This standard specifies the main connection dimensions and working requirements of hydraulic quick-change couplings defined in GB/T5860 that transmit hydraulic power from agricultural tractors to agricultural implements. This standard applies to quick-change joints (hereinafter referred to as quick-change joints) of hydraulic lines other than brake lines (see GB/T 25399). NOTE: All quick couplings require frequent connections and disconnections in order to connect implements to different tractors without the use of tools or special devices.
