I have a chance to pick up a used one (280 hours). Gas, 27HP Kohler. The 72" cut is probably more than I need, but @ 7K give or take it's tempting. Thoughts on this machine verses a new JD 520A w/ 60" deck? I am mowing residentially in and around an apple orchard. Feels like 72" may be difficult in the orchard terrain. Thanks.
