PROBLEM TO BE SOLVED: To provide the support apparatus of a farm machine, which vertically rotatably supports a ridger on a support frame rotation shaft, upward or downward rotates the ridger on the rotation shaft to switch the position of the ridger into a work position placed on the lower side of the rotation shaft or into a non-work position placed on the upper side of the rotation shaft, and does not highly change the lifting force of the farm machine between the work position and the non-work position. SOLUTION: This support apparatus of the farm machine is characterized by disposing a spring 35 for energizing in the direction for upward rotating the ridger on the rotation shaft 22 to reduce a force for lifting the ridger, and further disposing a ridger rotation-assisting mechanism 34 for changing the rotation moment on the rotation shaft 22 due to the energizing force of the spring 35 in response to the change of the rotation moment on the rotation shaft 22 due to the self weight of the ridger between the work position and the non-work position, so that a large change is not caused on the force for lifting the ridger.
