Abstract
An agricultural side dressing fertilizer coulter row unit includes a first attachment member adapted to be rigidly connected to a towing frame, and a second attachment member pivotably coupled to the first attachment member for pivoting movement about a substantially vertical axis. A linkage is pivotably coupled to the second attachment member for pivoting movement of the trailing end of the linkage relative to the second attachment member, and a tool-carrying stem pivotably coupled to the trailing end of the linkage carries a rotatably mounted coulter wheel for forming a slit in the soil, a liquid fertilizer dispenser for dispensing fertilizer, and a rotatably mounted closing wheel for closing the slit. A biasing element is pivotably attached to the linkage and coupled to the second attachment member for urging the stem downwardly with a controllable force.
