Disclosed is a direction guiding and controlling device for an agricultural land leveler. The direction guiding and controlling device comprises a land leveler body (1), width detection devices (2) are arranged at the two sides of the land leveler body (1) and are connected through a moving track device (3), levelness detection modules (4) and probe components (5) are arranged at the front end, guide devices (6) are arranged at the inner sides of moving idler wheels, when the device is in operation, the guide devices and the land leveler work synchronously, relevant detected data is displayed on a display device (7), and meanwhile intelligent guiding and controlling operation is conducted according to demands for the width and levelness of flat land; a promoting device (8) is arranged, and the prompting device gives out prompting information when skewing phenomena occur in the operation process; a central control device (9) is arranged in a main control chamber, and comprehensive analysis and comparison are conducted aiming at the detected data. In the direction guiding and controlling device, the added structure is reasonable in design, real-time monitoring is effectively conducted aiming at the orientation of the machine body, and the occurrence of the skewing phenomenon is avoided; meanwhile, an intelligent manipulation mode is adopted, the stability is high, and the direction guiding and controlling device is beneficial to subsequent management of farming work.
