Removing Power Beyond

I have a 1980 4640 that has Power Beyond hooked into the center hydraulic hub between the SCVs. I removed the hoses and put in 2 plugs, but now my 3 point hitch won't operate. What am I missing? Obviously there is something else I need to do to remove Power Beyond. BTW, I will never need the Power Beyond.
TIA

It sounds like the hitch is l bypassed. A good while ago, someone had a post on here about their snow plow and it not operating because the fluid couldn't finish the circuit.I can't find it . If memory serves correctly they then looped a hose to finish the flow circuit and it worked. I sent you a pm. bordercollie

I suspect that the two hoses are supply and return lines...at least that is the way it is on my Kubota...try plugging the in to the out.
