Terminology for Soil-Engaging Components for Conservation-Tillage Planters, Drills, and Seeders

Published by: The American Society of Agricultural and Biological Engineers / 08/01/2013 / 15 pages
1.1 The purpose of this Standard is to provide uniform terminology for the soil-engaging components of
planters, drills and other seeders used in conservation-tillage systems so as to improve communication among
those who design, develop, produce, sell, service, demonstrate and report the performance of such machines.

1.2 This Standard is limited to machine components for planters, drills and other row-type seeders used for
establishing field crops with conservation-tillage systems. It does not include components for aerial, broadcast
or other random-pattern seeding machines, nor those used exclusively for seeding vegetable or other specialty

1.3 This Standard is limited to those machine components that actively engage and/or penetrate the soil during the
seeding operation and which affect the total performance of the seeding machine.

1.4 This Standard includes numerous references to, but does not attempt thorough descriptions of, machine
frames or transport components, drive mechanisms, metering devices, suspensions for seeding units, and
hoppers and containers for seed or other materials that may be applied during the seeding operation.

1.5 Dimensions, spacing, operating depths and velocities are used in some cases as part of the component
descriptions. These are for informational purposes only and do not imply performance specifications for any type of
component design, soil condition, or seeding practice.

1.6 This Standard is intended to be consistent with terminology in other ASAE standards including ASAE Standard
S414, Terminology and Definitions for Agricultural Tillage Implements, and ASAE Engineering Practice EP291,
Terminology and Definitions for Soil Tillage and Soil-Tool Relationships.
