Abstract

An agricultural implement includes a frame, a grow medium manipulation surface configured to manipulate and move a growing medium and at least one elastomeric torsion element coupled to the surface. The growing medium manipulation surface moves between a first growing medium engagement position in which the surface manipulates and moves the growing medium and a second growing medium non-engagement position. The elastomeric torsion element resiliently biases the surface towards the first growing medium engagement position. In one exemplary embodiment, the growing medium engagement surface comprises the surface of a furrow opening device on an agricultural implement. In one exemplary embodiment, the implement additionally includes an adjustment mechanism coupled to the elastomeric torsion element. The adjustment mechanism moves between a first adjustment position in which the torsion element biases the surface towards the first engagement position with a first force and a second adjustment position in which the element biases the surface towards the first engagement position with a second force. In another exemplary embodiment, the adjustment mechanism also enables the elastomeric torsion element to apply a reverse force biasing the surface away from the first growing medium engagement position.
