Abstract
In a crop feed grinding and mixing apparatus having a mixing means mounted to a mobile frame, a grinding means fixed to the frame, material transfer means extending at least between the grinding means and the mixing means, material infeed means in material flow communication with the grinding means and drive means including a rotatable shaft operably connected to the mixing, grinding, material infeed and material transfer means, there is provided a speed responsive overload protective device mounted to the rotatable shaft so that when the drive means is slowed in operation below a predetermined speed by excessive crop feed accumulation in the grinding means the protective device automatically disengages the material infeed means from the drive means. The disengagement of the material infeed means permits the grinding means to continue to operate without any additional crop feed being delivered thereto, until the rotatable shaft returns to the predetermined speed at which time the protective device will automatically reengage the infeed material means to permit the flow of crop feed to recommence.
