ABSTRACT:
A utility cart and a folding stacking frame for mounting agriculture implements is disclosed. The folding stacking frame includes wings that extend to a working position transverse to the direction of travel of the utility cart to extend across numerous rows of crops. The frame permits the wings to be folded forward so that they are generally parallel with the direction of travel, and then stacked above the utility cart in a transportation position. The wings can be provided with self-tucking wheels that provide support for the wings when in the working position, and which tuck to a collapsed position when the wings are folded to the transportation position. The utility cart can ride on tracks which closely follow the contours of the ground. The track construction utilizes idler wheels mounted on tandem arms to support the track. The idler wheels pivot independently from each other, and allow the track to twist and bend to match the contours of the ground.
