1. A seed furrow closing wheel comprising:
- a generally dish-shaped body having a central portion and a circumferentially extending, peripheral flange portion that projects obliquely outwardly away from said central portion,said flange portion being circumferentially notched to present a series of circumferentially spaced, obliquely projecting teeth, said teeth curving rearwardly with respect to the normal direction of rotation of the wheel,said body having a generally concave front side and a generally convex back side,the back sides of said teeth presenting a series of wedge surfaces for use in displacing and fragmenting a sidewall of the furrow as the wheel rotates down into the ground during use.

Abstract
A seed furrow closing wheel has a generally dish-shaped body defined by a central portion and a notched outer flange portion that circumscribes the central portion and projects obliquely outwardly from the plane thereof. The notched flange portion is configured to present a series of circumferentially spaced, non-radial, obliquely projecting teeth that function to fragment and squeeze together opposite sidewalls of the seed furrow when a pair of the wheels are rolled along opposite sides of the furrow outboard of the furrow itself, crumbling the sidewalls and covering the seeds.
