Abstract
A tillage implement includes a main frame with adjustable toolbar sections thereon which each support respective tillage units thereon for engaging the ground. According to one aspect of the invention, the toolbar sections are angularly adjustable about a pivot head at one end thereof while also being slidable in a longitudinal direction of the toolbar section to maintain alignment of the tillage units. The pivot head is elongate in a direction transverse to the toolbar section to resist moments applied to the toolbar section by the tillage units engaging the ground while the toolbar section remains adjustable. In another aspect of the invention, the tillage units each comprise a trailing arm supporting the respective coulter disks thereon. The trailing arm is pivoted between two side plates fixed to the toolbar section and biased downward by a spring enclosed between the side plates to resist debris catching on the spring.
