I am dealing with my dealer on a new (different) lawnmower. I currently have a 2005 GX345 54in cut with 254hrs. My two options are a new X540 54in cut or a 2006 X720 62in cut with 265hrs no PTO no 3ph. I mow three acres. My main question is which one is the best value and would be worth more in 3-4yrs? I'm getting $3,300 on my trade and bringing $3,000 to the table total $6,300 for each option. What should I do looking for any help and advice.
