A work vehicle includes row units. The row units each include an air pressure device configured to generate a pressure differential for retaining a commodity against a metering element to singulate and meter a commodity. The air pressure device includes an exhaust structure with a passage configured to direct an exhaust substance to the ground as the row unit travels.

In one aspect, a system for detecting plugging of an agricultural implement may a disc rotatably coupled to a frame member, with the disc configured to rotate relative to soil within a field as the implement is moved across the field. The system may also include a disc scraper coupled to the frame member, with the disc scraper configured to remove the soil from the disc as the disc rotates relative to the soil. Furthermore, the system may include a sensor configured to detect a parameter indicative of an acceleration of the disc scraper relative to frame member. Additionally, a controller of the system may be configured to monitor the acceleration of the disc scraper relative to the frame member based on data received from the sensor. Moreover, the controller may be further configured to determine when the disc is plugged based on the monitored acceleration.

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.

A plugging control system for an agricultural implement includes a sensor configured to output a sensor signal indicative of plugging of a ground engaging component and a controller having a processor and a memory. The processor is configured to receive the sensor signal indicative of plugging of the ground engaging component from the sensor, determine whether the plugging exceeds a threshold value, and in response to the plugging exceeding the threshold value, output a monitoring signal to perform a monitoring operation, output a control signal to perform a control operation, or both.

A scraper assembly for a split gauge wheel of a planter row unit. The scraper assembly includes a scraper blade having a finger projection configured to extend downwardly into a gap between the inner and outer wheel members of the split gauge wheel. An inner scraper flange extends laterally inward from the finger projection and is disposed in proximity to a circumferential periphery of the inner wheel member. An outer scraper flange extends laterally outward from the finger projection and is disposed in proximity to a circumferential periphery of the outer wheel member. As the gauge wheel rotates, the inner and outer scraper flanges remove soil buildup on the circumferential periphery of the respective inner and outer wheel members and the finger projection removes soil buildup in the gap between the inner and outer wheel members.

A work vehicle with a metering system, airflow system, and a covering structure moveable between various positions for user access includes features that facilitate assembly and/or disassembly of the metering system. The work vehicle has a venturi structure with a plurality of venturi tubes that are disposed in a compact arrangement.
