( Unless I am wrong or confused, which is very likely, I would prefer independent operation. What likely scenarios would warrant the diverter in preference to the DCV? )

You are not wrong or confused.

However, unless I am missing something here, having a separate control lever means 2 handed operation to get all 3 functions to work simultaneously. Whereas a diverter on the curl circuit (or lift circuit) with a pushbutton is only one handed operation.

I'd vote diverter on one of the loader circuits. It's probably cheaper $$$ wise and most likely easier to use.

"However, unless I am missing something here, having a separate control lever means 2 handed operation"

 I wanted to add the solenoid operated directional control valve(DCV) to control the grapple.

Now I am a bit confused about the diverter versus the DCV.

If I understand correctly, and please feel free to correct me if I am off again, the diverter just switches fluid flow from the curl circuit to the grapple circuit.

The diverters operation is still dependent on manual input control from the 2-spool prince valve, (ie: I would press and hold a switch then move the load lever left or right to open and close the grapple.

The solenoid operated DCV would be an independent operation and could be operated simutaniously while lifting or curling. (ie: Toggle the switch to open and close the grapple irregardless of any other loader valve action.)


Did I confuse you or am I still under a misunderstanding on these electronic operated valves?

hbarski,
The way Mad suggests will work fine, except you will sacrifice one of the loader functions when you go to the grapple. You would have to operate the function on the loader and then divert it to the grapple. You need to install a DCV in a circuit not associated with the FEL to obtain independent operation of the grapple. This will allow all 3 functions at one time.

In order to eliminate the "2 handed" operation, you will need the setup from WR Long that has the pushbutton on the handle with the electric solenoid that will allow both loader functions and the grapple to work simultaneously. Nelson from WR Long posts here with screen name nvlong4n1 and said that their system DOES allow what you want. Call them and ask for him or send him a PM. He can explain it better than I can.

hbarski,
There are several companies that sell the kit that Mad is refering to. You can cut the price in half by buying the valve and the handle seperately. Nortern Tool, among many others, has the valves and the handles are readily available through Otto or Sure Grip, to mention a few. Its all about where you get the hydraulic supply from to make it function the way you want. I have been down this road before and I am currently doing this same job on my new 4720. /forums/images/graemlins/cool.gif

Great, it's always better to have two paths that can be followed. You guys don't know how much I appreciate your advice.

Sorry for not being able to grasp everything quicker, seems to happen more often the older I get. Someone once told me that it is because we try to retain too much information, when we should be practicing load shedding.
