Pioneer 9500-4 Lever Coupler Kit for rear remote...anyone use one?

[Andy4600]

I need to replace one of my tractor rear remote break away couplings due to excess leakage. I was looking at the pioneer 9500-4 Hydraulic Break-Away Coupling Kit? Anyone use one? Are they easy to use? What are the levers for? Are they ball valves for isolation?

Here is what it looks like:

Thanks

Someone correct me if I'm wrong as I've never used this style but I believe that you hook up your hoses to this style outlet and then move the levers 90 degrees so that the ball on the end of the hose is released so that hydraulic oil can flow.
