An agricultural implement has a closing disk assembly for closing furrows along a section of ground. The closing disk assembly has a pair of closing disks attached to opposite sides and opposite ends of a walking beam. The closing disks are offset from a reference plane of the closing disk assembly. The walking beam is rotatably coupled to the closing disk assembly through a rocker assembly, a support arm, and a mounting assembly. The walking beam may rotate relative to the rocker assembly to account for variations in the angle of the ground relative to the disks.

A system for controlling an implement during a tillage operation may include a frame and a ground-engaging tool pivotally coupled to the frame and movable relative to the frame between a retracted position and an extended position. An actuator may be configured to bias the ground-engaging tool towards the extended position during the tillage operation. An adjustable valve may be configured to permit flow out of the actuator when a fluid pressure of the actuator exceeds a reset pressure such that the actuator allows the ground-engaging tool to pivot towards the retracted position. A controller may be configured to determine at least one of an actuator position or a load value indicative of a force applied by the ground-engaging tool against the soil during the tillage operation and adjust the reset pressure based on the at least one of the actuator position or the load value.

The invention relates to a utensil (1) for agricultural working provided with two main elements, a work tool (2) and a support element (3), made so as to be couplable to each other by means of a fastening device (4). Such device (4) is received in an opening (5) made on the support element (3) and in abutment surfaces (60, 61) which are made on the work tool (2); said abutment surfaces (60, 61) advantageously are shaped so that the tool (2) can be coupled and locked with the support element (3) according to whether the device (4) abuts with one of the ends thereof with one or with the other of the two abutment surfaces (60, 61).

A soil cultivator comprises a frame attachable to a tractor and at least one processing unit attached to the frame. The processing unit has a frame-like element, a first soil cultivation tool attached to the frame-like element via a first connecting element, a second soil cultivation tool attached to the frame-like element via a second connecting element, and a swiveling axis element. The first soil cultivation tool and the second soil cultivation tool are arranged on different sides of the swiveling axis element. The first connecting element has a first annular section, and the second connecting element has a second annular section. The first and the second connecting elements are arranged so that they can swivel around the swiveling axis element such that a change in the extent of the frame-like element can effect a change in the distance between the first and the second soil cultivation tools.

A multi-positional stalk stomper assembly for attaching a stalk stomper to a toolbar of a farm implement comprises a mounting bracket and a pivotal shoe assembly. The mounting bracket is adaptable to be attached to the toolbar of the farm implement and includes a rectangular plate, the plate having first and second major sides, the first side engageable with the toolbar. A first connecting member outwardly extends perpendicular from the second major side of the plate. The shoe assembly includes a torsion spring assembly, a second connecting member outwardly extending from the torsion spring assembly, the second connecting member mateable with the first connecting member, a shoe bracket pivotally connected to the torsion spring assembly, and a downwardly extending shoe attached to the shoe bracket. Upon mating the second connecting member with the first connecting member, the shoe assembly is lockable to the mounting bracket at a selected position.

The invention relates to a soil-working device having a support frame (11), on which harrow tines (17) are arranged, which are preloaded by means of spring systems (18), the preload being centrally adjustable by means of a hydraulic cylinder (21). The harrow tines (17) are designed as two-armed levers, and the entire adjustment mechanism consisting of hydraulic cylinder (21), transverse bar (22), longitudinal bars (23), levers (19), and spring systems (18) is arranged above the fulcrums of the harrow tines (17). Thus, nearly only the harrow times (17) are located in the space below the fulcrums of the harrow tines (17). In addition, the harrow tines (17) can be not only pressed downward but also raised by means of the adjustment mechanism.
