Grinder-mixers include a material infeed device such as a feed table for feeding bales of hay to be ground up and incorporated into livestock feed rations. Due to varying bale density, the bale grinder sometimes lugs down when encountering a dense bale. However, if the feed table continues to feed bales during such a lug down, the grinder may clog and stall. A bypass apparatus solves the feed table problem by providing a bypass valve automatically operable to stop motion of the feed table when a lug down occurs.
