摘要：
An agricultural planting apparatus includes a chassis and a row unit carriedby the chassisthat defines a width. The row unit includes a unit body carried by thechassis； a metering devicecarried by the unit body； at least one furrowing disc carried by the unitbody； at least one closingdisc carried by the unit body behind the furrowing disc(s)； a restrainingmember carried by themounting body； and a pressing wheel carried by the unit body, pivotallymovable about an axisof rotation relative to the unit body, positionable behind the closingdisc(s), and reversiblyconnectable to the restraining member. The pressing wheel has a constrainedpivotingconfiguration when connected to the restraining member that resists pivotingand a freelypivoting configuration when disconnected from the restraining member to reducethe width ofthe row unit when pivoted in an upward direction about the axis of rotation.
