Vehicle for agricultural use with transport wheels

In a wheeled vehicle to be moved over the surface of the ground in first and second mutually perpendicular directions, in combination:

• a horizontal, generally rectangular frame having first and second sides extending in said first direction and first and second ends extending in said second direction;
• a rigid draft member comprising first and second portions intersecting to jointly define an obtuse angle in a common plane, said first and second portions each including an end joined to the corresponding end of the other portion and a free end, said draft member being capable of applying force in tension and in compression along a line of action extending between the free ends of said portions;
• coupling means connecting said free end of said first portion to said frame, at a site along said first side between the center thereof and a first, forward end of said frame, for pivotal movement of said draft member about a first, generally vertical axis between a first position and a second position;
• a first auxiliary member for removably connecting a first site on said draft member remote from said coupling means to said first end of said frame at a site remote from said first side;
• and
• a second auxiliary member for removably connecting a second site on said draft member less remote from said coupling means to said first side of said frame at a site thereon between the center thereof and said second end;
• at least one agricultural implement having earth-working wheels, rotatable about a common axis, and caster wheels laterally spaced from said common axis;
• means mounting said frame on said implement for rotation about a pivotal axis extending in said first direction and located between said caster wheels and said common axis with said second side of said frame extending laterally beyond said earth-working wheels;
• a plurality of transport wheels spaced along said second side for tracking in said first direction;
• and
• reversible means for causing pivotal movement of said frame with respect to said implement, raising or lowering said second side of said frame, and simultaneously lowering or raising said first side of said frame respectively, to transfer a portion of the weight of said implement between said earth-working wheels and said transport wheels.
