Comparison Which manufacturer has the highest HP true HST tractor?

Gruess Gott.

Auf Wiedersehen dann !

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.

What transmission does that have? Our L3830 has the Kubota 12 speed GST transmission and you never have to use the clutch unless you want to.

ZF builds 2 different CVTs used for various European built tractors, Kubota M7 premium KVT for example. They also go in some McCormick, Claas, and CNH tractors. Similar to the Fendt, hydrostatic drive ring gear will take it stepless from 0.2 mph to 31 mph, but still forward reverse shuttle so much slower for loader work. However the bucket on our New Holland holds about 3 times as much as our L6060 Kubota and our M7 bucket holds 5 times as much so productivity is better with the larger ones if you don’t need the maneuverability. If you watch the Fendt on YouTube along with ZF, you’d swear they are the same. ZF builds the dual clutch for the 700 HP Porsche Carrera so you would think just slap that in a 200 hp tractor and go.

Don't know the model but it was a manual transmission with shuttle reverser. I remember having to use the clutch to creep up to a fence when loading round bales.

GST is just Kubota for power shuttle, at least on their CUTs. Wet clutch with a hydraulically shifted transmission. There is usually a dry clutch in there too, not that you strictly need it.

Personally I never got the feel for the engagement timing in the couple hours I ran a L3?30 GST my brothers father-in-law has. I ended up using the clutch a fair bit. Probably would have gotten mostly onto the shuttle lever with a few more hours of seat time. Good transmissions, but still a bit more of a learning curve than HST, especially for precision work.

Bavarian, I'm not really into Agco, but Dyna4 and Dyna6 are powershift transmissions offered in base Masseys, and the Dyna-vt option would be what is said to be same as the Fendt. So yes not all Masseys have a Fendt transmission but don't blanket statement it that they're not the same

Oops, I was not aware of the VT option. In which models is it available. There is a video on YouTube from the Millennium Farmer. He tested a tracked Challenger which apparently had it as well.
Possibly still out of price range for most of the users here on TBN.

Hey no problem, I think the smallest one would be in the 6700 series, and yes you're right plenty costly for most looking for a utility tractor. Deutz likely makes the smallest vario unit that's available in North America that's not classed as a compact tractor.

The only small tractor I have seen with a CVT is the Farmall 55,
then you have to step up to the 135 Hp range to get it again.

I see, well Deutz-Fahr makes the 5100 TTV with a SAME manufactured transmission and the 3.6 four cylinder in that model puts out around 70hp
