I'm planning to add a TNT to my 790. I was able to get my hands on a BM18005 Power Beyond kit, so this is what I'm working with. Also If I can ever find a #7 backhoe I'll be set for that.
As far as the spool valve, I'll be using one with the Power Beyond feature. The spool valve will be fed from the tractor PB "To Valve" coupler, the PB port on the valve will go to the "From Remote Valve" coupler and the spool valve output port will be returned to the case / tank.
Does anyone have a clue as to where I can tie in the tank return from the valve output to this tractor? I'm not seeing a spot to tie into. Here is a pic of what I'm trying to do.
