Abstract: This article presents a methodology for quantitatively assessing the impact of the technical readiness coefficient of grain harvesting equipment on regional grain self-sufficiency, a key indicator of the production component of food security. Using the Ryazan Region as a case study, a comprehensive analysis of combine fleet dynamics and total grain harvest for 2024-2025 was conducted. An empirical model was developed to predict operational technical readiness based on equipment service life, enabling the conversion of physical wear metrics into direct economic losses. The study shows that a decline in the readiness coefficient from 0.95 to 0.6 increases grain losses by 22 percentage points, resulting in annual economic damage exceeding 10.4 billion RUB at November 2025 baseline prices (11,950 RUB/t). Raising technical readiness to the planned level of 0.8 reduces harvesting costs by 33%, improves cost efficiency by 1.7 times, and increases regional self-sufficiency from 213% to 248%. Practical recommendations for differentiated machine and tractor fleet (MTF) renewal and targeted leasing subsidies confirm the economic feasibility of accelerated MTF modernization to strengthen agricultural production potential.
