ISO 6489-5:2019/Amd 1:2025

Overview

ISO 6489-5:2019/Amd 1:2025 is an important international standard issued by the International Organization for Standardization (ISO) focusing on agricultural vehicles. This amendment specifically updates Part 5 of the ISO 6489 series, which covers mechanical connections between towed and towing agricultural vehicles, with a detailed focus on specifications for non-swivel clevis couplings. Non-swivel clevis couplings are critical components used to securely connect towing and towed vehicles in agricultural operations, ensuring safe and reliable mechanical linkage.

This latest amendment, published in 2025, updates key normative references, design requirements, and mechanical connection parameters to align with current industry needs and safety regulations. It supports the ongoing standardization of agricultural vehicle connectors to enhance compatibility, safety, and performance.

Key Topics

• Non-Swivel Clevis Couplings: Specifies technical requirements and design criteria for non-swivel clevis-type couplings used in agricultural vehicles. This includes dimensions, shapes, and mechanical strength features.
• Mechanical Connection Standards: Updates outline permissible mechanical connection combinations based on ISO 22471, ensuring consistent compatibility across different agricultural equipment.
• Design and Safety Enhancements: Introduces revised figures and tables illustrating coupling designs and the permissible configurations for coupling to rings and other mechanical components, promoting safer and more resilient connections.
• Normative References: Incorporates the latest referenced standards such as ISO 22471 on permissible mechanical connection combinations, essential for maintaining interoperability between towing systems.

Applications

ISO 6489-5:2019/Amd 1:2025 offers practical value for manufacturers, designers, and users of agricultural machinery focusing on:

• Tractors and Trailers: Ensuring secure and standardized mechanical connections between tractors and a wide range of towed agricultural implements.
• Agricultural Equipment Manufacturing: Guiding design and production processes to comply with international norms for coupling components, reducing compatibility issues.
• Safety and Compliance: Facilitating conformance with global safety regulations by providing thorough mechanical specifications.
• Maintenance and Replacement: Helping operators and serviced technicians identify suitable coupling parts and configurations adhering to the latest standards, thus enhancing operational reliability.

This standard addresses the essential linkage mechanisms critical for agricultural productivity while minimizing risks related to improper mechanical connections during field operations.

Related Standards

ISO 6489-5:2019/Amd 1:2025 is part of the broader ISO 6489 series concerning mechanical connections between agricultural towing and towed vehicles. Related standards to consider for comprehensive compliance and system design include:

• ISO 6489-1 to -4: Earlier parts covering swivel and other types of couplings and connection methods.
• ISO 22471: Specifies permissible mechanical connection combinations specifically referenced in this amendment.
• ISO/TC 23 (Tractors and Machinery for Agriculture and Forestry): The technical committee responsible for developing and maintaining these standards.
• ISO/IEC Directives: Normative guidelines governing the preparation and maintenance of ISO standards.

By adhering to ISO 6489-5:2019/Amd 1:2025, manufacturers and operators ensure reliable mechanical coupling systems that align with international best practices for agricultural vehicle safety and interoperability.
