ABSTRACT:
An improved paddle design for use on the beater mechanism of a manure spreader enables the spreader to satisfactoriloy handle a broader range of manure consistencies and to distribute the same over a more uniform and wide spread pattern. The paddle has a dished or cupped shape, is substantially symmetrical about its centerline, and includes a curved main body portion and integrally formed upper engaging and lower mounting portions. The upper portion has a curved shape similar to the main body portion and is inclined inwardly toward the axis of curvature of the main body portion, thus providing a concave working surface. The lower portion presents a planar surface for mounting the paddle on a beater shaft. The paddle, being symmetrical, can be used on either the left or right sides of a spreader.
