I'm going to get a grapple for my Branson 3725 and will probably make the 3rd function setup myself. It's looking like the loader's torque tube may be the best bet for locating the solenoid valve. The other possible locations are under oil filters or block access to the fuel filter and engine dipstick. The disadvantages that I can see are that it's more likely to get damaged, and I have to run long hoses out to it and those will carry pressure all the time as they're P and T lines. The valve would be in line between the dealer installed rear aux valve and the factory rear aux valves whose T line goes to the 3pt. The 3725 puts out 10.3 GPM. The charts I've looked at would indicate 1/2" hose for 10gpm. But the dealer installed 3rd rear valve has 3/8 between it and the loader valve. Should I use 1/2" to my 3rd function valve? Should I replace the dealer installed lines with 1/2"?
I realize that putting the valve on the torque tube puts it out in harms way, I will probably make a guard to keep branches from poking it.
The P and T lines to the 3rd function valve will have couplers roughly where the loader valve couplers are for removing the loader. I will make them so that they can be connected together to bypass the 3rd function. I'm a little worried that I or someone else (future owner) would disconnect the loader and forget to connect the bypass. Which would make the system deadhead. Does deadheadding for a few minutes until you figure out what's wrong hurt anything? If so are there connectors that would automatically make that bypass when disconnected?
One more dumb question. There's two kinds of solenoid valves I see- one central box for the electric connections like this:
D 3 HYDRAULIC VALVE TANDEM CENTER 12 volt DC
or two separate boxes like this:
D 3 HYDRAULIC VALVE TANDEM CENTER 12 volt DC
What's the difference? Is there anything in those boxes?
BTW thanks to guys like N2Dfire and aerojunkie who have posted their home brew third function process and everyone who helped them out.
