ABSTRACT:
A soil engaging roller has a central axis shaft and spaced apart plate-like supports secured to the shaft. The supports are upwardly extending with holes around their perimeters to receive elongated rod-type elements that form the periphery of the roller. The elements can have retaining devices in the form of transverse holes with pins that secure the elements in the holes of the supports. The rods are shiftable or reversible with respect to the supports so that as the contacting surfaces become worn the elements can be altered to occupy different longitudinal positions. The support holes can be punched out with bearing surfaces formed by the bent over rim. Also, the supports can be angled with respect to the shaft and the elements can have several transverse retaining holes to permit shifting and retaining of the elements to the supports.
