The purpose of developing a high-performance locking pin is to ensure a safe, protected, and standardized connection between the power source (tractor) and the working unit (agricultural implement). The current state of the art in the manufacturing of locking pins has evolved from simple forged parts to high-precision components integrated into a digitalized system. Today, a pin is no longer just a steel rod, but the result of an advanced optimization process. The choice of OL 45 demonstrates a rational design focused on an optimal cost-quality ratio. By applying induction hardening only in the contact area, the OL 45 pin can achieve performance close to that of expensive alloy steels. The novelty does not lie in “reinventing the wheel,” but in the technological refinement of a critical component, transforming a simple OL 45 pin into a highly reliable part, perfectly adapted to the requirements of precision agriculture. The design of this locking pin demonstrates that, through the proper use of simulation software and CNC machines, a conventional material such as OL 45 can be optimized to meet the rigorous demands of modern agricultural engineering. The synthesis of results obtained during the design and manufacturing process of the OL 45 steel locking pin highlights the convergence between classical machining methods and advanced digital workflows. The study demonstrates that the integration of modern technologies not only optimizes the techno-functional parameters of the component but also redefines standards of reliability and performance in the agricultural machinery sector.
