There are a couple different ways to hook up a TNT kit from CCI or you can make your own, but I'd still strongly recommend the CCI hydraulic cylinders with piloted check valves.
If you have "power beyond" on your loader valve, and if you use the CCI TNT kit with 4 way valve, then you can run 2 lines off your loader valve's power beyond port to the 4 way valve. The CCI 4 way is a nice valve because it is joystick controlled and works like a loader control to control all the functions.
-OR-
You can add 1 rear remote (2 outlets) and power the 4 way valve from that 1 remote. This gives you 1 lever + the 4 way joystick. If the lever locks in place, then you only have to slide it into an active position and you have full joysick control. If the lever auto returns to center, then you have a 2 hand operation where you hold the lever in place and then work the joystick.
-OR-
You can add 2 rear remotes (4 outlets) and eliminate the need for the 4 way valve completely. You would then have 2 levers, 1 to control the top link, the other controls the side link.
Option #3 is probably the cleanest setup in terms of looks. Option #1 gives you the advantage of easy operation with 1 joystick but you have to find a location and method to mount it. Options #2 & #3 let you use the rear remotes for other things if you ever have to power hydraulic implements such as a log splitter. Option #2 makes the system portable and lets you mount it on any tractor with a remote.
DISCLAIMER : we have people on TBN who know much more about hydraulics than I will ever know, but I know enough to get you through the basics.
