1850 Lower 750 No-Till jerkey droping drill

[DarrylMueller]

I have moved from California and settled on a farm in North Carolina, my manuals and still packed away. I have used this 1850 for18 years and used a lot of hydraulic attachments but nothing like this? So someone guide me to correct adjustment. I bought this John Deere 750 No-Till and getting ready to over seed pastures and hay with it. When I lower it it is jerky and the hoses jump. I think there is adjustments on the left side of the tractor for lowering one way cylinders but I am without a manual and forgot all that?
The drill manual talks about open and closed hydraulics systems I am not sure if this is the problem or it's an adjustment. I can post pictures of the control valves if that helps. I am using the right side hydraulic outlets, It raises the drill OK, but lowering is like it against the relief valve?
I also need the 3 point hitch for the drill hitch to be working.

Ok I found out that as long as rpms are 1500 or more it works fine.
So it was all rmp making it jerky lowering drill.
