Abstract
A seeder element of an agricultural machine includes a seed distribution element and a tamping device. The tamping device is arranged behind an outlet of the seed distribution element in a direction of advance at work of the seeder element. The tamping device includes an adjustment device and a tamping element. The tamping element exerts a tamping force on the ground in at least one work position of the adjustment device. The at least one work position of the adjustment device is a load-relieving position in which the adjustment device exerts, on the tamping element, a load-relieving stress that counters the weight of the tamping element.
