Looking for some info and insight on this mower. From what I can find online it seems liike a very heavy duty beast of a machine. I am asking because I am going to look at a used one this week. It has a 33.5hp diesel engine with a 61" deck. Has been used only for residential/personal use and has 38 hours. It has been garaged and from the piics iit looks like it sparkles. I have seen online that new these go for $15K and he is asking $2900. Seems too good to be true. Any comments would be appreciated. Thanks!
