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 ...


The invention claimed is: 1. A track assembly for use in a utility cart, the track assembly comprising: a frame including a tensioning structure adjustably spacing a first wheel a distance from a second wheel; a top tandem arm pivotally connected to said frame at a pivot member such that said top tandem arm will pivot freely relative to said frame in a substantially vertical plane, said first wheel being directly connected to a first end of said top tandem arm at one end of said frame; a bottom tandem arm having a front portion, a rear portion, a top po...
