I would just add, think about the maintenance that goes with a ZTR. Might consider a deck that raises so deck service, blade sharpening are easier or you'll need a jack or you'll either have it picked up or be able to haul it yourself. My yard is 1.5 acre, cut it for years with a 38" rider. Moved up to a 48" BobCat CRZ, never look back, cut my mowing time to nearly nothing but it is little more time to maintain the machine properly. How do you plan to sharpen and balance blades, little more picky than the old rider. Anywho, good luck on your choice. For what it's worth, you can't run fast enough to put me in front of a B&S engine, Cheers, Ray
