Track adjustment assembly to reduce vibration

The subject invention includes a track assembly for a mobile machine such as an earth-moving machine. The track assembly includes continuous track driven about a track frame. A drive wheel, an idler wheel and a number of carrier wheels are rotatably supported by the track frame and engage the track. An adjustment device is connected to the track wheel. The adjustment device adjusts a relative position of one of the track wheels to tension the track. A controller is connected to the adjustment device to control the adjustment of one of the track wheels. A sensor is disposed adjacent the track and connected to the controller. The sensor is adapted for sensing vibrational forces, or track noise, of the track and transmitting the parameters of the forces to the controller to automatically adjust the track.
