Closing system for an agricultural implement

A row unit for an agricultural implement comprising:

• a support structure;
• a closing disc suspended from the support structure at least in part by a first biasing member that is coupled to the support structure at a first mounting point, wherein the closing disc is rotatably supported by a first arm that is pivotally coupled to the support structure by a first pivot, the closing disc is configured to be positioned aft of an opener disc and to move soil into a trench formed by the opener disc as the agricultural implement travels across a field in a direction of travel;
• and
• a packer wheel suspended from the support structure at least in part by a second biasing member that is coupled to the support structure at a second mounting point, wherein the packer wheel is rotatably supported by a second arm that is pivotally coupled to the support structure by a second pivot, the packer wheel is positioned aft of the closing disc, the packer wheel is configured to pack soil over the trench as the agricultural implement travels across the field, the closing disc and the packer wheel are separately suspended from the support structure to enable the closing disc and the packer wheel to move independently from one another in a vertical direction relative to the support structure, the first pivot is coupled to the support structure at a position that is vertically below the second pivot, and the first mounting point and the second mounting point are positioned rearward of the second pivot relative to the direction of travel.

A row unit for an agricultural implement comprising:

• a support structure configured to be coupled to a frame of the row unit;
• a closing assembly, comprising:
• a closing disc configured to move soil into a trench, wherein the closing disc is coupled to the support structure via a first arm pivotally coupled to a lower region of the support structure and via a first biasing member coupled to the support structure at a first mounting point, wherein the support structure comprises multiple apertures each configured to receive a pin, and the pin is configured to be inserted into one of the multiple apertures and to contact the first arm to block vertical movement of the first arm;
• and
• a packing assembly, comprising:
• a packer wheel configured to pack the soil over the trench, wherein the packer wheel is coupled to the support structure via a second arm pivotally coupled, via a pivot, to a central region of the support structure that is vertically above the lower region and via a second biasing member coupled to the support structure at a second mounting point, the closing disc and the packer wheel are independently movable relative to one another in a vertical direction relative to the support structure, and the first mounting point and the second mounting point are positioned rearward of the pivot relative to a direction of travel of the agricultural implement.
