Agricultural vehicles — Mechanical connections on towed vehicles — Dimensions for hitch rings ISO 20019:2001

Publication date:   Jul 12, 2001

Scope

This International Standard specifies dimensional requirements for the attachment of agricultural, non-balanced
trailers and implements by means of hitch rings to the rear of towing vehicles equipped with a hook specified in ISO
6489-1. Its purpose is to ensure the interchangeability of the mechanical connections on agricultural towed
vehicles.
This International Standard is applicable to rings whose coupling point is below the centre-line of the rear axle and
the power take-off (PTO) of the tractor.
NOTE Other International Standards are to be developed for rings above the PTO coupling.
