Overview
ISO 4002-1:1979 - Equipment for sowing and planting - Part 1: Concave disks type D1 - Dimensions defines the dimensional requirements for concave disks used in sowing and planting machines. The standard establishes the official geometry and tolerances for concave disks (type D1), with or without a central hole, to ensure compatibility and interchangeability across agricultural machinery and seeders.
Key topics
- Scope and applicability: Dimensions for concave disks used in sowing and planting equipment (type D1).
- Dimensional parameters defined: outside diameter, central-hole diameter (if present), fixing-hole diameter, pitch circle diameter, disk thickness, height of concavity (t) and radius of concavity (R).
- Sizes covered: a tabulated set of dimensions for Sizes I to IV (values given in millimetres in the standard).
- Fixing and positional tolerances:
- Fixing-hole centre tolerance: within 0.2 mm diameter of true position.
- Radius of concavity tolerance: +5% of R.
- Reference notes: dimension t is given for reference in the table.
- Illustrations: figure shows section views and labels for the various dimensions to aid interpretation.
Applications
ISO 4002-1:1979 is intended for:
- Manufacturers of sowing and planting machines and replacement disks - to produce components to a recognized dimensional standard.
- Design engineers specifying disk geometry for seeders and planters to ensure fit and performance.
- Parts suppliers and distributors ensuring replacement concave disks meet dimensional and tolerance requirements.
- Quality control and inspection teams verifying conformity of disk parts to specified tolerances.
- Procurement and maintenance departments seeking interoperable parts for agricultural machinery fleets.
Benefits include improved interchangeability of disks between machines, predictable performance of seeding equipment, simplified maintenance and spare-parts sourcing, and compliance with an internationally recognized dimensional reference.
Related standards and context
- Developed by ISO/TC 23 (Tractors and machinery for agriculture and forestry).
- ISO 4002-1 is Part 1 of the disks series; consult the ISO catalogue or national standards bodies for related parts or subsequent revisions.
Keywords: ISO 4002-1:1979, concave disks, sowing and planting, seeders, agricultural machinery, disk dimensions, fixing holes, pitch circle diameter, radius of concavity, tolerance.

FOREWORD
ISO (the International Organization for Standardization) is a worldwide federation
of national Standards institutes (ISO member bodies). The work of developing
International Standards is carried out through ISO technical committees. Every
member body interested in a subject for which a technical committee has been set
up has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the ISO Council.
International Standard ISO 4002/1 was developed by Technical Committee
ISO/TC 23, Trattors and machinery for agriculture and forestry, and was circulated
to the member bodies in March 1977.
lt has been approved by the member bodies of the following countries :
Australia Germany, F. R. South Africa, Rep. of
Austria
Iran Spain
Belgium
Italy Sweden
Brazil Korea, Dem. P. Rep. of Switz

AVANT-PROPOS
L’ISO (Organisation internationale de normalisation) est une fedération mondiale
d’organismes nationaux de normalisation (comités membres de I’ISO). L’élaboration
des Normes internationales est confiee aux comités techniques de I’ISO. Chaque
comité membre interessé par une étude a le droit de faire partie du comité technique
correspondant. Les organisations
internationales, gouvernementales et non
gouvernementales, en liaison avec I’ISO, participent egalement aux travaux.
Les projets de Normes internationales adoptés par les comités techniques sont
soumis aux comités membres pour approbation, avant leur acceptation comme
Normes internationales par le Conseil de I’ISO.
La Norme internationale ISO 4002/1 a été élaborée par le comité technique
lSO/TC 23, Trecteurs et math‘els egricoles et forestiers, et a été soumise aux
comités membres en mars 1977,
