Soil cultivating implements

摘要

An agricultural implement has a main frame and laterally positioned carrier frames pivoted to the sides of the main frame. The main frame extends forward to a coupling point for connection to a prime mover. The rear of the main frame mounts a hydraulic piston assembly that is interconnected to each carrier frame to elevate same into an upward tilted transport position. Each frame and carrier frame supports a frame portion having a respective group of rotatable soil working members positioned in a row to work a broad path during working operation. Connecting members on the carrier frames are connected to the central frame portion to raise same when the carrier frames are in their tilted transport positions. Latches supported on the main frame secure beams of the carrier frames in their tilted positions until release. A pair of ground wheels on a mount is pivoted to the main frame and hydraulic connections pivot the wheels to a raised non-transport position or urge the wheels down to support the main frame whereupon latches lock the wheels in the transport position. Springs partly support the carrier frames during operation and further springs urge the wheels downwardly when the latches are disengaged. Each group of soil working members on its frame portion has a parallelogram linkage connection to the remainder of the respective main or carrier frames to permit relative displacements of the groups.
