A self propelled feed mixer can be used for mixing and dispensing feed and weighing accurately to 0.1%. The rotating drum design has no internal moving parts which makes it both easy to clean and easy to maintain. Spin the drum one way and it mixes very thoroughly. Activate the hydraulic cylinder to tip the drum up and then spin it in the other direction and it empties out leaving little more than a film of dust on the inside. This feed mixer is available in a number of versions. A stainless steel or powder coated steel drum can be used to mix feed. The drive-train can consist of a gas engine and hydrostatic drive or an electronic pallet truck can be used to power the feed mixer indoors. Other options are available.
