Title: Paired row furrow opener

Abstract: A ground-engaging paired row furrow forming tool includes a tool body having fore and aft ends with an outer edge defined on each of two opposing sides of the tool body. A furrowing wing is located adjacent each of the opposing sides and protrudes from bottom portions of the tool body. The tool body has lower surfaces including a central front surface portion which is angled upwards towards the fore end and a center passage is defined between the furrowing wings. This passageway is in part defined by a central rear surface portion which is adapted to be substantially aligned fore to aft in a direction of travel T during operation of the ground engaging tool. This paired row opener works well without compromise in a broad range of soil conditions without fouling and enables planting of seed rows spaced widely apart while minimizing soil surface disturbance.
