ABSTRACT:
A sectored disc assembly, removable disc sector, and method of replacing a disc sector are disclosed for use with a soil opener that uses a disc assembly to open the soil prior to injection of a fertilizer or seed into the ground. The sectored disc assembly includes a rotatable hub and a plurality of disc sectors cooperatively forming a substantially continuous disc around the hub. Connectors, such as bolts, secure each of the disc sectors to the hub. The disc sector includes a body with radially inner and outer margins and side margins that are configured for continuous abutment with adjacent side margins of other disc sectors. The method of replacing a disc sector includes removing the connector securing the disc sector to the hub, moving the disc sector radially outwardly away from the hub, placing a replacement disc sector into contact with the hub, and inserting the connector.
