Abstract: An agricultural implement configured to be propelled by a prime mover. The implement comprises a toolbar configured to support a plurality of agricultural tools. The toolbar is a front-folding toolbar configured to be shifted forward from an operational position to a transport position. The implement further comprises a draw-bar extending forward from the toolbar and configured to be coupled with the prime mover. The draw-bar is rotatably connected with the toolbar via a connection assembly that presents a generally laterally extending rotational axis, such that the draw-bar is configured to rotate vertically about the rotational axis.

Abstract: A tillage coulter unit (22, 122) adapted for use with a farm implement (10) permits high speed tillage operations (e.g., field fertilization using liquid fertilizer such as ammonia, or seeding) without undue soil disruption or fertilizer vaporization. The coulter unit (22, 122) includes an upright, rotatable coulter blade (26, 130) with a gauge assembly (28, 132) operable to limit the depth of the coulter blade into soil and to minimize soil disruption. The gauge assembly (28, 132) preferably includes a pair of elongated, shiftable belt or chain loops (74, 212, 214) positioned in straddling relationship and astride the blade (26, 130). The loops (74, 212, 214) present lower runs (96, 212a, 214a) which substantially contact the soil as the unit (22, 122) traverses a field.
