Got a B21 with existing 4 in 1 wr long bucket and control valve. Just got a box blade/scraper and wondering how I would hook up the valve and what kind to use. I doubt I can find a kit all made up already.

You would need some type of rear remotes. Check out Summit Hydraulics. You might be able to contact them and have them put together the parts you would need. I don't get anything for this but I watch a Youtube Channel that talks about tractors. If you use the coupon code "GWT" you can get 5% off.

Hope this helps.

Here’s how I did it for my M4700. (The video shows an L-model Kubota but it fits any with a Kubtoa FEL). $500. Takes almost 25 minutes to install.

Daisy chain a single spool valve off the power beyond on your loader and put a couple female quick connects on the work ports. Thats your new remote valve for under $200. The top link, hoses, and male tips extra.

What about tapping into the lines to the backhoe? Either with T fittings with two more couplers or by plugging into the quick couplers already there?

After attempting to educate myself a bit more, I found there were factory items for the B21.

Kubota numbers are B8032 for the top n tilt bits and B8042 for the 3rd function stuff. Anyone have new or used?
Or have diagrams, etc, showing how factory did it with those kits?

While the kit mentioned looks interesting, I think I want a couple spool valves for finer control of the box. What do I know?

Correct me if wrong, but I think I can remove the line going to the existing extra function block (from power beyond?) and input it to the spool valve and use a PB adapter in it and go from there to the existing extra function block. Rely on that for the return to tank, or would I have to find that line and T into it?
