Patent ID: 8733074

Claim:
An adjustable rake assembly comprising: a frame comprising a main axial member defining a front end and a back end and a transverse member fixedly attached to the main axial member proximate the back end; two wings movably attached to opposed ends of the transverse member, wherein each wing comprises at least two rakes attached thereto, a telescoping rake connection, and a rotating rake connection, the telescoping rake connection being configured to effect retraction of at least a second rake of each wing relative to a first rake of the wing, the rotating rake connection being configured to effect rotation of at least the second rake of each wing relative to the first rake of the wing, wherein at least the second rake of each wing is configured to be moved with respect to the frame between a first position and a second position via the telescoping rake connection and the rotating rake connection; a driveline at least partially disposed with the main axial member that is configured to transmit power from a tractor connected to the rake assembly at the front end of the main axial member to a baler connected to the rake assembly at the back end of the main axial member; a first set of hydraulic cylinders and corresponding linkages pivotally connecting the transverse member of the frame to an end of each wing; a second set of hydraulic cylinders and corresponding linkages pivotally connecting the main axial member of the frame to a location of each wing spaced from the end of the wing pivotally connected to the transverse member; a plurality of position sensors configured to detect a position of the first and second sets of hydraulic cylinders; and a control system configured to actuate at least one of the first and second sets of hydraulic cylinders based on data received from the position sensors, wherein each wing is configured to be moved with respect to the frame to at least a field position in which the wings are spaced away from the main axial member for raking operations.
