I'm just starting out and I need some advice on a first mower. I want a ZTR and have John Deere experience. I've located a nearly new F-620 w/ 54" deck and 196 hours, two sets of blades and seat upgrade. I can get it to Iowa for a total of less than $4800.00. I don't need a high dollar ZTR now as I won'thave that many lawns the first year and, being 50, I am too old to walk behind a mower. Any advice? Thank you much.
