摘要:
A furrow closing wheel assembly includes a closed loop that has an inner surface, an outer surface, a first lateral surface and a second lateral surface. Each of the first and second lateral surfaces has a channel therein. Flanges positioned on a hub are extendable into the channels to couple the hub to the loop. A plurality of teeth extends upwardly from the outer surface. Each of the teeth has a front face, a rear face, a first side, a second side and an apex positioned distal to the loop. Each the front faces is faceted such that the front faces are absent of a substantial planar surface lying in a plane that is orientated parallel to an axis of rotation of the loop. The front face of each of the teeth is a leading face of the teeth extending into soil when the loop is positioned on the hub.
