Have a Yanmar 276 D and bucket with tooth bar. I want to add a bolt on grapple. Could someone steer me towards information on plumbing this set up?
Thanks

Does your machine already have a set of rear remotes? I just ran long flexible hoses from the rear of my NH under the floor, and out the loader arms where a grapple could be attached. I think I spent about $100 on 2 long hoses and the needed fittings. The lines just stay on the tractor but when I'm not using the grapple I disconnect them from the rear remotes so they are free to use on other implements. A third function button on the joystick would be nice but didn't really seem worth the cost to me.

If you have a basic understanding of electricity, just substitute hydraulic fluid, hoses and valves for electrons, wires and switches. Circuitry Logic is similar.
If ports A & B on your machine are not being used as shown in my earlier post then you can tap in on port A, go through a control valve, then back into port B. Just showing an example of a valve that might be used. 1 Spool 8 GPM Prince MB11B5C1 DA Valve | Directional Control Valves | Hydraulic Valves | Hydraulics | www.surpluscenter.com

Well you are lucky to have a YM276, they are one very nice tractor. A real classic. No matter what kind of loader you have on your 276 there's no doubt you can add a control for a grapple.
There's a number of ways to do that, and they all start with us needing to know what loader you have and how it is hooked up now. For that, we'll need to see some photos, so first step is for you to learn how to post some photos of the tractor, loader, hoses, and particularly some of the loader control valve that works the lift and curl of the bucket.
What we are looking for firstly is to see what you have....whether it is a factory OEM Yanmar loader and loader control valve - or some other brand of loader and control valve. That will tell us whether we can tap into the existing loader control valve to get power for a grapple - or not.
The second thing we are looking to know is .... What is the source of the loader's hydraulic power now? It could be powered from the tractor's internal hydraulic pump as Winston's attachment shows (we need a better photo there, too). Or the loader could be powered by an accessory pump driven somewhere else on the tractor. Yanmar dealers powered their loaders both ways.
First step is some photos so we can figure out what you have.

several ways to do it. I added a thumb to my yanmar without using 3rd function
Used a 3rd function valve on my Kubota

Finally got a chance to get pics of the hydraulic set up. Looks like 3 hoses from the hydraulic cylinder head. Two to the loader control valve (cv1 out and high pressure line? and cv2 return?) and one from PBY or aux Valve? Hard to make out in the service manual pics.
PBY goes to a block labeled modular control valve. Two lines from there - one to the loader control valve and another to the power steering cylinder. There's one line from the power steering cyl to a port in front of the shift knob (return?).
Finally it's a Yanmar loader model YFL 1075.
It's been a great machine. I've put a couple of hundred hours on it over the last ten years mostly plowing snow and getting firewood in. Haven't had a real problem yet. A lot of good advice from this forum.
Grateful for any info leading to my understanding of the set up and the installation of a bolt on grapple and possibly cylinders to angle a snow plow.

Your hydraulics are plumbed using the auxiliary outlets shown in post #2. I am not a hydraulic guru but do feel it is plumbed correctly. Might be expensive but I am thinking you might be better off going with a new loader control valve. Attaching an example. I know you are not going to like the price. I haven't done any shopping or comparing.
The control valve used to go to your power steering and loader valve assures you don't lose power steering when using the loader.
