The invention refers to a crop feeding apparatus. A pick-up channel is formed between a pick-up unit (62) and a moveable downholder unit. A feeding channel (11) is formed between a crop guiding and processing member (10, 16) and a conveyor (7). A feeding channel actuator (12.1) tends to move at least one part (10) of the crop guiding and processing member (10, 16) towards the conveyor (7), thereby decreasing the cross-section area of the feeding channel (11). Crop material is first conveyed through the pick-up channel and afterwards through the feeding channel (11). A position sensor measures the position of the downholder with respect to the pick-up unit (62). The feeding channel actuator (12.1) decreases the force applied onto the moveable part (10) if the measured position value is above a threshold. This force decrease increases the cross-sectional area of the feeding channel (11). |
