ABSTRACT:
A soil cultivator or harrow has a row of soil working members that are driven about upwardly extending axes to work the soil. A plant screen at each lateral side of the implement has a forward guide portion that is pivoted to the front of the frame and a rear, spring-biased portion that normally is held close to the implement's lateral sides. The guide portion of each screen is inclined with respect to the direction of travel to guide plants away from the soil working members during the forward travel of the implement. A pair of arms are pivoted adjacent their front ends to a forward portion of the main frame of the implement, and are connected at their rear ends by a transverse support. The arms are connected to the main frame intermediate their ends by a connection which permits angular adjustment of the arms about their pivots. Each end of the transverse support is connected to a further rearwardly and downwardly extending arm and a roller is supported between the further arms.
