jd 1070

[Simpkins85]

I have a john deere 1070 and I am putting wetlines on it and I put a prince 2575 4 way valve on it and I think it has a nob under the seat to turn hydraulics off the the 3 pt lift arms I turned it off and tried to use my valve and lines to lift and lower my v rake but it didnt do anything but when I turn the nob under my seat on the valve I installed lowers and raises my arm anybody know what I have did wrong I ran my in line from a port on my hydraulic mainfold and my return back the housing so I am lost.
