Purpose and Scope 

The purpose of the Standard is to provide uniform terminology and definitions for planters, drills and seeders.

Dimensions, spacings, depths of operations, widths or velocities may be used as a part of the implement specifications. These should not be considered as performance specifications for any type of design or publication. 

This Standard is limited to those machines and machine components used for the establishment of field crops. 

This Standard is intended to be consistent with terminology in other ASABE standards including ASABE Standard S414.1, Terminology and Definitions for Agricultural Tillage Implements, ASABE Engineering Practice EP291, Terminology and Definitions for Soil Tillage and Soil-Tool Relationships, and ASABE Standard S477, Terminology for Soil-Engaging Components for Conservation - Tillage Planters, Drills and Seeders.
