Abstract
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.
Claims17
A furrow following device for a planting machine, the furrow following device comprising:
- an attachment bracket having a portion provided for attachment to a row unit of a planting machine;
- an arm provided with a ground-facing surface for engagement with the soil during planting;
- and
- a mount having a first portion coupled to the attachment bracket, the mount further having a second portion at least partially defining a pivot connection with the arm, the pivot connection providing relative rotation between the arm and the mount;
- wherein 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,
- wherein the mount includes a first link having a first end pivotally coupled to the attachment bracket and a second end pivotally coupled to the arm, and the mount further includes a second link having a first end pivotally coupled to the bracket and having a second end pivotally coupled to the arm, and
- wherein the first and second links are normally biased to have a parallel relationship, and wherein one of the first and second links includes a selective sliding joint operable to enable the linkage to be selectively tripped to transition from the parallel relationship to a non-parallel relationship.
A furrow following device for a planting machine, the furrow following device comprising:
- an attachment bracket having a portion provided for attachment to a row unit of a planting machine;
- an arm provided with a ground-facing surface for engagement with the soil during planting;
- and
- a mount having a first portion coupled to the attachment bracket, the mount further having a second portion at least partially defining a pivot connection with the arm, the pivot connection providing relative rotation between the arm and the mount;
- wherein 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,
- wherein the spring is held in tension throughout an entire range of motion of the arm, the range of motion of the arm being limited by an abutment surface of the mount, and
- wherein the abutment surface and the pivot connection are provided by parallel, spaced pins extending between lateral side plates of the mount that flank the arm.
A furrow following device for a planting machine, the furrow following device comprising:
- an arm provided with a ground-facing surface for engagement with the soil during planting;
- and
- a pivot connection located along the arm, the pivot connection defining an axis for rotation of the arm;
- wherein the arm is supported by a compliant mount including a spring, and
- wherein the pivot connection is positioned at a fixed location along the arm that is between the ground-facing surface and a portion of the arm to which the spring is attached.
