Gettings 3pt splitter working with remotes

[scottn]

Just got a little 25hp, 70's era Satoh S650G. Three point is controlled with a valve block on the side of the pump/tank. A swith block exists on the front of the pump/tank which says "Lock-Tilt-Plow". Remotes were screwed into two ports on the top of this switch block.

With the switch on "Lock" and the 3pt arms fully lifted the remotes receive pressure. Using the valve on the splitter the cylinder extends, but will not retract.

Here is where it gets strange. When the hoses connecting to the remotes are reversed. Nothing changes. Still extension but no retraction.

I am a novice with hydraulics so and wisdom you guys have would be appreciated. Thanks.

both lines were a pressurized supply. Using only one and returning fluid to the resivour via the filler plug works.

The two pressurized supplies are not identical, but one does work properly with the three point arms.
