Abstract
A parallelogram boom device for mounting agricultural implements has a parallelogram arrangement of a first upper beam horizontally and longitudinally aligned with a second upper beam plus a single lower beam longitudinally aligned with the first and second upper beams, but at a lower horizontal level. A first hydraulic piston unit acts via a bridle to raise and lower the parallelogram arrangement relative to the ground. An agricultural implement is attached at one end to a mounting arm supported via the parallelogram arrangement and a second hydraulic piston unit serves to move the implement in an arc about its attached end. The new boom devices also have the capability of retracting the supported implements rearwards from their forward direction of travel in the event the implement encounters a rock, stump or like obstruction.
