Abstract:
In a towed farm implement including an elongate main frame extending transverse to a normal working direction, a pair of wheel support arms respectively coupled to transversely spaced locations on said main frame for pivoting vertically about a transverse axis, a ground wheel mounted to each wheel support arm, an adjustment mechanism coupled between said main frame and each wheel support arm for selectively moving said arm, and hence, said main frame through an operating range, and a draft tongue coupled to the main frame for connecting the implement to a towing vehicle, the improvement comprising: said towed implement further including a lift mechanism coupled to said main frame and including at least one vertically movable ground-engaging member for selectively raising said main frame through a transport lift range in addition to said operating range; said lift mechanism including each of said wheel support arms; said at least one ground-engaging member being coupled to said at least one wheel support arm for vertical movement therewith and being so located relative to the ground wheel associated with said at least one of said wheel support arms that operation of said adjustment mechanisms will first cause movement of said ground wheels against the ground so as to move said main frame through its operating range and then cause said at least one ground-engaging member to move against the ground to cause said main frame to move through said transport lift range.
