ABSTRACT:
A cultivating implement has a supporting frame and elongated tined beams, extending transverse to the direction of travel, located below the frame. Each tined beam is connected to respective eccentric mechanisms mounted on two rotatable shafts that extend in the direction of travel and the shafts are supported on frame beams. One of the shafts is connected to a driving shaft via a gear box that houses a step-up gear transmission and drives the other shaft via the beams. The tined beams are moved through circular paths out of phase with respect to one another and can mount tines that crumble soil or strip-shaped tines that cut vegetation. A supporting roller is adjustably mounted on the frame to trail the tines and further work the soil.
