Apparently Kioti engineers (and technical report writers [who are supposed to audit procedures]) haven't ever changed coolant in one of these tractors. Also seems that Kioti hasn't been interested in making it anything but difficult for many years. Anyway...
Manual shows to open up the petcock. This is nearly impossible to do as there is almost no room (but if you can endure the pain of contorting your fingers [forget about getting a tool in there!] you can do it): sounds like this isn't a unique "feature" for NXes. There's a nipple for the drain which I though would be good to use so I could route the draining coolant away from the axle (and splashing all over the place). The nipple is tucked up under the radiator support bracket (just enough) that this too is almost impossible to get a hose on: I used some curved needle-nose pliers to help cram the hose on), with about 1/2" of room to bend a tube in.
The draining-by-tube method (with radiator cap removed) turned into a very slow process. Perhaps not even a gallon drained in an hour: I always have things to entertain myself with, so no big deal other than having to periodically check that I wasn't overflowing the one-gallon jug. I gave up and put a pan underneath and have the petcock all loose, leaving this to drain whatever it could overnight.
How does one conclude that the cooling system is sufficiently drained? I've spilled some of the original coolant, so not sure exactly how much as come out.
