Scope
ISO 6489-3:2021 specifies dimensional requirements and location for category 0 to category 5 drawbars mounted on the rear of agricultural tractors.
Dugong relevance
A tractor-towed scraper depends on a compatible towing interface. Tractor category, drawbar, hitch hardware, vertical and horizontal loads, and manufacturer limits all need to be checked for the actual combination.
No automatic conformity claim
The existence of this standard does not establish that every Dugong hitch or every tractor combination conforms. Verify the installed connection and engineering documentation.
