Comparison Which manufacturer has the highest HP true HST tractor?

[Bavarian]

Also MF has the very same transmission.

No. The Dyna transmission in the MF is different to the Vario in the Fendt. At a certain size, they share the same engine.

This was a big issue for me, and my understanding is JD always had a slight lead here. I bought a Kubota L5740 and cross shopped the JD 4R equivalent six years ago, wanted the most power in a hydrostatic unit. I find loader work so much easier with a hydro, better feel through the treadle. I'm now learning on my first powershuttle since I could not go larger with a hydro. To me the PS is nowhere near as easy or convenient to use. I don't care a whit about efficiency, I'm a low hour hobby farmer who wants convenience and usability, not 5 percent better fuel mileage, and I scratch my head why the manufacturers don't produce a model for my "niche" in the market.

My understanding is IVT still requires a powershuttle style forward reverse lever function. Also my understanding is that hydro is the only way to change direction without using one's arms. I have a bum right arm, losing my grip literally, and having floor controls worked really well for me. I explored this same issue a few months ago when buying my Massey recently, and the market hadn't changed, still stuck in the 60's. I think the first manufacturer that brings out a 80-100 hp hydrostatic model will sell a bunch. But they must have done some market research here, so clearly this is just my opinion. Or wish...

I have always had hydrostatic tractors. I did use my neighbors Kubota M7040, which was power shuttle. The power shuttle allows forward reverse direction changes with a lever but still requires a clutch to stop. I don't mind the shuttle lever but would like to avoid needing a clutch. I also use a power shift dozer. This is a torque converter connected to a manual transmission that allows shifting speeds or forward-reverse without a clutch. Lower the throttle and apply brake and the dozer stops thanks to the torque converter. Is there a 70 - 80 hp tractor that doesn't need a clutch similar to the dozer power shift? I can't think of any having a TQ. How do CVT tractors work and how have they held up?

This follows up the OP's original questions but if not appropriate feel free to move to a different thread.

As mentioned Fendt has a completely steepness transmission, iss a dual hydrostatic and mechanical transmission, MF also uses the same gearbox from Fendt

20 m/h to 60km/h steepless.

Suppose such transmissions will become more a available, or more likely the electrical transmission and electric PTO will be the dominant technology, electric PTO has huge advantages.

There seems to be only 3 tractors available in that class. The Case/New Holland with their version of 55 hp cvt or the Yanmar.
The above mentioned Fendt 207 Vario plays in a different league. It's more comparable to the JD 5R series. The 200 Vario series isn't even offered to the american market on the Agco website.
Regarding a tractor test report in Europe, the sales price is north of 100,000 Euros. A price range, where a Gran L customer won't look at.

IH made several over the 60HP range even up to a 1066 which was detuned to around 105hp if i remember right they changed them to the Hydro 100 and then I think the 186 after that.

Yea yea i know they are old and less desirable due to the creature comfort cabs being more noisy and not as many cool buttons as todays options.

I have never ran one so not sure of how the hydro part works if its lever or foot controlled. Nothing that couldnt be made into a pedal with some fabrication if not and desired.

I think they ranged in power from around 50 up to 105hp PTO HP I think they made about a dozen different models from utility to row crop chassis. Cab and non Cabbed versions. From what i remember most of the things i read were the people that had trouble with them overused them and got them hot, the people that used them for utility/loader vs row crop farming had the best luck and loved them, most got 25 yrs at least in those applications if not longer and loved them - there are many still out there today and a few folks that rebuild the hydros - pertaining to the marketing around new ones in that hp range my guess would be the same, cost vs purchasers - if they cant make one that will fit in that segment that will compete $$ wise for the amount of people that would buy, no manufacturer will probably venture down that road.

I just sold my Ford/NH 545D industrial Tractor/Loader. It has a shuttle lever with a torque converter. Not clutch operated... No clutch to be found. They don't make them anymore. I think 2001 was the end of the line.

Easy to operate... Not as easy as HST but not bad. Crazy strong loader.

2 different names, but same transmission, same for Valtra. AGCO owns all of them as far as I know.

Here is a lot of info on the IH hydros,
I have worked a 656 gas, a 1026 diesel and a Hydro 100 then the 100 got a turbo added to it, that was to get the pto hp back up to match a 1066.
None of them used a foot feed for the control, it was a lever that you slid ahead for forward and pulled back over and down for reverse.
They did have a foot pedal that was called a foot and inch valve it interrupted the pump swash plate control and acted as a foot clutch.
I enjoyed them for lighter work, they were handy for light drawbar loads and pto work.
The heat and fluid changes or lack of did them in, especially when used for drawbar work.

The MF DYNA4 is a powershift transmission, shifting gears. The Vario is driven by a hydrostatic motor.
