ISO/TC 23/SC 7/WG 12 - Combine harvesters, forage and cotton harvesters

This document specifies test methods for evaluations of forage harvester function and performance, covering forage harvesters which cut the crop directly at full width or from spaced-apart plant rows, or which pick up pre-cut crop. It applies to forage harvesters with driven knives for chopping and which deliver the chopped crop into a container or a separate vehicle or trailer. The forage harvesters can be tractor-mounted, trailed or self-propelled.

This document specifies terms and definitions related to forage harvesters and their component parts. This document identifies dimensions and other characteristics aimed at allowing comparison of operations of the machines and to improve communication among engineers and researchers, in association with ISOÂ 8909-2, which lays down methods of measuring characteristics and performance requirements for the term defined.

This document specifies the methods and requirements in assessing the dimensions and performance of a forage harvester, as defined in ISOÂ 8909-1, and its functional components. It also allows comparison of forage harvester performance through comparative testing.

This document specifies a preferred method for determining and designating the capacity and unloading rate of combine harvester grain tanks and unloading systems.
