Had a chance to demo 60" 757 and Super B on five acres today. Equivalent, high quality cut on lawn area at about 2.5 - 3". However, the rest of the property was cut at 4" by both machines. The Super B did not scalp as much, had better trim depth and visibility near fences and obstacles, had more intuitive drive controls, weighed less, had better transmission(s), and outstanding blade access. However, with a 4" cut in about 12" mixed pasture grass, the 7-Iron II deck did a much better job than the apparent Triton Knock-off used by Walker. The 7-Iron gave a perfectly even cut in all grass thicknesses and at all speeds. The Walker would leave strips of grass anytime it got loaded. Also, the grass dispersion from the discharge was not even close. The 7-Iron threw the clippings about 10 feet--the Walker had difficulty reaching 4-5 feet. JD and Walker are the only two strong dealers in my area. Any recommendations from your experiences?
