Mechanisms based on piezoactuators

The invention relates to a method in a seedling planting machine and to a seedling planting machine, in which, seedlings are extracted from a seedling storage. In the method, the seedling storage is held in its place on a storage track of the planting machine with first holding elements by a first toothed bar. The seedling storage is transferred on the storage track of the planting machine by moving second holding elements by a second toothed bar, in relation to the first holding elements and to the storage track, so that the seedling storage comes into contact with the second holding elements. The seedling storage is transferred by the second holding elements a transfer distance forward on the storage track. The seedling storage is transferred by the first holding elements, and the seedling storage is detached from the second holding elements.
