    Abstract: The moveable plow shanks upon a skip row cultivator are mounted for vertical sliding motion. Each shank has a hydraulic cylinder connected to it by a flexible hydraulic line so that the tool bar to which the shanks are connected may be folded. By selectively energizing the hydraulic cylinders by a single valve, alternate cultivators are placed in the cultivating or non-cultivating position.

    Abstract: The plow device is adjustable so that it can be pulled and operated by a powered tractor utilizing reciprocating lowering and lifting rods actuated by a 3 hitch hydraulic piston and piston rod attached to 3 respective hooks one hook pivotally connected to vertical posts and two oppositely disposed hooks connected to the opposed front ends of the frame of said plow device. The plow device has a pivotally connected shank connected by a pivot pin therethrough which also extends through horizontal side frame beams. The shank carries a plow blade point at its lower end which cuts levees, furrows or cultivates the ground with suitable kind of cultivating attachment. A pivotally connected L-shaped crank arm is pivotally connected by pivot pin through hole in said crank arm and matching holes in said horizontal side beams of the frame and the upper end of said crank arm has several adjustment holes spaced apart from each other for use attaching a pivotal member by pivot pin through a hole thereof and extending through one of the adjustment holes in the upper end of said crank arm. A hydraulically operated piston is actuated by hydraulic fluid in a cylinder by pipe and valves communicating with each end of the cylinder so that said piston may be actuated forward for drawing said crank arm forward to lift a trailing wheel from the ground for safely transporting said plow device and wheel to clear levees around sections of lands in a field to be cultivated for growing crops such as rice crops.

    Abstract: The present invention envisions apparatus for rotating a pair of aligned shafts in equal arcs while allowing relative rotary motion of the shafts. In one embodiment, apparatus embodying the invention may comprise elongated linking means which has positioned on each end thereof a universal joint. An arm may be rigidly secured to each of the aligned rotary shafts and each of the arms thus secured may be operatively connected to one of the universal joints located at the end of the elongated linking means. A power assembly may be provided for moving the linking means in an arc about the parallel shafts thereby rotating the shafts. The power assembly is characterized by means for connecting a portion thereof with a central portion of the linking means in such a manner as to allow pivotal motion of the linking means relative to the power assembly. In addition, a portion of the power assembly is designed to allow limited universal motion of the elongated linking means about an axis normal to the longitudinal axis of the linking means.
