Zusammenfassung: | An agricultural harvester (2) comprises a relieving device for a header (3) which is pivotable in two planes about a lower pivot point (7). The relieving device serves to reduce travel resistance, soil compaction and skid wear by providing a relieving force which corresponds to the instantaneous ground loading of the header in its operating setting. The relieving device comprises a connecting rod (10) connected by way of a rearward bearing (9) with a feed shaft (1) of the machine. Tension springs (18) are also articulated at the bearing (9). The rod (10) at its forward end carries a pivot lever (12), at which the tension springs (18) and a header coupler (13) are articulated, the coupler (13) being connected to the header. |
