I own a 2006 Ferris Rider that has about 500 hours on it. I want to sell it and unsure about the value. I paid roughly 8500.00 for it. It has a 25hp liquid cooled Kawy. The machine has given me a few problems already. But the main problem is the service I am getting, or should I say not getting from the place I purchased the mower. They ALWAYS take too long and there is very rarely a loner to use. They always have some snide comment and treat me like they are doing me a favor working on my equipment. This machine is under warrranty and they have the b---- to charge me extra for "cleaner and solvents" I am sick and tired-- going back to Scag line again. I have scags, Ferris and Hustler, and Scags have treated me the best. But the service is the straw that broke the camel's back.
