TS ISO 3767-2

TS ISO 3767-2 is a symbol-based terminology and marking standard for operator controls and other displays used on agricultural tractors and agricultural/forestry machinery. In practical terms, these symbols help users recognize the same control, indicator, or display function more quickly, especially where text labels may be limited, multilingual, or impractical on machine interfaces.

How operator symbols support machine interfaces

From a general technical perspective, operator symbols are simple graphic signs placed on buttons, levers, switches, indicators, or screens to communicate function as clearly and consistently as possible. On tractors and related machinery, that visual language matters because equipment is used in varied field conditions and often by operators who may move between different machines or brands. This standard defines symbols for that context; it is about the symbol set itself rather than a detailed test method or performance limit.

What the scope focuses on

• Symbols for agricultural tractors
• Symbols for machinery used in agriculture and forestry
• Markings used on operator controls
• Symbols used on other displays
• Although the broader series title mentions powered lawn and garden equipment, this part is focused on agricultural tractors and machinery

This TSE listing represents a withdrawn edition of the standard. In general engineering use, standardized symbols help support interface consistency, quicker recognition, and reduced chance of control confusion. Knowing the symbol framework covered by this document is useful when designing panels, selecting control graphics, or aligning operator training with a common visual language.
