摘要:
An agricultural implement, such as a row crop planter, has a main carrier frame drawn by a tractor and including support wheels. Individual row units are mounted on a lift frame. The carrier frame includes a cornered lift post which is mounted for rotation about a vertical axis. A cornered sleeve or collar in the form of a tube is mounted to the lift frame for vertical sliding motion on the lift post. A lift hydraulic cylinder couples the lift frame to the carrier frame for setting the lift frame in (i) a use position wherein the row units are lowered to engage the soil; (ii) an intermediate, raised position wherein the row units are disengaged, for negotiating end turns; or (iii) a fully raised position wherein the lift frame and row units may be rotated from a transverse position to a longitudinal position, to narrow the implement for road travel. A swing hydraulic cylinder is arranged to rotate the lift post when the lift frame is raised to the uppermost position, to torque the lift frame to a longitudinal position for transport.
