Abstract: An agricultural machine (101; 201; 301) comprising two mainly parallel, in the direction of travel, cross-running disc implement rows (102a, 102c; 202a, 202b; 304a, 304b), wherein the orientation of the disc implements (102b, 102d; 203a, 203b; 302a, 302b) contained in the mentioned disc implement rows is arranged so that the fore row (102a; 202a; 304a) has disc implements that are mounted on a frame beam (110; 211; 303) and that are angled outwards and backwards towards the sides of the machine and in a dividing line mainly parallel to the direction of travel of the machine form a first point of change (208a, 304c), and the rear row (102c, 202b; 304b) has disc implements (102d; 203b; 302b) that are mounted on a frame beam (110; 211; 303) and that are angled inwards and backwards from the sides of the machine and in the dividing line form a second point of change (208b, 304a), wherein the fore row is adapted to throw soil from the first point of change outwards towards the sides of the machine and the other ro

Abstract: A wheel track closing device is mounted on a tractor for closing the wheel tracks formed by self-propelled irrigation systems. A first soil mover is positioned at the front of the tractor and moves soil laterally to the wheel track from one side thereof, with the soil being moved thereinto being compacted by the right front wheel of the tractor. A second soil mover is mounted at the right side of the tractor between the right front wheel and the right rear wheel and moves soil, from the other side of the wheel track, into the track with the soil that has been moved into the wheel track being compacted by the right rear wheel of the tractor.

Abstract: An implement having a frame adapted to be transported in earth traversing movement along a predetermined path of travel; a first earth working tool mounted on the frame disposed for engagement with the earth during such earth traversing movement and operable to move earth laterally of the path of travel; a second earth working tool mounted on the frame forwardly of the first earth working tool relative to the path of travel disposed for engagement with the earth during the earth traversing movement and operable to move earth laterally of the path of travel; and a third earth working tool mounted on the frame rearwardly of the first earth working tool relative to the path of travel and disposed for engagement with the earth during such earth traversing movement and operable to move earth laterally of the path of travel and wherein the directions of movement of the earth laterally of the path of travel by the first, second and third earth working tools is such as to work the earth substantially evenly and to re

Abstract: This is a machine for forming V-ditches for the irrigation of soil. The machine consists of a central frame with a two wheel carriage and plows of subassemblies. Each plow consists of a right subassembly and a left subassembly universally connected to the right and left sides respectively of the central frame. Each plow forms an acute horizontal angle with the central frame. The acute angle is fixed by the use of chains, having one part adjacent to an end attached to the central frame and another part of the chain adjacent to the opposite end, attached to the extended end of the subassembly. Each subassembly contains concavo-convex rotatable discs mounted parallel to each other on a common axle. The discs are assembled so that the concave side of the discs penetrate the soil when the machine is moved forward by a suitable draft device.

Abstract: An agricultural implement for tilling soil employing three disc gang assemblies pivotally mounted in spaced apart relationship to a support frame assembly having a hitch mechanism associated therewith for coupling to a conventional towing vehicle, the disc gang assemblies being arranged such that the front and rear disc gang assemblies are approximately equidistantly spaced from the center disc gang assembly and are offset laterally from the longitudinal axis of the support frame assembly, each of the disc gang assemblies including a plurality of spaced discing tools positioned such that the lateral working width of the center disc gang assembly is approximately equal to the combined lateral working width of the front and rear disc gang assemblies.
