I bought a case ih 9150 this spring, and after some repairs I was ready to use it. hooked it up to jd 935 30' disc. it has the fancy lever shut off hyd valves, pioneer I believe, could not get it to lift the disc off the ground. it has 4 sets of these valves, and I tried all combinations of valves and switching hoses around, but no luck.finally backed another tractor over there with reagular pioneer couplers and hooked it up and that worked and raised it up. what is the problem here? I couldn't believe that all 4 sets of couplers were bad at the same time.
 
Couplers aren"t bad- just different? Does the tractor have ISO couplers? They look similar to a standard Pioneer, but have a longer shank. My 1983 JD 4450 MFWD has them, all the earlier JDs I have/had, used the JD coupler. AC and my Case 2470 and others used Pioneer, IH had their own style, as did JD. If they"re not right, they simply don"t couple. It took the industry 40 years to standardize couplers.....so we deal with adapters, extra source of leaks, RATS! the adapters are in the other tool box!, etc.
 
Are you sure you have the return hooked to the pressure on the same valve. Some times the mate is above and sometimes it is aside.
 
Perfect example! I was used to JD for decades- side by side matched couplers. Got the 2470 Case 4WD in "85......hooked up the chopper.....got nothing but hoses flipping one way or another, doing nothing. Figured out they were up and down combo. Had several remotes...maybe 4?, but different layout.
 

You need different tips. Your males aren't reaching far enough into your females to open the check valves. I had the same problem once.
 
You hook them up and then turn the lever to open the fittings. The lever type are really nice to use as you do not have to worry about there being pressure on the lines/tips. You may have had the levers in the wrong position. You can usually feel the lever open the tips.

Also are you sure you have hydraulic pressure to the remotes??? You said this tractor needed some repairs. I would check and see if you have pressure at the SCV couplers.

Your disk and Tractor are both new enough that the tips should be the same. Some of the earlier tractors had to have the square tip on the Pioneer fitting. They would not work with the ball tip that most Pioneer tips have.

I would suspect that you have something going on with the tractor in front of the couplers. The couplers are pretty simple. I am not familiar with the SCV controls on that model of tractor. Could they be set to supper low flow or even off???

I had this happen a few times when JD switched SCV controls on the 7000 and 6000 tractors. The old flow control valve only turned about 270 degrees in total. The newer ones can turn 8-10 turns. You can fine tune the flow in real fine increments. So some of them got shipped with the flow turn all the way down. The new owner would turn it the 3/4 turn open and then had low flow or so little flow they thought they had zero flow. Cost me a 50 miles service call the first time I ran into it.

So maybe someone with a CIH 9150 will post on how the flow controls work on your CIH 9150. It may just be a setting that is wrong.
 
after 3 hours fiddling around, I went to farm store and bought new couplers for the tractor, problem solved. no one sells them leaver couplers anymore except agco @ $250 each, which were standard on the workhorse series. I also have them on my white 4-270 with the same pioneer hose ends, no problems. must be some difference in the leaver couplers between brands? my new 8000 series couplers cost $28 with 2 extra hose ends
 
I am glad you found your problem.

The lever style are still available. Farm and Fleet carry them. They run $130 a set. I really like the as you can hook up under pressure.
