Abstract
Korean agriculture is now in crisis. According to the 2007 agricultural economic statistics, household income increased only 39% compared to 10 years ago, but decreased by 1% compared to the previous year. The average farmer's debt rose 140% from a decade ago to 2,946,000 won, up 16% from a year earlier. At the point where rural society is moving from an aging society to a super-aged society, we can see that most people are old in rural areas and our society is now moving toward a society of cutting-edge science and technology and working hours. However, the mechanization rate of farming machines in Korea is approaching 80%, but the mechanization rate of farming machines in fields such as farming machines during the regular period is less than 50%. In particular, the importance of sowing and farming machines is increasing. The number of farming households from seven million in 1990 more than halved to three million in 2006. Experts predict that the number of people under the age of 40 has decreased from 35% in 1970 to 3.5% in 2003. At this rate, it will be under 1% in 2030. As an alternative to this crisis, we thought it was essential to develop Korean agriculture by researching and developing machines that reduce the labor force a little bit and improve the machine's time optimization and efficiency.
