Patent Images
1. A closing assembly of a row unit for an agricultural implement, comprising:
- a frame configured to support ground-working tools of the row unit;
a plurality of arms coupled to the frame, wherein each arm of the plurality of arms is independently rotatable about a common axis, and each arm is configured to be coupled to a closing disc configured to direct soil into a trench;
a bolt configured to couple the plurality of arms to the frame, wherein the bolt extends along the common axis, the bolt extends through an opening in an end of each respective arm of the plurality of arms, and each arm of the plurality of arms is rotatable about the bolt; and
a plurality of coil springs, wherein each coil spring of the plurality of coil springs is configured to urge a respective closing disc toward a soil surface, and each coil spring extends about the bolt and the end of a respective arm of the plurality of arms.
