An agricultural system includes a tow bar, a first row-cleaning device, and a second row-cleaning device. The first row-cleaning device is attached to the tow bar via a first frame and includes a first roller device in a trailing position relative to a first furrow-opener disk and configured to crush standing residual plant matter along a first path on a field. The second row-cleaning device is attached to the tow bar via a second frame and includes a second roller device in a trailing position relative to a second furrow-opener disk and configured to crush standing residual plant matter along a second path on the field. The second roller device is offset longitudinally from the first roller device.

A roller assembly for smoothing an expanse of granular media such as golf bunker sand, snow, horse race track dirt, or other media. The assembly has one or more rollers having a longitudinal axis. Each roller includes wires spaced from the axis to define a roller surface. Each wire is resiliently flexible to distort inwardly in response to force of contact on, and to recover during release of force from, the granular media as the roller rotates about the axis on the granular media. A shaft extends along the axis of the roller assembly between the arms of a yoke with a handle extending therefrom. As the roller surface traverses the media, at least some of the media is flung outwardly of the roller, smoothing the expanse. The roller assembly may be manually operated or may be towed behind a towing apparatus.

An agricultural system for monitoring plugging of a ground-engaging tool of an agricultural implement includes a signal transmission device configured to transmit wireless signals and a target provided in operative association with the ground-engaging tool, with the target being configured to receive the wireless signals transmitted from the signal transmission device. Additionally, the agricultural system includes a computing system configured to receive moisture data indicative of a moisture content within the field, adjust an output frequency for the signal transmission device to transmit the wireless signals from a current output frequency to an adjusted output frequency based at least in part on the moisture data, and determine when the ground-engaging tool is experiencing a plugged condition based at least in part on an attenuation parameter of the wireless signals transmitted by the signal transmission device at the adjusted output frequency and received by the target.
