The original gearbox position sensor, part number 3796579M1, is an electronic component used in agricultural tractors to monitor the position of the gearbox. It is usually mounted on the gearbox housing and is used to transmit information about the current gear position to the tractor's control system. This sensor works on the principle of a magnetic detector that detects changes in the magnetic field around it. It consists of two main components - a magnetic sensor and a shaft with a magnet. This shaft is placed in the gearbox, and the magnetic sensor is attached to the gearbox housing. When the shaft shifts with a change in position relative to the sensor, which causes changes in the magnetic field and thus triggers a signal that is sent to the tractor control system. The gearbox position sensor with part number 3796579M1 is robust and resistant to the operating conditions of agricultural tractors. Its design allows precise and reliable detection of the gear position, which is important for the correct operation of the gearbox and the entire drive train of the tractor. Installation and replacement of such a sensor does not require specialized knowledge or tools , so you can do it yourself in a home workshop or at an authorized tractor service center.
