What color means to engage the power take-off (PTO)?

The color yellow is used to signify the engagement of the power take-off (PTO) on tractors and agricultural machinery. This color coding is part of a standardized system designed to enhance safety and ensure that operators can quickly identify critical controls and components. Yellow typically indicates that a mechanism should be engaged, drawing attention to the action required for powering various attachments, such as mowers or rotary tillers.

In the context of tractor operation, understanding these color codes is essential for safe handling. The use of yellow specifically helps prevent accidental engagement while also providing a visual cue for operators that alerts them to perform necessary actions safely. Proper knowledge of these color codes contributes significantly to effective training and safe operational practices in agricultural settings.
