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.

This present disclosure relates to an earthworking tine and method of manufacture. More particularly the disclosure is directed to a earthworking tine with a hardened end and related methods. Specifically, the disclosure relates to an earthworking tine with an indicator layer to indicate wear and potential tine failure before failure occurs.

In one aspect, a shank assembly for an agricultural implement may include a shank and a biasing element configured to exert a biasing force on the shank. The shank assembly may also include a reversible mounting plate defining a mounting aperture offset from a centerline of the reversible mounting plate such that a position of a second mounting location of the biasing element relative to a first mounting location of the biasing element differs depending on whether the reversible mounting plate is provided in a first orientation relative to the biasing element or a second orientation relative to the biasing element. The biasing element may exert a first biasing force on the shank when the reversible member is oriented in the first orientation and a second, different biasing force on the shank when the reversible member is oriented in the second orientation.

An agricultural implement includes a shank assembly having a ground-engaging shank. Furthermore, the shank assembly includes a biasing element coupled to a frame of the agricultural implement via a first pivot joint and coupled to the ground-engaging shank via a second pivot joint. Additionally, the agricultural implement includes a load sensor(s) configured to generate data indicative of the load(s) being applied to the first and second pivot joints by the biasing element. In addition, the agricultural implement includes a computing system configured to determine when the ground-engaging shank is tripping or floating based on the data generated by the load sensor(s).

A system for monitoring the operational status of shear pins for ground-engaging assemblies of agricultural implements includes a ground-engaging assembly including an attachment structure pivotably coupling the ground-engaging assembly to a frame of an agricultural implement, a ground-engaging tool pivotably coupled to the attachment structure at a pivot joint, and a shear pin at least partially extending through the attachment structure and the ground-engaging tool to prevent pivoting of the ground-engaging tool about the pivot joint. The system also includes an orientation sensor configured to generate data indicative of an orientation of the attachment structure, and a computing system communicatively coupled to the orientation sensor. The computing system is configured to monitor the orientation of the attachment structure and determine a change in an operational status of the shear pin based on detected changes in the monitored orientation of the attachment structure.
