OK, just when I thought I had this all figured out, I actually got a chance to look at my
BX2660 and I'm lost all over again. The
BX2660 has an integrated FEL control so all of the plumbing is well hidden and tightly packaged.
The result is that there is no clear indication of which line is the power beyond circuit.
On the valve assembly there should be a PB stamped into the valve...Also this line will run from the valve assembly to the hydraulic block. On the block there is a line running out into the valve and a second one returning.. Your block may look different but here is a reference picture.
I believe that it will be far easier to extend the existing line at the rear of the tractor than trying to replace the line all the way from the front
Pictures tell alot. I'm not familier with your lay out so take some pics and post them of your "rear" line
Also, if anyone can tell me if this will interfere with the future addition of rear remotes, that would be a bonus.
