ABSTRACT:
An implement has two elongated tined carriers that extend transverse to the direction of travel. The carriers are moved through circular orbits around spaced apart driving shafts that extend upwardly. An eccentric for each carrier is journalled to each shaft and includes a disc with encircling ring having support plates that are bolted to the respective carrier. The upper eccentrics extend forwardly from a drive shaft, located between the carriers, to the forward carrier and the lower eccentrics extend rearwardly to the trailing carrier. The carriers are off set relative to one another as well as out-of-phase. An elongated levelling beam is adjustably connected to the forward carrier and a supporting roller is connected to the frame at the rear of the trailing carrier.
