I am in the market for a ZTR. I will be mowing yards from 1/4 an acre to 3 acres. Nothing but the Kentucky Blue grass. I have a John Deere HD45 walkbehind with a 48" deck. I am stuck between getting a Toro or Exmark midmount mower with a catcher system or a Walker with a 48" GHS deck and a 52" mulch deck. I know the Walker is a hell of a lot of money but i believe it would be worth it. Whats your opinion?
