Ok, officially tired of the hoses running to the rear of my tractor. I see there are kits that you can buy, and I have read the posts on here, but would like more specific information for my tractor. Please help.

Hydraulics:
Type: open center fixed displacement
Valves: 1 or 2
Pump flow: 11.6 gpm [43.9 lpm]
Total flow: 16.9 gpm [64.0 lpm]
Steering flow: 5.3 gpm [20.1 lpm]
Where do you want to put the 3rd function, and what do you want to control?

I have a grapple that I want to control. I would also eventually like to buy a hydraulic post-hole digger.

You have a 11.6 GPM attachment flow using an open center hyd system..
Is your hyd pump external and what do you have for hyd now?
Are the supply lines metal of hose?

Ok, I am a real newbie when it comes to this stuff, so not sure on the external pump question. I am running the grapple controls off of my single rear remote. The rear remotes supply lines are metal.

Do you have a loader since you say you have a grapple ran off the rear hyd.
If you do have a loader and a two spool valve, then you can use a diverter/selector valve to switch between the loader curl circuit and the grapple.
12 VDC 13.2 GPM SAE 8 DOUBLE SELECTOR VALVE
You also need a switch, cable, and handle.

External pump means just that, the pump is on the outside of the engine, and an internal pump is built in and may not have any lines on the outside of the tractor, making it difficult to add things.
If you can get to the flow path, you can modify the hyd flow path.

Thanks for all of the replies. Much appreciated. What is the difference between what has been suggested and this Third Function 3rd Function Valve Kit New Holland Tractor Front End Loaders | eBay

That valve will work as you want.
However, that valve will provide full flow at all times unless you reduce the engine rpm, add a needle valve or a restrictor washer in one of the fittings.
How would you control the speed of the auger/grapple?
If the 3rd function valve is second valve in the series path, and the first valve is using all the hyd flow, the 3rd valve will have no fluid flow.
That is an expensive 3rd function valve.
You can gather up all the parts and do it yourself for less.
