ABSTRACT:
An implement has rows of tines on carrier supports that are elongated and extend transverse to the direction of travel. A transmission shaft with pairs of eccentrics is positioned between the supports and connected to move the tines of the supports to and fro in relatively opposite directions. The eccentrics are in pairs and interconnected to the frame by adjustable links that control the operative movements of the tines, those movements being in the direction of travel. A pulverizing member is pivoted to the rear carrier support to move with same and a front soil levelling member with strip-shaped members is positioned in front of the tines. Preferably, a supporting roller is connected to the frame at the rear of the pulverizing member.
