Claim Text:
1. A pick-up assembly for an agricultural machine comprising: a pick-up drum rotatably mounted in a frame; a windguard extending transversally to an intended direction of crop flow mounted at least one of forward and above the drum at a free end of two lateral support arms, the two lateral support arms being pivotably mounted at their other end to the frame; a crossbar extending transversally to the intended direction of crop flow, the crossbar comprising a plurality of tines mounted at one end to the crossbar and projecting with their free end downstream in the intended direction of crop flow, the crossbar being pivotably mounted to the two lateral support arms for allowing a range of free movement of the free end of the tines between an upper limit and a lower limit; and two elongate flexible tension elements being connected at one end to the crossbar and at their other end to the frame, the ends of the tension elements connected to the crossbar being on opposite sides of the crossbar, a change in an angle of rotation of the support arms causing one of the tension elements to tighten and the other of the tension elements to slacken, the upper limit of the range of movement of the tines being reached when one of the tension elements is taut and the lower limit of the range of movement of the tines being reached when the other tension element is taut.
