Stumbled upon a JD7H17 purchased by a homeowner (supposedly) in April and returned to dealer this week. The model sells new for about $5,100 and the dealer is asking only $4,100. Dealer say the homeowner bought it as a second mower for his wife to use and she was too intimidated. He says it might have only mowed an acre, or so. $1,000 off sounds sweet but scares me a bit. Does anybody know this model well enough to offer some advice as to what else might be the problem? The warranty is effective upon the April purchase, so there is that to fall back on if this is a lemon, or something.
