The seed drill is one which additionally includes structure making it possible, as soon as the planting elements leave the earth, to align the rear chassis with respect to the front chassis. The object of the present invention is to avoid any possible shocks between the rear chassis and the front chassis, the shocks being caused by pivoting of the rear chassis about the central articulation when the seed drill is switched to the transport position on sloping ground.
