A system for wirelessly monitoring the operational status of ground-engaging tools includes an attachment structure, a ground-engaging tool pivotably coupled to the attachment structure at a pivot point, and a shear pin at least partially extending through both the attachment structure and ground-engaging tool. In addition, the system includes a conductive member extending within the shear pin to form an electrical circuit therein, and a wireless circuit monitor coupled to the conductive member such that the circuit monitor is configured to detect a circuit parameter associated with the electrical circuit. Moreover, the system includes an antenna configured to receive data transmitted wirelessly from the circuit monitor that is indicative of the circuit parameter, and a controller configured to monitor the data received by the antenna and identify a change in a working condition of the shear pin based on a detected variation in the data.

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.

In one aspect, a system for detecting tripping of ground engaging tools on an agricultural implement may include a ground engaging tool coupled to an implement frame. Furthermore, the system may include a motion sensor installed on the implement frame, with the motion sensor configured to capture data indicative of motion of the implement frame. Moreover, the system may include a controller configured to monitor the motion of the implement frame based on the data received from the motion sensor. In addition, the controller may be further configured to determine when the ground engaging tool has tripped based on the monitored motion.

An implement for tilling the soil and methods of using the same. The implement may include cultivator sweeps arranged in staggered rows, trailing coulters positioned behind a rearmost row of the cultivator sweeps, and a finishing attachment positioned proximate the trailing coulters. The trailing coulters are designed to penetrate deeper into the soil than the cultivator sweeps. The method includes passing such an implement through the soil such that the trailing coulters pass through the soil after the sweeps and the finishing attachment passes over and/or through the soil.

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.
