    摘要： A shank assembly including a rearwardly opening bracket pivotally mounting a shank. A tension link extends upwardly from a central portion of the shank and through an apertured strap. A stop member at the upper end of the link limits the downward rocking of the shank. An adjustable arm assembly including a trunnion slidably received over the tension link is pivotally connected to the bracket and adjustably compresses a down-pressure spring which encircles the link between the trunnion and the shank. Individual down-pressure adjustments can be made without affecting the transport height of the assembly.

    摘要： A soil working machine, such as a cultivator, has a frame beam to which a working element is connected by a support. The support is resilient or resiliently mounted and can deflect when the working element meets an obstruction, or heavy ground resistance, but the working element maintains its orientation in the soil. A control rod coextends with the support and four pivot points enable the element to be displaced without loosing its orientation. The working element is pivotally connected to the support by a pivot pin and the control arm also can be pivoted to that element. In a variant, the control arm is eliminated and a V-shaped share is hinged to pivot up and down between stops.
