Abstract

A combination is made up of a tractor and a seeder suitable for direct drilling mounted on a three-point hitch of the tractor. The seeder has a crossbeam that is connected to the three-point hitch and on which a plurality of sowing units are arranged laterally in succession. The sowing units, each equipped with at least one furrow opener, are respectively prestressed downward in relation to the crossbeam by an actuator, and the three-point hitch can be self-locked in relation to a chassis of the tractor. During the sowing operation, the pressing forces for the furrow openers are therefore introduced via the sowing units, the actuator, the crossbeam and the three-point hitch into the chassis of the tractor.
