A ground height gauge assembly is provided. The ground height gauge assembly includes a shaft configured to be rotatably coupled to the header. The ground height gauge assembly includes a first arm coupled to the shaft and configured to simultaneously rotate with the shaft, the first arm defining a first length. The ground height gauge assembly includes a second arm pivotally coupled to the shaft and defining a second length, the second arm configured to be mounted in a first position and a second position. The second length of the second arm is dimensioned greater than the first length of the first arm. In the first position the second arm is configured to rotate independently of the first arm. In the second position the second arm is configured to be coupled to the first arm such that rotation of the first arm simultaneously rotates the second arm.
