TS ISO 3767-3

TS ISO 3767-3 is the document that standardizes symbols used on operator controls and other displays for powered lawn and garden equipment. In practical terms, it establishes a common visual language for functions on these machines so that control markings are clearer, more consistent, and less dependent on wording or language.

Why these symbols matter

On lawn and garden equipment, symbols help users quickly identify what a switch, lever, indicator, or setting means. This is especially valuable for functions that require immediate recognition, such as starting, stopping, speed adjustment, cutting operation, or other safety-related controls. In general technical use, symbols reduce reliance on text and support a more universal interface across markets and languages.

What this part covers

The scope of this part is limited to symbols for operator controls and other displays on powered lawn and garden equipment. Its notes also place it within the wider ISO 3767 system: ISO 3767-1 covers common symbols across multiple agricultural, forestry, and lawn and garden machine types; ISO 3767-2 covers agricultural tractors and machinery; ISO 3767-4 covers forestry machinery; and ISO 3767-5 covers manual portable forestry machines. For additional internationally standardized symbols, ISO 7000 and IEC 60417 may also be consulted.

Technically, the document supports consistency in the visual language of machine operation. When symbols are chosen and applied consistently, equipment becomes easier to understand and operate, and the same graphic mark can carry the same meaning across different products and manufacturers.
