A suspension mechanism for a rotary rake implement incorporates elastomeric shock absorbing members in the corners of a tubular member situated in between the corners of a square rod formed as part of the wheel assembly and received within the tubular member such that the corners of the square rod assert a pre-load spring force on the tubular member when the implement is in an extended operating configuration. The movement of the implement into a folded transport configuration with the weight of the implement supported on the transport wheel assemblies causes a deflection of the square rod that compresses the elastomeric shock absorbing members within the corners of the tubular member to provide maximum suspension for the implement when in transport, while providing minimum suspension when the implement is in operation. An end cap on the square rod engages a stop formed on the tubular member to control rotation.

An implement having a frame for towing by an agricultural vehicle, a lifting arm pivotally connected toward a first end of the frame, a support arm pivotally connected at a first end to a second end of the arm, a working implement carried from a second end of the support arm, a support located between a first end of the lifting arm and the frame which has a working surface. The support element includes a main body with connected first and second support surfaces, a third support surface spaced from the first support surface, a first displaceable element with a contact surface and an opposed support surface, and located between the first and third support surfaces, and a second displaceable element with a first contact surface and an opposed support surface, and located between the second support surface and the third support surface.

The disclosure relates to a tedder comprising a main frame connectable to a carrier vehicle, two pivotal wing arms including at least one carrier beam respectively oriented transversely to the direction of travel, a plurality of rotors arranged on the carrier beams for tedding and turning harvested material and a hydraulic system. The hydraulic system comprises two folding cylinders for folding the wing arms and a pressure closing valve for limiting the hydraulic pressure of the folding cylinders. The hydraulic system further comprises a carrier cylinder for lifting the carrier beams with respect to the main frame, wherein a valve means that is formed and arranged to bypass the pressure closing valve upon actuation.
