ABSTRACT:
A drive transmission for a soil working implement includes spaced apart elongated tined beams that extend horizontally transverse to the direction of implement travel. The beams are driven to move vertically and horizontally through generally circular paths so that the tines are raised and lowered while moving laterally of the travel direction. A driving shaft and a driven shaft are spaced apart and extend perpendicular to the beams and above same. Each shaft mounts a respective eccentric disc that is fixed to each beam and an imput is connected to rotate the driving shaft which, in turn, rotates the driven shaft via the eccentric discs. The beams are connected to be displaced out-of-phase to mitigate vibration.
