Contribution of the Virgin Land Branch of GOSNITI to the Creation of a Repair and Maintenance Base for Tractors K-700A and K-701

Tractors K-700A and K-701 of the Kirovets family manufactured by Kirovsky Zavod have been used in agriculture for more than fifty years and their effective operation would have been impossible without the established repair and maintenance base; vast regulatory and technical documentation; equipment for maintenance and repair. ( Research purpose ) The research purpose is analyzing the development and production experience of the Virgin Land Branch of GOSNITI to improve the efficiency of servicing high-power tractors obtained during the creation of the repair and maintenance base of tractors K-700A and K-701. ( Materials and methods ) Conducted an analysis of the developed regulatory and technical documentation and equipment for the organization of repairs. The repair and maintenance base for Kirovets tractors created on their basis made it possible to ensure the required level of readiness and maintain reliability indicators. ( Results and discussion ) It was shown that the created repair and maintenance base corresponded to the needs of the time and provided high technical and economic performance indicators in accordance with the current GOST. The time and material resources spent on the search for causal relationships between the parameters and operating conditions of tractors affecting operational reliability; depending on the operating conditions; the completeness of routine maintenance work carried out; the quality assessment of repairs carried out; the input quality control of new and refurbished spare parts; were significantly reduced. ( Conclusions ) The experience of the Virgin Land Branch of GOSNITI has shown that an integrated state approach to the implementation of large projects proves its economic efficiency; which amounted to 1.5-4.4 rubles of profit per ruble of state investment in the 1980s. The result of this approach was the development of more than 75 results of development work and their serial or individual implementation; which made it possible to improve the repair and maintenance base for more than 100;000 repairs per year; which is currently of particular relevance for ensuring food security of the Russian Federation.
