I'm pumping water with a 16" crisafulli on 540 pto supposed to use 85 hp but needs over 100. Tractors don't hold up, pto's go out. What is the strongest 540 pro tractor out there boys?

One of the simplest PTO setups is on the Allis Chalmers 190 or XT190. IT just drops down right at the front of the transmission and goes out the back on the non independent models. They would be what I would call "live PTO" you used the hand clutch/Hi-LO to stop the tractor and keep the PTO going.
You can find AC XT 190s worth the money for just PTO work. Good ones are in the $3500-5500 range.
When 100 HP was enough on manure lagoon pumps they where used a lot around here for that.
The other way to do it is to use a much bigger tractor that will not be struggling with the load. They would naturally have a stronger designed PTO to handle the higher HP.
Am example would be a JD 4430. Here you have 125 PTO horsepower. That would be far heavier than a 85 HP tractor's PTO.
You did not mention what brand you "like" so the higher PTO HP equaling a heavier designed PTO would hold true on just about any brand.

Yeah, I would say 4430 or 4440 (my personal choice). I'm not convinced that the newer models with the flip around pto are as strong. They may be, but I have fought with that flip around shaft on the 7800 all summer.
A 4440 has the 466 - it won't even know it is back there. Buuuut, I'm an IH guy too, my choice there would be a 966. Right at 100 horse. Good tractor as well. More "simple" but that is often a good thing.

As far as I know that 1586 has a 1086 PTO. The 1086 still had a 540-1000 PTO. 1486 and 1586 were 540 only but a lot of 1486 owners in my neck of the woods where we have livestock and the need for more PTO use had a 1086 PTO put on their tractor. Never heard of a 1586 with a 1086 PTO but that's not saying much. LOL. Jim

The interesting thing is the reason the 1000 RPM PTO was made available because the 540 PTO was not designed for those 100 Horse power loads. Way too much torque on a 540 shaft !

what is a flip around pto never heard of it but don't have newer tractors
Have to agree with Jon here. My experience is with 1070, 2290 and 2294. For the higher HP applications here we have 1000 implements but the 540 option is there with these models.
One caveat using a Case on stationary PTO work. There are warning tags which may be gone by now. When you back up to the working location PUT THE POWER SHIFT BACK INTO THE FORWARD GEAR. The way I understand it there are a few bearings that lose their lubrication when in reverse.

The newer Deeres use a stub shaft with 540 on one end and 1000 on the other. Flip the shaft end for end and it shifts the internal gearing for the appropriate speed. Early ones had some issues and there were updates.

GRRRR! I meant to say 1486-1586 tractors were 1000 RPM only.

that what I had on 4010 and 4029s just did not know thats the name for them still have a shaft on my shelves
John,
Could you describe how the tractor's "PTO's go out"? The problem could be in the pump instead of in the several tractors that went bad running that pump. It's hard to tell without knowing the pump or seeing a picture of the setup. Some possibilities to look into are:
Binding in the pump or the pump's drive.
PTO joints that are out of phase to each other, creating a vibration and knock every half revolution.
Worn or badly misaligned PTO shaft.
If there is a belt pulley mounted directly on the tractor's PTO shaft without any other support bearings, it could be putting too much side load on the tractor's PTO shaft. PTO shafts are designed for torque loads only, not for heavy side loads like the old belt pulleys were.
Too much restriction/back pressure on the pump's outlet, causing the pump to use more power than it should.
Have you tried changing pumps?
If the pump manufacturer is still in business, check if they have a website, or call them and describe the problems you are having. It may be a common problem with that pumps.
Again, it's hard to do more than speculate without knowing the setup, please post a picture of the pump drive.

In the years I worked for an IH dealership I don't think they received any new 1466/1468/1486 tractors with factory PTO units. We installed the PTO kit for a 1066/1086 tractor while doing the pre delivery set up on them. We didn't sell to many 15 series tractors and about half of them were ordered in with a PTO unit. I can recall changing one of them to a dual speed before it was delivered.

We bought our 1486 new with 540 and 1000 PTO, all our 1566 and 1586s only had 1000 PTO.
You'd need a 200-250HP tractor for that to work.
Horsepower is based off RPMs. Run the tractor at half speed, and you are making something less than full power. Possibly less than half power depending on the HP curve of the engine.
At 1/2 of rated full load RPM let's say the tractor does make exactly half its rated HP. So to get 100HP, you need a tractor that makes 200HP at rated RPM.
