An agricultural assembly that includes an autonomous or semi-autonomous agricultural vehicle, an agricultural implement connected to the agricultural vehicle, and a plug detection system. The plug detection system includes at least one sensor connected to the agricultural implement for sensing an operational variable and a controller operably connected to the at least one sensor. The controller is configured for detecting a plugged state of the agricultural implement, in which matter hinders operation of the agricultural implement, dependent upon the operational variable of the agricultural implement.

A system for detecting the operational status of ground engaging tools for agricultural implements includes an agricultural implement including a frame and a ground engaging tool coupled to the frame. The system further includes one or more sensors supported relative to the frame. The sensor(s) are configured to capture data indicative of a fluid flow past the ground engaging tool as the agricultural implement is moved across the field. The system further includes a controller configured to monitor the data received from the sensor(s) and identify an operational status of the ground engaging tool based at least in part on a comparison between one or more monitored values associated with the fluid flow past the ground engaging tool as the agricultural implement is moved across the field and a predetermined threshold value.

An agricultural implement includes a frame having an elongate toolbar carrying a plurality of row units. A sensor is configured to detect residue accumulation between adjacent row units. An actuator is configured to raise or lower a row unit based at least in part on the residue accumulation detected by the sensor. Control systems and related methods are also disclosed.

The invention relates to a scraper device for a disc of an agricultural machine comprising:

a first outer scraper element comprising a suitable first scraper portion intended to rest against the outer surface of the first disc and a suitable first coupling portion intended to be coupled to a chassis of the agricultural machine;
a first inner scraper element comprising a suitable second scraper portion intended to rest against the inner surface of the first disc and a suitable second coupling portion intended to be coupled to the first coupling portion of the first outer scraper element;
the first inner scraper element being swivel-mounted with respect to the first outer scraper element around a second rotation axis;
characterized in that it comprises:
a resetting means connected to the second coupling portion to cause a rotational movement of the first inner scraper element along the second rotation axis, so as to press the second scraper portion against the inner surface of the first disc and so as to cause a rotational movement of the first outer scraper element along the first rotation axis to press the first scraper portion against the outer surface of the first disc.

An agricultural implement may include a frame and a row unit supported by the frame, where the row unit works a field as the implement is moved across the field. The row unit includes a first frame member coupled to a support structure of the row unit, a second frame member rotatable relative to the first frame member, and at least one cleaning wheel rotatable relative to the second frame member. Additionally, the row unit includes a depth stop member movably coupled to the first frame member, where the depth stop member is configured to set a lower height limit for the at least one cleaning wheel, with the second frame member being configured to abut against the depth stop member when the at least one cleaning wheel is disposed at the lower height limit.

A system for removing debris from a vision-based sensor of an agricultural machine includes an agricultural machine and a vision-based sensor supported on the agricultural machine. The vision-based sensor is configured to generate vision data. The system further includes a vibration source configured to be a separate component frons the vision-based sensor. The vibration source is supported on the agricultural machine. Moreover, the vibration source is configured to oscillate the vision-based sensor to remove debris from the vision-based sensor.

A shield assembly for a shaft includes a first tubular section having a first end and a second end and a second tubular section having a first end and a second end. The first and second tubular sections are each hollow receiving the shaft. The first tubular section includes a first outer diameter and the second tubular section includes a second outer diameter, the first outer diameter being greater than the second outer diameter. The first tubular section and the second tubular section are telescopically coupled to one another where the second tubular section is movably disposed at least partially within the first tubular section.
