Abstract: Vehicle-mountable animal feed spreader device for spreading feed for livestock, game animals, or other animals. The device is configured to mount to a vehicle. The device is also configured so that it can be activated while driving to spread feed. The animal feed spreader includes a hopper that funnels animal feed towards a spinning plate that is driven by a motor to spin. Animal feed falling through the hopper strikes the spinning plate as it spins, which spreads the animal feed away from the spinning plate as the vehicle moves or is stationary. A protective cage surrounds the spinning plate and may also operate as a pedestal or other base. The motor and spinning plate are attached to a removable floor of the hopper.
