I've got a need for a small round baler. I have an excellent market for the small rolls. I've found ads for all these balers. All I know about the 503i is he's spent about $100 in new pickup teeth, about all the ad says. He's asking $4000, looks good in the couple of pics I saw of it. The Hesston 530 is suppose to be an excellent shape, and seen very little hay. Owner says it's never spent a night outside and that the only reason he's selling is that he bought a bigger baler. On the pics it looks to be hydraulic tie, but not for sure. Asking $5800. And last the NH 634 is a 1996 one owner, they say it's average about 150 rolls a year since new, electric tie, looks dirty in the pics but than that, looks good. Asking $6000. I've got good dealer support for all three within an hour or so. What's the best baler for 3 or 4 hundred rolls??
