| An autonomous farm vehicle is provided. In a preferred embodiment the vehicle is a plow, which is capable of driving itself without input from an operator. The plow is significantly lighter in weight and smaller in size then a combined tractor and plow, and can be operated continuously. The vehicle, includes a chassis mounted on a plurality of wheels and a tool in the form of a plowing assembly mounted to the chassis and displaceable about the chassis between a first and a second position, such that in the first position the plowing assembly is operational while the vehicle is driven in a first direction. In the second position the plowing assembly is operational while the vehicle is driven in a second direction substantially opposite to the first direction. | ||||||

| A fastening arrangement is provided for attaching a row unit to the tool bar of an agricultural implement. The fastening arrangement includes an elongated flat operatively connected to the tool bar. The elongated fiat has a leading surface lying in a first plane nonadjacent to a second plane which includes a trailing surface of the tool bar. A head bracket is adapted to receive a row unit. The head bracket has an aperture therethough and is supportable on the elongated flat. A clamping nut and bolt combination is configured to fasten the head bracket to the elongated flat. The clamping nut and bolt combination including a bolt adapted to pass through the aperture of the head bracket engage the clamping nut in a mating relationship. | ||||||

| The selective positioning of row units along a planter tool bar is facilitated by introducing an elongated channel of generally C-shaped cross-sectional configuration intermediate the tool bar and a plurality of row unit head brackets. The channel is welded or otherwise fixed to the tool bar with the open edge of the “C” facing away from the tool bar and the head brackets are fixed to the channel by clamping nut and bolt assemblies. The bolts extend through the clamping brackets and engage corresponding clamping nuts. The clamping nuts are positioned within the “C” and may be slid along the inner edge of the channel to any preferred position. The bolts are then and tightened fixing the head bracket at the selected at location. | ||||||

| An agricultural machine for working soil or for sowing seeds, including a trailed chassis and work elements distributed on a longitudinal bar in plural sections, the longitudinal bar including at least two primary beams extending substantially transversely to a direction of advance in a work configuration. A secondary beam is connected to each primary beam by two connection devices, the secondary beams support the work elements, and each secondary beam rests on the soil by two support wheels and is configured to move freely during work to follow a profile of the terrain. | ||||||
