A ground-working tool including a shank and a sub-soil point at the bottom end of the shank. The sub-soil point has a leading cutting edge transverse to and in front of the longitudinal axis of the shank, a back portion behind the shank, a top portion from the leading edge to the shank, a bottom portion, and opposite lateral sides. A soil-rolling surface on at least one of the opposite lateral sides of the sub-soil point, each soil-rolling surface being concave in cross-section between top and bottom edges along a front to back length.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

An agricultural system includes a frame, a cutter bar assembly configured to move relative to the frame during an operation of the agricultural system, a reel assembly configured to guide crops to the cutter bar assembly during the operation of the agricultural system, and a controller. The controller is configured to receive feedback indicative of a profile of the cutter bar assembly, set a position boundary of the reel assembly based on the feedback, and block movement of the reel assembly to a position beyond the position boundary of the reel assembly.

A walk-behind tractor has an increased ground clearance to define a plant receiving space that has a greater height than a conventional walk-behind tractor having a straight axle. The walk-behind tractor has trailing drop arms from a frame that carry wheel axles that result in an elevated height of a driveshaft. The elevated driveshaft increases the ground clearance for taller plants to pass therebeneath during operation of the walk-behind tractor which would otherwise be too tall to pass below a conventional straight axle walk-behind tractor.

In one aspect, a system for controlling ground-engaging tools of an agricultural implement may include first and second ground-engaging tools configured to perform first and second operations, respectively, on a field as the agricultural implement is moved across the field. Furthermore, a controller of the disclosed system may be configured to determine a first value of a field characteristic based on the received sensor data and adjust an operating parameter of the first ground-engaging tool based on the determined first value. After adjusting the operating parameter of the first ground-engaging tool, the controller may be configured to determine a second value of the field characteristic based on the sensor data and adjust an operating parameter of the second ground-engaging tool based on the determined second value.

An agricultural vehicle header having a center section, a wing section, a hinge connecting the center section's lower frame to the wing section's lower frame, and a torque transfer linkage connecting the center section's upper frame to the wing section's upper frame. The torque transfer link has a first link, a second link, a first pivot connection joining the first link to the center section upper frame, and providing a respective single degree of rotational freedom between the first link and the center section upper frame, a second pivot connection joining the first link to the second link, and providing a respective single degree of rotational freedom between the first link and the second link, and a third pivot connection joining the second link to the first wing section upper frame, and providing a respective single degree of rotational freedom between the second link and the first wing section frame.

A method for planning the cultivation of an at least quadrangular area of an agricultural field is presented. The area has edge sections between its corners, including a first edge section and a second edge section. The second edge section is arranged opposite of and oblique to the first edge section. A plurality of first working paths and a plurality of second working paths are determined. A lane that runs at least partially along the first working paths and the second working paths and along which an agricultural machine is to be moved over the area is determined. A plurality of turning points along the lane at which the machine is steered is determined, such that the lane runs less along the first working paths and further along the second working paths as the distance from the first edge section increases.

An implement frame having a carriage frame for coupling to a towing vehicle and wheels to support the frame for movement over a ground surface. A pivot frame is rotationally mounted to the carriage frame and a lift assembly is coupled to the pivot frame via a shift assembly. A tool bar is mounted to the lift assembly. The shift assembly moves the tool bar forward as it is moved from the field use position to the transport position. The wheels are mounted to swing arms to move the wheels inward for a narrow transport position.

An attachment device, in particular a milling machine and/or a mulcher, for use with a carrier vehicle, includes at least one functional unit which is configured for a supply of energy by way of the carrier vehicle, in order to achieve rapid and/or simple initial start-up, the attachment device has at least one control unit which, in at least one operating state, automatically controls and/or regulates at least one limit value of an operating parameter of the functional unit.

The present invention provides a closing wheel frame assembly comprising a closing wheel frame, a closing wheel assembly, and a lever arm adjustment assembly. A retaining pin secures a lever arm in a desired position to set an angle or orientation of the closing wheel assembly relative to the frame, seed furrow (trench or trough), or soil surface. Operation of the lever arm changes the angle or orientation of the closing wheel assembly relative to the frame, seed furrow (trench or trough), or soil surface.
