Abstract: A conduit for an agricultural system includes a first end configured to couple to a metering system, a second end configured to couple to a pipe, one or more bellows disposed adjacent to the second end and configured to enable the conduit to flex adjacent to the second end, and a substantially rigid portion extending generally longitudinally from the first end to the one or more bellows, where the substantially rigid portion substantially rigidly supports the conduit between the first end and the one or more bellows.

Abstract: A tank support assembly for an agricultural implement includes a primary connecting member and first, second, and third support members. The primary connecting member is configured to couple to a main frame assembly of the agricultural implement, where the primary connecting member extends substantially along a longitudinal axis of the agricultural implement. The first support member is configured to couple to the primary connecting member at an end of the first support member. The second and third support members are configured to couple to the first support member, the primary connecting member, or a combination thereof, at ends of the second and third support members. The first support member extends substantially vertically upward from the primary connecting member and the second and third support members extend generally upward and generally outward from the primary connecting member.

Abstract: A coulter assembly for an agricultural implement. The coulter assembly includes a support structure and a disc blade rotatably mounted to the support structure. The coulter assembly also includes a spring assembly coupled to the support structure and configured to urge the disc blade into soil. The spring assembly includes a variable rate spring.

Abstract: A fastening arrangement attaches a row unit to the tool bar of an agricultural implement. The fastening arrangement includes an elongated flat operatively connected to the tool bar. The elongated flat has a leading surface lying in a first plane nonadjacent to a second plane which includes a trailing surface of the tool bar. A head bracket is adapted to receive a row unit. The head bracket has an aperture therethough and is supportable on the elongated flat. A clamping nut and bolt combination is configured to fasten the head bracket to the elongated flat. The clamping nut and bolt combination includes a bolt adapted to pass through the aperture of the head bracket and engage the clamping nut in a mating relationship.

Abstract: The selective positioning of row units along a planter tool bar is facilitated by introducing an elongated channel of generally C-shaped cross-sectional configuration intermediate the tool bar and a plurality of row unit head brackets. The channel is welded or otherwise fixed to the tool bar with the open edge of the “C” facing away from the tool bar and the head brackets are fixed to the channel by clamping nut and bolt assemblies. The bolts extend through the clamping brackets and engage corresponding clamping nuts. The clamping nuts are positioned within the “C” and may be slid along the inner edge of the channel to any preferred position. The bolts are then and tightened fixing the head bracket at the selected at location.

Abstract: A precision hoe opener assembly is provided with improved accuracy of seeding as well as improved control over the opener and packer wheel assemblies. The opener assembly includes a hydraulically-driven parallel linkage assembly, a lost motion linkage, a hoe opener, and a packer wheel. The design provides improved seeding accuracy, by adjusting assembly components to and compensating for changes in terrain elevation.
