I liked the 4720, it is a strong work horse! I don't know the exact hours on it, as I kept having hour meter issues, after cutting 19 acres, it only put 1.5 hours on it, and it takes a lot longer then 1.5 hours to cut 19 acres with a 6' cutter, when they finally got the new dash to fix it, it said 79 hours, but looking at the rate of hours it would add and the amount of work I've put it through I would guess it was more in the 179 range, so, the new meter shows 10 hours, and I know I've done a whole lot more then 10 hours on it, I was pulling a hay trailer for8 hours each weekend day last week, plus my 2000' driveway I put in. There is a issue with it, but I haven't heard of anyone else having these issues. I hope the 6530 isn't that way. I have the forks for the 4720 and it didn't seem to pick up much at all weight wise, but sure did dig good. I was hoping to keep it for getting into the woods, but a 4720 and a 6530 costs a little to much for a trail cutter. Love that tractor though
