Abstract
Step-by-step analytical and experimental investigations of the structural system residual operational life using organic fertilizer spreader PRT-9 are developed in this paper. Increased requirements for
metal consumption indicators and reliability of solid fertilizer spreaders are associated with ensuring the strength and durability of their components and units. The agricultural machine frame is the welded metal structure, made
mainly of thin-walled elements of open and closed intersections, operating mainly for bending and torsion. The most common defects of such intersections are fatigue edge cracks.
