CLOSING SYSTEM FOR AN AGRICULTURAL IMPLEMENT
First Claim
Patent Images
1. A row unit for an agricultural implement comprising:
- a support structure;
a closing disc configured to move soil into a trench, the closing disc rotatably coupled to a first portion of the support structure via a first arm to facilitate vertical movement of the closing disc relative to the support structure, 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 to block vertical movement of the first arm; and
a packer wheel positioned aft of the closing disc and configured to pack soil over the trench, the packer wheel rotatably coupled to a second portion of the support structure via a second arm, wherein the closing disc and the packer wheel are independently movable relative to one another.

Abstract
A row unit for an agricultural implement includes a closing disc configured to move soil into a trench. The closing disc is rotatably coupled to a first portion of a support structure via a first arm to facilitate vertical movement of the closing disc relative to the support structure. The row unit also includes a packer wheel positioned aft of the closing disc and configured to pack soil over the trench. The packer wheel is rotatably coupled to a second portion of the support structure via a second arm. The closing disc and the packer wheel are independently movable relative to one another.

10. 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 and rotatably supported by a first arm that is pivotally coupled to the support structure by a first pivot, wherein 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; and a packer wheel suspended from the support structure at least in part by a second biasing member and rotatably supported by a second arm that is pivotally coupled to the support structure by a second pivot, wherein 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, and 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, and the first pivot is coupled to the support structure at a position that is vertically below the second pivot. - View Dependent Claims (22)

15. 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 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 to a central region of the support structure that is vertically above the lower region, and the closing disc and the packer wheel are independently movable relative to one another in a vertical direction relative to the support structure. - View Dependent Claims (16, 17, 18, 19, 20)
