ABSTRACT:
A rod weeder attachment including a clamp arrangement for mounting upon a tool bar of an agricultural implement, an arm which extends rearwardly from the clamp and is spring biased downwardly toward the ground, a ground wheel mounted upon the rear end of the arm which is a peripheral surface for running upon the ground and for defining the height of the arm above the ground, a pair of shanks which extend downwardly from the arm, a rod support on a lower end of the shanks in bearings which allow rotation of the rod about its axis and a drive arrangement which communicates drive from the ground wheel to the rod to rotate the rod as it moves through the ground. The arm is formed in two parts a rear part of which carries the ground wheel and is freely pivotal. The free pivot action of the rear part allows the ground wheel to move forwardly when inoperative so that its periphery is below the level of the rod. The rear part can also move rearwardly and upwardly in a pivot action caused by forward movement of the implement so that the rod moves against the ground and its depth is controlled by a rear limit stop against which the rear part engages. The rotation of the ground wheel caused by its initial engagement with the ground drives the rod so that the rod when it engages the ground is rotating and properly enters the ground.
