Agricultural tractors and machinery - Coding of remote hydraulic power services and controls

Specifies the coding to be used to identify the couplings and controls for the remote hydraulic power services of agricultural tractors, machinery and implements.

Tracteurs et matériels agricoles — Codage des commandes et services hydrauliques à distance

La présente Norme internationale prescrit les codes à utiliser pour identifier les couplages et les commandes destinés aux services hydrauliques à distance des tracteurs, machines ou instruments agricoles. L'identification des couplages et des commandes sera utile aux fabricants d'instruments agricoles pour leur permettre d'identifier les tuyaux souples des intruments par le symbole du vérin rentré ou sorti approprié. Cela les aidera à assurer un fonctionnement correct de l'instrument lorsque celui-ci est relié au tracteur.

Overview

ISO 11471:1995 - Agricultural tractors and machinery: Coding of remote hydraulic power services and controls specifies a uniform coding system to identify couplings and controls for remote hydraulic power services on agricultural tractors, machinery and implements. The standard enables consistent marking of hydraulic couplings and operator controls so implements can be connected and operated correctly and safely.

Key topics and requirements

  • Scope: Coding to identify remote hydraulic power services and their controls for tractors, machinery and implements.
  • Visible identification: Each control and its corresponding coupling on the tractor shall be identified by a common numerical (Arabic) symbol that is visible to the operator at the front or rear connection points.
  • Coupler-to-control mapping: Each coupler must indicate which coupling is connected to the tractor’s pressure source for a specific control position (ensures correct function when connected).
  • Standard hydraulic symbols: Use of established hydraulic symbols defined in related ISO symbol standards:
    • Remote cylinder‑extend (symbol 1570)
    • Remote cylinder‑retract (symbol 1571)
    • Remote cylinder‑float (symbol 1661)
    • Trailer brake system (symbol 1399), if a trailer brake system is provided
  • Reservoir connection: A coupling connected directly to the tractor hydraulic reservoir should be identified according to the standard’s specified symbol (see referenced figure in ISO 11471).

Practical applications

  • Ensures correct implement hookup: Clear, standardized markings reduce the risk of incorrect hose connections and improper implement behavior.
  • Improves operational safety: Operators can identify couplings and controls quickly, minimizing setup errors and hydraulic faults.
  • Facilitates manufacturer interoperability: Implement and tractor manufacturers can provide compatible, clearly-coded hydraulic interfaces for aftermarket and OEM equipment.
  • Supports maintenance and training: Service technicians and operators can use standardized codes to diagnose issues, replace hoses and train staff consistently.

Who should use this standard

  • Tractor and agricultural machinery manufacturers
  • Implement and hydraulic equipment manufacturers
  • Agricultural equipment designers and engineers
  • Service technicians, dealers and fleet managers
  • Standards bodies and safety auditors

Related standards

  • ISO 3767-1:1991 - Symbols for operator controls and other displays (Part 1: Common symbols)
  • ISO 3767-2:1991 - Symbols for operator controls and other displays (Part 2: Symbols for agricultural tractors and machinery)
    ISO 11471 references these symbol standards for consistent graphical identification.

Using ISO 11471 promotes interoperability, reduces connection errors, and standardizes hydraulic control identification across agricultural tractors and implements.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération
mondiale d’organismes nationaux de normalisation (comités membres de
I’ISO). L’élaboration des Normes internationales est en général confiée aux
comités techniques de I’ISO. Chaque comité membre intéressé par une
étude a le droit de faire partie du comité technique créé à cet effet. Les
organisations internationales, gouvernementales et non gouvernemen-
tales, en liaison avec I’ISO participent également aux travaux. L’ISO colla-
bore étroitement avec la Commission électrotechnique internationale (CEI)
en ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l’approbation de 75 % au moins des co-
mités membres votants.
