ABSTRACT:
A packer roller for a soil cultivating implement constructed to perform a soil cultivating operation in addition to that performed by any other soil cultivating members of the implement, the roller comprising a plurality of groups or crowns of six tine-like or tooth-like projections spaced apart from one another at regular intervals along the roller's axis of rotation which are connected to a central tubular support of that roller. Each projection has a relatively sharp rear edge with respect to the roller's usual direction of rotation and, inward from the sharp edge, a relatively blunt leading edge relative to such direction so that it first penetrates into the soil relatively easily and then resists forward progress through the soil thus tending in a positive sense to produce rotation around the roller's axis of rotation. The projections are formed from pairs of shaped plates and each plate includes a sleeve surrounding the central tubular carrier of the roller. Scrapers cooperate with the convex surfaces of these sleeves between the projections.
