I posted earlier just before this board changed it's format so the post may have not appeared for long.

I wonder if anyone knows why the hydraulic pressure at either of the two output manifolds of the hydraulic pump is around 1400 psi and only about 400 psi at the output feeding the implement line to the draft-o-matic. Both readings are taken directly at the pump outlets (one meter connected to the side manifold and the other to the top output). The draft-o-matic is not connected when the readings were taken so it is something within the pump itself. I suspect that there might be a bypass on the top outlet but there is nothing shown in any of the manuals.

Thanks
