<p>The ball press (10) has a rectangular compaction space (18) containing a movable compaction piston (48), supplied with a harvested material via a feed channel (26), with a device for compressing the material in the feed channel and discharging the compressed material into the compaction space. A sensor device with at least 2 sensors (76,78) provides a signal representing the vertical distribution of the material within the compaction space.</p> |
