First Claim
1. A ground engaging paired row furrow forming tool comprising:
- a tool body having fore and aft ends, said body having surface portions defining an outer perimeter extending on each of two opposing sides of the tool body;
a furrow forming wing adjacent each of the opposing sides and protruding in spaced apart relation from bottom portions of the tool body, each wing having an outer surface extending downwards and inwards from the outer perimeter; and
, a forward surface extending from the central front surface downwards and outwards to intersect with the outer surface at a furrow forming edge; and
said tool body having lower surfaces including a central front surface portion which is angled upwards towards the fore end and which leads into a central passage extending rearwardly of the tool body between the wings, which passage is capable of being substantially aligned fore to aft in a direction of travel during operation of the furrow forming tool.

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.
