SÅELEMENT OG SÅMASKINE

Systems and methods for distributing granular products onto or into the soil, comprising a chassis, a first assembly for distributing a first granular product comprising a main hopper, fixed to a frame, which can move in relation to said chassis and is able to adopt a position known as the "lowered" position, which is the working position of said sowing unit, and a position known as the "raised" position, which is the maintenance position of said sowing unit, and that is able to move from said "lowered" position to said "raised" position and vice versa, said sowing unit also comprising a mechanism for tilting said frame and comprising a collapsible quadrangle or double quadrangle that connects said frame to said chassis, said tilting mechanism being arranged substantially perpendicular to the plane X-X′ formed by said chassis, and maintained substantially perpendicular to said plane X-X′ in said "lowered" and "raised" positions and when moving from one position to the other, and vice versa. The systems may include a seed drill comprising one or more sowing units.
