Closed appliance combination for agriculture, consisting of a ground-working combination which has at least one ground-working appliance with at least one ground roller arranged behind the ground-working implements of the ground-working appliance, and of a seed drill with seed coulters, which is connected to the ground-working combination by coupling devices and which is semi-mounted on the ground-working combination. In order to improve the known appliance combinations in such a way that, with a seed drill semi-mounted on a ground-working combination, damage to the seed coulters during reversal at the field end when the implement combination can be lifted out only to some extent is prevented in a simple way, without the supply container being pivoted or raised, provision is made for the seed coulters (9) to be arranged so as to be movable upwards relative to the ground-working combination (1) and to the frame of the seed drill (2), and for there to be connected to the seed coulters (9) a central hydraulic or electrical lifting-out device (15), by means of which the seed coulters (9) can be moved upwards jointly or be lowered downwards jointly. <IMAGE>
