Agricultural Implement with Compound Hinge Arrangement

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.

1. A method of folding an agricultural implement from an unfolded field-use position to a folded transport position, the method comprising:
actuating a first actuator moving a first frame segment of an agricultural implement to a first position by pivoting the first frame segment about a first pivot axis of a compound hinge arrangement, wherein the first position corresponds to a partially folded position of the first frame segment with respect to a second frame segment of the agricultural implement; and actuating a second actuator moving the first frame segment of an agricultural implement to a second position by pivoting the compound hinge arrangement about a second pivot axis of the compound hinge arrangement, wherein the second position corresponds to a folded position of the first frame segment with respect to the second frame segment of the agricultural implement.
