Towed farm machine

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 mounted for movement with one of said wheel support arms;
• a second ground-engaging member being mounted for movement with another of said wheel support arms;
• and said ground engaging members being so located relative to said ground wheels that selective operation of said adjustment mechanisms will first cause said ground wheels to be moved against the ground to cause the main frame to be moved through said working range and then will cause said ground-engaging members to be moved against the ground to move the frame through said transport lift range.

In a combination of a towed implement and a trailer for the endwise transport of said towed implement, with the implement including a main frame which is elongated in a direction transverse to a normal working direction, and is supported on a pair of ground wheels carried by wheel arms that are mounted to the frame for pivoting vertically about a transverse axis, and with the trailer including a platform located at a pre-selected transport height and supported on a pair of transport wheels, the improvement comprising;

• said towed implement having a pair of lift arms vertically pivotally mounted to said main frame at locations spaced from each other transverse to said normal working direction;
• a pair of auxiliary wheels respectively mounted to said pair of lift arms;
• an adjusting mechanism connected between said main frame and said pair of lift arms for pivoting them such that said main frame is lifted so as to elevate said ground wheels above said transport height;
• and said trailer having a length sufficient for supporting said towed implement when lowered thereon after the implement and trailer are moved relative to each other so as to position the trailer beneath the implement in a direction of travel transverse to said normal working direction.
