摘要：
An agricultural implement is provided that includes a compound hinge arrangement that allows for compact folding adjacent frame segments such as wing segments of planting, seeding, or tillage implements. The compound hinge arrangement includes a first pivot axis that can be active when the implement is in an unfolded field-use position in which a second pivot axis of the compound hinge arrangement is locked. The implement may be folded into a folded transport position by pivoting an outer wing about the first pivot axis with a first actuator during a first stage and pivoting the compound hinge arrangement and the outer wing about the second pivot axis during a second stage.
