The laser leveller involves the use of laser (transmitter) that emits a rapidly rotating beam parallel to the required field plane, which is picked up by a sensor (receiving unit) fitted to a tractor towards the scraper unit. The signal received is converted into cut and fill level adjustment and the corresponding changes in the scraper level are carried out automatically by a hydraulic control system. The scraper guidance is fully automatic; the elements of operator error are removed allowing consistently accurate land levelling. The setup consists of two units. The transmitter is a laser, which is mounted on a high platform. It rapidly rotates, sends the laser light in a circle like a lighthouse does, except that the light is a laser, so it remains in a very narrow beam. A laser controlled land levelling system consists of five major components: Drag bucket Laser transmitter Laser receiver Control box, and Hydraulic system   Benefits   Laser controlled precision land levelling helps in Improving crop establishment. Improving uniformity of crop maturity. Increasing approximately 3 to 5% of cultivable land area. Increasing water-application efficiency potential up to 50%. Increasing cropping intensity up to 40%. Increasing yield of crops (wheat 15%, sugarcane 42%, rice 61% and cotton 66%). Controlling the emergence of salt affected patches in the soil. Saving irrigation water by approximately 35-45%. Reducing weed problems and improving weed control efficiency   Limitations of laser levelling –   High cost of the equipment/laser instrument. Need for skilled operator to set/adjust laser settings and operate the tractor. Less suitable for uneven and undulated fields
