A system and method for managing the transfer of agricultural material from a harvesting vehicle to a receiving vehicle comprises a stereo imaging device 10 facing towards a storage portion 85 of a receiving vehicle, a fill level estimator estimating a plurality of fill levels of a plurality of corresponding subdivided volumes or cells, the fill levels associated with respective heights of agricultural material in the cells, a spout identification module and an alignment module for determining the relative position of the spout and the cells and moving the spout so that it is aligned with a target fill zone in accordance with a fill sequence in which the alignment module a) directs the spout to fill the container 85 to a first target level 310, b) the fill level estimator estimates the number of cells below the first target level and c) the alignment module directs the spout to fill the container in a second mode to a second target level 312 that is greater than the first target level.
