    Posted: 30 Jul 2015 at 9:24pm
I'm working with a person who want to have 2 - 2 way hydraulics on the front of his 720/620/616.  I know that the front has room for 4 outlets and the bracket on the side of the engine is made for 4 lines. My question is where would another control lever and valve go or was it a 2 valve/lever system with one valve controlling one set of front outlets plus the back ram and the other lever controlling the second set of front valves.  I have never seen the set up so I'm guessing this is how it is done.

You need the lines from a single bank valve to add to the dual bank system. Did that on my 720.

the second lever would go right next to the 3pt/1st remote system.

I've been reading this thread over and over.  Looking at the picture.  I still don't get how it works.

So when you have 4 ports out the front does the second set of ports run off the 3pt lever?  Or can you put 3 levers across the left side?
