Well it's time to put in my 2 cents, and if any dealers with better information and specific knowledge will correct me thats great, as it will clear up some of the other misinformation and incorrect suppositions.
Daedong makes ALL Kioti components in S.Korea and tractors are assembled here. That answers the original question.
Bobcat is buying Kioti's from Daedong with modifications to their specs. (Ever wonder why a company like Bobcat would contract with a "scab" outfit like Kioti, maybe because of quality?) More on that later.
Cub Cadet bought from several mfg's including Yanmar, before the deal with Yanmar/CC/MTD was inked. Now they're all Yanmars.
Compact JD's were all Yanmars until recently when they split/divorced. JD built a factory in China, so I guess they'll all be China tractors now not even Japanese!
Ford,NH and Case were buying from Mitsubishi, Sato, and I can't remember who all, then there's MF and Allis/Agco(there's that orange again), ditto previous.
Mahindra makes some of there own compact components and buys engines and components and sometimes complete tractors like ditto above.
Personally when I was in the market I researched for 2 yrs before buying my Kioti almost by accident. I had narrowed my choice down to the 20hp Kioti or Mahindra because of their weight and lifting capacitites were better than anything else in the class. Both had excellent reps, but dealers were sparse, then Galen LaWall in Batavia NY picked up the Mahindra, just about the time I was ready to buy he took a CK20Hst with subframe BH with only 27 hrs, just what I wanted. I was a little skeptical at first , must be something wrong. Galen offered my the previous owners phone number unsolicited, so I called the guy he loved the CK20 but needed a bigger machine and couldn't afford 2 new tractors. So 800hrs later and lots of dirt moved later wouldn't change a thing. Oh and the only repairs other than the infamous loader repair were caused by me, not the tractors fault.
As to Ford /NH and Bobcat, I was buying filters etc from a local Bobcat/NH dealer and got talking to the parts mgr. He said they were VERY happy with BC/Kioti , the repair and warranty rates were lower than any other brand he knew about and didn't give him headaches trying to figure out who made what on that model NH that year!!
Ok I'm done , have at it kids!
