ABSTRACT:
Apparatus for loosening soil as it moves over the surface of a field, has a cross-beam and a linkage for connecting the cross-beam to a vehicle, such as a farm tractor, for towing the apparatus over the ground. The cross-beam extends in a direction transverse to the direction of travel and supports a drive shaft having an axis of rotation parallel to the axis of the cross-beam. The drive shaft is connected to the power output of the tractor for rotating the drive shaft as the tractor is advanced. A plurality of discs are spaced along and eccentrically mounted on the drive shaft for eccentric rotation. A swing lever is suspended from each of the discs and a loosening bit is removably carried by each swing lever. Each loosening bit has a transversely extending arrow-shaped blade at the lower end for engaging and loosening the soil. A guide rod is connected between each swing lever and the cross-beam. Accordingly, the swing levers are caused to swing in a plane parallel to the direction of travel and the guide rods restrain the swinging movement to cause the point on the arrow-shaped blade to describe a closed non-circular arcuate path.
