Abstract
A milling machine includes a primary drum drive assembly that is adapted to rotate a milling drum, and a ground-engaging drive assembly that is adapted to drive the milling machine along a roadway. A lifting column includes a linear actuator which can be operated to raise and lower the frame of the machine with respect to the roadway. A sensor that is mounted to the lifting column is adapted to determine if the lifting column is not supporting at least a predetermined portion of the weight of the milling machine. A controller is operatively attached to the primary drum drive assembly and to the sensor. The controller is adapted to receive from the sensor a signal indicating that the lifting column is not supporting the predetermined portion of the weight of the milling machine, and upon receipt of such signal, to stop the rotation of the milling drum.
