I just started my lawn business and today I looked at a John Deere GS30. It is last year's model and it was owned by a homeowner-not commercial use. The guy put a Trac-Vac on it and everything seems to be ok. It has right at 30 hrs. on it. My local dealer has it and he's selling it for the guy. Asking price is $2300.00. Is this a good deal? What should I look out for? I don't want to use my personal mower 'cause it's just a homeowner model and I don't want to have to replace it. Any ideas and help would be greatly appreciated.
