John Deere 2350 tractor under powered PTO need info on hydraulics on this

[jgns1]

I think you and I both know how the loader should be connected and are correct not to assume anything.

From the pictures in Post #11

Picture 3 shows nothing on the PTO shaft
Picture 5 shows the plate you change to allow float has not been changed, so I do not think the valve is in float.
Picture 2 & 5 shows a stick being used to hold the valve lever forward. I assume they put the lever to the first dent and it was kicking out (as it should)
Picture 6 shows the metering lever (rabbit/turtle) for the SCV at the bottom of the valve. It looks to be all the way to fast (rabbit)

As further to buickanddeere post, pictures 1 and 2 show the hose connections from the tractor to the splitter. My friend, Greg, marked the one hose with the orange marker ribbon from the right side and also marked on the splitter with the same...if that's any help to you. And by the way, thanks to each and everyone of you for all your help...most of what you are saying is over my head, but Greg will know.
There is nothing connected to the PTO as mentioned. The splitter is coupled to that part to the right of the fill cap...which is feed from the part shown in picture 5, and that's feed from the part shown in the attachments (not sure why they loaded like that) with the hoses that go to the loader and backend. I am trying to learn, thanks.

I noticed when I reviewed the photos that I had made an "incorrect statement" that I want to correct. The hyd oil check dipstick is in this photo you posted. It has the "red knob". I forgot later model tractors have the dipstick relocated from where earlier models were located.

Thanks Tx Jim, much appreciated. The hydraulic level on the dip stick is a the higher side of the two marks (as measured yesterday).

The hoses shown in that picture are to the loader and it (loader) works properly.

I'm iffy on the works properly. As a kid the 2020 Father owned had the loader joystick supplied from the SCV and return was just dumped back into the transmission sump. We thought it "works properly".
Unless actually verified the return oil may have been just routed to a removable plug on the side of the transmission case, lots have been.
We were pleasantly astounded at the loader's improved operation and reduction in hydraulic noise when loader supply oil was T'd in direct from the high pressure line prior to the SCV . The huge win was returning the loader oil to a ported transmission filter cover.

Just checked the specs on a 2350's front pump capacity. They were either 13gpm or optioned with 23gpm.

I'm trying to determine what the purpose is of the hose I circled in red. The parts schematic shows no such hose. Regen valve hoses are totally different from photo.

I didn't know a 2.4 IN3 pump could pump 23 GPM.

That is the correct way to plumb the loader ( I figured you knew)

I'll bet 99% got the small pump

That hose is for a relief valve return to sump. You will find the relief valve on the inside of the right loader mast. The tractor end enters the transmission case at a fitting on the right side forward of your SCV. I'll bet you have mechanical self leveling loader. If your bucket is completely dumped or curled, raising or lower the boom would cause binding, the leveling feature trying to keep the bucket level.

For the 2030 they rate the pumps at 2000rpm, maybe a higher rpm for the 2350?

2030 pump ratings small 9.5gpm, large 18.5gpm @ 2000rpm

I'll 2nd the 99% on smaller hyd pump. Thanks for explanation on extra hose. I guess I've never been around the self leveling bucket setup.
