The 566 is an excellent baler. I've got 3,000 rolls on mine and its not broken in good. If the baler is well maintained there should be nothing wrong with 9,000 bales of usage. The 566 puts up a 5x6 roll that can werigh close to 2000#. The baler has a hydraulic density setting and will put up almost twice the hay in a same size roll of a different baler. You can dial any size roll you want but sometimes its hard to convience people that your 5 ft roll has twice the hay of your neighbors.
