...but if I'm mucking with the hydraulics it makes sense to me to add additional capability for 3PH attachments at the same time.
Ted ...it made sense to me, too. :thumbsup: It was not much more $$$ for the 3 - If I were to do it again, a fourth valve is $40... and only sticks out an 1" more. I would plug it until I needed it.
I like where you mounted the additional spool (I have an
L3400) & most of it all makes sense though I don't have hydraulic experience beyond the automotive kind.
I had NO hydraulic experience... Take time to read many of the threads on TBN. ...and above all asked before you buy!!!
You used a 3 spool control; one for the grapple, two for rear-remotes?
...I'm in the process of buying the Top and Till hydraulics for the 3ph... but the part I like, I can route the lines to either the front or back very easily (if I were to do it again, I would use 96" instead of 84" but as it is now, I'll add extra hose on the TnT)
What are the needle valves for?
...to be able to slow down the hydraulic flow. The same can be done by feathering the valve... but this is idiot proof... so I got it for the wife

.
I was wondering what you have hooked up, in one of the pics it looks as though there is only one circuit unused?
...Actually until I place my order, two valves do nothing :confused2: The valve that you see "un-used" will actually be the grapple. That is so when I drop the FEL, the grapple will disconnect right there. It was also planned that I can hook a log splitter up to it... (thus, nice to have 4 valves).
Oh, BTW... the bucket grapple is very nice, drive up to a pile of brush and let the tractor pick it up...
