摘要:
A furrow following device includes an attachment bracket having a portion provided for attachment to a row unit of a planting machine. An arm is provided with a ground-facing surface for engagement with the soil during planting. A mount of the furrow following device has a first portion coupled to the attachment bracket, and a second portion at least partially defining a pivot connection with the arm. The pivot connection provides relative rotation between the arm and the mount. The mount is a compliant mount provided with a spring that exhibits an elastic bias force as the arm is raised toward the attachment bracket.
