A friend picked up an old Henry pan scrapper (of about one and a half yards capacity) a couple of years ago and pulls it behind my John Deere 'R'. He had moved quite a bit of dirt with a skid steer previous to getting the Henry and he said the Henry was miles ahead of the skidsteer in both speed and comfort for moving dirt. The old 'R' is only rated at 48 hp but it will develop over 6600 lbs of pull on the drawbar. It's ballasted right up and with operator weighs in over 10,000 lbs. It handles the Henry quite well. :D
