I'm new here. That's a great review. I'm on my 3rd JD I put a lot more hours per year on them between 200-250 so they rack up in a hurry. If you want to know how many hours you can really get out of them. I am stuck with the GX345 series because all my attachment won't fit newer models. In 2000 I sold my 1996 345 with 1340 hours and bought a 2000 345 this past summer I sold it to my neighbor it had 2140 hours. I found a 2005 GX345 sitting in a storage locker for 5 years with 112 hrs.
My point being if you take good care of them they will last most people a lifetime.
