ABSTRACT:
An agricultural implement has a driven rotor with cultivator blades and a hood that overlies the rotor. The hood extends down to the rear and the lower hood portion is a guide that has a row of teeth. The teeth are extensions that furrow the worked soil and each tooth corresponds to a material delivery duct that communicates material, such as seeds, from a hopper to the furrows. A ground engaging trough-like levelling member is adjustably connected to side plates of the hood and the openings of the ducts are positioned near the levelling member to prevent clogging of the openings. One or more rear rollers are arranged behind the levelling member with driving connections to a rotatable mechanism in the hopper.
