Which Brand/Model has largest HST Tractor?

[Hay Dude]

You can call it a clutch pedal if you want but there is not dry or even wet multidisc clutch in those tractors. They just have a hydraulic damper where the clutch would be against the flywheel.

Most companies call them inching pedals to denote the difference in how they work but the end result(tractor not moving/or inching forward) is the same. And yes you have to hold them to start as a safety feature in the same manner as well

Yeah, I’m aware as I operate them every day. I bought them used from Fentdt/Massey dealers. Only reason I call it a “clutch” pedal because the owners manual, operators manual and the dashboard “% clutch pressure” readout calls it a “clutch”.
Trying to explain what the pedal does with a paragraph of words is a lot more difficult than just calling it a “clutch”.

That‘s why the manufacturer does it.

The pedal in those forces the transmissions hydraulic pump to zero stroke and holds it there in not allowing the speed selctor to control the pump. When its at zero stroke the transmission output shaft does not turn because the ring gear on the planetary is allowed to freewheel.

Yes I know. You can also use the left handed “reverser” to go to neutral as another strategy, but the tractor will not start until the “clutch” is depressed.

Its a fendt designed and manufactured in germany transmission. Its shipped to france where both of your tractors were built in the same plant. They are basically the same tractor except the Challenger could have a 6.6L Cat in it depending on its age and the MF has a SISU diesel engine. HP ratings are different on the engines. I think the MT575B is the one with the exact rating as the 7495. MF, challenger, fendt, sisu are all Agco.

The Challenger has a Perkins in it at 135HP
The Massey has a Sisu turned up a lot higher about 190HP.
The cabs are a bit different, too.
I’ve been running AGCO equipment for many, many years.

I run the AGCO CVT tractors because they have a lot of German Fendt in them, but sell for much cheaper. I find them to be a bit complicated with all the wiring and electronics, but otherwise a great value when all you can afford are used tractors.

Greetings,

I'm curious what the largest (weight, lift capacity, etc), most capable tractor is on the market today with an HST transmission? Are there any nearing the Utility class size in weight and performance? Our last tractor was a Kubota L6060 which is still on the smaller side.

We are purchasing a small hobby farm with 40 acres hopefully as we prepare to retire from the military. I've had 2 significant knee surgeries so I'm either looking at a large HST or a power shuttle tractor because my knee doesn't hold up well to clutching anymore.

The CVT tractors are fingertip control. Mine have an “automatic” mode where it takes forward & reverse one step further. As you move your fingers forward, the engine will increase RPM “matching“ engine power to the operators desire for additional speed/power.
You can pretty much operate these tractors with no legs 90% of the time.
Pulling back on the reverser slows the tractor down. If you need more braking power, the brake pedals are there to stop you instantly.

If your knees are shot, a CVT would actually be better than a hydo. It may be harder to find a small CVT tractor than a small hydro tractor. Most CVT tractors start at about 100HP and go up to several hundred HP.

All of the power shift transmissions with reversers or power shuttles have a low "clutch" pedal pressure required.
Most of the ones that I am familiar with either have just a rheostat and return spring or a hydraulic pressure dump valve and return spring.

I said it was ok to call it whatever you like. After the Allis engineers retired the newer tech writers and field engineers probably got tired of arguing with the farmers.

Cat or Perkins, same thing. Perkins knew they were not going to make emissions coming up and Cat wanted its own small engine instead of buying them from Mitsubishi.

So cat purchase Perkins in 1998. They redesigned the head/turbo at mossville tech center and put a cat fuel system and ECM on it.

The go down the same line and it’s just painted different colors depending on what brand it is.

For the OP:
Here’s the arm rest finger tip CVT control in my Challenger. Massey looks exactly the same. If you can move this controller forward & backwards it speeds you up or slows you down. This along with the small reverser handle on the left of the steering column and the steering is about all it takes.
The small button the a gear around it and an “A” inside the gear is the “auto” mode where the throttle response is directly correlated to the CVT fingertip controller demand for more or less ground speed.

OP have a look at the JD "power quad" in the 5000 series. There is also the JD IVT (similar to Hay Dudes tractors) gearbox, however I think they may be to expensive for a hobbist farmer.
In general just look for "Wet Clutch"gearboxes or hydrostatic tractors.
Could you tell us some of the tasks you have in mind? ie topping ,bale stacking and feeding,( I recommend 60hp minimum and aim for 90 hp if you can).
Locally 90-120hp is the volume market and there are more options new or used.

You haven't given any indication of your budget, ie new or used market.
If the budget allows I recommend loader supension( smoothes the ride and reduces shock loads on loader and front axle) 2 rear scv's minimum and 3 or more if you can get them.Hydraulics. Go close circut to lift AND curl at same time. Open circut is lift OR curl.
Also look for the largest hydraulic pump capacity.
This will help future proof your tractor.The trend is for attatchnents to go hydraulic.

Oh, =Ohio? look at cab for snow clearing. If you get a cab Definately get AIR SEAT, not mechanical. Note there are 3 typer of air seat, 1way(up/down), 2 way(up/down and fore/aft{your back will thank you when towing trailers}), and 3 way(up/down, fore/aft, and left/right) You need to ask.

I’m thinking he’s looking for “biggest for his property”.
For 40 acres, I’d be looking in the high double digits with a CVT.
Maybe 80HP? I just don’t know if, or what brands are available with a CVT that small.

I know AGCO has some smaller CVT’s. Maybe at/ or a little under 100 HP
