Abstract
A parallel arm furrow opener assembly defines upper and lower front pivot axes and upper and lower rear pivot axes oriented horizontally and perpendicular to a travel direction. A furrow opener and a packer wheel are attached to a rear link of the assembly. In operation the furrow opener and the packer wheel are in fixed positions with respect to the rear link member, and a bias element is operative to exert a downward bias force on the furrow opener assembly. A front pivot line connecting the upper and lower front pivot axes is parallel to a rear pivot line connecting the upper and lower rear pivot axes, and the front and rear pivot lines are oriented at a pivot angle with respect to a vertical orientation, and the pivot angle is adjustable to vary a furrow depth of the furrow.
