Thank you for your patience in providing so much information, but for a novice who is in contact with hydraulics for the first time, these terms are too professional. I have no idea at all. OK, I have now checked the approximate appearance of the product corresponding to each digital term, and plan to use the most primitive method, remove the Kubota hose that needs to be replaced, and take my valve body to the store to compare them one by one.

What I need to do is,
Remove the green hose from the loader valve and connect it to the valve through a suitable adapter,
Buy another hose to connect the valve and the loader green interface,
The last hose connects the T of the valve and the T port of the block. Since there is already a hose for the loader valve on the T port, a suitable tee is needed
Good plan.

The documentation on the new valve should tell you port types and sizes. Given your global location my first guess would be BSPP.

In North America Kubota hoses are typically JIC swivels but given your spot on the globe yours may well be BSPP.

Whatever the thread type you will probably want something like this BSPP to BSPP male union for the hose connections to the new valve.

I dont know the details of the chute rotation motor but your hydraulic flow is probably more than needed and you are likely to find the chute rotates too fast.

OK, I'll consult the manufacturer. thanks Dan

@TheOldHokie
Would a flow restriction work or not to slow down the rotation speed of the chute?

Yes - those kinda of designs often have simple orifice plates in the axtuator ports to slow the cylinder down. Angling cylinders on truck snow plows are an example.

Ask a basic question, this kind of hydraulic motor that is not in continuous operation can be controlled with ordinary valves? No advanced valves (such as: constant flow or other) are needed

Nothing special needed. You are only going to run it for the length of time it takes to swing the chute.

Putting the 3rd function ahead of the loader is different than the way its done here but more a matter of preference than function. With loader first dump/curl will block operation of the grapple jaws so some might think putting the grapple first is actually better.

You seem to have it figured out. Just make sure the backhoe is always last. We did have a case recently where a dealership installed a Landpride 3rd function after the backhoe and they replaced/repaired the backhoe valve three times before it was finally identified and corrected!!!

Four spools is a lot of plumbing hanging off the back of an L02 :D Post a picture or two of the finished project (y)

I'm here to hand in my homework.
This is my first time to use a hydraulic system. I was very careful and finally completed the hydraulic modification before the heavy snow came. The local hydraulic supermarket has all the accessories. The salesperson thought I was a novice and suggested that I buy a lot of them to study and allow most of them to be returned in the end.

Since my coupler is directly installed on the valve body, the 1/2 coupler is too large, so I can only use 3/8. The 3/8 pipe is also easier to bend, but the longest pipe in the hydraulic store is 8 feet. I need 9 feet, so I can only pay double the cost to customize one. In order to save costs, I temporarily installed 2 pairs of couplers and will add more if needed in the future.

Thanks to DAN and other friends for their great support
