Abstract
The invention refers to centrally adjustable actuators for devices for piling up, collecting or handling earth or mulch, which, depending on the weight of the device, can be used geared up, reduced or linearly. The actuators each have toothed segments with several teeth, which are connected with chain link type pinions fixed in the direction of adjustment but yielding and pivoted. The chain link type pinions are designed to pivot, slide or swivel in such a way that on a turn of the chain link type pinion by 180° the toothed segment and this the devices are changed in their working position displaced by a tooth distance and the chain link type pinions are moved backwards and forwards during this by a half tooth distance.
