Shin, Seung-Yeoub,Kang, Chang Ho,Yu, Seok Cheol,Kim, Byounggap,Kim, Yu-Yong,Kim, Jin Oh Korean Society for Agricultural Machinery 2014 바이오시스템공학 Vol.39 No.4

Purpose: This study was conducted to serve as a basis for strengthening policy support and R&D to improve the domestic and international competitiveness of domestic agricultural machinery. Levels of satisfaction among farmers and service engineers were analyzed regarding the current quality of agricultural machinery and the primary consumers' propensity for replacement purchases. Methods: A survey was carried out targeting farmers in over 150 townships and 300 villages in South Korea who collectively used 711 tractors, 286 rice transplanters, and 221 combine harvesters. Furthermore, agricultural machinery service engineers from 20 different after-services were surveyed regarding the quality of main components in domestic agricultural machinery versus those in imported agricultural machinery. Results: The farmers' overall quality satisfaction ratings for tractors, rice transplanters, and combine harvesters ranged from 57.1% to 62.6% in consideration of operating performance, failure rate, and durability. Compared with imports, satisfaction ratings for domestic agricultural machinery were 19.1%p to 38.1%p lower for quality. Regarding engines, transmissions, hydraulics, planters, reapers, threshers, and electrical components, only 5.3% to 25.0% of service engineers indicated that domestic agricultural machinery was higher in quality compared with imports. By contrast, 33.3% to 78.9% of those surveyed indicated that domestic components were lower in quality compared with imports. Intent to purchase replacement agricultural machinery at the end of their respective products' lifecycles was indicated that they planned to purchase imported tractors, rice transplanters, and combine harvesters comprised 25.2%, 46.9%, and 43.9%, respectively. This clearly shows that a very high percentage of farmers were satisfied, particularly for transplanters and combine harvesters. Conclusions: The level of desire for purchasing imported agricultural machinery was very high among those who expressed intent to purchase replacement machinery. Therefore, strong policy support and R&D for domestic agricultural machinery is critical for improving competitiveness on the domestic and foreign markets.

Purpose: This study was conducted to develop a web-based business management system to ensure the efficient operation and transparent management of government-subsidized agricultural machinery rental businesses. Methods: An MS_SQL2000 database management system (DBMS) solution was utilized in the system for high system compatibility and integrated management. This system was targeted to be compatible with Internet Explorer 6.0 or later and to ensure security and seamless web operations. The system administrator is able to manage a fleet of agricultural machinery, including various inventory codes, release and return, fleet registry, and business performance. Users (farmers) may search the database of rental machinery and reserve them. Results: With respect to rental reservations, the system administrator can manage the fleet by setting the rental status to Approved, Released, or Returned. Through the web, the administrator can also create a database that includes machinery specifications, features, and rental rates. In addition, business performance data can be analyzed using a diverse array of tools to streamline the rental business. Without having to go to the rental office, users can save time and money by searching for and renting agricultural machinery through the information available on the website, including availability, specifications, and rental fees. After deploying the system, the time required to analyze monthly performance and create reports was dramatically reduced from 20 days per person to one day per person. Conclusions: Since 2014, AMRB has been installed and is operating in agricultural machinery rental businesses in 31 cities and counties in South Korea. This study recommends continued expansion and dissemination of AMRB for the systematic and efficient management of agricultural machinery rental businesses.

Criteria for Determining Working Area and Operating Cost for Long-Term Lease of Agricultural Machinery

Shin, Seung Yeoub,Kang, Chang Ho,Yu, Seok Cheol,Kim, Yu Yong,Noh, Jae Seung Korean Society for Agricultural Machinery 2015 바이오시스템공학 Vol.40 No.3

Purpose: This research suggests a method of establishing criteria for working area and operating cost for a long-term lease of agricultural machinery. Methods: Eight crops were selected-three food crops and five open-field vegetables-and agricultural machines used for sowing, transplanting, and cultivation in dry-field farming were analyzed. Results: The break-even acreage for agricultural machinery under a long-term lease was found to differ by agricultural machine, ranging from 1.0 to 5.8 ha. In terms of arable land area, the break-even acreages for harvesting machinery and transplanters were 15.6 to 26.1 ha and 6.1 to 8.6 ha, respectively. The working area lessees should secure was divided into two cases: (1) 2.0 to 11.6 ha when leasing individual agricultural machines (sowing and transplanting) for a long-term period, and (2) more than 10 ha when farmers who cultivate beans, potatoes, garlic, onions, and so on lease sowing and transplanting machines as a set. When agricultural machinery was leased for a long term, the operating cost and working time were reduced by 27.6 to 74.4% and 2.5 to 21.6%, respectively, indicating considerable effect. Conclusions: A long-term lease project needs to be promoted to overcome the limitation of short-term leases of agricultural machinery. The local government should lead this project and facilitate the mechanization of dry-field farming. The department in charge of agricultural machinery lease projects needs to set the working area to cover the rate and maintenance cost for farmers who lease agricultural machinery for the long term.

Shin, Seung-Yeoub,Kang, Chang Ho,Kim, Byounggap,Kim, Yu Yong,Kim, Jin Oh,Lee, Kyou-Seung Korean Society for Agricultural Machinery 2013 바이오시스템공학 Vol.38 No.4

Purpose: This study was performed in order to obtain basic data for policy development and R&D to sharpen competitiveness in domestic agricultural machinery industry by analyzing the recent status of demand and supply for tractor, rice transplanter(riding type), and combine. Methods: Basic data from 199,275 units of tractor, rice transplanter (riding type), and combine was offered by the National Agricultural Cooperative Federation and Korea Agricultural Machinery Industry Cooperative. Those agricultural machines were supplied by the government's loan support from 2003 to 2012. Results: Recent supply of tractor is only 13,000 units or so per annum, thereby being stagnated. Rice transplanter and combine in 2012 corresponded to 3,810 units and 2,490 units, respectively. The domestic market share of the imported agricultural machinery accounted for 60.0% in tractor, 99.5% in saddle rice transplanter, and 80.9% in combine, thereby having been sharply increased 33.1%p, 42.0%p and 53.6%p compared to the ones in 2003. Life spans of tractor, combine and saddle rice transplanter are 3.7, 3.7 and 4.2 years, respectively. Among the discontinued models, the one less than 300 units supplied was occupied up to 70~85%. Conclusions: The domestic demand and the export expansion are needed through developing a model of agricultural machinery of having competitiveness to domestically activate agricultural machinery industry.

농기계 내구연수는 농기계 관련 융자금 상환기간, 이용비용 분석, 수리용 부품 의무공급기간, 손해 보험사의 사고보상을 위한 기준자료로 활용되고 있다. 농기계의 내구수명 기준은 국가에 따라 이용시간 또는 사용연수를 기준하여 활용되고 있다. 우리나라는 사용연수를 기준으로 하는데, 농식품부에서 제공하는 농기계 내구연수 기준이 실제 농기계 사용연수와 차이가 많아 개선이 요구되고 있다 이 연구는 농가현장에 적합한 농기계 내구연수 기준설정을 위한 기초자료로 사용하고자 수행하였다. 농가의 농기계 사용연수 자료는 농촌진흥청에서 2007년부터 주기적으로 조사(조사 시점의 전년도를 기준)한 자료를 활용하였다. 조사표본은 전국 9개도에서 150개 읍면 1,500농가를 대상으로 농기계 생산년도, 연간 사용일수 및 사용시간 등을 현지 면접조사하였으며, 분석결과는 다음과 같다. 농가에서 보유한 농기계의 사용연수는 해가 갈수록 증가하는 추세를 보이고 있다. 2015년 농기계별 평균 사용연수는 경운기 18.4년, 트랙터 11.8년, 보행형이앙기 14.2년, 승용형이앙기 8.2년, 콤바인 8.5년, 곡물건조기 13.9년 등으로 10년 전인 2006년에 비해 농기계에 따라 28.2∼42.7%가 증가하였다. 이는 그동안 농기계의 품질향상과 보급확대에 따른 이용시간 감소로 보다 오래 사용하게되고, 농기계를 고쳐서 사용하는 농가가 증가한 이유로 보인다. 2015년에 농가에서 사용한 농기계의 사용연수와 사용시간과의 상관분석을 실시한 결과 통계적으로 유의한 상관계수를 가진 농기계는 관리기, 트랙터, 승용이앙기, 콤바인, 곡물건조기 등 5기종으로 나타났다. 그러나 이들 농기계도 사용연수와 사용시간에 대한 상관계수가 -0.269이하로 상관관계가 거의 없어 결과적으로 농기계 내구수명은 사용연수를 기준하여 정해야 할 것으로 판단된다. 한편 농식품부에서 제시하는 농기계 내구연수는 경운기, SS기 6년, 트랙터, 곡물건조기, 농산물건조기는 8년, 관리기, 이앙기, 콤바인은 5년으로 정하고 있다. 이는 2015년 농가의 농기계 평균사용연수에 비해 경운기 12.4년, 관리기 7.8년, 트랙터 3.8년, 보행형이앙기 9.2년, 승용형이앙기 3.5년 곡물건조기 5.9년, 농산물건조기 0.5년, SS기 4.5년 정도 짧은 것으로 나타났다. 이는 농기계의 경제성 분석 시 과다비용 계상으로 인한 정책적 오류를 초래할 수 있고, 수리용부품의 공급기간이 실제 농기계 사용연수에 비해 짧아 부품공급 불안정으로 인한 신속한 수리를 어렵게 할 우려가 높다. 또한 농기계 사고에 의한 파손 시 실제 농기계가 가지는 잔존가치보다 매우 적게 받을 수도 있다. 결과적으로 농기계 내구연수를 현실에 맞게 조정할 필요가 있다.

Purpose: This study was performed in order to improve problems and to seek the efficient operating plan by surveying and analyzing the actual status of operating the agricultural machinery rental business supported by the government. Method: The data was collected through two times of survey targeting lease business operators and the leasing business reports published for the past 3 years (``08∼``10) 120 cities and counties. Results: As a result of surveying 120 cities and counties nationwide of operating the agricultural machinery rental business, 96% of agricultural machinery rental businesses were indicated to be operated in the form of short-term rent for about 1∼3 days centering on small-sized agricultural machinery and attachment for upland crop. As for the unit number of possessing rental agricultural machinery and the purchase cost, it was indicated to be greatly reduced the agricultural machinery for rice farming and to be expanded into upland crop whose mechanization is insufficient. The annual rental days (``10) are 9.5 days/unit, thereby being a little insufficient. Rental fee for 1 day is 0.2∼0.8% of the initial purchase cost of agricultural machine, thereby being greatly lower compared to 2.0% (annually 10-day rent) of the proper rents, resulting in being demanded improvement. Conclusions: To be continuously driven the rental business of agricultural machinery with having the ability to propagate, it is judged to be likely to necessarily collect optimum rental fee in consideration of rental days as well as increasing the use days per unit by buying the agricultural machinery, which is secured the rental demand, and by possessing the reasonable unit number.
