South Korea's two biggest agricultural machinery companies, Daedong and TYM, squared off directly at the 2026 Korea International Agricultural Machinery and Materials Exhibition (KIMSTAR), held Nov. 4-7 at Daegu EXCO, putting self-driving technology at the forefront. TYM, marking its 75th anniversary this year, unveiled a self-driving concept tractor for the first time, while Daedong emphasized its technological lead with AI autonomous-work tractors already in the commercialization phase. Daedong set up its largest-ever exhibition booth at 810 square meters (about 245 pyeong) and placed the HX1400-AI, a vision AI-based Level 4 autonomous-work tractor, on display. Launched in April, the model also served as an interactive space where visitors could operate the steering wheel and pedals themselves to perform a virtual farming task, then compare their own work path and results with those of the AI tractor. A transport demonstration of the RT100 agricultural robot and a mowing module mounted on the robot were also exhibited. TYM's T130 Level 3 self-driving concept tractor, shown for the first time at this event, automatically handles straight-line driving and turning and detects obstacles. It also features an "X-turn" function that changes direction with the work path in mind. The company said the model demonstrates the direction in which self-driving technology will be applied.
