Ground engaging roller for a field implement

摘要

A roller for a field implement includes projections formed on an outer surface thereof about a circumference of the roller. The projections form adjacent rows parallel to the axis of rotation. The projections of a first row are spaced-apart along a longitudinal length of the roller. The projections of the second row adjacent to the first row are spaced-apart along the longitudinal length of the roller wherein successive projections of the second row are disposed between successive projections of the first row. The projections of a third row adjacent the second row are spaced apart along the longitudinal length of the roller wherein successive projections of the third row are disposed between adjacent projections of the first and second rows. The projections of a fourth row are spaced-apart along the longitudinal length of the roller and are disposed between adjacent projections of the first and second rows not having the projections of the third row.
