Motorized feed carts allow livestock producers to mix and feed rations to their animals without having to scoop the grain or fork the silage. (They're also used to dispense bedding.) These battery-powered carts, which are designed to be compact enough to navigate tight corners in barns, feature hydrostatic drives so they can be driven at various speeds while the mixed feed is unloading and discharge doors so the silage can't spill during mixing and transport. The operator rides or walks and steers from the rear of the device.
