A system for automatic tilting of an operator cabin of a work machine includes a first sensor that generates a first signal indicative of a first pitch angle of a frame structure relative to a non-inclined surface. The system also includes a tilting mechanism to tilt the operator cabin relative to the frame structure. The system further includes a controller that receives the first signal indicative of the first pitch angle. The controller determines a second pitch angle based on the first pitch angle. The controller controls first and second actuators to tilt the operator cabin by the second pitch angle relative to the non-inclined surface. The second pitch angle is opposite in direction to the first pitch angle. Further, based on a tilting of the operator cabin, a plane defined by the operator cabin is substantially parallel to the non-inclined surface.
