Would like to add a cart to the operation and use my JD8570 but it has no PTO and smaller capacity hydraulic pump. Can the hydraulics on these older tractors run a 12 inch cart auger or should I put a PTO in?

We run a J&M 875 with an 18" inch auger off a 25 gpm kit. It's a little slow in lentils and peas. You should have no problem with a 12". I ordered the kit from Avonlea Farm Sales in MB as Flamans was adamant the 25 gpm kit didn't exist, than was almost twice the price once they could be bothered to look into it (took about ten days to get a price...)

May want to consider how long you’ll keep the tractor, if a cart with a larger auger comes around a pto would be handy, hydraulics would run a 12”.
But can you get a pto for a 8570?

We run our 22" auger with hydraulics. The usual tractor on it has 57GPM so is fast enough. We have put our Case9270 on it which is like your 8570 for hydraulic flow. It works fine, just a little bit slower. On a 12" auger you should have no problems, if you go this route just be sure to creep the slidegate open or you will plug the auger, at least we have, on both tractors.

I ran a cart with a 20” auger, 250 bushels a minute in wheat and 300 a minute in barley and canola. This was a high capacity pump on a Quadtrac. Have since bought a 4wd with pto, no comparison 600 bushels a minute in any grain. Still have pump, it’s for sale, used it for two years.

Slip clutch is right, if you go hydraulic than you need a double hydraulic pump. I owned a 946 and 2375 vers and used them with a 875 j m cart and both performed poorly when unloading heavy wheat or soybeans even 42lb oats was a chore. When you have multiple combines going in 170 bu acre oats you cant be wasting time waiting to unload, its hammer down time. Instead of going to a pto I switched to a 9530 jd with 88gpm. Not saying its better than pto but, Yep that fixed the problem. If you decide to buy a 2375 vers it will work on that type of grain cart but the performance of the hydraulics will not be like a pto. PTO is still the best. You will not regret getting a cart.

I built my hydraulic kit for my graincart last summer and it turned out great. I can't remember what the hydraulic flow on my T9.560 is, but it ran the cart no problem. Unloads 900 bushels at 2/3s to 3/4s of PTO speed. I can make a **** of a mess already with that, I can't imagine how large of one I could make with a real PTO.

What type of grain cart and do you have twinflow on the T9.560 or just regular 55GPMish pump?

We have an Elmer's with PTO but honestly never max it out. Would be neat if PTO wasn't necessary because every tractor made lately has 55GPM hydraulics.

I bought a 2009 Elmer's/TorMaster(?) Haulmaster 888. I can't remember the size of the auger, but I think it might be only 16" but has a belly drag auger as well. I'm just using the regular pump. I wasn't even sure if its 55GPM. I feel like it might be less than that. I built the entire kit for $2500 with a namebrand pump. If the ebay seller had sent me the correct pump(they had the box mislabeled and sent me a pump with almost 2.5x the displacement) I would have built it for less than $1000.
