ABSTRACT:
An assembly for opening and closing a furrow in soil includes a furrow opener with a pair of discs positioned at an angle relative to each other. The discs each have an inner side facing toward each other and an outer side facing away from each other. Each disc also has a leading edge and a trailing edge relative to a travel direction. A furrow closer includes a pair of wheels, each having an inner side facing toward each other and positioned adjacent to a corresponding disc outer side. Each wheel also has a leading edge positioned between a corresponding disc leading edge and disc trailing edge, and a trailing edge positioned rearward of a corresponding disc trailing edge relative to the travel direction.
