I've got one acre of flat smooth lawn and two acres of flat but rough and rocky (big flat rocks that stick out of the ground 2-3 inches) to mow with my new Tiger Cub 61" Briggs (bought the discontinued deal Scag has on). I've never used a ztr and after mowing the yard twice, I've a few questions. How do I turn without tearing up the lawn? How do I turn sharply around trees without tearing up the ground around the tree? How do I avoid scalping? What height should I mow each lawn at? (fescu one acre, combination two acre) What pressure will give the smoothest ride/performance in the 24-12-12 rears and 13-650-6 fronts? How often will the blades require sharpening mowing once per week? Mulch blades or side discharge? Anything else I should ask but don't know enough to ask? thanks!
