7530 and pronto 3dc first impressions/problems

[babibux]

Hello everyone.
I have done my first day of seeding with this setup, used to seed with amazone KE 303 + D9.

I have some minor problems and bugs, maybe someone of you will know better than I.
When I am raising rear hitch the fan on the seeder almost stops. Fan is on 25% flow on one spool. But when I raising the seeder with other spool then its ok, no slowing down. Im working without markers, when I enable markers I have the same problems like with rear hitch. Raising or lowering with markers will kill the fan.

So I have to raise lift arms slow with lever, not with a button, then its ok.
I dont have option to slow down flow on the three point hitch. Another thing for three point hitch, when Im raising something and the lever (in the cabin) is all the way down but rear arms are on 35% height it will need aprox. one sec to start raising. Like it has to pump it first, and all the pump capacity goes into three point cylinders.
Thats it about 7530

The only thing on pronto is pulling to the left when working depper with cultivation discs. It seems to me the second row of discs is going deeper compared to the first ones. Thats just my logic. When I raise the discs, it goes straight.
I tried to explain as best I can.

A cultivator disc drill will normally pull one way depending on the disc formation. Is there a linkage geometry bar you can alter to set the front row deeper or shallower than the rear?
As for the tractor I had similar when I used to drill with a 6930, the fan speed would drop once you used another function. Never really did find a cure apart from having the tractor revving on the hand throttle all the time which did help.
Can you set a spool to be a priority one?
Have you tried the fan in a different spool to see if it helps?
You could also turn the flow down on the others so it doesn't rob quite so much oil from the fan spool. .

I will try to use different spool. Reving it doesnt really help, it has electric scvs.

Use the blue spool for constant flow the one nearest to the centre as it gets it's oil first

 

[babibux]

Im using the blue spool. Its alright now, Im used to it, just need to raise three point hitch a litlle slower with lever. Just 15-20% up.
But I believe it will be necessary to inspect and calibrate and possibly replace some parts on hydraulic system as soon as I finish seeding.

hi i had exactly the same problems on 30 series hydraulics lift the marker to go round a pole and fan cuts out. john deere didnt want to know.

 

[babibux]

Only on marker lift it cuts out? 6 or 7 series? I guess mine would do the same then. Did you manage to solve that?
Btw my friend tells me he was seeding with 6530 premium and amazone cirrus without problems with 60l pump.
I looked at tractor data, 6030 series have "load-sensing pressure-flow compensating (PFC)" hydraulics, but for 7530 it says "closed center, pressure and flow compensated"

Try putting flow restrictors into the boot market lines. When oil can flow multiple ways it tends to go the way of least resistance.

I have a flow restrictors on the supply to the fan. The fan tends to over speed after it has slowed down as the flow control tries to increase flow to the fan when the pressure has dropped. I was regularly getting fan over speed alarms before that. Also helps prevent over speeding the fan when flow control on that spool was set much faster for a different implement.
