Transportable wide swath trailing implement

A transportable trailing wide-swath wheel-supported implement comprising

• a wide-swath frame for supporting at least one working element;
• a drawbar pivotally connected to the frame about a substantially vertical pivotal axis;
• at least two wheel legs each having an inner end pivotally mounted on the frame about a substantially vertical pivotal axis;
• and
• an implement-supporting wheel mounted for rotation about a substantially transverse horizontal axis on the outer end of each of said wheel legs;
• the wheel legs and drawbar each being pivotally movable to assume selectably a retracted position at a relatively small acute angle to the swath dimension of the frame and an extended position at a relatively large acute angle or right angle to the swath dimension of the frame, thereby permitting the effective transverse width of the implement to vary between a relatively small transport mode dimension in the retracted position of said drawbar and wheel legs and a relatively large working mode dimension in the extended position of said drawbar and wheel legs;
• wherein the pivotal connection to the frame of one of said wheel legs is located on the side of the frame opposite that on which the pivotal connection of another of said wheel legs is located, and the pivotal connection for the drawbar is located generally centrally along the frame between the locations of the pivotal connections of the wheel legs, and wherein the wheel legs in extended position extend generally rearwardly of the frame whilst the drawbar in extended position extends generally forwardly of the frame;
• and
• wherein one of the wheel legs swings generally inwardly through an angle less than a right angle to move from extended to retracted position whilst the other of the wheel legs swings from rearward to generally forward orientation through an angle of the order of 180.degree. or more to move from extended to retracted position.
