A buddy of mine wants me to go look at a very used 60" Dixie for use on his moms 4 acres of yard. Price is in the $2500.00 area. He thinks I am an expert because I have had a Z/T mower for 18 years. Well I know a lot about my Hustler, but not the Dixie. Any areas I should pay special attention to? What are the weak points if any?
