Patent

CA 1071917

ABSTRACT OF THE DISCLOSURE Four or more cultivator arms or shanks are pivoted to the front and rear of a main frame and are interconnected by linkage so that if a cultivator blade on one arm strikes an obstruction, then it moves rearwardly to clear same and at the same time the others that are interconnected, move forwardly by a lesser amount thus absorbing the movement of the cultiva- tor blade striking the obstruction. When the obstruction is passed, the engagement of the remaining blades with the ground, returns them to the original position thus returning the tripp- ed blade to the original position.
