Patent ID: 6978727

Claim:
A ground engaging seed delivery device comprising an elongate support arm pivotally mounted to a driving means via a mounting means adapted to accommodate vertical linear displacement, wherein said support arm has an offset coulter disc fitted at a first end thereof followed by a back swept seed delivery tube and a packer wheel at the remote end thereof adapted to follow a soil contour such that said support arm will also follow said soil contour, wherein a soil control arm comprising an elongate arm and a ground engaging foot is positioned on said support arm to act between said coulter disc and packer wheel with at least part of said foot engaging the soil between said coulter disc and said packer wheel adjacent said seed delivery tube so that said soil control arm will follow a furrow formed by said coulter disc and prevent said furrow divot from either collapsing or being thrown into the furrow prior to delivery of seed into said furrow between said coulter disc and said packer wheel, such that said packer wheel can replace said divot immediately following delivery of seed to said furrow whilst allowing said soil control arm to maintain a constant presentation to said soil notwithstanding changes in soil contour, said control arm including a foot adapted to engage the ground adjacent said furrow from about the position of formation by said coulter disc to at least the position of said seed delivery tube.
