Agricultural vehicles. Mechanical connections between towed and towing vehicles - Dimensions of hitch-hooks Ingestion-build-156411 The method described here is1 Scope This part of ISO 6489 specifies the dimensional requirements for hitch hooks used in the attachment to agricultural towing vehicles of towed, non balanced trailers and implements equipped with a ring specified in ISO 20019. Its purpose is to ensure the interchangeability of the mechanical connections on agricultural towing vehicles. This part of ISO 6489 1 is applicable only in those cases where the vertical static load does not exceed 30 kN.
