An agricultural tilling assembly has an elongate structure, and at least one ground engaging tool sub-assembly. The sub-assembly includes a hub having a mounting portion, a ground engaging tool securable to the hub or integrally formed therewith, and a weight having a body with an open aperture having a mouth, the mouth configured for enabling the weight plate to be threaded over the elongate structure so that the elongate structure extends through the aperture, and the open aperture configured so that the weight plate is maneuverable over a portion of a length of the hub whilst in situ on the elongate structure and to be beatable on the mounting portion. The ground engaging tool is connectable to a respective one of the hubs of the tilling assembly whilst that hub is retained interconnected in situ on the tilling assembly, and without removing another ground engaging tool from the tilling assembly.

In one aspect, a system for monitoring frame levelness of an agricultural implement may include first and second sensors configured to detect first and second parameters indicative of forces exerted on first and second ground engaging tools of the implement by the ground, respectively. The system may also include a controller configured to monitor a parameter differential between the first and second parameters based on measurement signals received from the first and second sensors, with the monitored parameter differential being indicative of at least one of pitch or roll of a frame of the implement. The controller may be further configured initiate a control action associated with adjusting the pitch and/or the roll of the frame based on a magnitude of the monitored parameter differential to adjust an orientation of the frame relative to the ground.

In one aspect, a system for monitoring the condition of discs of agricultural implements includes a plurality of discs configured to be supported relative to an agricultural implement, and a field profile sensor configured to generate data indicative of a field profile of an aft portion of the field located rearward of the plurality of discs relative to a direction of travel of the agricultural implement. In addition, the system includes a controller communicatively coupled to the field profile sensor. The controller is configured to monitor the data received from the field profile sensor and determine an operating condition of one or more of the plurality of discs based at least in part on the field profile of the aft portion of the field.
