1. In an implement, a frame having an elongated beam and a forwardly extended hitch bar, means having a wheel and an upright shaft connected to the wheel located adjacent one end of the beam for supporting the one end of the beam, means rotatably mounting said shaft for movement about a generally upright axis, a lateral arm secured to the shaft for rotating the shaft, lift means connecting the means rotatably mounting said shaft to said one end of the beam for changing the elevation of said beam, said lift means comprising a first upright member attached to the beam, a second upright member attached to the means rotatably mounting the shaft, a pair of generally parallel first links pivotally connected to the first upright member and the second upright member, generally upright arm means secured to one of the first links, fluid motor means including a cylinder and a piston rod operable to change the elevation of said beam, first pivot means mounting the fluid motor means on the First upright member, second pivot means connecting the fluid motor means to the arm means whereby movement of the piston rod relative to the cylinder changes the elevation of the beam, hitch means secured to the frame, said hitch means comprising a first member rotatably mounted on the hitch bar for rotation about a horizontal axis generally parallel to the hitch bar, a second member mounted on the first member, said second member being rotatable about a generally upright axis, a laterally directed bar connected to the second member, rod means connected to the laterally directed arm and laterally directed bar whereby the shaft is rotated to steer the wheel on relative movement between the hitch means and the frame about said generally upright axis, a transverse member connectable to draft links of a tractor, link means connecting the second member with the transverse member, and means to adjust the length of the link means.

9. In an implement, a frame having an elongated beam, means having a wheel and an upright first shaft connected to the wheel located adjacent one end of the beam for supporting the one end of the beam, means rotatably mounting said first shaft for movement about a generally upright axis, a lateral arm secured to the first shaft, lift means connected to the means rotatably mounting said first shaft to said one end of the beam for changing the elevation of said beam, hitch means secured to the frame, said hitch means comprising a first member rotatably mounted on the frame for rotation about a generally horizontal axis extended generally in the direction of the movement of said implement, a second member mounted on the first member, said second member being rotatable about a generally upright axis, said second member comprises an upright sleeve secured to the first member and a second shaft rotatably mounted in said sleeve, a laterally directed first bar connected to the top of said second shaft, rod means connected to the lateral arm and laterally directed first bar, a second bar secured to the bottom of the second shaft, a transverse member connectable to the draft links of a tractor, and link means connecting the second member with the transverse member, said link means comprising upper and lower links connecting the bars to the transverse member.
