An improved track frame assembly wherein the idler wheels are arranged to prevent loss of track contact with the terrain. Seriatim primary idler wheels are aligned to longitudinal outer lateral track edges. Secondary idler wheels are mounted interiorly of the outer wheels and longitudinally staggered to prevent the track from lifting or “caterpillaring” in spaces intermediate the primary idler wheels. The numbers, diameters, widths and positions of the secondary idler wheels are selected to overlap the track contact points of the primary idler wheels. A resiliently biased and/or slippery presser member, roller or slide assembly can alternatively be mounted to prevent vertical track flexion.
