Abstract
A spreader apparatus is disclosed for spreading manure. The apparatus includes a container which defines an opening for the reception therein of the manure. The container also defines an outlet for the discharge therethrough of the manure. A rotatable feed auger is disposed within and co-operates with the container for feeding the manure through the container. The feed auger has an axis of rotation which extends through the container. A rotatable discharge auger is disposed within the container and co-operates with the container and the feed auger for moving the manure towards the outlet. The discharge auger has a further axis of rotation which is disposed spaced and parallel to and laterally below the axis of rotation of the feed auger. The arrangement is such that when the feed auger and the discharge auger are rotating, the manure is fed by the feed auger from the feed auger to the discharge auger even when the level of the manure drops below the level of the discharge auger so that all of the manure within the container is fed at a substantially constant rate towards the outlet. The spreader apparatus also includes an expeller for expelling the manure through the outlet.
