Running a hydraulic pump off of the front pto on a 70

I agree with the no about the two stage pumps. They for log splitters. Low pressure high speed first stage until you hit the wood then pressure almost doubles and moves very slowly through the wood. All heavy equipment use gear pumps just much larger than the ones we're talking about.

No need for a cooler, and you don't need a very big reservoir. You could likely use the rear end as the reservoir, but that is up to you. I would. I'd just add a little more oil to it if needed, or add an extension to the rear cover. Or you can just use an external reservoir. Just figure up how many gallons you need for the cylinders and make it 4-6qts bigger. That should be fine.

A two stage isn't just for log splitters. They have other applications. It's just not needed in this application.

Not all heavy equipment use gear pumps. Some do. About all use piston pumps now days. Have for several years. Gear pump is a gear pump. Has nothing to do with the size of the application. Just the type and demand of the system. In this application, it's a low cost choice. Piston pump would be expensive, but much, much better. Except for the fact that most of them can't suck, and have to be charged. Some can, like in a JD tractor. But that's one of a few examples.
