Hello, I have an opportunity to buy a Ferris IS4500 with a Caterpillar Diesel Engine for $9500. The machine only has 45 hours on it and has a 61" Deck. The original owner says he bought it brand new in the middle of last year. Questions: 1. Is this a good deal? 2. Does the IS 4500 have the IDC Deck? 3. Should I be worried about the weight and width of the machine? Thanks!
