Abstract:
1. An apparatus attaching a ground-engaging tool to an implement frame of an implement adapted to move along the ground in an operating travel direction, the apparatus comprising: a bore bracket defining a pair of laterally spaced parallel cylindrical bores; a pair of cylindrical shafts, one shaft slidingly engaged in each bore such that the shafts are maintained in a parallel orientation, wherein the shafts are connected such that the shafts slide in the bores substantially in unison; wherein the bore bracket is adapted for rigid attachment to the implement frame such that the bores and shafts are oriented substantially upright, and the pair of shafts is attached to the ground-engaging tool; and an actuator oriented substantially parallel to the shafts and attached to the bore bracket at a location substantially mid-way between the shafts, and attached to both of the shafts wherein the actuator is operative, when activated, to selectively exert a force between the bore bracket and the shafts to move the shafts up and down with respect to the bore bracket, and the actuator is operative, when inactive, to fix the shafts at a desired position with respect to the bores such that the shafts are prevented from sliding up and down in the bores when the attached ground-engaging tool is engaged in the ground.
