Abstract
An agricultural planting apparatus includes a chassis and a row unit carried by the chassis that defines a width. The row unit includes a unit body carried by the chassis; a metering device carried by the unit body; at least one furrowing disc carried by the unit body; at least one closing disc carried by the unit body behind the furrowing disc(s); a restraining member carried by the mounting body; and a pressing wheel carried by the unit body, pivotally movable about an axis of rotation relative to the unit body, positionable behind the closing disc(s), and reversibly connectable to the restraining member. The pressing wheel has a constrained pivoting configuration when connected to the restraining member that resists pivoting and a freely pivoting configuration when disconnected from the restraining member to reduce the width of the row unit when pivoted in an upward direction about the axis of rotation.
