We have a small farm on which we raise cattle. Currently I have a 504C round baler which I pull with a 31HP Kabota. The baler works good but it is hard to start a bale and it seems I'm always on the edge of something going wrong. So I'm looking to upgrade, so far I have looked at a 1993 New Holland 640 which appears to be in great shape but I'm not sure if the Kabota could power it? Also found a Hesston 550 which also looks to be in great shape but I know little or nothing about them other than it makes a smaller bale and looks as though my tractor could pull it. Currently I bale about 100 bales per year, eventually I hope to bale upwards of 400 round bales per year. Any insights or suggestions?
