A laterally movable carrier is associated with a row frame. The carrier is connected to a frame member, an opener, a first outlet and a second outlet to allow for dynamically variable adjustment of the lateral separation between a first row of planted seed and a second row of planted seed, where the first row of seed is adjacent to the second row of seed.

A system for measuring soil electrical conductivity having a support, a plurality of soil engaging contacts (e.g. coulters) mounted to the support, at least one probe, and a processor. Current is provided through the soil and then measured. The voltages measured between respective opposed pairs of contacts are used to calculate the soil electrical conductivity of the soil within first, second, and third depth ranges. Each probe is selectively inserted within the soil and is configured to determine the soil electrical conductivity of the soil within the first, second, and third depth ranges. The processor correlates the calculated soil electrical conductivity of the soil within the first, second, and third depth ranges with the soil electrical conductivity determinations of the probe. Methods of determining and imaging soil characteristics and applying those characteristics to a crop model are included.

Cutting element made of cemented carbide for an agricultural soil cultivation tool for cutting into the earth, which includes a top side and a bottom side, a front side, a back side opposite of the front side, and at least one lateral surface. The top and bottom sides are connected via the front side, back side, and the at least one lateral surface. The front side includes a cutting region having multiple teeth, and at least one tooth is formed with a first flank and a second flank. To achieve an efficient cutting into the earth with a complete cut through the weeds or herbaceous plants present in the earth, a profile line of the first flank and a profile line of the second flank have different lengths. In this manner, weeds are completely severed and killed, whereby use of sprays for killing weeds is reduced to protect the environment.

Disclosed is a sowing coulter arrangement comprising a suspension device for mounting the sowing coulter arrangement on a machine frame; a coulter frame connected to the suspension device for mounting components of the sowing coulter arrangement thereon; and a coulter disk. The arrangement further comprises a furrow closer pivotally mounted on the coulter frame; a metering device for dispensing the material to be distributed; a seed tube for transporting the material to be distributed from the metering device to a seed furrow; and a catching element for catching the material disposed downstream of the outlet of the seed tube. The metering device, the seed tube, and the catching element form a unit and are mounted on a carrier that is pivotably affixed to the coulter frame, whereby an arrangement of an outlet of a seed tube in relation to a catching element is at all times kept largely constant.

A coulter disc mounting assembly for a tillage implement supports a coulter disc thereon to be angularly offset from the forward working direction of the implement. The tillage implement typically includes a frame supporting a plurality of tool shanks thereon, each having a mounting surface adapted for mounting a respective shovel opener thereon in which the mounting surface has a width which is substantially perpendicular to the forward working direction. The disc mounting assembly has a hub with a mounting surface for fastening against the mounting surface of one of the tool shanks in which the hub supports a coulter disc thereon such that the coulter axis is oriented non-perpendicularly to the forward working direction.

A double disc coulter 1 has two disc coulters 2 angled to each other to form a V shape that are rotatable on hollow axle stubs 3 by means of bearing units 18. One hollow axle stub 3 is arranged with a flange face 5 facing the coulter bar 4 at an angle to the vertical plane of the rotation axis of the hollow axle stubs. At the same time, the hollow axle stub 3 determines the angular position of the plane 13 that intersects in the rotation axis 6 and in an axis 7 vertical to the flange face 8, 9 of the coulter bar 4.
