Daedong announced the DH6135-A six-row combine on 19 October 2023, describing automated travel, turning and harvesting operations alongside yield-monitoring functions. The Korean manufacturer presented the machine within its then-current Level 3 agricultural automation framework.

The release explained that an operator first drove around the field perimeter to define the working area and turning space. The combine could then follow the resulting harvesting route. Daedong also described yield information displayed through its Connect application, with fields divided into selectable spatial units. This connected the physical harvesting pass with a data record that could inform later management decisions. The claimed route accuracy and uninterrupted-operation capability came from the manufacturer. The source did not establish completely unattended operation under all field and weather conditions, or demonstrate that yield maps alone produced input savings.
