Patent ID: 7334645

Claim:
A control arm for pulling a power take-off driven implement comprising: a frame having a first pivotal connection at a first end and a second spaced apart pivotal connection at a second end; a support wheel pivotally supporting the second end of the frame; a power train for operating the power take-off driven implement comprising an input shaft at the first end of the frame and an output shaft at the second end of the frame defining an in-line driveline axis therebetween; an intermediate power shaft spaced from the driveline axis and connecting the input and the output shafts; a front gearbox providing a constant, substantially perpendicular transfer of power from the input shaft to the intermediate power shaft, and a rear gearbox providing a constant, second perpendicular transfer of power directly from the intermediate power shaft to the output shaft; and wherein the support wheel for the frame is positioned forward in the direction of travel of the power take-off driven implement and rotatably attached to a wheel support beam pivotally secured to the frame and independently pivotable about a central pivot point relative to both the frame and the towed power take-off driven implement during forward travel of the control arm.
