ABSTRACT:
The present invention relates to a device for detecting when a cold planer experiences a kickback condition. The device includes a wheel adapted to be connected to the cold planer such that the wheel is caused to rotate in a first direction when the cold planer travels forward, and a second direction when the cold planer travels backward. The device also includes a sensing assembly having an electronic sensor. The sensing assembly is arranged and configured for detecting when the wheel travels in the second direction, and for providing a signal to an on-board computer of the cold planer indicating that a kickback has been detected.
