An agricultural implement comprising: a drawbar having a towing point or linkage at a front end; a frame having left and right hand wings (10, 11) foldable between an extended working configuration, where the wings (10, 11) extend outwardly to respective sides of the drawbar, and a retracted transport configuration, where the wings (10, 11) are folded in towards a longitudinal axis of the implement, a proximal end of each wing (10, 11) being pivotally connected to the drawbar at or towards a rear end of the drawbar, so that together with the drawbar the wings (10,11) define a frame of the implement; a plurality of spaced apart tools attached along each wing (10, 11); and a bracing arrangement (21 to 25) for maintaining the wings (10, 11) in the working configuration, the bracing arrangement comprising: a left hand bracing member pivotally connected at a distal end to the left hand wing at a point remote from the proximal end of the left hand wing; and a right hand bracing member pivotally connected at a distal end to the right hand wing at a point remote from the proximal end of the right hand wing, wherein the left and right hand bracing members (20, 21) are directly or indirectly, pivotally connected together at their proximal ends and are arranged in the working configuration to be held at a predetermined angle relative to each other in order to retain the wings (10, 11) in the working configuration, wherein the proximal end of each wing (10, 11) is pivotally connected to the drawbar at a fixed location and in further comprising a drawbar extension member connected at a front end to the drawbar at or towards the rear of the drawbar and connected at a rear end to the proximal ends of the bracing members (20, 21), the extension member being arranged to move between a retracted position, where the proximal ends of the bracing members (20, 21) are in a forward position retaining the wings (10, 11) in the transport configuration and an extended position where the proximal ends of the bracing member (20, 21) are in a rearward position and the bracing members act in compression to retain the wings (10, 11) in the outwardly extending working configuration. a drawbar having a towing point or linkage at a front end; a frame having left and right hand wings (10, 11) foldable between an extended working configuration, where the wings (10, 11) extend outwardly to respective sides of the drawbar, and a retracted transport configuration, where the wings (10, 11) are folded in towards a longitudinal axis of the implement, a proximal end of each wing (10, 11) being pivotally connected to the drawbar at or towards a rear end of the drawbar, so that together with the drawbar the wings (10,11) define a frame of the implement; a plurality of spaced apart tools attached along each wing (10, 11); and a bracing arrangement (21 to 25) for maintaining the wings (10, 11) in the working configuration, the bracing arrangement comprising: a left hand bracing member pivotally connected at a distal end to the left hand wing at a point remote from the proximal end of the left hand wing; and a right hand bracing member pivotally connected at a distal end to the right hand wing at a point remote from the proximal end of the right hand wing, wherein the left and right hand bracing members (20, 21) are directly or indirectly, pivotally connected together at their proximal ends and are arranged in the working configuration to be held at a predetermined angle relative to each other in order to retain the wings (10, 11) in the working configuration, wherein the proximal end of each wing (10, 11) is pivotally connected to the drawbar at a fixed location and in further comprising a drawbar extension member connected at a front end to the drawbar at or towards the rear of the drawbar and connected at a rear end to the proximal ends of the bracing members (20, 21), the extension member being arranged to move between a retracted position, where the proximal ends of the bracing members (20, 21) are in a forward position retaining the wings (10, 11) in the transport configuration and an extended position where the proximal ends of the bracing member (20, 21) are in a rearward position and the bracing members act in compression to retain the wings (10, 11) in the outwardly extending working configuration.
