An autonomous agricultural carrier vehicle, for carrying an agricultural implement includes a chassis with steerable wheels or tracks attached to a frame, wherein the frame includes a mounting apparatus for connection to the agricultural implement. The vehicle further includes an environmental sensor system for determining obstacles or elements present in the vicinity of the carrier vehicle and a control device for controlling the carrier vehicle or the at least one implement, wherein the control device is connected to a position determination system that captures and issues a position to create an autonomous agricultural carrier vehicle with which the impact force is not reduced. No additional tractor vehicle is needed for the implement and no operator is necessary during field work, wherein it is provided that position-dependent working instructions for the carrier vehicle are preferably stored in the control device.

A system and method for determining the optimal machine working direction(s) of travel for a field boundary to be used in a guidance/navigation system for machine control includes, using specific field boundary information and machine specific information to spatially simulate travel path estimates over a plurality of splayed working directions of travel to determine the optimal working direction(s) of travel for the field boundary. Optimizing the spatial field efficiency by simulating travel path estimates to select an optimal working direction(s) of travel may then be used in accordance with a machine's guidance and/or navigation system, via an information transfer system, as the reference working direction(s) of travel for the machine to guide and control itself while performing fieldwork.

A vertical tilling implement to be pulled behind and agricultural vehicle having a number of gangs of fluted-concave disc blades, rolling baskets, and wheels connected to a main frame. As the vertical tilling implement is pulled, the fluted-concave disc blades move the soil in a direction lateral to the side of the blades as well as up. Meanwhile, the rolling bars aid in leveling the seedbed and crushing the remaining large pieces of soil. The vertical tilling implement reduces the amount of subsoil compaction and cuts through heavy residue making it ideal for use in the fall or in the spring.
