d17 let me down

well i bought a hoelscher 1000 accumulator and i was planning on running it with the d17 yesterday and plumed hydraulic and nothing but disaster all day. we thought valves was stuck and i moved about everything i could. well i learned about open and closed center systems and we move some hoses and settings  no change go and get a deere and things works perfect lol

Well, you tried. Sure would have been a lot cheaper to run the D17.

Yup.  D-17 needs to be hooked up to implements of that time period.  You take your chances on a 50 year old tractor on an implement produced 5 years ago.  If it works great, but don't count on it.

A friend of my Dad bought a new Deere planter this year and could not make it work correctly on his New Holland tractor that is only a few years old. Ended up trading the New Holland for a new Deere tractor. So it isn't only the old tractors that won't work with newer equipment. Seems the Deere planter isn't very compatible with New Holland.

A few years back, my neighbor bought a 12 row JD planter. Hooked it to his almost new JD tractor and it wouldn't run the vacuum pump. JD mechanic couldn't make it work so he had to use a different tractor to plant with.
 Next year he orders a new JD and specifies, he wants 3 hydraulic outlets and want it to run the planter.
 They called to tell him his new tractor was in and guess what, only 2 hydr outlets. After they added the 3rd, they still had to mess around a couple times to get it to work right

Looks like you did a great job stacking those up. I have trouble lining up square enough to get them stacked too high.
I would think the serries 4 hydraulics would have plenty of flow for the accumulator.   I would probably check the pressure release to make sure your system is developing good pressure. The other thought that comes to mind is does the valve kick off when the accumulator comes to the end of stroke some valves will pop back to center. I don't know how the serries 4 hydraulics are actually setup as I have ever used one.
What I did on my tractor was setup a inline pair of disconnects that allow me to go from the pump to my out to my accumulator them back to my normal hydraulic valves.   I did this with a ball valve and two T's on either side with disconnects. The idea is if the accumulator is not hooked up the ball valve is open and oil flows through the ball valve to the input of the hydraulic spool valves. If I have the accumulator hooked to the two quick connects on either side of the ball valve I close the ball valve and fluid has to flow through the accumulator.   I also have a pressure release valve before the ball valve incase I forget to open the valve when I unhook the accumulator it won't dead head the pump. It is a little bit of work to set it up but I love the full flow without having to trig open a spool valve for the accumulator or also for a wood splitter or anything you might want to use with remote valves where you are not sitting in the tractor running it.
My guess is your pressure release is set too low and your not getting the pressure or your spool valve doesn't stay on and pops off when the accumulator come to the end of stroke.
Nice work getting the 800 bales our grass is only about 6 inches long now. We have a short season here only 100 days.
Oh I just thought. On my accumulator I added a second flow control to run the other cycle. That allows me to set the speed of both the flipper and the dump independent of each other. That made setting it up alot easier. The dealer told me oh you have to play with the flow on the tractor.   I didn't want to do that so I added a second flow control under the accumulator.   That might help as well.
