I live in North Texas. I have 4 acres of fairly flat land. I want to mow and mow quickly. I just sold two slow, slow garden tractors that would take me near 5 hours to mow my property. I'm looking at buying a Gravely 44Z (w/ 17hp Kawasaki). It has a mowing top speed of 9 mph. According to Gravely, it will mow my property in 1 hour. I know if I take into account a slower speed for a better cut, I should still finish in two hours. That's acceptable to me. Here's my question: My budget is between 4-5K. Am I buying a good mower (for $4100) that will do my job? I was also considering the Exmark Lazer CT at about $4800. Your input is greatly appreciated.
