<p>The seed sowing machine is constructed on a towed chassis (53), which carries the reference elements (17), by pivots (10), which allow vertical movement from the transport position into the working position. The seeding mechanism (56) is supported by a carrying structure (61), which is linked to the chassis by similar pivots (81). In the working position, devices (86,88) are fitted to limit the displacements of the reference elements and the carrying structure respectively.</p> |
