A suspension for a row cleaner associated with a furrow opener in a seedi ng machine includes a lifting mechanism to lift the row cleaner when the furrow opener is lifted. The lifting mechanism includes a bell crank having an input crank arm coupled to the furrow opener by a fist linkage to rotate the bell crank when the furrow opener is lifted. An output crank arm of the bell crank is coupled to the row cleaner by a second linkage to lift the row cleaner when the bell crank shaf t is rotated by lifting of the furrow opener. The second linkage is flexible, suc h as a rope, to enable the row cleaner to lift to avoid obstacles without back driving th e bell crank to also lift the furrow opener. The flexible second linkage also enables the row cleaner to be equipped with a lock to retain the row cleaner in a raised position for ase of the seeding machine in conditions not requiring a row cleaner.</SDOAB >
