A continuous track self-propelled dual-rotary tiller, comprising a frame (1), a continuous track locomotion mechanism (2) arranged on a chassis of the frame (1), and a power mechanism (3) and a transmission mechanism (4) respectively arranged at two ends of the top of the frame (1). The power mechanism (3) is respectively connected to the continuous track locomotion mechanism (2) and the transmission mechanism (4). The continuous track self-propelled dual-rotary tiller also comprises two rotary tillers (5) respectively arranged at a front end and a rear end of the frame (1). The transmission mechanism (4) comprises a front transmission unit (42) and a rear transmission unit (43). The front transmission unit (42) is connected to an output end of the power mechanism (3). The rear transmission unit (43) is connected to the front transmission unit (42) or the output end of the power mechanism (3). The front transmission unit (42) and the rear transmission unit (43) are respectively in a transmission connection with a front rotary tiller (51) and a rear rotary tiller (52). The continuous track self-propelled dual-rotary tiller has a high operating efficiency and low operating costs, and is able to reasonably utilise the output efficiency of the power mechanism of the continuous track self-propelled dual-rotary tiller.Linvention concerne un motoculteur double auto-propulsé à chenille, comprenant un cadre (1), un mécanisme de locomotion à chenille (2) agencé sur un châssis du cadre (1), et un mécanisme dalimentation (3) et un mécanisme de transmission (4) respectivement agencés à deux extrémités de la partie supérieure du cadre (1). Le mécanisme dalimentation (3) est respectivement relié au mécanisme de locomotion à chenille (2) et au mécanisme de transmission (4). Le motoculteur double auto-propulsée à chenille comprend également deux motoculteurs (5) respectivement disposées à une extrémité avant et une extrémité arrière du cadre (1). Le mécanisme de transmission (4) com
