Think of trading in my JD 4300 toward a ck3510 or 4010. My question is what would I need installed hydraulics to operate a loader mounted grapple or snowplow. My jd has a 3rd valve.
What you *need* will depend on how you want it to operate.
There are actually 3 options
Option1 & the cheapest being a set of long hoses to one of the Rear Remotes, the down side is it won't be the easiest to operate since you have to mive between the loader conrtrol and the Rear SCV control.
Option 2 and mid range on expense is a Diverter Valve.
Think of this as an Electronically controlled A/B switch. It get's installed between the loader valve & the cylinders the valve controls (typically the Curl/Dump function). Then you have a single On/Off push button on the loader knob. When the button is Off - the curl/dump function works like normal. When the button is On (Pressed) & the loader control is moved in the Curl/Dump directions, the diverter sends fluid to (in this case) the grapple lid to open and close instead.
A PRO to this is that you have proportional control of the operation and are able to gently feather the controls.
The CON is that you have to pick Curl/Dump OR Open/Close, which means at some point your desired set of actions will require you to press the button, move the stick one way, center the stick, let off the button, move the stick the other way. Folks who have this set-up say that with a little time it becomes second nature and they like having the ability to feather the 3rd function
Option 3 is the most expensive and that is a "true" 3rd function.
In this case you have 2 buttons on the loader control that operate a separate solenoid valve which controls the Open & Close function of the grapple independently of the loader valve.
The catch & the reason I put True in quotes, is that it will only be able to supply the fluid from system that is NOT already being used by the loader valve. What that means in English is that even though it's a separate valve / function it will most likely not operate in tandem with either the Lift/Lower or Dump/Curl functions in operation (unless you are feathering them very very lightly).
The PRO here is a slightly simpler control set to learn and the ability to come close to getting true 3rd function operation **
The CON is these valves are simple On/Off valves so you have no ability to feather other than just making quick "blips" on the control button.
I've run our grapple like that for quite some time and honestly I haven't seen a single issue with not having the ability to feather, but I don't grapple eggs and glass either.
** Michigan Iron & Equipment has recently released a new 3rd function kit that is plumbed / ported in such a fashion as to allow true 3rd function operation. They offer both a simple Off/On like the other 3rd function solenoid version (but with true independent operation) or a Proportional Version that allows feathering like a Diverter set-up.

The PRO (obviously) is these allow true independent operation of the 3rd function regardless of what the loader valve is doing.
The CON is cost. As of right now it's $1195 for On/Of and $1495 for Proportional
There are several great kits on the market from forums supporters like MIE and EverythingAttachments, MtnViewRanch (
Fit Rite Hydraulics - fitritehydraulics.com) and Kens Bolt On Hooks (
Ken's Bolt on Grab Hooks <<Hydraulics>>) to name a few.
You also have the option to build your own. Several folks here (myself included) have done that. I have attached the write-up I did for our CK35 if you're interested.
Regardless of what you pick, there are lots of folks here that can help you out if you get stuck along the way.
