A direct current rotary cultivator includes a frame, a driving device supported by the frame, a cultivating device connected with the driving device via transmission devices (6, 7), and a control device electrically connected with the driving device and transmission devices (6, 7). Wherein, the frame includes a body (1), drag rods (2) and an armrest unit (3). The driving device has a DC motor (4) and a battery pack (5). The transmission devices (6, 7) include a first transmission device (6) and a second transmission device (7), and the transmission devices are connected with the cultivating device by a transmission shaft (8) connected with the second transmission device (7). The cultivating device has a knife rest unit (9) and a rotary cultivating knife unit (16) matched with the knife rest unit (9). The battery pack (5) is placed between the axle line direction of the knife rest unit (9) and that of the armrest unit (3). The direct current rotary cultivator in the present application is small in volume, easy and safe to operate, and has high efficiency and prolonged service life. In addition, the cultivator provides uniform cultivated soil particle and has self-protecting and pre-warning functions.Bineuse rotative à courant continu comprenant une armature, un dispositif dentraînement porté par larmature, un dispositif de travail du sol relié au dispositif dentraînement via des dispositifs (6, 7) de transmission, et un dispositif de commande relié électriquement au dispositif dentraînement et aux dispositifs (6, 7) de transmission.
