Abstract: A pull-type folding implement, such as a grain drill, has individual and independent radial flotation for each of its drill units such that each unit can rise and fall, while remaining level, independently of the other, as well as cock and cant independently of the other as may be necessary to accommodate uneven ground terrain, yet the units may be folded into compact, fore-and-aft extending transport positions in which ground wheels thereof are retracted off the ground and the units are carried by a main, fore-and-aft carrier frame of the implement. A third, center unit may be provided between the two outer units and utilizes its own set of ground wheels during both field working and over-the-road travel when the other units are folded in, the center unit likewise having a floating connection with the carrier frame which permits the center unit to rise and fall, cock and cant when experiencing terrain irregularities.
