I am a homeowner in the market for a zero turn mower to save time. My yard is about 4 acres and fairly smooth.(I brought a demo home and had no problem going 8 mph) We have a 7 acre pond which is home to several snakes, so my wife insist on cutting to 1" or less. Most zero turn mowers list their lowest cutting height at 1.5 inches. My question is: Can the decks be adjusted down another 1/2 inch? Thanks in advance.
