A man driven plow either provides PSU maintenance or a + to the pool formula. A animal driven plow will create a potential source. The size I'm not sure, I've never made one. I'm assuming they follow the same rules of tools, and I'm pretty sure the animal plow can be used to create only 1 psu source per event, would stand to reason.
