Abstract: A scraper assembly of an agricultural row unit includes an inner scraper configured to engage an inner surface of a disc. The scraper assembly also includes a biasing member engaged with the inner scraper and configured to urge the inner scraper toward the inner surface of the disc. In addition, the inner scraper has an engagement feature configured to contact an outer scraper to block translational movement of the inner scraper relative to a frame of the agricultural row unit.

Abstract: In one aspect, a system for controlling the operation of rotating ground-engaging components of an agricultural implement may include a rotating ground-engaging component configured to rotate relative to soil within a field as the agricultural implement is moved across the field. The system may also include a rotational speed sensor configured to capture data indicative of a rotational speed of the ground-engaging component. A controller of the system may be configured to monitor a first-order derivative of the rotational speed of the ground-engaging component based on data received from the rotational speed sensor. Moreover, the controller may be configured to determine when a frequency of the monitored first-order derivative falls outside of a predetermined frequency range. Additionally, the controller may be configured to initiate an adjustment of an operating parameter of the ground-engaging component to return the frequency of the first-order derivative to within the predetermined frequency range.

Abstract: A seed tube guard for a row unit has a body having a first portion and a second portion. The second portion carries an audible alert material that is configured to produce an audible sound when scraped across rotating metal. The audible alert material has a material composition distinct from a material composition of the body carrying the audible alert material.

Abstract: A system for controlling the operation of a seed-planting implement may include a furrow-closing assembly having a closing disc. A controller of the system may be configured to determine when a penetration depth of the closing disc falls outside a predetermined depth range based on data received from a depth sensor. The controller may also be configured to control the operation of an actuator to adjust a down pressure applied to the closing disc to return the monitored penetration depth to within the predetermined depth range. Furthermore, the controller may be configured to determine an operational adjustment to be made to an additional tool of the seed-planting implement based on the adjustment made to the down pressure applied to the closing disc. In addition, the controller may be configured to control the operation of the additional tool to execute the operational adjustment.
