Agricultural wheeled tractors Rear-mounted three-point linkage Categories 1N, 1, 2N, 2, 3N, 3, 4N and 4

This technical specification outlines the requirements for rear three-point linkage systems on agricultural wheeled tractors, categorizing them into distinct groups designated as 1.N, 1., 2.N, 2., 3.N, 3., 4.N, and 4. The document establishes specific geometric and functional criteria to ensure compatibility between the tractor and various types of implements. It defines the dimensions, strength, and operating characteristics necessary for safe and efficient attachment of machinery in agricultural settings. The scope covers the mechanical interfaces that facilitate the connection of tools to the rear of the vehicle, addressing critical aspects such as linkage height, distance between lifting points, and hydraulic system integration. Adherence to these guidelines helps maintain uniformity across different manufacturers and ensures that equipment can be interchanged without safety risks. The standard serves as a technical reference for engineers and designers involved in the manufacturing of both tractors and agricultural implements, promoting consistency in the design of lifting mechanisms and their operational parameters within the framework of international best practices.
