ABSTRACT:
An improved agricultural machine roll of the tapered revolving type wherein such tapered roll has a series of ribs forming a frusto-conical traction surface. The upper extremity of these ribs have provided, at least proximate thereto, a series of nubs that are located proximate the greatest circumferential dimension of the roll and which extend radially outwardly beyond such ribs. The reduced end of the roll is prefereably thickened so as to reduce chances of fracturing of material proximate the axial hole with which the roll is provided. There will likewise be supplied protuberance means, spaced from said nubs, which are directed essentially radially outwardly beyond the lower portions of the ribs. These will be less in number than the ribs and are designed to impinge upon potatoes or other agricultural pockets so as to lift upwardly and advance forwardly the potatoes, for example, should the rib traction surface become slick as by filling with dirt, mud or other debris.
