For what it worth, the hose made by a hydraulic shop was about $60.00. I am sure NAPA or other parts shops would be about same cost. Also most AG dealers make hoses, I have had many made at my local Deere dealer.

Well not quite, the system maintains pressure "two blocked" on both sides of all pistons. This keeps the jacks and slides in position. Without system pressure the jacks will gravitate and slides are free to move. If you disable the motor + connection and bleed off the system you'll get rid of the pressue. Don't think any valves will work though, the pump power is applied to solenoid valves also. The system pressure is well over 1000 psi, need to be careful working on oil side.

Curious. Did they have the ends?
What size and type were they?
Just wondering if I need to do this again.

I understand that the system maintains psi as you say to keep everything in place, but where do you bleed the pressure off at? Is there a bleed valve located somewhere on the system?

Yes they had everything on hand, they did not appear to be anything special. My local Deere dealer would make them for my farm machinery and they used many different kinds of ends and always had them on hand. Often they would make them while I would wait. I am sure one of our local parts stores makes them also. I think changing them would be simple enough but I would need some more room to work under to get old hoses out, the rear ones lay on top of the fuel tank on my 350ts. FR offered to provide the hose if I would wait 3 weeks for the replacement.

Never had to do it, my problems were electrical/electronic in nature. To remove any hydraulic component I would disconnect and safe end the heavy 12V supply to the pump. After that simply release a supply and return hose at any device. Shouldn't be much volume esp if you chose a high point connection (slide). At least you'll expect a short burst of oil pressure.
