近几年来，一些发达国家不断将高新技术应用到农业机械上，使农业机械向智能化方向发展。耕作机械智能化。美国研制成功一种激光拖拉机，利用计算机系统导航装置，不仅能够准确无误地测定其所在位置及运行方向，使误差不超过25厘米，而且能够根据送入农场计算中心的电子图表，
In recent years, some developed countries have continuously applied high and new technologies to agricultural machinery to make agricultural machinery develop in an intelligent direction. Tillage machinery intelligent. The United States has successfully developed a laser tractor that uses computerized navigation systems to not only accurately determine its location and direction of travel so that the error is no more than 25 centimeters and based on electronic charts fed into a farm computing center,
