I have an IH 606D. It has an after market 3 Pt hitch with an old Rhino BR 7 ft blade on the 3PH. I would like to add a few cylinders to the blade. There is one OEM Aux control valve bolted to the transfer block and other than the power steering, there are no other hydraulic controls on the tractor. Can anyone tell me about the hydraulic transfer block? It has what appears to be an overload valve on the rear end and two plugs on top. One plug is large approx a 1 inch hex and the other is approx 3/4 inch hex. Are these two for power beyond and/or a supply and return for additional control valves? Has anyone added additional valves to this setup? Any help here would be greatly appreciated.
