In addition, it provides guidance on the type of information on safe working practices (including information about residual risks) to be provided by the manufacturer.
The purpose of this document is to assist in the provision of safety requirements, means of verification and information for use to ensure an appropriate level of safety for agricultural and forestry tractors and self-propelled machines with functions allowing highly automated operations (see 3.7).
This document deals with all the significant hazards, hazardous situations and events (as listed in Annex A), relevant to agricultural and forestry tractors and self-propelled machines allowing highly automated field operations when used as intended and under the conditions of misuse foreseeable by the manufacturer during normal operation and service.
NOTE 1    While this document gives principles for the design, verification, validation and provision of information for use of a highly automated agricultural machine (HAAM), the detailed specification of requirements for a specific application will be dependent on the machine and its operating conditions. Therefore, the principles for design given in this document need to be extended for specific HAAM by the use of relevant specific (type-C) standards, when available, or by the manufacturer of the machine using risk assessment. Such additional specification of requirements, for design, verification, validation or information for use are outside the scope of this document.
NOTE 2    Safety requirements for specific machines not related to their highly automated operations can be available in machine-specific type-C standards.
This document is not applicable to:
—          forestry applications;
—          mobile, semi-mobile or stationary machinery used for farm yard or barn operations;
—          operations on public roads including relevant requirements for braking and steering systems.
NOTE 3    With respect to implements (e.g. their specific design, functions) and the communication between tractors and implements, additional risks can be relevant and can require additional measures. Such additional measures are outside the scope of this document and are the responsibility of the manufacturer.
This document is not applicable to agricultural and forestry tractors, tractor implement systems, implements and self-propelled machines which are manufactured before the date of its publication.
