While adjusting the lowering speed and the lower limits of my 3ph, I stumbled across the attached reference page in my owners manual. The text in question is highlighted in blue. Any chance this means that plug in the other attached pic (with the circle around it) is a port for rear hydraulics. I backed the plug off about a quarter turn and pulled the lift leaver back to the offset and fluid gushed out around the plug. If it is, what all would be needed to make this ready for a log splitter?

You cannot directly hook up to that port, BUT If your log splitter has springs to return it you can hook a hydraulic hose onto the test port on the side of the three point hitch cylinder cover and use it to supply oil to your log splitter, (or any other single acting cylinder. You would then use your three point hitch control lever to extend and retract the cylinder.

That "port" in the picture looks like the banjo bolt/fitting from the supply oil from the pump - you don't want to try to connect there.

There should be another port with a plug on it just under the front of the seat hinge coming out the side of a T handle valve (at least there is on my B7100), note: it's not the T-handled valve in your photo - that's to adjust the drop speed of the 3pt lift cylinder).

The T-handled valve is a diverter that changes the flow of oil (controlled by the 3pt up/down lever) from going to the 3pt lift cylinder to going to the auxiliary port.

If you only need extend, you can plumb directly from the port to the cylinder and use the 3pt control lever. If you need both extend and retract action, You can use an open center valve on your aux implement and return oil from your aux implement goes back into the transmission fill plug (you can use a T fitting so you can still fill without having to remove the hose.). Note: You still need to "turn on" the oil to the port by putting the 3pt lift lever in the lift position when you want to use the aux hydraulics.

Hope that helps

You are correct, I just went out and looked and sure enough the supply tube from the pump comes up from the bottom and is connected via the banjo bolt, I don't know how I over looked that:mad: And I don't have a T handle mounted on the cylinder cap, that was only a optional add on, so I guess I'll be searching ebay for that.
