good in wheat and osr, average in barley.

Prodrive is the kind of gearbox, if its got a gear lever it doesnt have pro drive, as simon says your not missing much not having harvest smart.

 

[SteveO]

It does have gearbox lever, so it is stupidest version of T660
Comparing to Claas, what model is its rival ? Just to compare prices.

Im sure it would be a 550-560 lexion.

Theres not a lot wrong with the basic gearbox, the gear lever might seem a bit dated but its one less thing to go wrong.

I doubt you’d need to re map it if you’ve got flat land, mine doesn’t run out of steam even on our steepest of banks which have the Hillmaster exceeding it’s chassis tilt limit.
Prodrive is a programmable gearbox that you can select the max speed in one of two ranges. The only criteria is that speed 1 has to be slower than speed 2, you can switch between speeds on the move. For example you can set speed 1 at 10k, if you move the controller fully forward it’ll max out at 10, if you move it half way you’ll be traveling at 5k etc. It gives you greater rim torque at the wheels which is ideal if you’ve got banks. As far as I’m concerned the best bit about Prodrive is that it has oil immersed internal brakes.

I am thinking to remap so I can drive faster in the field. Probably delete emission crap also.
You look properly on combine capacity, tonnes per hectare, we look it as hectare per hour but that is not same, we have wheat 5-6 ton/ha and also 10 ton/ha, it is not the same.
Do they have problem with sieve or short walkers grain loss ?

I doubt you would run out of power unless chopping, we grow big straw crops and power was never an issue. It was always the walkers that limited my output but you could still push on. I used to run the concave a lot wider than recommended, sometimes up at 30mm in wheat.

 

[SteveO]

I do chop pretty much everything. Do they have big grain losses when you push them ?
What is a push for T660 with 7m header, 5-6 kmh ?
How much hectares can it make per hour, 7-8 ton/ha wheat ?

We would be around 10 t/ha in wheat, and 5 to 6 ton/ha of straw, it would be unusual for me to drop below 4 km/h usually between 4 and 5 k, that's with a 7.5m header.

 

[SteveO]

DF 5695 cannot go more than 3-4kmh in those conditions.
So you can get 3-4 ha per hour roughly in very good wheat ?
Where is the cap, sieves grain loss or drums ? It starts to lose a lot of grain or engine cannot eat more in the drums ?
I have heard that on S thr only problem in rapeseed and wheat is engine power, it can eat whatever you push it but engine is weak with 530 hp.
What is the sign on T ? I suppose a lot of grain loss like on DF.

I used to work on 3 ha an hour, anything extra was a bonus, it was almost always loss over the walkers that slowed me down, if you're chopping you could cut higher and put a lot less straw through it.

 

[SteveO]

That is why a lot of people say that walkers are too short on them.
One more thing, terrain copy of the header on DF is a disgrace. How does T perform in that part ?
I must go lowest possible in soybean harvest and there the header automatic terrain copy means A LOT so I need to know how it compares to DF, Claas or Case.

I always got on OK with it, the NH I drive now with 4 sensors and on tracks is better though.

 

[SteveO]

Reacts better or just copies better coz more sensors ?
JD has 2 or 3 sensors ? Middle sensor is very important on wide headers, I hope it has 3 of them.

Mine only had the 2, the NH has an easier time as the tracks give a smoother ride.

 

[SteveO]

Hm, that could be a problem on 7,5m, even DF has 3 sensors, middle part eats soil very often on wide headers if the sensor is not installed.
It has those C metal parts like loaded spring and it copies terrain ?
Does it have header slide for soybean ? DF has that option which makes the header glide on the field, I am guessing it opens valves for lifting so it can freely go up when you push it collecting soybean and other low grains. But it does not work on 99% of them
