A towed sowing machine comprises a frame, a tow bar, shoes mounted on the frame, a chain weeding harrow and a chassis with running wheels, the chassis is behind the shoes before the chain weeding harrow, said harrow is mounted on the frame in a lifting apparatus adapted for lifting and rests upon the ground in the working position via depth guiding elements. To design a sowing machine with a chain weeding harrow capable to change the height relative to the ground surface, it is provided that in the working position the chain weeding harrow is lifted using the lifting apparatus cooperating with the supporting elements, and thus, lifted relative the ground surface via the running wheels. |
