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.

An agricultural implement having a main chassis member having a support structure with support arms connected to the support structure for movement between a working position and a transport position, the support arms being provided with operating elements remote from the support structure, the support structure defining a working width between the operating elements and the main chassis member, and the support arms being adjustable in the working position between a length corresponding to minimum working width and a length greater than the minimum working width. In the transport position a distance between the operating elements and the main chassis member is less than the minimum working width. In a headland position the support arms are adjustable such that a distance between the operating elements and the main chassis member is less than the minimum working width.

An agricultural implement includes a first frame member and a second frame member pivotally connected to each other and an actuating assembly configured to rotate the second frame member. The actuating assembly includes a first link pivotally connected to the first frame member, a second link pivotally connected to the second frame member, and a third link attached to an actuator. Two of the first, second, and third links are pivotally connected by a connecting pin, which is received in a slot formed in the third one of the links. The actuating assembly is configured to prevent the pin from moving along the slot and to allow rotation of the second link relative to the third link, when the second frame member is arranged between a retracted position and an expanded position, and to allow the pin to move along the slot, when the second frame member is arranged in the expanded position.

A raking machine includes a traveling vehicle, a rake coupled to the traveling vehicle to rake grass in an agricultural field and form a swath, a sensor to obtain a state of the grass or the swath in the agricultural field, and a controller to change, when the rake performs raking, setting information regarding the rake based on the state obtained by the sensor.

An agricultural implement includes a first frame member and a second frame member pivotally connected to each other and an actuating assembly configured to rotate the second frame member. The actuating assembly includes a first link pivotally connected to the first frame member, a second link pivotally connected to the second frame member, and a third link attached to an actuator. Two of the first, second, and third links are pivotally connected by a connecting pin, which is received in a slot formed in the third one of the links. The actuating assembly is configured to prevent the pin from moving along the slot and to allow rotation of the second link relative to the third link, when the second frame member is arranged between a retracted position and an expanded position, and to allow the pin to move along the slot, when the second frame member is arranged in the expanded position.

An agricultural implement having a main chassis member having a support structure with support arms connected to the support structure for movement between a working position and a transport position, the support arms being provided with operating elements remote from the support structure, the support structure defining a working width between the operating elements and the main chassis member, and the support arms being adjustable in the working position between a length corresponding to minimum working width and a length greater than the minimum working width. In the transport position a distance between the operating elements and the main chassis member is less than the minimum working width. In a headland position the support arms are adjustable such that a distance between the operating elements and the main chassis member is less than the minimum working width.

The present invention provides provide adjustable dual rotary raking machines in which the lateral positions of the rotors and rakes may be moved while in use without stopping operation. The present invention also provides adjustable dual rotary raking machines which are suitable for collecting prunings from agricultural orchards or vineyards having low hanging branches. The present invention further provides adjustable dual rotary raking machines which may be easily collapsed for storage and transport into a small profile that allows multiple options for storing the machines, and does not require special permits to transport the collapsed machines on public roads.

An agricultural implement including a frame, at least one rake moveably coupled to the frame and including a plurality of tine arms, a plurality of tines connected to the plurality of tine arms, and a rotor drive configured for rotating the plurality of tine arms, and an adjustment system configured for adjusting a rake height of the at least one rake. The adjustment system includes at least one actuator, an electronic control unit operably connected to the at least one actuator, and at least one dust sensor supported by the frame and operably connected to the electronic control unit. The at least one dust sensor monitors a dust level and communicates dust level data to the electronic control unit which correspondingly adjusts the rake height based upon the dust level data.
