| The invention refers to a joint device at an agricultural machine with at least one tool- bearing beam (2a - c, 3a - c) for soil tillage tools (4, 5, 38, 39), such as seed coulters and cultivator tines, whereby a portion (10) of the beam end, at least on one side of the machine, is detachably fastened by means of a bolt/nut connection (13, 18, 23) arranged within said tool-bearing beam. A threaded body (18, 50) in the bolt/nut connection is fixed, preferably plug welded, in the main part of the beam (2a - c, 3a - c). | ||||||

| A drawbar for finishing attachments is arranged to attach to a fore-aft frame member of a tillage implement. The drawbar has a saddle with spaced apart side walls defining a channel configured to receive the frame member. When the frame member is received in the channel, the side walls of the saddle overlap side walls of the frame member and extend in the fore-aft direction rearward of an end of the frame member. The side walls of the saddle and the frame member have mounting openings that align along a lateral direction transverse to the fore-aft direction. | ||||||

| A tillage implement has a main frame, a hinged wing and a plurality of gangs each having tools along its length. The plurality of gangs includes a main frame gang mounted to the main frame and inner and outer wing gangs mounted to the wing. The inner and outer wing gangs have inner ends that are forward or rearward with respect to the direction of travel of outer ends, and the lengths of the inner and outer wing gangs are offset from each other in the direction of travel. | ||||||

| Representative implementations of devices and techniques provide a tool bar comprising a structure having a plurality of sections arranged in geometric forms. The geometric forms may change shape to keep a tool that is attached to the structure in a desired position while the tool bar is being used on uneven terrain, such as on a hillside or while the tool bar is rotated or pivoted at an angle with respect to the direction of travel. Changing the shape of the geometric forms can also result in rotating the tool attached to the structure with respect to the tool bar. | ||||||

| A tool supporting bar comprising an elongated tubular perimeter wall defining an interior and including first and second perimeter wall portions. Each perimeter wall portion includes a first side wall portion and sections of two other side wall portions each extending from the first side wall portion. Each perimeter wall portion may be substantially U-shaped and positioned in opposition to each other, with the two perimeter wall portions being connected together. At least one reinforcing wall may be located in the interior and attached to the first side wall portion of one of the perimeter wall portions. Embodiments with the reinforcing wall attached to the exterior of the perimeter wall are also described. | ||||||

| A multisection tandem disk harrow has a frame, a first disk gang, and a second disk gang. The concave sides of the disk blades in the first disk gang face one side of the disk harrow, and the concave sides of the disk blades in the second disk gang face the other side of the disk harrow. The disk blades in the first disk gang are mounted for rotation about a common axis that extends through a center of the disk blades. The disk blades in the second disk gang are mounted for rotation about respective individual axes that are substantially parallel with and spaced apart from each other. The first and second disk gangs are arranged so that the common axis of the first disk gang is nonparallel with the individual axes of the second disk gang. Various frame, support wheels, disk gang, and hitch configurations are also disclosed. | ||||||
