As Brain55 indicated, the hydraulic top and side links remove just the same as you existing links - just heavier. Do you already have rear valves? I looked at Kubota's set and decided that I could do better for the same or less money. Not quite done yet but here is the setup as it presently exists.
I hope to have the plumbing done this week.
The front two valves are operated by a joystick and will connect to the top-n-tilt. The third valve is a standard spring-centered, 4-way. The fourth valve is a reversable motor valve with a detented spool. The handles on the third and fourth valves will be replaced with vertical, booted handles to get them out of the way and to keep out the elements.
My links are coming from Carter and Carter.
Good luck with your system.
