| Looking for some insight for how to hook up the hydraulics on a JD 1770NT CCS with variable rate to a New Holland 8970 without Megaflow.
I was operating the planter yesterday and I believe I am a little short on oil flow. When I lower the planter and the CCS fan and the VRD motors try to start at the same time the vrd motors try to turn but stop and I get a warning screen. If I stop the planter and let the ccs fan ramp up to speed and then put the tractor in motion, the planter will plant fine. When I get to the end of a round and lift the planter, the scv that the vrd motors are hooked to starts screaming when the vrd motors stop running and I have to put the lever in float to make it stop.
The ccs fan has a case drain returning to the low pressure case drain on the tractor. The return is going back to the SCV
The vac fans are teed together so they operate on 1 scv and they return to the scv with a low pressure john deere end with check valve to stop reverse flow.
The variable rate motors are connected the same as the vac motors.
Nothing is hooked up to the priority scv on the tractor. I tried to put the vrd motors on the priority, but when I engaged it the vac and ccs fans quit running.
Should the return for the vac fans and vrd motors be connected to the low pressure case drain also? the planter book says no, but that is for attaching to a jd tractor.
Would hooking the vrd motors to power beyond help the motors to run when the ccs fan is coming up to speed? (the tractor is not power beyond equipped)
I was able to plant, but I have to stop every time I lower the planter, that's a pain and it seems something is just not right about the whole deal.
Hopefully somebody has some sort of experience with this. TIA
