TS ISO 3767-2

TS ISO 3767-2 is the standard that harmonizes symbols used on operator controls and other displays for agricultural tractors and machinery. Its purpose is to help ensure that the same function is recognized through the same or closely related graphic sign across equipment from different manufacturers, supporting clearer and faster operator understanding. In practice, this kind of visual language is especially valuable on machinery with many in-cab controls, indicators, and warnings.

Where this part fits within the symbol family

This part applies specifically to symbols for agricultural tractors and machinery. The supplied scope notes that common symbols used across multiple types of agricultural tractors and machinery, forestry machinery, and powered lawn and garden equipment are covered by ISO 3767-1; powered lawn and garden equipment by ISO 3767-3; forestry machinery by ISO 3767-4; and manual portable forestry machines by ISO 3767-5. So this document focuses on the agricultural tractor and machinery subset within the broader ISO 3767 series.

Why standardized control symbols matter

In general technical terms, control symbols are compact graphical cues that communicate function without relying on text. They are used for functions such as lighting, hydraulics, PTO-related controls, travel direction, adjustments, and status displays. On agricultural equipment, standardized symbols help reduce ambiguity, support consistent operation across brands, and improve usability where multilingual labeling may be impractical. The note pointing to ISO 7000 and IEC 60417 indicates that additional internationally standardized symbols may also be relevant when designing or interpreting machine interfaces.
