If you ever mow back there you will find the pin.

Here's a picture of the ones on my BH65, it's not attached to the tractor, but I threw in the pin so you can see.

The bottom one is correct. The sliding rod is held in place by gravity. My BH75 has the same setup. If you use the top hole there is nothing to hold it in place.

.... they're a real pain to get out (I think kubota painted the pin holes and reduced the clearance so its a tight fit until it wears a bit).

When I bought my tractor with BH77 hoe the delivery guy said if the pins feel too tight to adjust the stabilizers or bucket to get weight off them. When I took the hoe off for the winter they slid right out once I played with it a little. I think it's a fine line where they're easy/hard to pull. Maybe yours is the same?

I was happy to find the B3000 had longer hoses than my BX23, which did not allow you to move the tractor very far from the backhoe.

There's definitely a sweet spot for taking the pins out. In my case when I'm in that spot they get through two parts of the pin hole and bind slightly on the outer part of the hoe frame. I tap it in and out, which works well. I think its just the paint in that outer hole that binds it, the other two holes have the paint worn down a bit and slide freely. The tractor's still almost brand new and the previous owner had never had the hoe off. They probably could use a good coat of grease as well, the thumb pin has the same issue, but is much better now that I've used it a few times.

I have a B26 with the same setup. The first time I took the BH off the tractor (purchased used) had about 320 hours on it. One pin (the left one) was really hard to get out even when wiggling the BH up and down anf hotting the pin with a ball peen hammer. Not really seized in, but very tight.

I finally got it out and really lube both pins and holes. The next spring I had a hard time getting the holes to line up. Although there is a slight tapered end on the pin it still wouldn't go in without a lot of work. I took the pins off one at a time and turned the ends on a lathe so there was more of a taper. The part I turned down sticks out when installed so there wasn't any loss of strength.

My BH76 has only one such hole to place the rod that connects to the pin. I don't know about the design of any other model, but I put this rod through the hole thinking it would stay in place and it managed to fall out of the hole and then the pin begins to work its way back out.
So, I bought a replacement pin and a spare at $22.00 each (ouch). I reinstalled it, put the little rod through the keeper hole and dug 4 tree stumps before I took a break and noticed the darn pin was getting ready to fall out again. I took it back over on level ground and removed the pin. I then drilled a hole through the end of the keeper rod, reinstalled the pin and the rod, then I safety wired the rod so it cannot back out any more. I repeated this process on the other pin and no more problems. Now I have a new spare that I will never use and of course, right before I left, I found the old one in the mud.

I had my BH76 in for service last week (another story), and when I picked it up, the mechanic at the shop was trying to figure out the "why" of having what appeared to be a "retaining hole" for that sliding rod that was "above" the center of the pin. If you put the rod through that hole, the rod will vibrate out almost as soon as you start the tractor. Does anyone know what that hole is really for? Even the mechanic at the Kubota place had no idea.
