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.

A disk assembly for agricultural implements comprises a disk hanger including a proximal end and a distal end opposite the proximal end. The disk assembly further includes a hanger spindle supported relative to the distal end of the disk hanger for rotation about a first axis of rotation, and a blade spindle supported relative to the hanger spindle, with the blade spindle being rotatable about a second axis of rotation oriented non-parallel relative to the first axis of rotation. Additionally, the disk assembly includes a blade coupled to the blade spindle for rotation therewith about the second axis of rotation. Moreover, the disk assembly is configured such that rotation of the hanger spindle relative to the disk hanger about the first axis of rotation results in an adjustment of both an angle-of-engagement and a camber angle of the blade.

A system for managing material accumulation relative to ground engaging tools of an agricultural implement may include a ground engaging tool and an acoustic sensor configured to generate data indicative of an acoustic parameter of a sound produced as the ground engaging tool engages the ground when a ground engaging operation is performed within a field. Additionally, the system may include a controller communicatively coupled to the acoustic sensor. The controller may be configured to monitor the data received from the acoustic sensor and determine a presence of material accumulation relative to the ground engaging tool based at least in part on the acoustic parameter.

An agricultural implement (1) for soil working, comprising a frame (10, 101, 10a, 10b, 10c, 10d, 10e), a number of ground-engaging tools (12, 13) carried by the frame, at least one rolling ground support (11a, 11b), the height position of which is adjustable relative to the frame, a height sensor (31) for contact-free measuring of the height position of the frame relative to a ground surface (G1), and a control unit (15), arranged to receive a signal from the height sensor (31) and to control the height position of the rolling ground support (11a, 11b). At least one of the tools (12, 13) is resilient relative to the frame (10, 101, 10a, 10b, 10c, 10d, 10e). A tool position sensor (32) is arranged to measure the orientation of the tool (12, 13), and the control unit (15) is arranged to receive a signal from the tool position sensor (32) and to calculate a work depth for said tool (12, 13) based on the signal from the height sensor (31) and based on the signal from the tool position sensor (32). Furthermore, a method of determining the work depth of a soil-working agricultural implement is shown.

The present disclosure provides systems and methods that measure crop residue in a field from imagery of the field. In particular, the present subject matter is directed to systems and methods that include or otherwise leverage a machine-learned crop residue classification model to determine a crop residue parameter value for a portion of a field based at least in part on imagery of such portion of the field captured by an imaging device. For example, the imaging device can be a camera positioned in a downward-facing direction and physically coupled to a work vehicle or an implement towed by the work vehicle through the field.

In one aspect, a system for de-plugging an agricultural implement may include an actuator coupled between a ground-engaging tool of the implement and a frame of the implement. The actuator maybe configured to move the ground-engaging tool relative to the frame between a first position in which the tool penetrates the soil and a second position in which the tool is lifted out of the soil. Furthermore, the system may include a sensor configured to capture data indicative of plugging of the ground-engaging tool. Additionally, a controller of the disclosed system may be configured to determine when the ground-engaging tool is plugged based on the data received from the sensor. Moreover, the controller may be further configured to control an operation of the actuator such that the ground-engaging tool is moved from the first position to the second position when it is determined that the tool is plugged.

A harrow has a frame, tines pivotal on the frame and each a lower arm with a soil surface under the harrow. An actuator on the frame can shift a bar frame shiftable horizontally on the frame. Respective spring biasing units above the axes each have a guide element connected to the bar frame and displaceable therewith through a predetermined displacement path, a connecting element connected to respective upper arms of the tines, a first compression spring bearing on both of the elements and biasing the other element away from the one element so as to press the lower arm downward into the soil surface during movement of the respective guide element through the path, and a second compression spring bearing continuously on one of the elements and engageable with the other of the elements after displacement of the respective spring-biasing unit only through a part of the path.
