Took off all hydraulic lines,had new ones made. I had to change one leaking fitting on the pump.
My question is this. Put it all back together filled it up with fluid, jumped up in the seat and started the tractor, ran her at half throttle, pushed the lift lever forward and it came up fast. Pulled the lever back to lower the lifting arms and Nothing! Won't come down at all. Even with my weight standing on it.
Then cracked open a hose, to open the system the arms came down. Left her sit as is and came here to ask questions.. Is there just air in the system? Or perhaps something more ?
Thank you all in advance for your time.

What was the leaking fitting you changed? The original style had a flow control valve built in, that's what the jam nut and slotted screw are for.

Air in the system is not your problem here. The arms should go down. You might be having trouble from the cylinder speed regulator. You might want to try turning the adjustment screw out some. Be sure hoses are routed correctly. I am assuming you have a dual spool pump. The speed regulator connects to the upper port on the left side of the pump. The hose from the regulator goes to the base of the cylinder. The hose from the top of the cylinder goes back into the hydraulic reservoir. The lower ports on the pump go to hoses with the remote couplers. The upper right hose goes to the filter.

I had to replace the TOP left side 90 swivel fitting the one with the spring and ball. It is the one for the remote.

I don't know the exact setup - but a spring and ball sounds like a check valve somewhere. If it is in the right place lack there of may be your problem.

Where do I find that adjuster? If it is a screw with a lock nut set up like I have seen in a photo from the operators manual I do not have anything like that on any of the 4 swivel 90* fittings. 2 on each side of the hyd. housing. The fitting I changed out is the TOP one to the drivers left side.
If it was yours, what would your plan be for the morning? Where do I look? Thanks or all your responses and for putting up with my rookie questions.

CNT that cylinder speed adjuster does not appear on my new tractor. I really do not need the hitch to work for anything I plan to do with this tractor, Is this speed adjuster necessary to the operation of my hitch? As I said before it went up just doesnt come back down.. Thank you.

no it is not required to work a lot of them have been changed out over the years for a std swivel, are you sure you did not cross hook a line when reassembling? just a thought, maybe post us a pic and tell us the step/repairs you made maybe we can figuare out what happened cnt

can't quite see the LH connections but looks to be hooked up right, next question the fitting you changed was it the bottom LH that is hooked to the cylinder? and if so are you sure you have the spring/ball check installed correctly? here is another scan from the SM cnt

I changed out the TOP LH fitting from a scraped DC. Going to drain it and remove the Bottom left fitting in the morning to check spring and ball inside. Has to be the whole problem I believe. The ball is not sealing off the lift pressure. Good enough place to start.
