I love my 3ph splitter. I run it off a Zetor 7745 that has a 30 lpm pump, however, I generally run the rpms much lower and I'm only likely at 15-20. It has a bit of a smaller cylinder, with a thin wedge. I paid $750 Canadian for it and a snowblower (used obviously). I place it on a skid and leave it on the ground, as I find there is too much sway and bounce if I use it in the air. It is small and light enough that two or 3 people can load it in the back of a pickup (ie, no trailer). The tractor already has 9000 hours on it, so I'm not worried about that, and I appreciate not having another motor to maintain. The tractor sips fuel at 3 litres/hour. I've also run it off a 1025 JD without issues.
In theory, my only thing I don't like about it, is working so close to the ground. I should make a stand for it. However, it makes it easy for the larger pieces I commonly work with. I split 12 face cord last year with it. It just always works.
I use IBC totes, and generally have a second tractor around. However, if I don't, I can easily throw into 4 bins, which is time for a break anyway. I do expect them to be better value than a gas version, either by price or quality.
