I feel for you with the problems. I didn't spend much on what I made, only needed to get square tubing (already had 1" shaft, wheels and hubs). I just measured the frame, this one's 75" long (not counting tongue) and 24" wide. I was more interested in the width for wheel track than length. I conjured up this idea nearly 20 years ago with the need to get around in a thick woods, then haul nearly a half mile to the nearest road. The uprights might be handier if they were removable, I welded these on. In this picture I hauled the 2 wheel tractor a mile incl. along the railroad to a neighbor's. I made the cultivator on the 2 wh. tractor, I like it cause I can tip it back (wheels off the ground) and turn around on the spot. The box on the atv was a factory reject toolbox drawer I got at the local scrapyard.
