1. A closing wheel assembly for a row planter, comprising:
- a frame having opposite first and second lateral sides;
a pair of closing wheels rotatably mounted on the frame;
a coupler for mounting the frame and closing wheels to the row planter, the coupler having opposite first and second lateral sides; and
a threaded bushing extending through the first sides of the frame and coupler;
an unthreaded bushing extending through the second sides of the frame and coupler; and
the threaded bushing being rotatable to adjust both sides of the frame relative to the coupler so as to simultaneously move the closing wheels for lateral positioning.

Abstract
A closing wheel assembly is provided for a seed row planter unit behind the gauge wheel assembly and furrow disks of the planter unit. The closing wheel assembly includes a coupler with a pair of closing wheels mounted thereon. A single pin removably extends through the coupler and through the gauge wheel assembly to detachably mount the closing wheel assembly to the gauge wheel assembly. Different closing wheel assemblies can be quickly mounted on the row unit, depending upon the type of seed being planted. The closing wheels are laterally adjustable via a rotatable threaded bushing so as to be centered behind the furrow disks.

7. A seed row planter, comprising:
-
a mounting bracket adapted to mount the row planter to a tool bar; a first frame; a pair of furrow disks on the first frame; a pair of gauge wheels on the first frame; a second frame detachably mounted to the first frame; a first pair of closing wheels on the second frame for use with planting a first type of seed; a third frame detachably mounted to the first frame as a substitute for the second frame; a second pair of closing wheels on the third frame for use in planting a second type of seed; and the second and third frames being interchangeably mounted on the first frame using a first coupling including a single non-threaded pin removably extending through one of the second or third frames and a non-threaded retainer on the pin to prevent withdrawal of the pin and using a second coupling including laterally extending posts on the first frame and forwardly open notches on the second and third frames received on the posts. - View Dependent Claims (8, 9)

10. A method of assembling furrow closing wheels onto a seed row planter unit comprising:
-
selecting a pair of closing wheels from a first set of closing wheels and a second set of closing wheels based on the type of seed to be planted; mounting the selected pair of closing wheels onto the row planter using a single thread-free pin removably extending through a frame on the selected set and a retainer to preclude withdrawal of the pin from the frame during use of the row planter unit the selected set of closing wheels is further mounted to the row planter unit by positioning forwardly open notches on the selected set onto posts on the row planter unit. - View Dependent Claims (11, 12, 13)
