Abstract: A row unit closing wheel assembly includes a closing wheel, a closing wheel arm, and a closing wheel shaft having a first end and a second end. The closing wheel is coupled to the first end and the closing wheel arm is coupled to the second end via a pivot joint. The row unit closing wheel assembly includes an adjustable mechanical assembly disposed at the pivot joint. The adjustable mechanical assembly is configured to adjust an angle of the closing wheel shaft relative to the closing wheel arm along a horizontal plane via movement of the closing wheel shaft about the pivot joint, the horizontal plane being orthogonal to a rotational axis of the pivot joint. The adjustable mechanical assembly includes interlocking teeth and is configured to utilize the interlocking teeth to adjust the angle.

Abstract: A wheel adapted for use with a trench closing assembly. The wheel has a circumferential tread coaxial with a central axis of the wheel, the circumferential tread extending axially an axial width. A continuous wall member joined with the circumferential tread extends radially inward to a central opening and axially outward from an inner edge of the circumferential tread by an axial distance, the axial distance not extending beyond a vertical plane that is perpendicular to the central axis at a midpoint of the axial width, whereby the circumferential tread and the wall member together defining a shape in the form of an uppercase Greek letter sigma.

Abstract: The disclosed devices, systems and methods relate to agricultural planters, particularly to a two-stage closing system for a planter row unit. In some implementations, the row unit includes a soil engaging member, where the soil engaging member engages at least one sidewall of a trench and displaces soil from the sidewall to cover the seed. In further implementations, the row unit includes a sensing system for sensing sidewall compaction and/or soil moisture.

Abstract: A system for a row unit of a planting implement includes a frame. A closing system is operably coupled with the frame. The closing system includes a closing arm operably coupled to the frame on a first portion of the closing arm, a closing disc operably coupled with a second portion of the closing arm, and an adjustment assembly operably coupled with the closing arm, the adjustment assembly configured to alter one or more operating parameters of the closing system. The system further includes a positioning system and a computing system communicatively coupled to the closing system and the positioning system. The computing system is configured to determine a location of the closing system based on data received from the positioning system, and alter the one or more operating parameters of the closing system from a first operating parameter to a second operating parameter based on the location of the closing system.
