The invention relates to an apparatus for separating out grains of seed, fertilizer or the like, having a separating device (1) that works on the overpressure principle. The separating device (1) has the following: a housing (2), which is formed with a housing base (3) to be mounted on a frame or on a drill row of an agricultural machine and with a housing cover (30, 4), which is arranged on the housing base (3) in a releasable manner for opening and closing a housing interior (14); a grain sump (19), which is designed to receive grains of seed, fertilizer or the like that have been introduced into the housing interior (14) and are to be separated out; a separating disc, which is mounted in a rotatable manner in the housing interior (14) and has an arrangement of openings; an overpressure region, which is formable in the housing cover (30, 4) on a front side of the separating disc during operation, such that a flow is formable from the overpressure region through the openings to the rear side of the separating disc and grains separated as a result are able to be localized in the region of the openings or adjacently thereto; and a grain transfer device (10), which is formed with a feed (15), a wall bushing (20) and an outlet (21) at the housing cover (30, 4), wherein the separated grains, after being detached from the separating disc, can be introduced through the feed (15) into the wall bushing (20) and be discharged from the housing interior (14) through said wall bushing (20) via the outlet (21). Furthermore, a seed meter and a drill row, and a method for separating out grains of seed, fertilizer or the like by means of a separating device (1) that works on the overpressure principle are disclosed.

A distributor head of a distribution agricultural device comprises an outer hoop provided with at least four outlets of the same size, arranged evenly along the circumference of the outer hoop, a movably positioned ring, a main inlet, and a driving mechanism connected with the ring through a ring attachment, wherein the ring is provided with a number of evenly arranged openings of the same size, number of which corresponds to half of the number of outlets. The ring can be in three operating positions, wherein in the first position, the ring is located in the same plane as the outer hoop and therefore covers every other outlet, in the second position it is not located in the same plane as the outer hoop and thus does not cover any outlet, and in the third position it is located in the same plane as the outer hoop and thus covers every other outlet, wherein the outlets covered in the third position are different from the outlets covered in the first position of the ring.

An agricultural implement comprises a container mounted on a frame arranged for movement across an agricultural field, which container is suited for storing a granular product to be deposited across the field. The agricultural implement additionally including a metering system arranged for metering the granular product in movement from a product exit of the container to a product discharge, typically in operative communication with a pneumatic conveying system, for eventual delivery to the agricultural field. The agricultural implement features a crushing system arranged for reducing a size of the granular product that is disposed in series with the metering system so as to be located between the product exit and the product discharge, such that metered quantities of the crushed granular product can be deposited into the ground as the agricultural implement is displaced in the forward working direction across the field.
