I heard someone on here say it was transmissions.
Kubota and Daedong (Kioti) have a history of being less than friendly competitors that goes back a long way, with lawsuits and out-of-court settlements involving this sort of stuff. 30 years ago, they evidently did a deal to build one model line for Asian markets, but the deal fell apart and ended in litigation.
From "RitchieWiki": "In the early 1980s the two companies collaborated to produce the 適ubota 02″ product line. Daedong provided the transmission and the steel for the body. Kubota provided everything else. After the collaboration, Kubota accused Daedong of stealing engineering secrets. The conflict culminated in 2002 when Kubota filed a lawsuit against Daedong. The lawsuit was drawn out over five years, but finally settled out of court in 2007 for undisclosed compensation."

Daedong issued the following press release in 2007:
"Kubota Corporation and Kubota Tractor Corporation, on the one hand, and Daedong Industrial Co., Ltd. and Daedong-USA, Inc., on the other hand, have settled the lawsuit that was pending between them in Federal District Court in Fresno, California.
The lawsuit alleged, among other things, that certain aspects of the appearance of Daedong。ッs Kioti tractors infringed trade dress and other rights that Kubota asserted exist in Kubota。ッs tractors. Daedong vigorously disputed these allegations.
Daedong wishes to once again inform consumers that there is no relationship between Kubota and Daedong or their respective products. Kubota and Daedong are completely separate companies, and there is no manufacturing or engineering relationship of any kind between Kubota and Daedong. Accordingly, neither company。ッs dealers are obligated to honor warranties on the other company。ッs products, and neither company authorizes its parts to be used on the other company。ッs tractors.
Other terms of the settlement are confidential."
