Описание (английский):

ISO 5692-1:2004 specifies the requirements for the attachment of agricultural non-balanced trailers and implements by means of hitch-rings to the rear of the towing vehicle equipped with either a hook as specified in ISO 6489-1, or a piton-type coupling as specified in ISO 6489-4. Its purpose is to ensure the interchangeability of mechanical connections on agricultural towed vehicles.

Overview

ISO 5692-1:2004 - Agricultural vehicles: Mechanical connections on towed vehicles - Part 1 specifies the dimensions and construction requirements for hitch rings of 50/30 mm cross section used to attach non‑balanced agricultural trailers and implements to the rear of a towing vehicle. The standard ensures interchangeability of mechanical connections when the towing vehicle uses a hook (ISO 6489-1) or a piton‑type coupling (ISO 6489-4). It applies to hitch rings with a 50 mm centre hole and a 30 mm toroidal cross section, located below the rear axle midline and below the tractor power take‑off (PTO).

Key topics and technical requirements

Scope: Attachment of semi‑mounted trailers and implements to tractors via 50/30 mm hitch rings; interchangeability with specified tractor couplings.

Hitch ring geometry: Rings must conform to the dimensional drawings (figures) in the standard - 50 mm ring centre, 30 mm torus diameter (cross section).

Articulation angles: Minimum free movement when hooked:

Yaw (lateral rotation): 60° each side
Pitch (fore/aft tilt): 20° each side (note tractor may have ±3° due to tyre sizes)
Roll (lateral roll): 20° each side
Longitudinal rotation: the towed element should be able to rotate up to 360° about the drawbar longitudinal axis; limiting devices are optional.

Construction:

Hitch rings should be essentially toroidal and manufactured by forging.
Drawbars/timons should be forged and/or machined.
The hitch ring must be securely fixed to the drawbar.

Interchangeability conditions: Compatibility is ensured only when the tractor coupling conforms to ISO 6489‑1 or ISO 6489‑4 and when the ring and drawbar dimensions meet the standard.

Applications and who uses it

ISO 5692-1:2004 is used by:

Tractor, trailer and implement manufacturers specifying or designing hitch rings (50/30 mm) for agricultural equipment.

Component suppliers and forging shops producing standardized hitches.

Farm equipment engineers, maintenance teams and workshops verifying compatibility and safe articulation.

Procurement and compliance personnel writing specifications to ensure interchangeability and safety across fleets. Practical uses include design validation, procurement specs, retrofit compatibility checks and manufacturer quality control.
