please don't buy a junk Deere ...There not what they used to be trust me i work on them and i am not happy with them anymore there getting just as bad as everyone elase...If u get one from a dealer u are getting a real Deere not a knock off box store special. But like they said u pay more for the name ...Me I like Murray or a craftsman but out of the choices u have listed there i would pick the 2002 Simplicity Regent lawn tractor. 18hp Kohler Command. with the bagger for 800 not bad But the ZT is good also wish it had the HR meter tho so u can tell if its been used very well
