Hey HPP,
I was wondering. When were they first built, when were they given more power (for example: i was thinking there was a 612 with 120, 130 and 135 hp?)
And another question: When was that big beast of a 626 introduced?? was it co-operation with Schluter?? Did it had an MWM 8 cylinder engine?? What front axle bear such a huge nose??

The 600-range was introduced in 1976. 600 - 85 Hp (Can you imagine 85 Hp in that body!) 610 - 95 Hp 611 - 105 Hp 612 - 120 Hp 614 - 135 Hp 615 - 150 Hp When I started to work with Fendt in 1982 they were allready upgraded. I´m not quit sure when the 615 got the EHR as standard equipment. It was there at that time -82 but I think it was from 1980. Talk about pioneering! In -82 the range was: 611 - 105 Hp 612 - 120 Hp 614 - 145 hp 615 - 165 Hp The 610 - 95 Hp was still sold in some countries I think until -83 or -84, but we never bothered with this model in Sweden. Then there was sort of an inbetween-version from -85. That´s when EHR became standard equipment on all of the models in the range. 611 - 115 Hp 612 - 135 Hp 614 - 155 Hp 615 - 180 Hp It was at this time the 615 got the torque converter instead of the turboclutch. And, I think, in -88 the final version was introduced: 611 - 115 Hp 612 - 145 Hp 614 - 165 Hp 615 - 185 Hp. Since, at this time, many customers had become aware of the advantages of the torque converter, this was offered as an option also in the models 611 - 614.
Then, about the 626. I don´t know what front axles they used. (We never sold any units of this one in Sweden) What I do know is that it had a MAN-engine of 11,5 litres. The rated power of the 626 was 260 Hp, but maximum power, at around 18-1900 rpm was, much higher. It had a ZF trannie, 6 gears with a 3-step PS. It was a pure Fendt-machine. You have to understand that Hermann and Anton (Schlüter) were rivals at this time!. A nice thing about it was that you hardly heard the engine when you started it with no throttle, you almost had to check the rpm-meter to know that it was running! Actually the 626 was a later version. It all started with the 620. I´m not sure but I think it was 200 Hp. Later the 622 came, 220 Hp. And parallell to this the 626. You could order this machine as late as -86 but then you had to order at least two units.

Hey, HPP, thanks!! Yes, i can imagina 85 hp in that 600 body, we had a 2WD 600 on our land, pulling a 5 meter disc harrow. (the 612 my brother usually rides at the contractor was hired to someone else) In mudspots, the disc harrow didn't touch the ground than just with the supporting wheels, and the 600 would still spin. Too much weight on the front axle. Our 5245 had to do the work in the mudspots, with the 600 being more of a pain than actually pullling the machine. I was driving too slow, he said. i should shift to fourth gear. I did, and the chain wouldn't stretch. What i was doing, he said. i said i had it in low 4. A 5245 (50 hp 4wd) is not spinning like a 600, i said. "O.K, lets start over and try high 3." that worked out better. The year after, he brought the 615 with him. The 615 (4WD) had power enough, but still too little weight, and also spinned. The disc harrow was a second hand import from east Germany. It was too small for East german operations, the frame was torsed. So they used to have an articulated Kirovets or so in front of it, there. Hey, did the 626 have a torque converter or turboclutch? I think the torque converter is not too useful in combination with a powershift. Is this powershift tranny also used in the big Deutz, like the DX 8.30? and in current build tractors?? Was the ZF tranny special built for the 626? Sorry to say, but i prefer a Schluter. I think that is because my blood is red. I just love the prominent classic nose. Did Schluter also used the ZF tranny? They did use the MWM engine.. Kinda shared platform thingie perhaps, in those days?? I think the standard 600 series with turboclutch and 12/6 tranny wasn't that modern for 1976. But the Turbomatic E versions were characteristic and useful tractors, still having fans today. Even my brother is 'converted to torque converter' ha ha.. I wish the world had some more torque converters instead of powrquads and dynashifts. A major update for the torque converter principle is a three or four stage one. ( i invented it today, while driving a fork lift truck..) By adjusting the oil flow to 1 , 1+2 , 2 , 2+3 , 3 , 3+4 , 4 converter fans (mean those mills, not those guys, like my brother), we could make a semi-stepless tranny, with different ratio spacings between engine rpm and speed. You will say that's impossible, running two gears at the same time, but that's what torque converters are all about. It's dynamic, remember... the 600's needed more gears to have stabile PTO to wheel speed ratios, this semi-CVT/TC not. Just 6 speed ranges and the VTC I think nobody will catch my point, again (like with the Yoke), i will be stigmatised for having too much fantasy, be the paria, and a major transmission builder will run away with the idea when the market is ready for it. I'm not STOOPID, just pragmatic If one of those tranny builder guys wants me, let them mail, ha ha ha. I caricaturised my self. You should do that too, guys! we would know each other better than just in our nerd-being. Hey, does the Fendt Variofill turboclutch meet my idea?? And what about the Ford passenger car with Auto tranny with variable torque converter from the fifties?? it had two mechanical speeds, and two torque converter speeds. Greetings Renze. Good goan!!

Geeeee Renze! One day I´ll get time enough to go through, and think through, all of your ideas! To your questions: The 626 had a Turboclutch. The ZF-trannie was also used in the Deutz 8.30. As far as transmission goes these two tractors were quit similar. Don´t know however if the two had their own special version or not. The Schlüter also used this concept. And MWM, BUT! Schlüter also had their own engine!, in some models. I also like the looks of Schlüter. Had a lot of interesting technology, but as far as ergonomy goes they were outdated even when they were new. Don´t think you can speak about shared platform really. I think it was more of two rivals, both of them constantly looking at what the other did. (Talking about Hermann and Anton there). There was once a time when Anton Schlüter wanted Hermann Fendt to take over his business. This was at the time when the Schlüter Eurotrac was introduced to the market. Hermann told him that the only model Fendt could be interested in taking over was the Eurotrac. Not the rest. Herr Schlüter felt humiliated by this and went to Claas instead. The big topic at that years Agritechnika show was the talking of Claas taking over Schlüter. As you all know this never happened.
Last question (that I´m able to answer) - Variofill: That´s just a new version of the turboclutch. Used in the 3 biggest 800-models (not the 818 Vario!) and in Xylon. There´s some sort of storage room in the center of the clutch were most of the oil is kept at stillstand. This means that there´s little oil in the "working part of the clutch" when you start up. Thus the engine reaches higher revs faster. (Did that make any sense at all?)
Say, Renze! I really think you should take a trip to Denmark some day and visit the danish Fendt-importer. Alex, the guy who owns the company, has a huge span of knowledge (understatement!). There you could present the ideas you have. He would know what you were talking about! Just so that you shouldn´t think it would be a waste of time: Alex knows a lot about tractor technology, not only Fendt technology.

Hey, HPP, Thanks for your answers. Yes, i know what you mean when you explain the principles of Variofill. I already had an idea in that direction. (the name says it all) When there's less oil (=mass)in the turboclutch, there is less centrifugal power on the driven turbine, unless the oil has got more speed. (power = speed * mass) so, the variofill does the same as a torque converter, or does it only reach high revs earlier, and is not converting torque?? (well, all turboclutches convert SOME torque.) By the way, that variable torque converter, could be better a variable turboclutch, it better meets rpm to traveling speed ratio requirements. I meant one pumping (driving) wheel, and four motoring (driven) wheels. Hey, i will need to hypnotise that guy Alex. So that we can discuss lots of my ideas, and when he wakes up, he wont remember, and cannot run away with my ideas.

Hey Renze,
All of the Steyr 8160s that I've seen do not have a powershift. The front axle on my 8080a tractors is a ZF.

Hey Renze, you have to excuse us ignorant swedes, but Steyr always was an exotic breed up here. They tried to hit the market here for a while in the -60:s and/or early -70:s but never really made it. So, therefore, what ever components they used, was of little interest to us. Besides, it was quite a common view whenever the discussion on Steyr or not Steyr came up that they wouldn´t stand a chance with their ergonomy (0r lack of!) Now I´m talking early 80:s when some manufacturers (Steyr for instance) still had problems getting below 85 dB(A).

Hey HPP, the whole ergonomics thing was just a matter of dB(A)
