Abstract: A conveying device for conveying crop material from a pick-up mechanism to a baler comprises a conveying channel having a base comprising an upstream base part and a downstream base part. The downstream end of the upstream base part is supported on a pair of first resilient mounting members and the upstream end of the downstream base part is supported on a pair of second resilient support members. The first and second resilient support members, in response to the force with which crop material is being urged by the feed rotor against the upstream and downstream base parts exceeding respective first and second predefined values, yield. This results in downward displacement of the upstream base part and the downstream base part to permit crop material to pass through the conveying channel.
