    • A hydraulically operated folding mechanism for ground working implements wherein substantially rectilinear movement of the piston rod of a hydraulic actuator causes one section of the implement to rotate substantially 180.degree. relative to another section thereof. This enables a relatively large implement to be made small and compact for purposes of storage and transport. It further includes members for permitting the several sections to pivot relative to each other when in operating position so that the implement can conform to the contour of the ground and locking structure which prevents such pivotal movement as soon as the folding mechanism becomes operative.
    • 一种用于地面作业工具的液压操作的折叠机构,其中液压致动器的活塞杆的大致直线运动导致工具的一部分相对于其另一部分大致旋转180度。 这使得相对较大的工具可以小型化和紧凑化,以用于存储和运输。 它还包括用于在操作位置时允许多个部分相对于彼此枢转的构件,使得该工具能够与折叠机构变得可操作时防止这种枢转运动的地面和锁定结构的轮廓一致。
