The invention relates to a system for conveying an agricultural formulation, comprising a container (1) for receiving the agricultural formulation, said container (1) having a removal opening (19), and a conveyor unit (2) which is secured rigidly in or on the container (1) for conveying the agricultural formulation located in the container (1) through the removal opening (19). The system further comprises a drive unit which is coupled to the conveyor unit (2) so as to be releasable separately therefrom in order to drive the conveyor unit (2). The drive unit has a hydraulic unit (12), which has a cylinder chamber (9), a piston (20) that can be moved back and forth in the cylinder chamber (9), and an outlet opening (22) for a hydraulic liquid, and a hydraulic line (8), which is coupled to the outlet opening (22) and can be coupled to the conveyor unit (2). The system according to the invention is characterized in that the hydraulic liquid is water or is quickly biodegradable. Furthermore, the hydraulic unit has an additional cylinder chamber for driving the piston using another hydraulic liquid. The invention further relates to a method for conveying an agricultural formulation.
