This hand brake sensor is a component of the tractor's electrical and brake systems. It monitors the position of the hand brake lever and sends a signal to the machine's control unit, allowing the system to confirm when the brake is engaged or released. The sensor is installed at the hand brake assembly and interacts with the lever mechanism to detect its state. A failed sensor can prevent the control unit from recognizing that the brake is set, which may allow the tractor to be moved or operated with the brake partially applied. As an original AGCO part, the sensor's mounting flange and electrical connector are made to match the original housing geometry, ensuring the switch actuates at the correct lever travel.
