An attachment for use with an agricultural implement to protect a row of emergent plants growing in a field. The device includes a shield which protects the plants from accumulations of soil, trash, and other debris. The shield is mounted between one or more claws of the implement, on one hand, and the row of plants to be protected on the other hand. Means, such as a motor, are provided to drive the shield in a plane generally parallel to the row of plants. As the shield is positively rotated, a periphery of the shield passes closely proximate the surface of the ground in which the row of plants is located. Such driving of the shield is in a direction in which the shield would rotate if it were allowed to freewheel and were made to rotate as a result of its engagement with the ground.
