| 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

ROCKHAMPTON CENTRAL QLD | The first thing I would do is check your flow/pressure at the scv's just to make sure every thing is working OK. |

Northeast Indiana | I went through the same type of problem last yr. I have a 8770 non mega flow hooked to a kinze 3650 12 24 with vac, hyd drives, and a hyd air compressor. You lose some hyd flow with the super steer front end. Long story short I put a aux hyd unit off the pto. I put my two vacs and the air compressor on the aux unit and then just had three scvs out my four used on tractor. Aux unit is 16 gal/min. |

| This spring I had all the scv's flow rated and detent adjusted. Flow rate was 22-24 on each scv |

Richardson county Nebraska | I honestly don't think you can do it without pto pump. Have a 8670 on 1770NT 16 row. Ours is finger pick up and no ccs with dual hydraulic drive. If I'm pushing population on a hot day hydraulic flow will limit my speed. Also have to about stop to wait for planter to raise. Take note of scv's the priority is not 1-2-3-4. Goes 1-4-2-3. We ren hydraulic drive off 4. Ours is mega flow ready, but new holland no longer offers parts bundles too update, have to "piece" it out $$$ OUCH. |

Tennessee | You need a pto hydraulic pump. We run a 1770nt with our 8970 and bought the kit used. The only negative is that once it's hooked up, you need to leave it until you finish planting, because it's a job. The kit we have is made by command hydraulics. They are no help either. You'll have to figure it out on your own. |

southern ontario | Agee with the rest you need pto pump or a green tractor. We have 1770 16 row two fans with e sets and had to get pto pump and it's wasn't big enough waiting for bigger one to show yet this spring |

Tennessee | If you get a green tractor make sure it has the big pump. A standard 8200 pump would only be marginally better than the Ford.
I would hook both vacuum fans and the vrd motors to the pto pump.

Is the priority 1-4-2-3 on non mega flow ready tractors? We looked in to making ours mega flow. Holy $$. About $8000 for a non mega flow ready tractor. Adding power beyond was like $3000 |

Northeast Indiana | We got our aux hyd unit used for a little over 3000 then another 400 to 500 in hyd lines to fit our setup. 150 bucks for coupler from pump to pto and made mounts ourselves. Like this better then heating up tractor hyd running motors. Less wear and tear on tractor, hopefully
Ours is a mega flow ready tractor and it was still cheaper going this route. |

Wood lake,mn | We used to run a 8770 on a 1790 planter and got along fine. Regular hyd on 8770. Planted was set up like yours. Try slowing down your hyd flow on all the remotes to just give them enough oil to work like supposed to. |
